Paul's right, the new cards scream performance. Now, I would not want to get to the 72 drive limit, but 30, won't break a sweat.

Rule of thumb - Max HDD 72 per pair of 5913.
Max SSD 24-26 per pair of 5913
Yes, you can mix.

Subject: Performance recommendations for pair of 5913s

We are configuring a new machine for our development environment. The first proposal included 30 139Gb drives behind a pair of 5913's. Is that too many drives for a pair of these cards? Wasn't the ROT in the past about 22-24 drives per pair of cache cards, or are these that much better performing?


BTW, I tried to search the midrange-l archives and I get a page that says:

... nothing to see here.

Try Geeky Ramblings instead.
