MSA30

[Michael Brady_1]

Hello -

We have a new DL360 G4 and we are attempting to get a MSA 30 attached to it. What I am currently looking for is a "best practices for installation" guide or even just general thoughts on this.

Any assistance is greatly appriciated.

Have not used MSA 30, but in general, for better performance, the guidelines are -

If the box supports & if it is okey with your requirement, configure the array in RAID-1 (mirroring) which will give you better through-put in terms of read mb/sec. & write mb/sec. This will give performance as well as security.
If this is not possible, & if box supports, configure it to RAID-1. Although it gives you more space in terms of usable space after RAID, the performance is less than RAID-1. In this case, it is suggested that you keep atleast one HDD as stand-by. If your application is very I/O intensive in terms of writing, then this RAID is not recommanded.

Also, If this model has more that 1 I/O controllers, for better performance, configure the LUNs to be accessed from 2 or more controllers, as this increases the performance to some extent.

The on-controller cache is also a critical factor for performance.

The MSA30 is a simple disk drive enclosure (sometimes called a 'JBOD') - there is no RAID controller embedded.

it comes in either single or dual bus models, obviously the dual bus option will give better performance if disks are spread across both bus's. make sure your RAID controller had enough chanels and buy an aray acelorator

Thank you for the replys everyone.

Currently the MSA30 we have is an SB not DB so the Dual option will not apply for us.

Curious about the RAID1 configuration. I was actually going RAID5 on the array once we have located the actual MSA30 software to set it up.

Other ideas?

The software is ACU. You proably have it already install.

Optionally, you can purchase the DB I/O card and swap them out to have a MSA30DB (vs. your single bus shelf).


RAID1 VS. RAID5.... depends on your applications needs. If you have a Dual buss Smart Array Controller AND you get the DB I/O card replacement, you would be able to configure your Array across both buses.
