    Strange boot loop - Supermicro/Intel

    Yeah everything was A-OK after I built it, ran solid for a year. Then I abandoned it for about 3 months. I'll check into the LSI firmware as delivered by Supermicro.

    Strange boot loop - Supermicro/Intel

    Hey Everybody, I have a rather vanilla Supermicro dual Xeon system with an integrated LSI 2208 card, two Hitachi 10k SAS drives in a raid1 array. For about a year, Windows 2012 R2 was installed and the system was used for SAS analysis stuff. Rather boring. A few months of non-use go by...

    ZFS L2ARC sizing

    How would this play out with the default 128k record size? Where did you get your values? Thanks, AUPhil

    ZFS L2ARC sizing

    I can't imagine this being a hard and fast rule. For a specific use case it may be too much, as in "you spent too much money on that ram".

    ZFS L2ARC sizing

    Thanks, we have a ZeusRAM mirror (8GB) for write logging already. My concern was not eating up too much ARC (memory) used for L2ARC addressing. I was wondering what the sweet spot of L2ARC sizing would be in GB.

    ZFS L2ARC sizing

    Configuring Solaris 11 with Dual SAS HBAs

    Well the disk claims to be dual ported: http://www.amazon.com/HGST-Ultrastar-3-5-Inch-Enterprise-HUS723030ALS640/dp/B0082D58L8#productDescription It's a very vanilla setup. SuperMicro + LSI + Hitachi UltraStar SAS drives. Dual pathing is not required for my project. However if it shows up...

    Configuring Solaris 11 with Dual SAS HBAs

    Funny how writing a question can make you think about it. Perhaps Solaris 11.1 uses the disks' WWN IDs to uniquely identify SAS disks with multiple paths between the head node and the disk? Thanks, AUPhil

    Configuring Solaris 11 with Dual SAS HBAs

    Hello Everybody, I'm building a backup system using ZFS on Solaris 11.1 (we have a site license). My head node is a SuperMicro 6037R-E1R16N. I want to cascade to 2x SuperMicro 847E26-RJBOD1 jbod boxes. I have 2x LSI SAS-9207-8e cards on hand (not sure I will need both). My question is...

    ZFS Snapshot Deletion Question

    Guys, Just wondering, if I recursively delete all snapshots in a ZFS zpool, is that operation analogous to deleting virtual machine snapshots in VMware ESXi ? Meaning, you are merely deleting all intervening checkpoints and "flattening" the object? Thanks, AUPhil

    Has OCZ abandoned the Deneva 2 R line?

    Has anyone had trouble ordering Deneva 2 R SLC drives? http://www.oczenterprise.com/ssd-products/deneva-2-r-sata-6g-2.5-slc.html I cannot find them anywhere. I've had four orders cancelled because "We've received your order but unfortunately OCZ is out of stock on the OCZ 50GB...
