Parallel SCSI, Hardware RAID, SAS, Fibre Channel.  - What's included?

If I get the $2500 vanilla (nothing added) Mac Pro...
Do I get any of these?
Parallel SCSI, Hardware RAID, SAS, and/or Fibre Channel?
Just curious. I know what they do, but I'm just wondering if it's included with the Mac Pro with its price tag.

None are included.

  • Xserve, G5, Xserve RAID and fibre channel question

    hi guys,
    I have a Xserve conneted to Xserve RAID right now. Is it possible connect G5 to Xserve RAID thru fibre channel ? thanks

    >is it possible to do ?
    Not in the way you describe, no.
    The XServe RAID's 14 drives are connected to two separate controllers. Drives 1-7 are connected to the upper controller. Drives 8-14 are connected to the lower one.
    If your XServe is currently connected to the upper controller it's talking to drives 1-7.
    If you connect the G5 to the lower controller it will be talking to drives 8-14.
    Therefore you cannot use this setup to backup the data via the G5.
    At the very, very least you need a fiber channel switch so that both the XServe and the G5 can connect to the same controller. However, as Tod has already mentioned, it is tricky to get multiple machines talking to the same RAID drives while avoiding corruption (there's no concept of arbitration, or ways of preventing one machine from editing a file that's in use by the other machine).
    You have two basic options - one is to implement XSAN, which will handle the arbitration issue, the other is to configure the G5 to mount the RAID read-only. This should prevent the G5 from modifying a file while it's in use by the XServe (which may be sufficient for backup purposes), but you may still run into issues when the G5 tries to backup a file that's actively in use by the XServe.
    In all honesty, a better solution would either to get a SCSI card that works with the XServe and do it all there, or use file sharing between the XServe and the G5 and backup over the network - it'll be slower, but a lot more reliable.

  • Clarification on how to use Xserve Raid and Fibre Channel without xsan.

    First let me apologize for not responding earlier to your response, I tend to get busy and then forget to check back here.
    Tod, the answer to your question is No, only one computer is accessing the xserve raid files at any one time and that is via Fibre Channel. However I do have the xserve raids set up as share points via ethernet.
    Maybe I should turn that off and only access the files with the one computer that can connect via fibre channel.
    I never thought of that. I will try that while I await for your answer, thanks again.

    I have the following setup:
    Xserve: 2x2Ghz Dual Core Intel Xeon, 5Gb of Ram, Running 10.5.8 Leopard Server
    Xserve Raid with firmware version 1.5.1/1.51c on both controllers, and
    Qlogic Sanbox 5600
    Apple Fibre Channel Cards in Xserve, and Mac Pro Tower; Apple 2 Port 4Gbs Fibre Channel Card
    Mac Pro Tower-Quad Core Intel Xeon 2.8Ghz, 16Gb of Ram, Running Snow Leopard 10.6.4
    Here is the problem.
    The directory for the xserve raids keep getting corrup, and I use disc warrior to rebuild them. Is there a way to keep the directories from getting corrupt? I am a few pieces of equipment before I can build an Xsan as that is the ultimate goal, but until then, I just need to be able to have the raids funciton as storage without having to rebuild the directories all of the time.
    Anybody have any suggestions?

    Re: Xserve Raid Mounts, Corrupt Directory tired of rebuilding directory
    Posted: Jun 27, 2010 1:25 PM in response to: Todd Buhmiller
    Are multiple computers accessing the same data on the RAID at the same time?
    If so then NO. This is the source of your data corruption and I'm surprised if you were able to get all your data back every time if this is how you've been running your system. Each fibre channel assumes it has full and sole control of every volume it has mounted, no data arbitration is practiced and data corruption will occur if this assumption is wrong.
    The only way this set-up will work is to use partitions or LUN masks so the volumes are accessed by one computer at any time. As long as one computer relinquishes control before another mounts it you will dodge arbitration issues but this is a dangerous game. If you screw up and mount an already mounted volume - and there is no easy way to tell if a volume is mounted - corruption will then occur. Sharing data simultaneous at fibre speeds is what XSAN does and to do this you need it.

