AP best throughput
What is the best way to config AP 1230 for best throughput I have a problem with the performance on WL network as is very poor when more than 10 client are use the AP.
Performance issues can be due to various factors affecting the RF environment. The major contributor being RF interference. Do you have any other WLAN close to your network?
You will find some useful troubleshooting tips in this document. http://www.cisco.com/en/US/products/hw/wireless/ps441/products_tech_note09186a00800a86d7.shtml

Best Throughput for RAID - Internal SATA vs. PCI RAID Card
Hi, we're upgrading our old server, which has been on an upgraded G4. We put 3 SATA drives in it, connected to a Highpoint 1820a RAID card running RAID 5.
We're moving this to an older G5 1.6 GHz model (2003). It currently has 2 internal SATA drive bays, but I know can be expanded with an adapter kit. It also has just plain PCI slots (not PCI-X or PCIe).
So I'm wondering what would provide better performance (throughput I guess):
• Using the 2 internal bays with a software RAID 1?
• Putting our old Highpoint RAID card in the PCI slot and running RAID 1 or possibly RAID 5 (with another drive)?
I know the RAID card doesn't use the processor for RAID functions, but I think in a RAID 1 it's fairly minimal, correct? I'm mostly wondering if the older basic PCI slot would bet the bottleneck in a fast system compared to the onboard SATA controllers?
THANKS!Well, we're most concerned with data security and reliability. We're not streaming video or anything else that would demand extreme throughput. The server is mostly serving files to 4-5 users. So I imagine the performance gains would only be noticed when opening/closing files off the server, correct?
And we already own the Highpoint card, which has 8 internal SATA ports, so we'll probably use this. It works fine on PCI bus. So we can run this with 4 drives in either two RAID 1s (boot & files); a RAID 5, or a RAID 10.
We'll probably stick with Western Digital or Seagate 'enterprise' SATA drives, such as the WD RE3.
So, do you think we would see much real-world difference between the different RAID options (RAID 1 software, RAID 1 hardware, RAID 5 hardware, RAID 10 hardware)?
Thanks! -
Looking for some guidance here... I need a USB adapter to "test" and demonstrate the 3700 802.11ac AP's in front of customers and I want something that is going to give me the best throughput possible... but also be reliable.
I know I will need to be in close proximity of the AP and I know that I would get better throughput with an internal wireless adapter but one of the requirements is that i need to demo with a USB adapter.
What have you guys used and what would you recommend I use or stay away from?
Thanks in advance!Ended up purchasing a Rosewill AC1200UBE 2.4/5GHz USB3.0 adapter on Amazon ~$40
The adapter specs state "Data Rates of up to 300Mbps" for 2.4GHz and "up to 867Mbps" for 5GHz
Testing between that and another laptop, through a Meraki MR34 showed actual throughput of 400Mbps from 10 feet away and just shy of 300Mbps 2 (drywall) offices away with the door closed. 25-30 feet down the hall in our office building I got about 175-185mbps throughput.
Not too bad, considering it's only rated for a Data Rate of 867Mbps and not the full 1.3Gbps. I'm guessing the adapter only supports 2 spatial streams.
Anyway... just thought I'd throw that info out there in case anyone can use it.
Attached is a snapshot from DUMeter running on the laptop with the wireless card. DU Meter running on the laptop that the traffic generator was pointing toward also showed the same results. -
Setting up Multiple SSID's & VLAN
I have a Cisco 1230 AP along with a Sonic Wall TZ 210 and a Linksys SFE 2010P switch. On my AP I have created 2 SSID's. and 2 VLAN's. The first SSID is being broadcasted and has WPA encryption on it for our Corporate USers. The Second SSID is a Guest SSID and too is being broadcasted. I can make a laptop connect to the 1st SSID, but for some reason the 2nd SSID nothing will connect to it. The first SSID is associated to VLAN1 and the 2nd SSID is associated to VLAN2. VLAN1 has WPA encryption on it. VLAN2 is setup as Open and no Encryption. Any ideas?
