    First look: Supermicro F617H6-FTL+ Ultra high density storage/cluster

    New Infiniband cables are in: They were a bit more expensive ($90/each), but note the ribbon looking IB cables on the left...these are from 3M and are *significantly* easier to install and have a much more liberal max turn radius that typical round IB cables. 5 of 8 nodes now up: Cluster...

    First look: Supermicro F617H6-FTL+ Ultra high density storage/cluster

    They say I got the first two of these from the factory: 48TB *and* 12 cores PER 1U! X4 per 4U chassis gives you almost ~200TB and 96 (hyperthreaded) cores. Some initial comments: * Amazing density...amazing price for what you get * Great power efficiency...E2600 CPUS *and*...

    1.5 Petabytes: Swiftstack In Pictures

    What hardware platform are you using for your cluster? Supermicro recently announced a sweet box for Hadoop: http://www.supermicro.com/products/system/4U/F617/SYS-F617H6-FT_.cfm (you actually want the other chassis that has the LSI 2308 (non-raid) HBA ... unfortunately there's not a...

    Supermicro: 6047r-e1r72l 72 drives in 4U

    Wow..somehow I missed this until now: http://www.supermicro.com/products/system/4u/6047/ssg-6047r-e1r72l.cfm 72 3.5" drives in 4U PLUS room for a main board! Hitachi 4TB is a supported drive, so 288TB in 4U...amazing. I can only imagine the noise the fans on this thing make...crazy.

    Building an Array with 4TB Drives..

    The Hitachi 4TB *7200* RPM drives are $199 this week at Frys (in store only). Unfortunately, I've been banned so no drives for me.

    Does this drive (controller?) exist?

    I don't think this is what the card you posted is all about, but on a similar topic happened to hit on stuff discussing new 'SCSI over PCI-e' standards which look REAL interesting: http://www.snia.org/forums/sssi/knowledge/standards and...

    ZFS debate: SMB/CIFS vs. iSCSI

    Let me expand on what Gea said with regard to effective ZFS snapshot differences. IMO one of the most powerful features of ZFS is the ability to not only take a snapshot, but also **to access the prior state of any file in any snapshot**. For example here is one of my zvols, I...

    Solaris Boot hang after ZFS drive failure

    Have had this happen a bunch of times over the last couple of years.: A drive fails in a storage pool (NOT rpool)...ZFS automatically resilvers to the hot-spare no problem and pool returns to normal state...however, if you leave the failed drive physically connected to the system *and* try to...

    ZFS Hardware for Petabyte and larger

    Here's the MB I was thinking of...11! Pci-e 3.0 slots...crazy. http://www.supermicro.com/products/motherboard/Xeon/C600/X9DRX_-F.cfm

    ZFS Hardware for Petabyte and larger

    I would not go with a 4U server chassis...go with a 2U that has bunches of 2.5" drive slots...use those drive slots for OS, ZIL and/or L2ARC drives NOT your actual storage drives. For 1PB you'd need about 250 4TB drives...to achieve this use SIX Supermicro SC847(E16)-JBOD enclosures...they...

    need advice with 16 TB of data

    Ditto! I've lost data countless times with hardware RAID due to how poorly it (Adaptec) handled drive failures and replacement. I vowed never again. I have 4 ZFS servers, Solaris 10, FreeBSD9, OI151, and even Solaris 11...over 100TB of data and in 3 years have lost a single byte. More...

    IBM/LSI 9202-16e - reflashing?

    I can't even figure out where this product is on IBMs web site..they *do* have several other 16 port LSI cards listed, but NOT that 9202-16e ... are at least as far as I can tell. Anyone know what IBM's product name/numbers are. I google for the text names that show up in LSIutil (e.g. SAS...