    Intel Xserve, G5 XServes, XRAID, Promise

    +The xserve raids will mount automatically to any computer that I connect the qlogic fc switch to+
    This is source of the corruption to your data. Any computer that attaches to a drive/partition via fibre channel assumes that it alone is in control of the drive and data corruption is inevitable.
    +Is that the issue, should I disconnect the xserve from the fc switch and leave it connected via ethernet?+
    Short answer: YES. The ethernet connections are fine because the server is controlling the file arbitration through the sharing protocol. Fibre channel connections assumes complete control over the partition and no arbitration of the file access is performed. It's like two people independently driving trying to drive the same car to different locations.
    Depending on your set-up it is possible for the two machines to see and use different parts of the Xserve RAID storage but they cannot access the same areas without SAN doing the arbitration.
    Hope that's clear,

    Virtual Fibre Channel had sense in pre-R2 times when there was no shared VHDX and you had to somehow provide fault tolerant shared storage to guest VM cluster (spawning iSCSI target on top of FC was slow and ugly). Now there\s no point in putting one into
    production so if you have issues just use shared VHDX. See:

    Shared VHDX is much more flexible and has better performance.

  • I-SCSI or Fibre Channel for SAP on ESX ?

    Hello,
    i have 4 ESXI Hosts with 2-6 vmware machines. Every machine contains a NW 2004s system (test, demo, education) with 8 GB ram and MaxDB database with 50-100 GB. Today the machines run with local Harddisk, but we plan to buy a SAN. I prefer a low cost fibre channel solution on basis of
    Infortrend EonStor S16F-R1840 (RAID-System) and Qlogic SANbox 5800 V (SAN Hardware), but our central it administrator wants a solution based on 10 Gb i-scsi.
    I read several blogs and articles, but im am really unsure which technology we should use.
    Greetings
    Heiko

    We have our entire VMware landscape running on iSCSI SAN's, including SAP, Exchange, File/Print services.  Before we went this direction we tested what our needs were to determine which option would best meet our needs.  We found that the iSCSI solution would more than cover our requirements.  Couple this with the fact that iSCSI uses copper, infastructure costs would also be lower.
    We are relatively a small shop, approx 200 users on 3 ESX hosts with 35 VM's, so the iSCSI option was a good fit for us.  I would recommend trying to find what your requirements are for performance on the SAN, this will help you determine which technology to go with.  In our case both cost and performance were in the favor of iSCSI and that is the direction we went and have had no problems.   Hope this helps.

  • Easiest solution for adding Fibre Channel Tape Backup to Xserve RAID setup

    I'm interested in getting a Fibre Channel LTO-3 tape library such as the Exabyte 221L for my Xserve RAID/Xserve G5 setup. I realize there are SCSI LTO-3 solutions that are less expensive than FC, but I'd prefer not to have to add a SCSI card to my Xserve, mainly because I'd have to pull the video card and run the server headless (horrors!). However, I understand that I must get a Fibre Channel switch to allow the LTO library, the Xserve, and the Xserve RAID to communicate... you can't just daisy chain FC devices. The least expensive switch I can find is the new QLogtic SANbox 3050 for about $1800. For my situation, in which these will be the only FC devices I'll probably ever use, does this switch sound appropriate? The specs on the switch can be found here: http://www.qlogic.com/products/sanbox/sanbox_3050.asp.
    Xserve RAID & Xserve G5   Mac OS X (10.4.5)  

    For simple environments like yours, it's trivially easy. You must plug everything in, and you're good to go... as simple as a network switch.
    Now if you start adding multiple hosts (i.e. plug in a second Xserve or G5), you need to be careful, because in the default configuration everything is "wide open," so every device can see every storage LUN. This would actually be problematic, as systems could (actually, would) corrupt each other's storage. When you get to this point, you'll need to look at either zoning the ports on the switch, or using LUN masking on the Xserve RAID to allocate specific pieces of storage to specific hosts.
    But for now, just get the switch, plug everything in, and you're off.
    BTW if you mark "answered" for me, versus for the thread overall, it helps me out a bit in this forum ranking system, whatever it is.
    Cheers.

