'Standard Mini-SAS Connectors (SFF-8087 and SFF-8088 )'ģ & 4 (combined) It appears that the PERC 6 may not support HDDs larger than 2 TB. *** This appears to be correct per the PERC H700 Technical Guide O Optimized for superior IOPS of SSDs over HDDsĪny answers and/or additional advise would be greatly appreciated!!! O Performance boost of up to 2X IOPS performance Can I set these differently per VD, as I would obviously want WB Cache & RA on the SATA LUN, but not on the SSD LUN correct? Should this be done while I'm still on the old PERC 6i Controller due to all HDDs being forced to operate at a common 3 Gbps, or will it not matter if I do this off the new H700 even though the old 1TBs will operate at 3 Gbps and the new 2 TB Drives will operate at 6 Gbps?Ĥ) I should then be able to install the H700 and import the Foreign Disk Config of the old VDs into the new H700, and then use MegaRAID Storage Manager to Expand the VD?Ĥ.1) The H700 should have no problem seeing and working with the 3 TB Seagate HDDs right?ĥ) To get the fastest speed and best throughput with the SSDs I will need to enable 'Cut-through IO (CTIO)' by setting the Cache to Write 'Through' (NOT Write Back) and turning off 'Read Ahead' on the H700? I plan to simply Image the C: Drives (SAS 146s to 240 SSDs, not too concerned here) and expand the D: Drives (1 TB SATAs to 2 TB SATAs) if possible.ġ) I need the following Cable to connect the Disks to the new H700 Controller?Ģ) I will need to mask Pins 5 & 6 on top side of H700 with Fingernail Polish, just like I had to with my PERC 6i to fix the SMBus issue?ģ) I should be able to fail each of the 4 x 1 TB HDDs at a time and replace them with the new 2 TB HDDs letting the Controller rebuild the array each time correct?
