Connect 2 Xserve RAIDs to one Xserve

Hello folks,
I have two XServe RAIDs which I bought on eBay and one Xserve G4 with FC RAID controller (2 SFP connectors). I also own a FC switch. Is it possible to connect both XServe RAIDs to the one server and have an access to all arrays there?
Thanks
Robert

1) What does the Fibre say under System Profiler? Do you see SCSI devices hanging off your fibre? Because you should.
2) There is also a Fibre Utility or Fibre in your System preferences depending on your OS version. Check that to see what it says.
3) If everything seems right and nothing is working that's often a sign of LUN masking. You will need a copy of RAID Admin 1.5 (not 1.5.1) to check for LUN masking if you start to suspect it as it was removed in v1.5.1.
3a) There can also be zoning on your FC switch and other things partitioning up your network.
4) Hook up RAID Admin to the machine over ethernet (if you haven't already) to get a look at the RAID internals.
As a sanity check I would start by plugging the RAID sides directly into the computer and eliminating the switch as a factor. That should start to narrow down the variables quickly. If you're getting communication and negotiation but no visibility I would suspect LUN masking. If you get volume visibility through the cable but not the switch then look at the switch.
Good luck,

How to connect multiple Xserve Raid for Best Performance

I like to get an idea how to connect multiple Xserve Raid to get the best performance for FCP to do multiple stream HD.

Again, for storage (and retrieval), FireWire 400 should be fast enough. If you are encoding video directly to the external drive, then FireWire 800 would probably be beneficial. But as long as the processing of the video is taking place on the fast internal SATA drive, and then you are storing files on the external drive, FireWire 400 should be fine.
Instead of speculating about whether it will work well or not, you need to set it up and try your typical work flow. That is the only way you will know for sure if performance is acceptable or not.
For Time Machine, you should use a single 1.5TB drive. It is likely that by the time your backup needs comes close to exceeding that space, you will be able to buy a 3TB (or larger) single drive for the same cost. Also, I would not trust a RAID where the interaction between the two drives is through two USB cables and a hub. If your primary storage drive fails, you need your backup to be something that is simple and reliable.
Oh, and there should be no problem with the adapter, if you already have it and it works.
Edit: If those two external drives came formatted for Windows, make sure you have use Disk Utility Partition tab to repartition and reformat the drive. When you select the drive in the Disk Utility sidebar, at the bottom of the screen +Partition Map Scheme+ should say *GUID Partition Table*. When you select the volume under the drive in the sidebar, Format should say *Mac OS Extended (Journaled)*.

Is it possible to directly connect two Xserves with a Promise VTrak E610fD via Fibre?

I have two Xserves and I'd like to connect them with a Promise VTrak E610fD. As this storage has two controllers, I'd like to connect both Xserve with both controllers. Is this setup possible? Can I access (read and write) the same disk array with both Xserves simultaneously (Xsan?) or do I have to create two separate arrays?

Hello bleistift, and welcome to the AppleBoards,
Fibre channel is SCSI which means that any device connected by fibre assumes it is in sole control of that device. When you attach more than one machine via fibre both machines assume they are in control and unexpected behaviors and data corruption ensues. SAN (like Apple's XSAN) provides a layer of arbitration over the shares allowing multiple fibre connections to play nicely with one another while still being connected over fibre.
You could easily connect two machines to a single RAID box if they are accessing different RAID volumes at the same time, but once you start connecting to the same data at the same time you need SAN.

X - couldn't connect to xserver.

hello,
I am trying to install X with fluxbox.

Thanks for the info. I just managed to install Slackware. I kept getting hung up on the kernel install. When I figured out how to install the 2.6.17.13 kernel along with the kernel modules package, everthing else went smoothly. Now I have to figure out how to tell the difference between Slackware packages and all the others and who to trust. After Slackware Arch should be a breeze. See you in a week or so. Ps Slax Live CD looks interesting too.

Ethernet connectivity between server & RAIDs

I'm trying to set up an XServe G5 and 3 XServe RAIDs, using only RAID Admin, not XSan. What I need to know is...when connecting between the 4 via ethernet for setup, admin and such, should the switch used be a standard Level 2 switch, or does it need Level 3/4 routing capability? This will be completely separate from the corporate network being served by the G5. Thanks!