My next question is how to I configure traffic on this AP with the other equipment mentioned? On my sonicwall we have segmented port6 on it to be a different subnet from the corporate subnet. On the Linksys switch I have enable VLANS on port2 and port48 which are on VLAN2. All other ports are on VLAN1. The AP connects to Ports 2 on the linksys switch and port 48 connects to port 6 on the Sonic Wall. When a corporate user connects to SSID1 I want them to be able to connect to the Corporate subnet. When a guest connects to SSID2 I want them to connect to the segmented guest network to only have Internet Access.
Hope this makes sense!
Below is my config on the AP. I am really only familiar with the IOS web interface so if you can explain it using that I'd appreciate it.

Question re: multiple wireless devices and the Duel Band Airport Extreme
I recently purchased the new duel-band Airport Extreme. Prior to that I had the single band Airport Extreme. I’m a bit confused about how it works and have spent a good bit of time trying to find the answers on the web, but nothing really addresses my specific question so I’m coming to the experts.
I have a number of wireless devices throughout my house… a couple of Roku boxes, two iPads, two iPods running Pandora, a MacBook and an older model Apple TV etc.
Both of the iPods are 802.11 G. The iPads can handle N.
One Roku is 802.11 G and the other can handle N.
I am confused about configuring the Airport Extreme. It’s my understanding that if I just go with the basic setup of creating a network and selecting Automatic for the Radio Mode and Channel that all of my devices will automatically connect to the most appropriate band for the best throughput for that particular device.
I have tried configuring the Airport Extreme as I mentioned above, as well as setting it up with the 5GHz Network Name field selected. I gave this a different name so I would be able to distinguish between the two networks when selecting one on my iPad. I will refer to the fist configuration as Setup A and the second (naming the 5 GHZ Network ) as Setup B.
When I use Setup A all of my devices show one available network to connect to. I select that network and all is well.
When I use Setup B the devices show two available networks, the original and the one I named on the 5GHz Network Name Filed.
My iPod’s ( 802.11 G ) only display the name of the first network, but my iPad’s show both, and I can select either. The signal strength on the 5GHz channel only dislplays two bars on the signal strength indicator icon, but the other network is full bars.
When I use Setup A, is my iPad, Roku and MacBook automatically selecting the 5GHz AND the N connection? How do I know that it’s not using the G band? Is it best to just go with the automatic settings and trust that I’m getting the best connections? How does it know weather to connect to the 2.4 GHz or 5 GHz. What determines that ?
Sorry for the rambling questions but the more I think about it the more confused I get about all of the possible combinations of connectivity possibilities.
I appreciate any attempts at making this a “teachable moment” for me :- )
Thanks !
Chuck

The signal strength on the 5GHz channel only dislplays two bars on the signal strength indicator icon, but the other network is full bars.
Not surprising, because the much higher frequency 5 GHz signals are absorbed much more quickly by any obstructions than 2.4 GHz signals. Everything is a trade off. In return for higher speeds, you must give up distance capability and penetration power with 5 GHz. It's not exactly true that you have to have a line-of-sight arrangement between the router and computer with 5 GHz, but many users are finding that to be the case for good, reliable performance.
How does it know weather to connect to the 2.4 GHz or 5 GHz. What determines that ?
The signal strength. If your computer is capable of connecting at both 2.4 GHz and 5 GHz, it will choose the band with the higher signal strength...assuming that both bands have the same network name. The only way you can "force" a device to connect to the 5 GHz band is set it up with a different name and point your computer to that specific network.
For most users, the way to go is setup both bands with the same wireless network name and let devices connect to the strongest signal automatically. -
Can I use a Time Capsule to extend my wireless network.
Hi, I have just bought a 3TB time capsule as my old (flat style) 500GB TC is reaching full capacity. The old style TC will then be surplus to requirements as a data storage unit, at least for myself, though it might be useful for my son to use as his Time Capsule.
