I have an array that is made up of 2TB Dell branded Seagate Constellations that simply refuses to die or.... even degrade.
I have the opportunity to grab another handful of Dell branded Constellations for literally nothing, but they are a generation older.
Current drives - Constellation ES.1 (7200RPM, SAS 6G, 64MB Cache)
New/old drives - Constellation ES (7200RPM, SAS 6G, 16MB Cache)
Would you mix these drives within the same array ? an existing array ? (SAS2108 based HW RAID5)
Could it be as easy as setting 'Disk Cache Policy' to DISABLED in MR Storage Manager ?
Am I about to introduce problems to my 'array that refuses to die' ?
The current array is made up of 8 drives and I am looking to expand it to 12.
(still SAS2108 based HW RAID5...perhaps RAID6 with additional drives)
As always, thanks in advance,
Allan
