New Xserve 24GB memory options

Hello people,
While configuring the new Apple Xserve I was wondering why there is such a big difference in price between 24GB option with 12x2GB and 24GB with 6x4GB!? I understand that the 4GB sticks are a tad more expensive as the 2GB ones but there is a $ 3600 price difference between the two.
Case in which you get the same amount of RAM why would anyone buy the 3x more expensive 4GB option?

Regarding answer 1: So faster means what? 1-2% faster than with 12 dimms or how much faster?
From memory, each additional DIMM on a channel adds 2.5 - 3% overhead, but writes have a higher overhead, so the specifics depend on your usage pattern (e.g. read vs. writes).
Regarding answer 2: No comment. But then again why doesn't apple offer 48GB of RAM in 12x4?
I wondered that myself. Maybe they were scared of showing that price?
Regarding last answer: Are you refering to the economic rules of supply and demand? Because if you are, then i know that when the demand is high the supplier raises the price. Based on this should i conclude that the biggest demand is for 24 GB Xservers with 6x4GB dimms?
No. The laws of supply and demand have two factors to consider. You're assuming that demands is high. I'm saying that supply is low - the 4GB DIMMS are in lower supply than 1 and 2GB DIMMs, therefore they command a higher price. Check any memory vendors' FB-DIMM pricing and you'll see the same (although Apple's pricing is, of course, higher than most).

  • External Fiber Channel Raid options for New Xserve besides Promise V-Trak

    I was wondering if anyone out there knows if there is an alternate option for a External Raid that can be hooked up via 4gb Fiber Channel to my new Xserve. I am really looking for a more cost efficient one than the 12K Promise set up from Apple. My Technology vendor was telling me that you have to use the Promise Raid as it is the only one that a Xserve will control due to Apple's licensing of its drivers etc. for its Fiber channel. Something tells me that this is not true.
    Anyone have any recomendations for a Fiber channel Raid solution in the 6K dollar range?
    thanks,
    Dan

    Find another vendor. Anyone that tells you the Promise is the only RAID that will work clearly doesn't understand the market.
    As for recommendations, you need to include some idea of capacity, either usable or raw. I can find you a lot of options for $6K if you want a 100GB of data. Not so many if you want 100TB.

  • New Xserve in the rack....where do I go from here?

    Well, our shiny new (and unexpectedly deep and heavy) Xserve arrived this morning, and has been installed in the rack cabinet at our new premises. I think I need help knowing where to go from here on a couple of points.....
    I've been wading through pages of PDF manuals, support pages and forums posts and – to be honest – my head's in a mess!! I'm hoping some of you nice folks out there (Camelot provided some very useful advice in previous posts) could offer me some direction, so I can work out what I need to work out, and understand what I'm doing so I can get this beast up and running.
    Having also bought a couple of Netgear GS724T switches, I had planned to setup a 4gbps trunk between the Xserve and the first switch (with a second 4gbps connection between the switches). We will use an Airport Extreme Base Station as our DHCP server, and I will likely assign static IPs to both the switches whilst configuring them for trunk operation. Things are slightly complicated by the fact that our new BT Versatility installation already appears to have a 4-port wireless router bolted on, but I think we can effectively bypass this straight to the AEBS....
    In order to use link aggregation (i.e. the 4gbps connection to the Xserve), will I need to configure Server first using only 1 ethernet connection? Can I do this 'headless' – I have installed all the Admin Tools (and documentation!!) on my MacBook Pro.... Also, can I even use link aggregation in a 'basic' Standard Server configuration, or will I need to use Advanced?
    We choose to purchase 3x 300Gb 15k SAS drives and therefore also have the RAID card installed. My understanding is that the Server software will be installed in drive 1 (left hand bay), and simply needs 'configured' (did I say 'simply'??!). I also believe I could – without re-installing the OS – changed the setup to RAID5 if I wanted to. I think I need to do this using Disk Utility whilst the Xserve is booted via the install DVD – correct? Can I setup disk mirroring without re-installing, and is the process the same (i.e. boot from DVD, change the setup, re-boot)?
    We run Filemaker Server, and I wondered which initial setup option would be optimal – NO raid, with the OS on one drive, and the database file(s) on another; or one big RAID5 volume with everything on it? I guess with 3 internal drives, we could go for a single drive (OS) plus a 2-drive RAID for files (either mirrored or striped for speed). If we bolt on a couple of 500Gb Firewire drives which we have 'spare' that would allow for backups of both volumes.....?
    Putting everything into consideration, I want to take 'baby steps' with the setup, until I get my head round everything. Initially, all we need is Filemaker and remote access to our databases (through VPN I guess), although I want to add web/mail/iCal etc..etc.. once we've settled into the new offices.
    The whole DNS thing scares me a bit. I can arrange reverse DNS with BT, and point our domain (via FastHosts) to our public IP address so we can run our own Web and Email server. I'm just not convinced this won't be a security vulnerability.....
    I'm a long time Mac user, but I've never used Server, and I rarely use Terminal. This new Xserve venture is exciting, but it also feels a bit un-nerving.... and advice, input and further reading suggestions would be gratefully received!
    Thanks in advance.