Ideally, as we have a wireless 'blind spot' out in the rear extension of the house, it would be useful to use the unit to extend my wireless network (and also use it as a separate TC if possible). Is this possible? If it is how would I go about it?
Hope someone can help . . . .
Cheers
JohnIs it possible for you to consider connecting the Time Capsules together using a wired Ethernet connection?
Here is what Apple has to say in their support document about extending:
Adding Wi-Fi base stations when it is unnecessary can reduce Wi-Fi throughput because the Wi-Fi network will require more data management overhead. The network configuration also becomes more complex. In the case of a wirelessly extended network, throughput may be reduced to less than 60 percent of that of a single device. The general rule is to keep the Wi-Fi network as simple as possible. You can accomplish this by using the minimum number of Wi-Fi base stations required to service the physical network area and by using Ethernet wherever possible.
Extending the range of your Wi-Fi network by connecting Wi-Fi base stations together using Ethernet is always the best option, and will provide the best throughput.

4 Wi-Fi Tips from Former Apple Wi-Fi Engineer
Hi, I thought this was a real neat little article from Alf Watt, former Apple Wi-Fi engineer and creator of the fantastic Wi-Fi utility, iStumbler, Thought I would share.
Alf Watt, former Apple Wi-Fi engineer and creator of the fantastic Wi-Fi utility, iStumbler, joined us on this week's Mac Geek Gab 509 to talk all things Wi-Fi. The episode contains a bunch of juicy Wi-Fi tips and I highly recommend you give it a listen, but for now our four favorite tips are listed below. Think of this as the MGG 509 Cliff's Notes... and make sure you read, erm, listen to the whole thing, too. On to the tips:
1. Use same SSID for all radios on the same network (be they 2.4GHz or 5GHz). If you have one network in your home but have either multiple routers/access points for better coverage or multiple radios in one access point, the advice is the same: use the same SSID (wireless network name) for all of them and let the client devices each decide which is best to use.
Apple devices choose networks by your preferred order. Period. If you have multiple networks of different names your Mac or iPhone will always choose the first in your iCloud-synced "Preferred Networks" list even if this one isn't going to give you the best bandwidth. If you have the network name/SSID the same then it will chose the radio that it predicts will give the best throughput (which isn't always the one with the best signal, but that's an even geekier discussion you can hear in the show). Make all the Wi-Fi networks in your home the same. Your life will be better for it.
2. Deal with congestion with more access points using less power. In response to a listener's query about how best to deal with having lots of access points in a small location, say an apartment building, the best thing to do is to actually increase the number of access points but lower the transmit power on each so as to keep them from interfering with each other. It's good if your neighbors do this, too, of course, but it will help even if it's just you. We recommend using Powerline adapters to connect all of your access points together to avoid the headaches of just extending Wi-Fi.
Another helpful option is to use 5Ghz channels where possible. The higher frequency band doesn't go through walls as well and may be exactly what the Wi-Fi doctor ordered in highly-congested areas (and when we get 60Ghz Wi-Fi, that'll be even more helpful!)
Next: When to use Wide channels and Antenna Orientation.
3. Don't use "Wide" 40MHz channels on 2.4GHz. Some routers (not Apple's) will allow you to use "Wide" channels on the 2.4GHz band. The problem is this band is so congested that you'll likely just wind up making things worse instead of better. Bluetooth lives here, too, and will appreciate the breathing room. Plus, Apple made the decision years ago to not support these wide channels at 2.4GHz, so even if your router allows you to enable it your iPhone and MacBook won't use it.
On your 5GHz radios 40MHz channels are perfectly acceptable (again, your Apple router takes care of this for you). And with 802.11ac (5GHz only) you may wind up using 80MHz or even 160MHz channels. Just remember that current 5GHz implementations only have enough room for TWO (yes, 2) 160MHz channels, so choose wisely. The good news is that current 802.11ac routers use "cognitive radio" technology. This means they listen before they talk and that will ratchet down from 80MHz (or 160MHz) to something lower if they see another router communicating in the same band. Smart.
