PERC Raid Card Confusion - to use in a custom VMware server

post #1 of 7
Thread Starter 
I'm an IT guy. I'm building a server for VMware from a i7 computer for my own office. I need a good card for RAID 10. I live in Austin Texas so there is lots of used Dell equipment to be had. I am interested in a PERC 5 or 6.

Here is where I am confused:
  1. These are PCI-E x8 interface. Right ...Will these work in a PCI-E x16 slot?
  2. Don't really understand the difference between the 5/i and the 5/iR ...don't they both do RAID?
  3. Is a 6/i better than a 5?
  4. What about the "e" versions and running the drives in a external drive box?
  5. Will all of the PERC 5/i and PERC 6/i cards run regular SATA II drives with the right cables?
  6. Are there any array size or drive size limitations with any of these?
  7. There are many different part numbers for the PERC 5/i controller. I see the TU005 and the WX072 for sale a lot. Is there anything to know about all the different PN#'s? ...or are they all really the same?

Thanks much for your help.

@OP

1. Yes

2. The 5/i you refer to is the PERC 5/i, a SAS hardware RAID HBA supporting up to RAID 5 across 8 drives. The 5/iR you refer to is the SAS 5/iR, a SAS HBA which supports RAID levels 0 and 1 across 4 drives.

3. Yes. The PERC 6/i supports RAID 6 and has higher bandwidth.

4. The PERC 5/e and PERC 6/e as you say, support drives in external cases. The PERC 6/e in particular has 512MB of onboard cache, as opposed to the PERC 6/i's 256MB. Additionally, the /e variants support more than 8 drives and also support the use of SAS expanders, which means you can also use them to control internal drives in a high-drive-count chassis such as the Norco 4224.

5. Yes. You need SFF-8484 forward breakout cables

6. Yes. The PERC 5/i and 6/i will logically support only 8 drives (16 for the PERC 6/i). This is a firmware limitation. The PERC 6/e will support up to 144 drives; I assume the PERC 5/e will be similar.

7. Generally, they are identical apart from firmware revisions (perhaps). Just make sure you get one either with a PCI bracket or with the holes to support one. Oh, and try to get a PERC 6/i rather than a 5/i. smile.gif

Look here for more information.

parityboy, thank you very much. That is great information.

I found a 6/eR, will this do RAID 5 or, even better, RAID 10? Here is the link:

As far as I am aware there is no "PERC 6/eR"; there is the PERC 6/e (a true hardware RAID card), and the SAS 6/iR (a SAS HBA which supports RAID levels 0 & 1). I own one of each. smile.gif

The picture in the link is of a PERC 6/e. If you follow the link I supplied, you will see in the table that it supports RAID levels 0,1,5,6,10,50 & 60. smile.gif Are your drives going to be housed internally or externally? How many drives are you looking to support?

I just clicked further into the item description and it looks like it is a regular 6/e. It looks like it is equipped with 256MB RAM, can that be upgraded later to the 512 if I decided to? ...or is it spec'd that way from the start and cannot be changed?

Also, any thoughts on trying to work with a H200 or H700 instead?

Again, THANKS!

It's removable, so yes I think you can. As for the other two cards: the H200 is a basic SAS HBA which has extended support for non-parity RAID topologies, i.e. RAID 0,1 and 10. It also supports non-RAID JBOD. The H700 (and H800) is a (very expensive) true hardware RAID card which has support for parity RAID levels 5 & 6, but not JBOD.

If you don't need to use parity RAID, or don't need RAID at all, or want to use software RAID instead, and want to support 8 or more drives (via a SAS expander), get the H200.

If you need true on-card RAID 5 or RAID 6 processing, get the H700. If you need the same with external drives and/or SAS expanders, get the H800.