    In order to use link aggregation (i.e. the 4gbps connection to the Xserve), will I need to configure Server first using only 1 ethernet connection?
    Ahh, setting up Link Aggregation while headless is always a concern since it will affect the network connection you're using to administer the box. It is possible to do, it just takes some planning. If you can, configure the link over the serial port using networksetup, or put a monitor on the server temporarily.
    Also, can I even use link aggregation in a 'basic' Standard Server configuration, or will I need to use Advanced?
    I believe so - 'basic' vs. 'Advanced' only controls the set of services that are run and simplifies the admin interface somewhat. I don't think it has any effect on the underlying network setup but I might be wrong (I've never used anything but advanced).
    I also believe I could – without re-installing the OS – changed the setup to RAID5 if I wanted to
    No, that is not possible. Converting to RAID 5 will destroy the current config and reformat the drives. You can migrate to a RAID 1 or RAID 0 array, but not to RAID 5.
    Can I setup disk mirroring without re-installing, and is the process the same (i.e. boot from DVD, change the setup, re-boot)?
    For simple mirroring you can use RAID Admin's Migrate option to migrate the current single drive to a new mirror on the other two drives. The you can re-use the original drive.
    We run Filemaker Server, and I wondered which initial setup option would be optimal
    In general, RAID 5 is not recommended for database use - or any other use that requires a lot of random writes, although it does depend on volume - if your traffic is sufficiently light it might not be an issue.
    Other than that, for most people the data is most important, so that should be mirrored. It's reasonably easy to reinstall the OS (at least compared to rebuilding all your data.
    Putting everything into consideration, I want to take 'baby steps' with the setup.
    To start, focus on the disks. Everything else (applications, services, network, etc.) can be reworked easily later on. Not so with the disks.
    The whole DNS thing scares me a bit.
    Use BT for your public DNS for sure, but you'll definitely benefit from having working internal DNS, and that's pretty easy to manage, at least for small networks.
    so what DNS name do I use locally when configuring Server?
    You can use anything you like. You can use ourcompany.com - the same as your public domain, but just have to realize that 'server.ourcompany.com' may mean different things depending on whether you're inside your network querying your own DNS server, or external querying BTs (BT will return 12.34.56.78 while your internal DNS would return the 192.168.100.x address).
    This confuses me (from setup guide):
    Ignore the statement in the setup guide. It's perfectly valid to have 'server.domain.com' hosting email for [email protected].
    Do I need to consult our ISP about what DNS name I should give our server
    If you're running your own internal DNS then no, not at all.
    You only need to involve BT for any externally-available hostnames (and they don't even have to match your internal names - it's fine to have 'server.domain.com' on your internal DNS but no 'server.domain.com' in your public DNS, it just means no one can get to 'server.domain.com' from outside your network.
    Filemaker recommends you use the scheduling facility in FMServer for backups, and not system backups
    This is absolutely the case - it's hard to make backups of active/open files, especially databases. Any backup takes time - you read the first byte at time 0, but might not get to the last byte until several minutes later - and you have to consider what happens to changes in between (some may be backed up if they happened before the backup reached that part of the file, others might not, leading to an inconsistent file).
    Filemaker's backup method ensures you have a valid backup of the data.
    I'm now thinking that mirroring the OS on drive 2 might be a good idea, whilst storing Filemaker files in a 'Databases' folder on drive 3 (which is backed up my FMServer schedule). Other 'Shared' folder(s) on drive 3 could be backed up via Time Machine to an external FW800 drive......
    This really depends on the frequency of change in your database. If it's mostly reads and not many inserts/updates, then reverting to yesterdays backup might not be a problem, but if your data changes constantly it might not be as good.