4. Be smart about antenna orientation. If your router has internal antennas (as most new models do), make sure to use them in their natural orientation. Put simply: if the router has feet, use them as feet (as opposed to laying it on its side). Some routers have feet on two sides and give you placement options, so feel free to capitalize upon this flexibility.
For routers with those adjustable, "rubber ducky" antennas, Alf recommends pointing one straight up and one flat out. This is because radio reception is maximized when both client and access point have matched polarization (antennas pointing along the same plane).
Some client devices have antennas in vertical orientation, some horizontal. The current crop of MacBooks, for example, have their antennas in the black plastic part of the hinge in a horizontal orientation.
Those tips should get you started. Give Mac Geek Gab 509 a listen to learn more about beamforming, the future of Wi-Fi, how your router decides what country it's in (and what channels it can use!), the future of iStumbler (and other products from Alf) ... and more!
Solved!
Go to Solution.Roaming isn't part of the WiFi specification.
While some clients may look for the strongest signal most just look to see if they can connect to the last AP they were connected to.
Some SOHO APs will allow you to set them to reject a connection weaker than -70db.
To get efficient roaming between APs you need commercial AP controllers which monitor the entire network of APs to see which one offers the strongest signal and has the smallest load.
To the best of my knowledge there are no SOHO router/APs that talk to each other which is necessary for effective and seamless roaming. Apple hardware is supposedly better than other brands, but I have never used it.
Most people are better off setting up individual SSIDs for each radio that identifies the location (Upstairs 5, Upstairs 2.4, etc.) so a user can make an intelligent choice of which to connect to. If speed doesn't matter such as when checking and downloading e-mail then any SSID/radio will do. If you want to stream video than the nearest and probably the strongest 5 Ghz AP is what they should connect to.
Changing the names of SSIDs is trivial so if people want to try using all radios with the same SSID they should go for it. If they aren't happy with the results then go to plan B and rename. -

Why this device cannot support 300Mb/s rate in radio 0 of speed ?
i want to setup more than 54 Mb/s when i use my laptop to connect this AP.The 802.11n HT rates apply only to no encryption or WPA2/AES encryption. They do not apply to WEP or WPA encryption. If WEP or TKIP encryption is used, the 1250 series access points and any 802.11n Draft 2.0 clients will not transmit at the HT rates. Legacy rates (802.11a/b/g) will be used for any clients using WEP or TKIP encryption.
Ref.: Release Notes
40MHz Operation
If the throughput you get from a 20-MHz channel isn't enough for your speedy users, you can flip each 5-GHz 11n radio into a bonded-channel configuration.
You can configure 40-MHz operation on the 2.4-GHz radio of the 1250 Series AP, but this isn't recommended or supported. The primary reason against it is that with a wide channel in a band that has so little available spectrum (and so much interference), you make a single AP capable of higher throughput at the expense of performance for all neighboring access points-certainly not the way enterprise WLANs ought to be designed. Also, the vast majority of client chipsets (Intel's, for one) will not support 40-MHz operation in the 2.4-GHz space.
Ref.: Cisco 802.11n Design and Deployment Guidelines
Making the Most of Things
Once you're connected at 802.11n HT rates, you'll want to make sure you don't lose the throughput gains you should be able to achieve. Not all may be within your control, but if you understand the performance implications of these variables, it will help you in baselining your WLAN capabilities.
When your laptops are unplugged, the 11n client will likely try aggressively to save battery power. Depending on client radio and chipset, it's not uncommon to see performance drop by as much as 50 percent. Unless you know how to fully disable this, keep your laptops plugged in if you want maximum performance,
Note: Even if you managed to disable this power save function, most laptop motherboards/chipsets have automated power-saving features that kick in when the laptop is unplugged. At best, these are difficult to disable. Thus, it is strongly recommended that you not do performance testing when clients are battery operated.
