Red Hat and HP Establish Linux Storage Lab 82

Posted by CmdrTaco from the your-put-your-bits-in-there dept.
Rob writes "Linux distributor Red Hat has teamed up with Hewlett-Packard to create a new performance test lab to help customers deploy enterprise storage across Linux environments. The lab will focus on performance and integration testing in order to produce best practices and solutions guides, the companies said, and will also enable customers to preview new technological developments."

        They do that for simple reasons such as:

      Not to be confused with the Google File System [rochester.edu]. A lot of people confuse them (same TLA), so it's important that sysadmins are clear that they are very different. If you install G[lobal]FS, you're getting something that has different goals in distributing the data than those of the Google servers. Google's FS has only a modicum of documentation, and no public implementation available. If you want to replicate GoogleFS, you'll have to guess as to the parts that their documentation doesn't cover.

      Now back to your regularly scheduled program. :-)

      I don't see how GFS can scale as well as something like OpenAFS [openafs.org]. With AFS, you get an entire infrastructure. I wish more people would be investing time and effort into improving filesystems like AFS, where all systems can share a common namespace without requiring the availability of a SAN. The two have slightly different uses, but it'd still be nice to see more force behind AFS now that it is opensourced.

        IIRC AFS only provides for a single system to be the writer to the whole distributed filesystem (though it does allow replicants so even if the main server dies the files are still available for read).

        GFS allows every node to read and write simultaneously so each system can get full bandwidth out of the storage unit.

        They're rather different beasts, solving different problems.

      • No, all computers share a "drive" and GFS makes sure they don't step on eachother's toes. Usually that "drive" is a largish storage device with a lot of harddisks, though.
        • What he said. GFS is similar (in concept, anyway, I haven't looked at GFS's innards) to OCFS (Oracle Cluster Filesystem). It lets multiple servers shared the same "drive". (Typically a high end SAN, but OCFS -- and I'm presuming GFS -- will work with multiple computers plugged into the same single FireWire drive.)
          • Correct.
            (Note that GFS predates OCFS, GFS grew out of the University of Minnesota and has a long history there)

            In order to use GFS your nodes need some form of "shared blockspace (disk)". Traditionally this has been Fibre Channel Storage, but there is nothing in GFS that prevents using a shared FireWire, iSCSI or any other shared blockspace. The problem often seen here is that even if a "disk" can be shared it does not always behave "nicely" in such a setup. Lower-end devices are often not designed to perfo

Red Hat recently announced that GFS is now supported by Oracle for use with Real Application Cluster database configurations, and has been certified for use with EMC's Clariion networked storage systems, and Celerra iSCSI network attached storage systems, as well as Network Appliance's SAN interfaces BTW HP has been offering RAC on RHEL already for a long time now.

    to announce a Linux partnership?

    It was almost a given that HP would team up with some major Linux distro, given that they have a fair sized share of the corporate market. I'd open my eyes a little more if Dell or another primarily HSB (Home and Small Business) OEM were to start to offer Linux systems.

    Of course, it'd also be nice if some of those manufacturers would also add Linux support for their peripheral products. There's so few good drivers for printers/scanners/all-in-ones, especially from HP (which I do tech support for), and tbh I don't have the coding skills to build my own. It's probably a big reason that Linux use is still relatively light on the HSB side.

    Being seasoned in Linux enterprise deployments, I've had more than my share of frustration with some of HP's own storage appliances. Their entry-level storage appliances, the MSA series (which IIRC, they inherited from Compaq), seem to be pretty ok, but they're no good when you start growing to the point when more than several machines need to attach to the SAN. The VA series of high-end storage appliances are in contrast the very devil to deal with. I remember the problems a client of ours was having with these monsters when they were using it for Oracle 9i RAC. Their RAID management started having problems once the disks started filling up to more than 75% capacity, and HP never was able to give us a satisfactory solution, except to replace the damn storage array with something bigger and much more expensive. And so overtures from the likes of EMC began to reach much more receptive ears...

    I certainly hope this helps with the engineering of HP's storage appliance line, and they can fix some of the brain damage that some of them have.

    • Only thing good out of HP's storage is their ultra high end arrays which is practically HDS's lightning san arrays rebranded into HP XP series. MSA and VA is not remotely comparable to what the rest of the storage industry has to offer.