  • TOOLS MEMORY option missing in N93

    Hi,
    I have bought a new memory card and I am unable to format the card because TOOLS>MEMORY option is not available in my N93. Can you tell me how to format the SD card using N93 phone.

    Slightly confused - why wouldn't it be available? Is it a limitation of the browser being unable to activate the plug-ins which are part of Adobe Acrobat X Standard? It's just functionality for altering the layouts of PDFs, page numbering, etc. Should be fairly standard?

  • New Xserve, Setting Everyone Up

    Alright, so during New Years weekend, our current Xserve died. We received our new Xserve 10.6 and got it setup and currently we just created a few users, put them in a group called, "Office" and it is sharing out a folder on our Raid 5 array that everyone needs access to.
    What I'm wanting to do is properly setup and configure this bad boy so that afp works flawlessly and everyone can get to the folder(s) they need to, but not into one anothers private user folder.
    Before, users when they logged into their local machine, were authenticating against the server... I dont know how to move them to the new server so when they change their password on their local mac mini/imac/mbp it changes on the server etc.
    Someone point me to some docs that could help explain this?

    Hey Eileen, Seems as though you have the same legitimate problem as any other new computer purchaser. The way that I would suggest you do it is as follows:
    1) When you plug in the iPod, in itunes it will give you a window, telling about the iPod being linked to another computer and would you like to change it to this computer, select no.
    2) The other pop-up that will showup will be the F:\ or E:\ drive. In this window, go Tools -> Folder Options -> And Select the Radio Button that will ask you to show hidden files and folders. There will be a new folder that will show up on your drive.
    3) Click once on this folder, on the side taks pane, click Copy The Selected Files. Move these files to somewhere easy to find.
    4) One they are copied go into itunes, Select File, Add Folder to Library, and the new file that you added to the computer from the ipod. Select Ok, and your songs should begin to import into the itunes Library. When this is done unplug and plug back in the ipod and when it asks you this time to sync with this library, select yes, and your music will be erased from the ipod and reinstated as a new library in unison with the songs you have on your new Laptop!
    Hope this was helpful.

  • New Xserve automatic startup what I plug power cable

    I just got a new Xserve (Intel base ) , and I found it's really stranger . Every time , I plug the power cable , it will automatic power on and startup even I have press the power button .
    Use software update , reset pmu , It don't work .

    Is there anybody has same issue ?

    Jing Hui Zhou-
    Greetings and welcome.
    Unless there is a physical problem, perhaps it is a setting. Check System Preferences->Energy Saver->Options and uncheck the box that says "restart automatically after a power failure".
    If that isn't it, perhaps there is a hardware problem.