  • 4 xserves, 1 xserve raid, 4 partitions, fibre channel - possible?

    Is it possible to connect 4 xserves to 1 xraid that has 2 partitions for each side of the controller to all connect together using a fibre channel switch?
    Thanks!
    Tony

    Hello Paul,
    LUN slices are all equal sized - ie you slice it into two, three or four slices but they will all be equally sized. You can't slice off 1/3 of a RAID side and the leave the other 2/3s alone. (I guess you could slice it into three and then RAID0 the other two slices back together but that seems too tricky to be a good idea.) The advantage is that each LUN has a logical "name" and you can hardwire your fibre card to see only that "name" and there is zero chance of conflicting control of a slice.
    If I understand you correctly you want to RAID 50 the entire RAID into a single big volume and the partition it up into smaller logical partitions. You will need to do the RAID0ing of the two sides before anything else because this will destroy the data that already exists on the RAID 5s. As long as you keep this in mind it is doable and you can then use fstab editing to control which Xserves load which volumes on start-up. Note that volume partitioning is not a set-up for a hostile environments because people will be able to do bad things if they are determined to do so - eg Using Disk Utility to force mount a volume they otherwise can't see and then play with it.
    My question is "Do you really need a single large volume?" Alot of people do RAID 50 the unit into a single image but unless you need more than 3TB volume sizes for some reason or for HD video capture I personally don't see the attraction. You take RAID 5 which is pretty close to bullet proof but then you build it into a RAID 0. The data on a RAID 0 is susceptible to loss from breaking the RAID while two separate RAID5s (especially with hot spare drives) is about as close as you can get to rock solid in computing. If you're going to then divide it up and redistribute it anyway I'm not sure if the merging of the sides is necessary.
    Only you can determine what you need but if you're not going to have a single >3TB volume I would go RAID5s on each side (7drives or 6+1spare ideally) and then either slice or partition up the volumes for the respective computers.

  • Fibre channel lights on Xserve RAID

    I have a G4 Xserve 1.33Ghz connected via Apple's Fibre channel card to a Xserve RAID. 3 drives installed, RAID 5 and a hot spare. The drives are installed in bays 1-4, but the fibre channel activity light is off on the left one, but active green for the right one. There are no drives in bays 8-14, the RAID controller is active.
    Surely the left light fibre channel light should be active, and the right one off.
    Any ideas, thanks

    Hmmm.
    I recall the lights on the RAID might be the reverse of what's expected? I'm not 100% certain here -- this may be normal behavior.
    Can you see the LUNs in Disk Utility? That's where you can usually check. You may also want to try rebooting once -- just in case the LIP message sent when the RAID came online was ignored.
    As for the RAID initializing... once you're above 2% or 3% or so it should be visible from the host... the default is to use RAID Now background initialization which means the volume is available for use (and safe to use -- data is protected), though a bit slower while the initialization completes. Initialization takes a long time -- ~30 hours or so.

  • Problem with fibre channel card and raid system after upgrading to 10.4.7

    Hello, I have a problem with our Xserve G4 DP. After the installation of 10.4.7 everything works fine exept our fibre channel card. This card is connected to a Hitachi Raid System which worked fine over a year. But after the update the volume was no longer mounted. I even reinstalled the server to 10.4.4 and no sign of our raid volume. Using the apple fibre channel utiltiy 2.0, I see that there is a connection - but still the raid volume is not mounted. When I restart the server the lights on the back of the card are shortly flickering and sending some packets to the raid system but that´s all. Has anybody an idea?

  • Xserve Raid will not mount - fibre channel link down

    I came back from being out of town and my Xserve is running, but will not mount on the G5 tower via fibre channel. It was powered off and up again and still nothing. Apple tech says to reset raid controllers, however, I have sensitive data on the drives and lots of video/FCP projects on there. It has just run out of warranty and now asked to pay $199 per incident to get any help. I will gladly take any help.
    Read the boards, ran Disk Utility and still did not show up.
    Also, told the fibre cables tend to "burn out" but have yet to spend money if this is not the problem.
    Thanks.

