From: markm75 on 22 Aug 2008 11:40 -------------------------------------------------------------------------------- For our 40 user environment, with 3 physical servers and about 20 virtual servers (which run SQL on a few virtual boxes, about 13 instances of sql itself), 2007 exchange on the physical host.. we were looking to go SAN from here on out.. We have 2TB of data usage, with about 700GB per year added (by the end of this year, we'll be around 2.8TB). Currently we have 6TB of total space available across the 3 servers. I was thinking a SAS solution was the best bet, rather than sata and found a few options. Here are some of my notes next to each, anyone have any thoughts here? I'm thinking iSCSI is much cheaper and a better choice, but the HP requires their brand of drives and they dont offer 1TB SAS at this point (thought the Seagate 1TB drive is actually 7200rpm, not 15K and dual ported): http://h71016.www7.hp.com/dstore/Mid...&ci_sku=AJ927A HP MSA 2012I AJ927A $7546 SAN barebones , 2U, 12 bays, expandable to 48TB (48 drives) dual controller, iSCSI interface **free driver from microsoft (dont need accelerator license). More robust controllers.. more cache (1GB per controller cache). 3 years warranty (next day support). CANNOT use 3rd party party drives here! (450GB by HP in SAS just coming out, dual ported 15k sas. *thinking go with 1TB sata for one LUN (say 5 of them raid 6), the rest SAS in time. http://www.provantage.com/promise-vte610fd~7PROM17H.htm TB Promise Vtrak VTE610FD 3U 16slot, 3 year warranty, dual 4Gb Fibre channel, raid6, $6632 SAS/SATA (and simultaneous too!) ($9168 with 8TB of physical drives ANY brand, not counting fibre hardware) One external SAS 3Gb/s 4-port for JBOD expansion (can connect multiple chassis together) must add on desired harddrives (any brand); (switches: need 4Gb fibre switches 8 ports; pcie $900, host bus adapter fibre channel about $800 per unit) : $3300 in fibre hardware overall at least; Thanks in advance

If SATA is good enough, this opens up the field a bit. To me, the downside of going with a unit requiring their own manufacturer drives is cost.. whereas with the other ones that are open, would actually have the downside of having to deal with 3rd party drive support teams to get a drive sent out. I think there was another version of the Promise unit, which was Sata only and iscsi, though honestly, i'd rather have the option of going either sas/sata down the road.. Any thoughts on fiber? Seems to costly to me.. It did seem like the controller cards in the HP were much more robust too. I wish i had a few more models to pick from that did both sata and sas and were iscsi (any brand drives)... |
