Accusys A08S-PS - Best Configuration?

Hi Resolve Gurus,

We have a Accusys A08S-PS as our storage for our Resolve suite.

I was just wondering what is the recommend configuration for the RAID controller?

Will RAID-5 or RAID-6 give the best performance in a 8-bay setup?

Do you recommend enabling Performance Equalisation?

Any advice would be greatly appreciated!

Thanks!

Best Regards, Chris!

Hi,
I am using raid 5 with my JMR unit. Atto SAS.
One hickup in 2 1/2 years.
There is quite a lot on the merrits of raid 6
on the internet.

Using raid 50 for backup units.

Best of luck
Radman.

Thanks for your feedback - greatly appreciated.

I'm more concerned about performance than redundancy, as we always have a backup of all the media and projects anyway (so if a drive did go down we could just replace the faulty drive, format the RAID, then copy across the media again - which would probably be faster than a RAID re-build anyway).

I guess I'll just have to do some tests!

I'm assuming that RAID-6 will have slightly faster read times than RAID-5, and RAID-5 will have slightly faster write times than RAID-6 - but I'm very curious to see how RAID-0 would perform in comparison.

I'm also really curious to see at what point adding drives to a RAID-0 array will start to have less of an affect (i.e. it might be better to have two sets of four drives in a RAID-0 array rather than have eight drives in a RAID-0 array). I guess it will all depend on how the Accusys RAID controller has been optimised - as I'd imagine most of the time end-users will be using RAID5/6.

I'll do some tests later next week - but if anyone has some insight, let me know!

Thanks!

Hi Chris,

I got my facts slightly wrong my apologies. Under pressure here.

JMR is Raid 0 as I have backup at Raid 50 on another system. ( Raid 0 giving me 800MB/s. )
My G-Tech drives are configured at raid 5. There is a drop in performance as you are well aware of.

The performance of raid 0 makes a big big difference to both Avid Symphony and Resolve.
I would go raid 0 if you can afford to.
Make sure you are using enterprise drives. ( Hitachi are the best )

Cheers
Radman.

Thanks Radman!

Yes - we have enterprise drives, so I'll do a comparison between RAID-0, RAID-5 and RAID-6 when I get a chance. Stay tuned!
