We are currently using Clariion CX700 disk arrays for B2D. We did find that RAID-5 was the best performance for our testing. We also found that some environments performed better at 4+1 and some performed better at 7+1. We are in the process of migrating off the Clariion on to a IBM/NetApp 55

Agreed.  70MB/sec writes is disappointing but acceptable for my requirements.  On a fast cpu machine you'll see better performance with software raid.  That's normal.  There's lots of other reasons to go with 3ware.  Here's what led me there: - Auto-sector repair.  With big disks, this is critical.

I have two Linux media servers setup with 3ware 9500S controllers using raid "50" with  seagate disks.  With our configuration this is two raid 5's of 6 disks each that are then striped together.  I get up to about 70MB/sec writes and 300MB/sec reads after the readahead is tweaked up.  They are us

Hi Monte,   I did one install with EMC DMX1000 disk with hardware mirroring used for a DSSU and I have to say I found performance wasn't great. Worse than LTO2 performance but this was writing to a fairly small number of physical drives, though performance wasn't an issue so I didn't spend a lot

<> That is at the minimum required for LTO3. Is anyone using LTO3 for D2D2T? I'd like to understand what does and what does not work. There is some pressure to start using LTO3 as the price gap narrows, but I doubt many of our systems can deliver the data rate even off local disk. I thin