  • Questions on new XServe

    Apologies for the lengthy post.
    We're looking to update an older dual G5 XServe to a new Nehalem model. Our current server handles file sharing (AFP & SMB) and is our OD Master (we have 5 other XServes). It's connected via Fibre to an XServe Raid configured with 4 active drives (250 GB each) and a standby backup drive. It total we have @ 700 GB of usable storage. We have a cloned system drive in the machine, and another offsite. We also have extensive Firewire data backups, including offsite.
    We're looking to replace this with a Dual Quad core machine but I'm still mulling over configurations. As the XServe RAID has been removed from the support list, I'm considering removing it from the equation and perhaps just use it for some non critical archiving. It has been wonderfully reliable in the 5 odd years we've had it.
    For the new server I was thinking 3x 1TB drives (& Raid Card) which I suspect would give @ 2TB of storage (more than enough for us - the 700 GB is already adequate but if we're going to upgrade we may as well expand a bit as well).
    And now for the questions...
    Would I be correct in assuming I could expect similar/better performance from the new drives as opposed to the old XServe RAID? Will the G5 XServe's Fibre Card fit the new XServe?
    Are the Solid State Drives user swappable? I was thinking perhaps a second SS drive with a cloned system as a backup.
    Can a boot partition be setup on this RAID setup as a backup to the Solid State Drive? What's the general feeling with regards SS Drives? Are they worth considering or should I just stick to 'conventional' technology?
    Will these XServes boot OK from a firewire device?
    Any advice, suggestions or personal experiences would be appreciated.
    many thanks

    Would I be correct in assuming I could expect similar/better performance from the new drives as opposed to the old XServe RAID?
    Comparable direct-attached storage (DAS) disk storage tends to be faster than SAN storage, yes.
    And you can connect DAS via SAS or SAS RAID PCIe controller, an older PCI-X controller, or via FireWire or USB buses. PCIe disk interconnects will be the fastest path, and USB the slowest.
    Here, I'd tend to consider the Apple RAID controller or a PCIe RAID controller if I needed extra bays.
    Will the G5 XServe's Fibre Card fit the new XServe?
    I don't know. That probably depends on the card, but it's certainly worth a try. Ensure you have the right slot in the new box; you've probably got a PCI-X FC SAN card here, and you'd thus need a PCI-X riser on the new box. Or punt and get a newer PCIe FC SAN card. Put another way, I'd ask Apple to confirm your particular card will work when carried forward, or wait for another responder here.
    Are the Solid State Drives user swappable? I was thinking perhaps a second SS drive with a cloned system as a backup.
    The Xserve drive bays are user swappable.
    Do you need SSD? If you're on your current box and are not already I/O bound, I'd guess not. And the newer HDD drives are faster, too.
    Can a boot partition be setup on this RAID setup as a backup to the Solid State Drive? What's the general feeling with regards SS Drives? Are they worth considering or should I just stick to 'conventional' technology?
    There is flexibility in what you boot your Xserve box off of, yes.
    I've been using SSD off and on for around twenty years in its various incarnations. Back when there was battery-backed DSSI drives (don't ask) and SCSI-1 RAM-based SSD gear.
    Whether SSD is appropriate really depends on what you need for I/O rates. An SSD is one piece of a puzzle of gaining faster I/O, and some of the other available pieces can be faster disks, striping (RAID-0), faster controllers, or faster controllers with bigger caches, or more and larger host caches. If your applications are disk-bound, definitely consider it. But if you're not being limited by the disk I/O speeds for your box, then SSD doesn't (usually) make as much sense.
    (There are other cases where SSD can be appropriate. SSD is more tolerant of getting bounced around than HDD, which is why you see it in laptops and in rough-service and mil-spec environments such as aircraft-mounted computer servers. With an HDD, one good head-slap can ruin your whole day. But I digress.)
    Will these XServes boot OK from a firewire device?
    AFAIK, yes. I haven't had to do that, but that's been a longstanding feature of Xserve boxes.
    Any advice, suggestions or personal experiences would be appreciated.
    I'd relax; the Nehalem-class processors are screaming-fast boxes, and with massively better I/O paths than Intel has had available before.
    Ensure your LAN is Gigabit Ethernet or IEEE 802.11n 5 GHz dual-slot, too. Upgrade from any existing 100 Mb LAN and from pre-n WiFi networking.

  • New Xserve:  Which Rack to Buy?