    Resetting the controllers is non-destructive. However, if you power-cycled the array, that should take care of it.
    told the fibre cables tend to "burn out"
    I've never experienced (or heard of this) myself, and have never had a problem on any of my arrays, some of which have been running for years with zero problems. Of course, environment (especially heat) could play a part, but it seems a little bit of a stretch to me.

  • Xserve RAID Fibre Channel Lights pegged until disk activity

    We are having some issues with an Xserve RAID connected to a G5 Xserve running 10.4.8 Server. The Fibre Channel lights on the front are constantly maxed out, but whenever the disk are active the lights die down only to peg again when activity stops. Needless to say, we are having SEVERE access speed issues. Any ideas?

    This can happen in a protected RAID set (i.e. RAID 5) if a single raid member drive pops offline and back on again, since the RAID set has to re-build itself from the parity data in that case.
    It also happens after creating a RAID 5 volume, as the creation usually takes a few days (assuming you used the 'RAID Now' option), and so you'll see the blue lights.
    It also makes sense that the blue light 'spiking' would drop when you do a read/write, as the initialization process has to pause to handle the disk activity.
    Are either of these the case?

I've been told I need the driver for the array, naturally there isn't a driver for Mac to be had, but there are drivers for solaris, Unix, and windows. The last expert said to use the Unix driver, but I don't know where to put it in the system.
    So I need help, Terminal commands to talk to the drive and revive it hopefully, or a system program that will do something similar. None of my diagnostic programs sees the array. The Card came with no software or instructions. Neither did the array. I haven't been able to find any hardware information about the drive from FuJitsu at all, it's too old for them to bother with anymore.

    Thanks
    Doc

    I have to go with William on this one - if it's shows up over fibre then it should be okay. Have you gotten the admin module to see the device over ether? I have a feeling that is you can get the software to see it you might be able to configure the device into something the computer could mount.
    The Promise that way - you can configure the device entire from the web interface and you don't need fibre communication working for any of the configuration of what RAID you want and which disks are attached with what set etc. Once the RAIDs are configured into volumes then the Xserve sees they exist and you can use Disk Utility to format them. If you don't need fibre communication I don't see how SCSI drivers would matter over ethernet. But maybe the box is a strange beast - odder things have been made.
    Barring that - can you attach the device to an older machine with the drivers and configure the device into raw volumes and then an HFS+ (or whatever you want) system? If you did that and then switched the box back to Xserve it should be able to pick up the configured volumes drivers or no.

  • Need docs that explain Fibre Channel setup, getting I/O error on 2540 SAN

    Sun T5220 Host running Solaris 10 5/09 as management host.
    Qlogic 5602 FC Switch
    Sun Storagetek 2540 - one controller tray with 9 300G SAS Hitachi drives. Firmware 7.35.x.
    Sun branded Qlogic QLE2462 HBAs - PCI express, dual port. 3 in the T5220. qlcxxxx drivers for the HBAs.
    Sun Common Array Manager software version 6.5.
    I am a long-time Oracle DBA who has the task of setting up a Fibre Channel SAN. I am not a Solaris sysadmin, but have installed and maintained large databases on Solaris boxes where I had access to a competent sysadmin. I am at a classified site and cannot bring out electronic files with logs, configuration info, etc. to upload. Connecting the T5220 is the 1st box of many. This is my first exposure to HBA's, Fibre Channel, and SAN, so everything I know about it I have read in a manual or from a post somewhere. I understand the big picture and I have the SAN configured with 2 storage pools each with 1 volume in them on RAID5 virtual disks. I can see the LUN 0 on the T5220 server when I do a luxadm probe and when I do a format. I formatted one of the volumes successfully. Now I attempt to issue:
    newfs /dev/rdsk/device_name_from_output_of_luxadm_probe
    I get an immediate I/O error. I could be doing something totally naive or have a larger problem - this is where I get lost and the documentation becomes less detailed.
    What would be great is if anyone knows of a detailed writeup that would match what I'm doing or a good off-the-shelf textbook that covers all of this or anything close. I continue to search for something to bridge my lack of knowledge in this area. I am unclear about the initiators and targets beyond the fundamental definitions. I have used the CAM 6.5 software to define the initiators that it discovered. I have mapped the Sun host into a host group also. I do not know what role the Qlogic 5602 Fibre Channel switch plays with respect to initiators and targets or if it has any role at all. Is it just a "pass through" and the ports on the 5602 do not have to be included? Maybe I don't have the SAN volume available in read/write. I find bits and pieces in blogs and forums, but nothing that puts it all together. I also find that many of the notes on the web are not accurate.
    This all may appear simplistic to someone who works with it a lot and if you know of an obvious reference I should be using, a link or reply would be greatly appreciated as I continue to Google for information.

