  • Okay, so at a brief glance it's looking like next-gen primary disk storage. I didn't see any mention of which RAID it is (although I'm thinking they're probably going RAID 10??? Maybe 6?). What's cool though (at least by my opinion) is that it's going to cut down on SAN errors through self-diagnosis. Interesting, will have to check through the white paper.

      not only self-diagnosis, but onboard disk remanufacturing ffs

      100 or so engineers involved in the project have replicated Seagate's own processes for drive telemetry monitoring and error detection -- and drive re-manufacturing -- in firmware on the Linux-based ISE. ISE automatically performs preventive and remedial processes. It can reset disks, power cycle disks, implement head-sparing operations, recalibrate and optimize servos and heads, perform reformats on operating drives, and rewrite entire media surfaces if needed. Everything that Seagate would do if you returned a drive for service.

      • What is "Failing only one surface"

        A hard drive can fail in many ways: sector, track, platter, head. ISE can fail just the one surface -- say, a platter -- and keep writing to the remaining device. The broken platter is removed from service while the remaining disk storage continues to be used until end of life.

        This is all done automatically and transparently. What they are trying to eliminate is the time it takes for someone to physically swap out a disk.

        Disk drives are made up of surfaces on platters. Generally, disk drives have multiple platters, with each platter having a top and bottom surface.

        Currently, in a disk if one chunk of a surface has a problem, the whole disk is bad. The disk has no way to communicate which part has died.
        Xiotech's hooks into the firmware allow it to write around bad areas on the surface of a disk, and when a portion of a surface does fail it only has to rebuild that portion, rather than the entire disk drive.

A lay explanation: think of your normal network and how it's connected. A SAN network (usually composed of fibre channel or SCSI connections) underlays that existing standard network and moves all the data you want to back up to disk or tape, without eating up the bandwidth you have on your normal network.

        Just to clarify, SANs generally aren't used primarily for backups - they're just used for server storage to have a centralized and more thoroughly redundant setup than local disks (i.e. put your 40TB document repository on the SAN and connect it over fiber to the server, or have your server boot off the SAN instead of local disks, etc). They're treated like local disks by the OS, but are in a different location connected via fiber or nowadays via iscsi.

        While you can sometimes do some neat tricks with backups and a good SAN infrastructure, it's by no means its primary purpose in life.

        You could use it for that, but thats not the main use.
        It *is* a network like your ethernet network (with switches, adaptors, etc), but usually its a FC (fibre channel) rather than ethernet. You use a SAN to put your servers disks in another box to the server.
        But why would I do that? heat, consolidation, redundancy.
        A typical setup is to have a few 1u or 2u (rack heights are measured in u, which iirc is about 2") servers attached to a 3u storage controller.
        This is a box with lots (typically 14 in a 3u box) of drives. There will be a small computer controller in there too as well as some raid chips.
        Typically in a 14 drive box you might configure it as a pair of 5+1 raid 5 arrays and a couple of hot spares (5+1 means 5 drives of data and one parity drive). Effectively your 6 drives appear as one with 5x the capacity of 1 of the component drives. You can survive the loss of one drive without losing data. If you do have a drive go offline, the controller should transparantly start rebuilding the failed disk on one of the hot spares (and presumably raise a note via email or snmp that it needs a new disk).
        The controller is then configured to present these arrays (called volumes in storage speak) to specific servers (called hosts).
        The host will see each array as a single drive (/dev/sdX) that it uses as per normal, oblivious to the fact that its in a different box.
        Now to revisit the why we do this:
        1. heat - by putting all the hot bits (drives) together we can concentrate where the cooling goes
        2. reliability - any server using the above setup can have a disk fail and it simply won't notice. With the hot spare setup, you can potentially lose several drives between maintainance (as long as they don't happen at once).
        3. cost - you can buy bigger drives, then partition your array into smaller volumes (just like you partition your desktop machine's drive) and give different chunks to different hosts, reducing per GB cost (which when you are potentially talking about tera and peta bytes worth of disk space is rather important).
        as for what these guys are up to, I've not had a chance to look yet. I might post back.
        • You forgot the most important bit speed. SAN's are orders of magnitude faster than most internal hardware raid. Think many GB's of battery backed up write cache.

