  1. SLC's come at a premium, ~$3500 for 8 x X25-E SSD + RAID card. If I had to do it over again I'd have bought a couple of big Intel MLC SSD's and used RAID-0 on the motherboard w/out trim. 1-1.6gbytes/sec is quite nice but IMO the cost is not justified unless you REALLY need the speed, also w/this raid card it adds a good 30-60 seconds to each boot.

    3ware 9560 not recognizing sizes correctly

    Hi, Can you elaborate on this? What OS was used? Was the system actively accessing all of these files at once? (I assume no BBU also?)
  3. I got rid of mine and went Hitachi, no problems since.
  4. Hi, I have both types, as long as you have good airflow you should be fine either way: 5K3000: Device Model: Hitachi HDS5C3020ALA632 194 Temperature_Celsius 30c 7K3000: Model Family: Hitachi Deskstar 7K3000 194 Temperature_Celsius 33c
  5. Any reason not to go with 5K3000 or 7K3000 Hitachi 3TBs? I used to use WD RE3s (1TB) and the price of the RE4s when they came out was a bit high. I tried the Hitachis and they worked great. Using them on a 3ware 9750-24i4e.

    Which SSD? Please enlighten me.

    1. Would you recommend the Intel or the Crucial? > Intel. 2. Since i'm dealing with a bunch of relatively small files, random IO will be important for me. (please correct me if i'm wrong). It seems the Intel will be more suited for this job? Please confirm / deny. Yes, generally Intel is better for random I/O, although less so with the 510 series. 3. The Crucial 128gb SSD is slower than the 256gb? If so, by how much? About 1/2 for write speed. 4. And finally, price. When do you guys think these guys are going to drop in price? Should I wait? If so, how long? The Intel SSD 510 is out, I'd go with two of those, they will work nicely (6 Gbps SSD) with your 6Gbps controller
  7. Found it (not on LSI's site though): Following post stolen from: http://www.tek-tips.com/viewthread.cfm?qid=1640298&page=1 Link to the above mentioned firmware: http://www.lsi.com/DistributionSystem/User/AssetMgr.aspx?asset=56123 Readme.txt for Beta firmware for LSI 3ware 9650SE and 9690SA RAID controllers v1.2 February 2011 Firmware version 4.10.00.021 Includes changes from previous beta version 4.10.00.016, 4.10.00.019, and 4.10.00.020. prom0006.img is for the 9650SE prom0008.img is for the 9690SA See LSI 3ware KB article 10058 http://kb.lsi.com/KnowledgebaseArticle10058.aspx for instructions on how to flash upgrade the controller. Summary of changes from 4.10.00.016 release (which are also included in this 4.10.00.021 release): SCR 2196: Unexpected controller soft resets Fixed an issue with regards to deferral of write and read commands to help eliminate unexpected soft resets.
  8. Do you have a link to .21?

    Hitachi's just work =)

  11. Hi, I see a lot of these: ErrorCode: 0x291, ErrorDisp: 0x4 Target type = 7, devId = 0x6 cdb ==> b7 08 00 00 00 00 00 00 00 08 E=0291 T=09:18:44 P=6h: Recovered Error, no retries Scsi Cdb ==> b7 08 00 00 00 00 00 00 00 08 Scsi Sense Data : 70 00 01 00 00 00 00 0a 00 00 00 00 1C 00 01 01 00 ca ErrorCode: 0x291, ErrorDisp: 0x4 Target type = 7, devId = 0x7 cdb ==> b7 08 00 00 00 00 00 00 00 08 E=0291 T=09:18:44 P=7h: Recovered Error, no retries Scsi Cdb ==> b7 08 00 00 00 00 00 00 00 08 Scsi Sense Data : 70 00 01 00 00 00 00 0a 00 00 00 00 1C 00 01 01 00 ca I don't recall seeing these on my controllers, you may want to open a case with 3ware/LSI to check on this and your problem in general. I ran that (and continue) to run that Beta firmware and I think I was only able to make it occur/reproduce it once and then it never happened again (I also turned off CPUFREQ/etc) do you use cpu frequency scaling? lsmod output?
  12. Hi, I recommend two things: 1. Upgrade to the latest beta firmware for your card: http://www.lsi.com/channel/products/raid_controllers/3ware_9690sa4i/index.html Name: 9650SE_9690SA_firmware_beta_fw_4.10.00.019.zip Changelog: SCR FIRM03219 Pchip reset interrupt not handled SCR FIRM03220 Put parity segment to free state completely when deallocate unused parity segment 2. Turn off 'cpufreq' / do NOT load this module if you are running it (disable any turbo boost if used) -- Can you also show /c0 show diag?
  13. What motherboard/CPU? Also what firmware of the card are you running? tw_cli /c0 show all

    sas h/d set up help

    You should buy a SAS RAID controller or HBA you can boot from (probably not worth the cost, an SSD is probably cheaper) and much faster.

    WD Black 2TB, WD2002FAEX vs WD2001FASS.

    WD2001FASS = original caviar black 3gbps sata WD2002FAEX = new caviar black 6gbps sata aside from that there may be other diff but thats the main one i think
