SSD for FreeBSD NAS device
Hello, I have just acquired an Intel R2312GZ4GC4 which I have equipped with a Adaptec RAID 51245 and 6 WD red disks of 3To - It'll come with 32Gb of Kingston ECC RAM. I am planing to use It as a backup device on a second hosting facility to backup couple of critical servers of mine. Item: Intel(R) Server System R2312GZ4GC4 Intel(R) Server System: integrated in a 2U chassis supporting 12x3.5* Hot-swap drives, 24 DIMMs, 2 750W Redundant Power Supplies, enterprise class IO, Intel(R) Remote Management Module 4 (AXXRMM4R) Integrated Intel(R) Server System with (1) Intel(R) Server Board S2600GZ4 in 2U chassis, (1) airduct, (1) Control panel on rack handle, Support for 2x SSD mounting on airduct, (12) 3.5†Hot Swap Drive Carriers with (1) Hot Swap Backplane, (3) SFF8087 to SFF8087 cables, (2) CPU heatsinks, Redundant and hotswap cooling fans, (2) risers with 3 x8 slots (2xFHFL 1xFHHL), (2) 750W AC Power Supply, Intel(R) Remote Management Module 4, (1 Set) Value rails Qty: 1 I will use ZFS as file system for both the root drive (SSD ?) - and the Adaptec RAID / JBOD controller (RAIDZ2 probably). I wanted to know what were your experiences on choosing an SSD HD as master boot device / root FS ? Do you think I should go for a redundant SSD drives (RAID 1) or does this offers limited interest in such config ? I have been reading comments about failure / problems here and there, but comments are not so fresh (one year is very old in SSD). So I wanted to have fresh infos and updates on your experiences with SSD on such mid size system.

For any critical server, don't think of RAID as an option, think of it as a requirement. -- Dan Nelson dnel...@allantgroup.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Do you think I should go for a redundant SSD drives (RAID 1) or does this offers limited interest in such config ? The advantage of SSD drives is their speed, in a ZFS config they can help most in two ways, as cache devices to speed up disk access or as log devices to increase reliability. Personally for a backup server I would use the two SSD drives as a mirrored log device for the ZFS pool. Reliability over performance. Having said that if you haven't got them I wouldn't get them. For a busy fileserver in the office you want the extra performance. As an offsite backup server the time saved in performance is only going to impact a few times a day and will be outweighed by the network speed. The cost of the SSD drives could add more drives to increase space or redundancy - RAIDZ3 ? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