        Ok, Have now rtfa'd. Basically, they have built a shiny controller/enclosure (the enclosure is the frame that contains the drives and the controller the circuit that interfaces, although to be confusing controllers often are built into enclosures (especially on the lower end) and still referred to as a controller)
        This controller is a sealed unit (read: better heat/vibration support, but not a user servicable component) with excess disks inside (multiple hot-spares, so even if several drives fail over time it keeps going), combined with the knowledge san techs across the globe know: most errors are transient, and if you pull the disk out and stick it back in, it will probably work again. They have just built a controller that does that for you automatically. Definately on the evolution rather than revolution side of things, and I have to admit I fail to see the disruption here, although I could well be missing something ( the whitepaper is somewhat light on details shall we say ).

          Heat is key here. Have you ever stood next to a petabyte of storage? Or even a few terabytes? Most Sans kick off a lot of heat from all those disks. When looking San to Hvac, 1 TB to 1 ton is typical.

          Xiotech's ISE mounts the disks on a very large aluminum alloy heat sink. The heat is wicked away from the drives. This makes for better heat dissipation and less heat on the disks, thus improving cooling and extending lifespan.

            When you need more space, you add more drives and the system manages the striping, re-striping as necessary for optimum throughput and maximum redundancy, rebuilding failed drives as necessary.

      The second article describes this very well. One big extra is that this system can perform all of the standard drive-repair operations that typically only OEMs can. This helps to keep you from replacing drives that aren't bad, but had a hiccup.

      It's also not just two drives in an ISE, but more like 10-20 (3.5" and 2.5" respectively) with a bunch of Linux software to give each ISE a pretty robust feature-set in itself. Then they also up the block size to 520 bytes, leaving space for data validity checks in order to keep the silent corruption problem from sneaking into the system.

      In the end, it's probably not wholly revolutionary. It does seem like an evolutionary jump though; with great performance, great feature set, and a very well thought out system that brings new technology and ideas to bear.

      If (big IF), the units eat drives (as in kill them in a non-repairable way), yeah, it's a bold and stupid move.

      If (another big IF) the unit keeps soft-failed drives (which weren't really bad to begin with) in play longer because it can recover them from *burps* in the system, then it's entirely possible that the unit could potentially be a money-saver.

      You don't need to replace a module, because it doesn't break. See the failure rates/service event numbers from their presentations.

      People are so used to disks failing. Disks shouldn't fail as often as they do, and most of the time they don't fail at all - the storage controller is at fault because the drive and the controller have such a limited language (SCSI) to talk to each other with. ISEs do away with this limitation.

        Thing is, I spent the last couple years playing this game. I started with a dozen 36-gig scsi disks that had bad sectors on them. I did thorough tests abandoned the whole gigabyte where the bad sectors were found and software-raid-5'd partitions from multiple drives, skipping those bad parts.

        Guess what? It didn't work out. The bad zones spread and they spread faster than the the raid software could detect the new failure and rebuild onto the spare.

        I quite enjoyed the experiment, but these were on my home servers. I wouldn't dream of doing this in a production environment. When the raid controller kicks the drive for -any- reason, it's back to the manufacturer for warranty replacement. The data is far to valuable to play games with it.

          You'd detect the failure the instant you tried to read the sector, and could speed up this process by using idle time to check sectors for corruption (checksums help). With double parity, you'd have to have the same stripe go bad on three different disks to lose data, and I have trouble believing that the failures would spread that fast.

          I mean, I still wouldn't trust it in a production environment, as you said, I just wonder how a more dynamic system (RAID-Z, for example) would handle the same scenario. At
