OT Discussion: Do SSD's eliminate the need for RAID?

RAID 1 and RAID 1+0

RAID 1 allows for fault tolerance, you lose a drive, you don't lose your
entire system.
RAID 1+0 allows for the fault tolerance and some expanded space.

RAID 0 should never be used in any type of production environment with any
kind of critical data.

The only time I have ever used or recommended the use of RAID 0 was with
temp file locations or setting up a sever for use only with conversions,
upgrades, and testing.

Subject: [Vantage] OT Discussion: Do SSD's eliminate the need for RAID?

Good morning. Rob Bucek and I were chatting about servers and hardware
yesterday and I thought it would be a good topic to debate.



SSD's are obviously the storage device of the future and keep getting better
and more reliable every day. I'm curious what the hardware gurus on here
think. The largest benefit of RAID is increased I/O performance due to the
spindle bottleneck. Now that we are losing the spindle and opting for the
solid state drives, performance becomes a moot point. There is no I/O
bottleneck anymore.



The only scenario where I see RAID being beneficial with SSD's is with RAID
0 and taking smaller physical drives and coupling them together for one
larger logical drive.



Does anyone have SSD's in a RAID configuration other than RAID 0 out there?
And, why? Just curious...





Have a great day everyone.





Vic

What about Parity? 1+0,5 allow you to loose a drive or two without loss of
production...

This is a repost from June. Still same issue. HELP!!
Â
We're assigning and reporting jobs in Epicor 905.606A. When production is reported through the job, I viewed the WIP Reconciliation report, the materials are coming out of GL accounts WIP 1301-01 and Raw Materials 1303-01, like it’s supposed to. BUT  Finished Goods are hitting the Suspense Account 999-01, not Fin good 1301-01.  The Class and Group are in correct.Â

When we used Kanban Reporting it came out of the correct accounts. Nothing has changed in the Part Maintence Fields.  Is there another option I'm not checking or a step I'm missing?  Â
Appreciate any help, suggestions, ideas you can offer.
Thanks in advance.

We have SSDs on Raid 10. Â It provides fault tolerance and larger logical drives. Â And while it doesn't do anything for read performance, I think it does slightly help the write performance.

I would argue that the point of RAID is for redundancy and fault
tolerance and the increase performance (on spindles) is an added
benefit.

SSD will still fail.