    Hey guys,
    We just bought a new Xserve Quad-Core w/ a Raid Card and 3 2TB HDs. I'm trying to figure out the best small rack to buy for it. The only thing that we'll be mounting in it for the time being is the Xserve.
    First, I bought this rack: http://www.amazon.com/Solid-Versatile-Mounting-Servers-Network/dp/B000NMDIPE/ref =cmcmu_pg_header
    The Xserve mount kit (square hole) fit on the inside flanges, but obviously didn't work because the Xserve could not slide in all the way. Then I ordered another rack:
    http://www.tripplite.com/en/products/model.cfm?txtModelID=4025
    Same situation. It's obviously because of the fact that the uprights have a "C" shape and not an "L" shape. So I need a small, Xserve compatible rack recommendation. Preferably open and not an enclosure, and under $500. Any suggestions?

    I personally think that for a 1u xserve you should get an xrack pro. There a little more expensive but are amazing i think. They pretty much sound proof the xserve and keep it very cool. They also come with a glass door that locks.
    Just my opinion

  • OBIEE 11g and In-memory options

    With all the data In-memory options, has anyone utilized any of these vendors with OBIEE?
    My question is for those who don't go the Exalytics route, as it seems with Oracle in order to utilize their Times Ten In-Memory option with OBIEE you have to purchase the Exalytics appliance.
    We had discussins with Terracotta and their BigMemory offering, however, they aren't aware of any customers using it with OBIEE as it offers a JDBC connection which the RPD can't utilize.
    Anyone have any experience or thoughts on this?

    Who said you must buy Exalytics in order to use TT with OBIEE? If you already have it, just create an RPD connection pools and off you go. You won't be able to use all the nice bits 'n pieces a full Exalytics sports, but where OBIEE is concerned, it's just a source like any other.

  • New Xserve in a tower configuration?

    We are a small publishing production company that has thousands of files that are currently living on 2 NAS boxes. These boxes are starting to have issues since they were never designed to be used as servers (which we are doing). This worked fine when there were only 2 employees working off the boxes. Now there are 4 employees cranking on them and we are starting to have production issues. We run both Macs and PCs and have decided to get a mac server since 90% of our work is done on the mac. I know nothing about mac servers and our contract IT guy is, of course, a windows junky and is proving to be of little help. I have been reading about the new XServer that is not yet available. I can't find anything about tower configurations, only rack mounts. Is this the only way the mac servers are available now? We have limited space. I know I can get an older server but I'd really prefer to stay away from buying hardware that is no longer in production.

    Stephanie Kuhns-
    Ya gotta love the battles with the windows junky. Maybe you can win one here.
    A lot of small businesses exist on so-called "Servers" cobbled together from what was cheap and available at the time. I know of a business still running on a couple of G4 towers and another one that is atill running on some fairly old Sun boxes. But I digress.
    You can run the XServer software on a number of different Apple platforms shown at the bottom of this page: http://www.apple.com/server/macosx/specs.html
    So basically the answer to whether or not you can run OSXServer on a tower is yes.
    This page is an excellent place to start digging for information: http://www.apple.com/support/macosxserver/
    The Xeon-based server should be out soon.

  • RAID 10 on new XServe 10.5

    Planning deployment of new XServe. Will be preparing 2-1TB disks for multiple RAID sets (0+1), using multiple partitions on each drive. What happens when/if one drive fails? Since a RAID 10 requires 2 RAID 0 sets and one RAID 1 set (or visa-versa as the documentation says), how will I handle a rebuild?

    RAID 10 with 2 drives? Why are you doing this? What do you expect to gain?
    RAID 0 gives you performance by spreading content across multiple disks.
    RAID 1 gives you redundancy by writing data to multiple drives.
    RAID 10 combines both, but only if you're using more drives.
    Performance of RAID 10 with two drives will be HORRIBLE. You will have to write all data 4 times - twice to each drive. Latency will be terrible and you won't have any redundancy at all - the only thing RAID 1 provides protection against is a failed drive - in this model, if you lose a drive you've lost all your data because it contains at least one component of the RAID 0 array.
    Rebuilding your array will be the least of your problems - there's no ability to recover from a failed disk, so you'll be re-installing from scratch.
    In all, I strongly urge you to NOT do this. Pick RAID 1 or RAID 0, but not RAID 10, at least not without more drives.

Maybe you are looking for