As detailed previously, throughput performance may vary as legacy devices are introduced into the 802.11n environment. This is to be expected, but make sure that you find a channel void of all legacy transmissions if you want to test the high-water mark of your new 11n WLAN. If that isn't possible, adjust your expectations accordingly.

In each instance when the profile dropped it aligns perfectly with a single switch off of the modem for 15 mins. In each instance it takes 7-8 weeks to recover.
Far too sensitive to downside and not sensitive enough on upside.
Why is it then we don't have a method of faster recovery ? I can appreciate that the DLM acts to maintain a service but what I cannot accept is the balance it presently exhibits and the faceless nature of its operation.
Right, now that's off my chest I can chill in the summer sun!So what are we saying here?. If you turn just your modem off for over 15 mins it reacts like its 100% stable again and the DLM kicks out and your connection performs and its best throughput or not?. I'm confussed, I have never tried???. So if this is correct I will give it ago, see what results I get!. Anyone given this a try yet?.

Problem getting WinXP machine to connect to Time Capsule
I just changed from DSL to Comcast. Old DSL configuration works:
DSL modem->(ethernet cable) WinXP machine
DSL modem->Time Capsule->wired/wireless to Macbook Pro and wireless to iMac
New configuration:
cable modem->Airport Express->wireless to Time Capsule->(ethernet cable)Win XP machine
cable modem->Airport Express->wireless to Time Capsule->wired/wireless to MacBook Pro and wireless to iMac
Mac clients work fine, XP Client does not connect
I can connect through the Time Capsule to my MacBook with an ethernet cable, so I know the Time Capsule is connected. I did a DHCP release on both Mac machines to get them hooked up to Comcast; did ipconfig /release, ipconfig /renew, on XP machine, also tried "repair connection" but neither worked.
The DSL modem is in the same room with my MacBook and Time Capsule, while the cable modem is downstairs. I used the Airport Express to connect to the cable modem so I could maintain a wired connection between the Time Capsule and my MacBook for Time Machine.
In the past I used the Airport Express to connect the XP machine wirelessly.
Any ideas?I understand it seems backwards, but I'm trying it this way to keep the Time Machine within cable distance of my MacBook so that Time Machine is faster. Is there any real advantage to using the Time Capsule as the base station and the Airport Express as the extender, as opposed to the opposite (as I am doing now?) What configuration is likely to give the best throughput?
Here is what I have:
First floor: cable modem; iMac with its own external drive for Time Machine
Second floor: MacBook with Time Capsule for Time Machine.
The simplest solution seemed to be just to place the Airport Express (which was unused) next to the cable modem and leave the rest alone.
Meanwhile, I tried again to get the winxp machine connected, and it is working. I'm considering getting a second Airport Express for the winxp machine, so I can get rid of the long cable connecting it to the Time Capsule.
I'm marking this as solved since it started working, and I appreciate your taking the time to respond.

External HD reformat interrupted; now I can't use disk
I recently purchased a 2TB Seagate GoFlex external hard drive (connected to my Airport Extreme via ethernet cable) to use at a Time Machine backup. After setting it up per the Seagate instructions, the initial backup was agonizingly slow - just 200 GB in 36 hours. Other discussion topics recommended reformatting the drive using the Partition tab in Disk Utility, making sure the Partition Map Scheme was set to either Apple Partition Map or GUID Partition Table. However, when doing that, the process hung at "waiting for disks to reappear." I accidentally closed out of Disk Utilities, and now I cannot access the disk to complete or re-do the process.