    Thanks for the reply. I had previously read the CAM 6.5 manual and have all the SAN configuration and mappings. Yesterday I was back at the site and was able to place a UFS filesystem on the exposed SAN LUN which was 0. I've not seen any reference to LUN 0 being a placeholder for the 2540 setup and when I assigned it, I allowed the CAM 6.5 software to choose "Next Available" LUN and it chose 0. LUN 31 on the 2540 is the "Access" LUN that is assigned automatically - perhaps it is taking the place of what you describe as the LUN 0 placeholder.
    I was able to put a new UFS filesystem on LUN 0 (newfs), mount it, and copy data to it. The disk naming convention that Solaris shows for the SAN disks is pretty wild and I usually have to reference a Solaris book on the standard scsi disk name formats. My question/confusion at the moment is that I have 3 Sun branded Qlogic HBA's in the Sun T5220 server - QLE2462 (dual port) with one port on two of the HBAs cabled to the Qlogic 5602 FC switch which is cabled to the A and B controller of the SAN 2540 - there are only 2 cables coming out of the 5220; the 3rd HBA (for future use) has no cables to it. Both ports show up as active and connected on the server down to the SAN and the CAM 6.5 software automatically identified both initiators (ports) on the Sun 5220 when I mapped them. I had previously mapped them to the Sun host, mapped the host to a host_group, virtual disks to volumes, volumes to....etc.; and was able to put data on the exposed volume named dev_vol1 which is a RAID5 virtual disk on the SAN.
    When I use the format command on Solaris, it shows two disks and I assumed this represented the two ports from the same host 5220. I was able to put a label on one of these disks (dev_vol1), format it, and put data on it as noted above. When I select the other disk in the format menu, it is not formatted, won't allow me to put a label on it (I/O error) and I can go no further from there. The CAM 6.5 docs stop after they get you through the mapping and getting a LUN exposed. I continue on the in a Solaris-centric mindset and try to do the normal label, format, newfs, mount routine and it works for the one "disk" that format finds but not for the other. The information from the format info on both the disks shows them as 1.09 TB and that is the only volume mapped right now from the SAN so I know it is the same SAN volume. It does not make sense that I would label it and format it again anyway, but is this what I am supposed to see - two disks (because of 2 ports?) and the ability to access it through one. I found out by trial an error that I could label, format, and access the one. I did not do it from knowledge or looking at the information presented....I just guessed through it.
    I have not "bound" the 2 or HBAs in any way and that is on my list as next because I want to do multipathing and failover - just starting to read that so I may be using the wrong language. But I am wondering before I go on to that, if I am leaving something undone in the configuration that is going to hamper my success in the multipathing - since I cannot do anything with the 2nd "disk" that has been exposed to Solaris from the SAN. I thought, after I labeled, formatted and put a filesystem on the one "disk" I can write to that the other "disk" that shows up would just be another path to the same data via a 2nd initiator. Just writing that does not sound right, but I am trying to convey my thoughts as to what I logically expected to see. Maybe the question should be why am I seeing that 2nd "disk" in a Solaris format listing at all? I have not rebooted any time during this process also and can easily do that and will today.