I connect my Xserve RAIDs to my normal data network, using whatever switch is closest and/or has room, whether it's the CISCO Catalyst or the NetGear one. It doesn't matter what switch, just that it's accessible to me when I am configuring and monitoring them. For me, that means statically assigning IPs and naming them appropriately (XSR01, XSR02, etc). You can use DHCP but I had a problem once when I was upgrading the firmware and my DHCP server was down, so as a rule I take everything off DHCP that I can. And to reiterate, even though they are cabled via ethernet to my Gig switches on my data network (as opposed to Xsan metadata) the real data flows through the fibre channel, not through the CAT5 cables.

Connecting a G-Raid to Time Capsule

I am trying to connect a G-Raid disk to the USB port on the time capsule, but I cannot see the G-Raid disk to configure for use using time machine. Any ideas?

That drive should be usable that way, but may require a powered USB hub. The port on the TC is vastly underpowered; most self-powered drives will work without help, but some of the larger ones won't.
There's nothing in any Apple tech articles, but I've read that a partition over about 2.2 GB either may not be recognized on the TC or you may only be able to use the first 2.2 GB or so.
Try a powered hub; if that doesn't work, try spliting the HD into 2 partitions (connect directly to your Mac to do that) and see if it's recognised that way, with the powered hub. If not, there may be a problem with the port or other innards of the TC.
Note that backups can't "span" from the TC's HD to another volume; for any one Mac, you can back up to either the TC's internal HD or the external HD (unlike the TC's internal HD, you can partition the external).
When connected to the TC, it should show up in Airport Utility something like this (a 500 GB Seagate with 6 partitions):
EDIT: Be sure the drive is formatted for a Mac -- any variant of Mac OS Extended.

Do you mean that there are several wireless networks within range, and you don't want it switching between them?

A connection was abortively closed after one of the peers sent an rst packet

Hello,
i have a dvr on netwoek that is wok fine. i tried to publish it over internet.
i have tmg with two wan connections(load Balancing) and two internal networks.
i create a server application rule and and but dvr protcols on it.
when i try to open it from outside it's not working. on tmg log it's give me this error:
A connection was closed because no SYN/ACK reply was received from the server.
also with others dvr i get this error:
a connection was abortively closed after one of the peers sent an rst packet
i tired to read all post on forums but i didn't get a solution for it.
please not that the network rule from internal to external is route and the publish rule is set to make the request is from local host.
so whats the problem?
thanks.

Hi,
Thank you for your post here.
As far as i know, if you would like to publish server located in internal, you need to set the relationship between internal and external as NAT.

I have two children each with an ipod which has FaceTime - I have the iphone 4s with FaceTime. All of these devices are connected to itunes through the one account. How do I set up the FaceTime on the two ipods so as it doesn't ring both of them?

I have two children each with an ipod which has FaceTime - I have the iphone 4s with FaceTime. All of these devices are connected to itunes through the one account. How do I set up the FaceTime on the two ipods so as it doesn't ring both of them?

I started to do that then it said that this will become their apple I.D or similar and then I thought that will disconnect them from the same iTunes? I want them still on my iTunes as they are only young (8 and 10)? Or have I got this all wrong and even if I do set them up with a different e-mail will they still be on my itunes? For example if they want to purchase an App will it still go through my account even if they use their ipod?

How to connect many devices with only one FW800 port in iMac?

Hi,
I am upgrading to a new Intel iMac from a 2004 vintage Dual2.0GHz PowerMac. I currently have 8x d2 Quadra drives chained by FW800, and 2x Iomega drives connected vis FW400 hub which also connects HD cams.
My questions is that with only one FW800 port in iMac, I think my devices connectivity is the following?
(1) Get a FW 800 hub (I can only find 2 port ones at the Apple store and BestBuy)
(2) Connect the d2 Quadras to one port of the FW800 hub
(3) Get a FW 800 to FW 400 cable
(4) Connect my 6 port FW400 hub to the 2nd port of the FW800 hub
Thanks for reviewing this solution, and I would also appreciate other suggestions or hear about your experiences if you have a similar set-up.
Will

In addition to your listed considerations, you should consider the following.
Many storage needs do not required FireWire 800 speed. For example, USB 2.0 works fine for your Time Machine backup drive. If you are just storing user data such as your iPhoto or iTunes media files, USB 2.0 is more than fast enough. So, as much as possible, if any of those external drives have USB 2.0 connections and the data storage does not need FireWire 800 speed, offload as much as possible to USB 2.0. I used to be a +FireWire snob+, but since getting an Intel iMac, I find that USB 2.0 works quite well for most data storage purposes.
There are new hard drives that are power efficient and as large as 2TB. Consolidate your data storage needs onto a smaller number of very large drives, partitioned as needed. This will make your setup more reliable (smaller number drives), and save reduce power consumption. If any of your current externals are SATA, you can probably replace the existing drive with an extra large one.
So, I think you setup should be, extra large FireWire 800 drive connected to the FireWire 800 port directly. Using a 9-pin to 6-pin cable, connect the FireWire 400 hub. Connect any non-storage FireWire 400 devices there. Do some data transfer testing to make sure having the 400 hub there on the chain does not cause the 800 connection to slow down.
Connect other drives as needed using USB 2.0, existing or new. Retire the smaller of your external drives.