The disk only shows up in Disk Utility if I open up Time Machine and tell it to "Back Up Now", but the backup fails because the disk is unavailable. If I then select the disk in Disk Utilities then select Partition, all selections are grayed out. Any suggestions?Turn off Time Machine by first setting the backup device to None. Next:
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Cick on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Bear in mind that backing up over a network is slow. Even using Gigabit Ethernet the best throughput you will achieve is that of a USB drive which is slower than Firewire 400. 200 GBs in 36 hours sounds about right. However, once the initial backup is done the incremental backups will not take as much time. To avoid the time needed for the initial backup it's advisable to do it by direct connection to the computer's USB or Firewire port rather than over the network.

I need a transfer rate minimum of 9mbps. My AirPort express and 3DTV are on different floors, so I cannot directly connect with an ethernet cable. Can I buy an older AirPort express, use it as a bridge, and connect my TV to it via an ethernet cable?
Hi rockchalker,
Thanks for using Apple Support Communities.
For 802.11n Wi-Fi base stations, creating a roaming network is by far the best choice. This will provide the best throughput between the base stations and your Wi-Fi devices.
If you are unable to build the recommended Roaming network, then a Wirelessly Extended Network is the next best option.
For more information on this, take a look at this article:

Hi friends,
Where can I find documentation for the usage of [*+ INDEX */] in SQL statement?
Thanks,
PeterFirst_Rows
The FIRST_ROWS hint explicitly chooses the approach to optimize response time, that is, minimum resource usage to return the first row. Results will be returned as soon as they are identified.
This hint causes the optimizer to make these choices:
If an index scan is available, the optimizer may choose it over a full table scan.
If an index scan is available, the optimizer may choose a nested loops join over a sort-merge join whenever the associated table is the potential inner table of the nested loops.
If an index scan is made available by an ORDER BY clause, the optimizer may choose it to avoid a sort operation.
The optimizer ignores this hint in SELECT statement blocks that contain any of the following syntax:
set operators (UNION, INTERSECT, MINUS, UNION ALL)
GROUP BY clause
group functions
DISTINCT operator
These statements cannot be optimized for best response time because Oracle must retrieve all rows accessed by the statement before returning the first row. If you specify this hint in any of these statements, the optimizer optimizes for best throughput.
Syntax:
/*+ FIRST_ROWS */
Example:
SELECT /*+ FIRST_ROWS */ emplid, cc_descr, ccnxt_descr
FROM ps_dwad_c_dl_vw
WHERE emplid = '0895801' -
Hi all,
First of all I live in Belgium so I cant preview any of this software:
http://www.microsoft.com/en-us/powerbi/default.aspx
Now most of my customers are SME in the fashion industry and we are going to develop a data warehouse platform where they connect to with a client application to view KPI's, scorecards and dashboards. Most of them have a SQL Server on site now here comes
the challenge.
1) We know how the data warehouse looks like, it will also be made in Sql Server. Now we want to put it in the Cloud so they will always have access to there data. Does it matter where we host it? In a datacenter or Azure?
2) What would be the best way to upload the local data to the warehouse? A VPN connection to the datacenter, webservices?
3) What would be the role of Power BI in this story? Will it only pass the data to the clients (ios app and Excel) so may I see it as a Client tool? or is there a possibility to create the warehouse in Power BI?
Thanks for the clarifications!My experience with the power bi preview and the US only restriction is that it's limited to your email being a .com and selecting 'United States' as your country. So just register a .com domain for a few bucks from a registar that supports email forwarding
and you should be able to get your hands on it :)
re your questions
Can't really help with 1 or 2, but it depends on the size of your data and which option gives you the best throughput and i/o for your money, and whether you plan on using any of the other features that come with azure. I don't see how you could load anything
using webservices though unless your dataset is tiny.
although if i had to make a call, If you're going to be putting it in azure you'll need to use the heavy IO VMs and install sql server. I don't think azure sql can be used for any kind of data warehousing at the moment.. not enough optimisation features
and i don't think it supports backing up/restoring using .BAKs to on-premise and vice versa.
