We have a Dell T320 with a S110 software RAID with 7200RPM SATA drives. The RAID level is 10 with four drives. I underestimated the demand on the disk, and it is now a major bottleneck of the system.

Is it possible to replace the drives with SSDs?

If so, can they be hot-swapped? What is the recommended upgrade path?

  • I've seen a similar question, but it was regarding SAS to SATA drives. In this case, both the existing and new drives would be SATA.

Try replace S110 to other high end raid card, such as H700/H710. This raid card have a feature called cachecade which will boost performance dramatically with SSD. try to google "PERC H700 cachecade" to get more details.

H700 http://www.amazon.com/gp/product/B013X1JXBE?m=A4J4F1MELOD6E&qid=1455865139&ref_=sr_1_11&refinements=p_4%3ADell&s=merchant-items&sr=1-11

if no backplane for hotplug, you'll need a conversion cable http://www.amazon.com/gp/product/B012BPLYJC/ref=pd_lpo_sbs_dp_ss_2?pf_rd_p=1944687542&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B005JZDUHQ&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1MVJ61GDYQQRB7DACP8M

But one thing that I'm not sure is, whether H700 can import S110 raid config or not, make sure make a full backup before any move.

Good luck

  • One more thing. Dell raid card is picky, only DELL certified SSD work with DELL raid card, and Samsung 850 EVO is one of them. Feb 19 '16 at 8:21
  • What about replacing the drives with SSDs? They are currently Dell 7200 SATA. Do I just need to restore from a backup, or can I hot swap?

  • If your configuration is 4x500G SATA RAID-10, may try to buy 4x500G SSD and replace drive one by one, for example replace drive-1, wait until RAID drive synchronized and then replace drive-2...etc. SSD is cheap, only if size smaller than 1T, if 1T+ SSD is another story. By default, S110 support hotplug and if your server have hotplug tray, then you can hot swap the drives. Feb 24 '16 at 8:53
  • One more thing, S110 only have 3Gbps per connection and possibly a bottle neck, thats why I recommend to change to H700, which provides 6Gbps connection. Feb 25 '16 at 6:55
  • Thanks, this has been helpful. I'd really like to see some more info on replacing RAID drives with SSD hot-plug. I'm not confident in it enough to do it myself yet. And they are 1TB drives, but it might still be worth it for this server that runs everything for a small business.
