I would like to get your feedback about a controversial situation I found myself in some days ago. I was tasked to use a HP Proliant G6 for development purposes with 2 new (< 2 months, never used before) non-HP SSDs used in RAID1 configuration. They are being used for intensive development-oriented tasks (about 500GB written per day); there are also regular HDDs in RAID5, but we will discuss the RAID1 array here.
- Samsung SSD 840 PRO Series
- PLEXTOR PX-256M5Pro
smartctl output for both is available here: https://gist.github.com/anonymous/cf8a5208a7315440f796
Relevant past issues
The Plextor drive has always been affected by a reported overheated condition, that I assume is due to the fact it's not an original part
I've seen once the RAID1 being rebuilt after an occasional server reboot, and couldn't explain the reason for that.
A few days ago the Plextor disk was reported in a plain "Failed" status:
physicaldrive 1I:1:1 (port 1I:box 1:bay 1, Solid State SATA, 256.0 GB, Failed)
Thus I unplugged it, checked the SMART output and ran a full test (see smartctl outputs above). The test passed, and even worse seating back the drive gives a perfectly functional RAID1 array.
This is awkward.
I do not know how to let the P410i tell me what is the specific reason for the "Failed" status (I think it's not possible), and I know these are non-original HP parts (thus invalidating my paid HP support), but for this non mission-critical server I'd like to see if it's still possible to keep using non-HP disks and still have some kind of monitoring of their health status.
What is your opinion? I have 3 questions:
- should HP controller monitoring status be trusted only when used with original parts? (this is easy)
- are these (totally non high quality) SSDs objectively in good health?
- shall I give 100% trust to the results of the SMART tests?
Thanks in advance