3. both, although the semantic models that are persisted inside PowerBI are limited (excel powerpivot only at the moment - it supports an api generated dataset and a model created in the powerbi designer, but these aren't as feature rich as the full
v2 powerpivot/bism model). The new powerbi preview supports on-premise tabular cubes according to the doco (haven't tested this yet, haven't been able to get the AD working) so it will work as a front end tool. I think it sends the dax direct to the cube
and then visualises the result.

Request for advice configuring/mounting XRAID
I'm asking for some advice about configuring Xserve RAID.
I am not an IT person, but just a researcher and have found
myself in charge of some computing resources.
We have an Xserve RAID - 14 drive, each set of 7 on RAID5 - connected
through fibre switch to an Xserve head node. (The fibre switch is
because we will probably add another Xserve RAID in future)
The intent for the RAID is to hold our data while we do our computations.
We have a small cluster of Xserve cluster nodes for distributed Xgrid and
Matlab computation. I intended to network mount the RAID on each computer
in cluster. All the users will ssh in to a shell, and none will login to
a desktop.
I have just begun to setup the RAID, but ran into some questions that
I thought I would ask for advice before I proceeded.
I have already striped both controllers together with software RAID.
(diskutil createRAID stripe "Journaled HFS+" "RAIDvol" disk2 disk3)
It created the stripe and created the jHFS+ file system, but I didn't
realize it would also mount it in /Volumes/RAIDvol
1. Do people have advice on whether I should keep this mount point?
I had rather thought I would mount in root (/) on head node and
cluster nodes, e.g. /RAIDvol instead of /Volumes/RAIDvol
(And how should I change the mount point? Evidently not through fstab
- should I use NetInfo(niutil) and is that complicated?)
Before I change it from mounting in /Volumes, are there any reasons not to?
(again, no one is going to see a desktop, everyone will ssh into a shell)
2. Should I have striped the disks together, or concatenated them?
(What's the difference? - any performance difference?)
3. Do people have advice on network mounting, AFP vs NFS? What
performance differences should I consider?
Thanks for everyone's help.

Xserve RAID Mac OS X (10.4)
Other OS>1. Do people have advice on whether I should keep this mount point?
By default all external volumes will mount under /Volumes.
It is possible to change, but I'd leave it there, it's not worth the hassle trying to bury it somewhere else, and if no one's logging into the desktop then no one's going to notice it anyway. Since it's being shared to the other clients it can be mounted at any point outside of /Volumes, but I'd leave it in /Volumes on the head node.
Trying to change this will just run into problems later on when Apple change their model.
>2. Should I have striped the disks together, or concatenated them?
(What's the difference? - any performance difference?)
Striping is better than concatenation.
The difference is in how the volume is laid out, and specifically how the data is written to the volumes.
If you write a large contiguous file to a striped volume, a chunk of data (32K by default) is written to the first LUN (half of the array) then the second chunk us written to the second LUN). This alternating pattern gives you the best throughput since the RAID is effectively writing to al 14 disks at once, and can be flushing the buffers on the first 32K while the next 32K of data is being written to the other LUN.
By comparison, concatenation simply appends the second LUN. As you write your file it is all written to the first LUN and it's only when this LUN is full that you start writing to the second LUN. Therefore your throughput is much lower since you're only using half the disks at once.
Concatenation is easier to setup since some volume formats allow you to grow a volume by simply adding more space at the end, whereas slicing requires a reformat, but those are your choices.
>3. Do people have advice on network mounting, AFP vs NFS? What
performance differences should I consider?
Performance is one factor, security is another. NFS doesn't offer any significant security other than which IP addresses are allowed to mount the volume. AFP supports authentication to ensure that the specific user can mount the volume.
This may or may not be relevant to you depending on how the clients are mounting the volumes, and whether you want there to be any crossover between the clients. If they're being mounted at startup (so the volume is always available) I'd probably opt for NFS. Home directories, on the other hand, would be better served via AFP.
Performance wise NFS might have a slight edge, but I've heard others say AFP does, so YMMV.