I have 2 ipod touch 3rd gen. Cannot connect to my wifi. One will connect with neighbor's unsecure network..neither connect with my secured network

I have 2 ipod touch 3rd generation. Cannot connect to my wifi. One will connect on and off to my neighbor's unsecure wifi but neither will connect to my secured wifi. All my wireless computers connect plus my Ipad connects. They did connect at one time but haven't used them for anything but audio books which connect through Itunes on my computer. It shows my secured network name. When I originally connected them it was another rather with other security but since then I have bought new equipment. My Ipad and my printers just automatically connect. I have put in the Ip information plus but still no luck.

Trying to connect HP officejet all-in-one! assitant does not support router??

I am trying to connect HPOfficejet 7410 All-in-One which is wirless enabled to my wireless netowork. Getting message," HP NETWORK ASSISTANT does not currently support the router that is connected to your system." Does this mean that I cannot setup this printer with the router I have? Or is there another way I can connect it without using the Network assistant? The router I have is a Linksys Router Model # WRT110 . I have tried to find another router that was in the list of "supported routers" with no luck. I have looked everywhere. Please if someone could help! Let me know if you need more info to answer my question. Thanks!

Actually, its not that the youre router is not ocompatible with the HP Network Assistant. Maybe yuore router has a very secure network security thats why the wireless assistant could not connect the printer to youre router
- The other way to connect the printer to your wireless network is to run the wireless setup wizard on the printer.
- Step 1. Press the set up button on the printer and press the right arrow then navigate & look for netwok menu then press ok.
- Step 2. press the right arrow and look for wireless setup wizard
- it will look for youre wireless router and try to select your router the enter the security key(WEP or WPA) if you have one.
- after that it will prompt you that the printer is connected to your network

Trying to connect a second printer (this one wireless) through airport extreme.

I am such a dufus about anything related to setup! Can I have two printers on my network, one connected by a cable and one wirelessly? I just purchased a second printer for my home office so that I can access both printers from my MacBook Air. The second printer is a Brother wireless one, and am trying to do the setup but can't figure out how. I got to the step about the printer needing to "detect which mode - WiFi Protected Setup Mode or AOSS - your access oint/router uses...I pushed the little wireless setup button at the back of airport extreme, but keep getting an error message that says the printer "cannot detect a WLAN access point/router that has WPS or AOSS enabled."

Hello Gee Money. Welcome to the Apple Discussions!
Chances are pretty good that the signal from the 802.11n AirPort Extreme Base Station (AEBSn) down to the MacBook may not be sufficient three floors down.
I suggest downloading a copy of iStumbler. Use iStumbler's Inspector feature (select Edit > Inspector from iStumbler's menu) to determine the Signal-to-Noise Ratio (SNR) at different points around your house, by performing a simple RF site survey. Within the Inspector, note the values for "signal" & "noise" at these locations. Start with your MacBook near the AEBSn, note the readings, and then, choose the locations where you will typically use your MacBook to access the Internet ... especially the location three floors below.
SNR is the signal level (in dBm) minus the noise level (in dBm). For example, a signal level of -53dBm measured near an access point and typical noise level of -90dBm yields a SNR of 37dB, a healthy value for wireless LANs.
The SNR, as measured from the MacBook, decreases as the range to the base station increases because of applicable free space loss. Also an increase in RF interference from microwave ovens and cordless phones, which increases the noise level, also decreases SNR.
SNR Guideline
o 40dB+ SNR = Excellent signal
o 25dB to 40dB SNR = Very good signal
o 15dB to 25dB SNR = Low signal
o 10dB to 15dB SNR = Very low signal
o 5dB to 10dB SNR = No signal
If the SNR is 20dB+ at each of these locations, then you should be getting reasonable performance from your AirPort. If less, either try to locate the source of the Wi-Fi interference or try relocating either the base station or the wireless clients until they are within a 20dB SNR range.
