The DS3524 (with three loaded EXP3524) runs one Array (all 96 drives) in RAID10 carved up in 1TB Logical Drives with 64k blocks and 8MB VMFS Sectors
It's not the Turbo-edition and it only sports the standard Cache (2GB pr. controller)
Write-through caching and Dynamic Pre-fetch off (just ordinary Read-cache).
Cache-mirroring also turned off since we don't use write-back cacheing.
Each of the two controllers int the DS3524 run 4 * 8GBs FC (total of Eight) connections to two Brocade 8GB SAN Switches
ESXi Hosts run two Dual 8GBs FC HBA's each
All Paths are RoundRobin and balances nicely between all available paths to the DS3524
There is no VAAI support on this storage controller yet, but I'm hoping IBM/LSI will deliver in Q1/2011
The Veeam Server is nothing special.
A three year old, recycled HP DL380G5 with two Quad core Intel E5405 cpu's and 32GB RAM
Local disk (for backup) is an IBM EXP3000 with two ESM's (Dual, balanced path with 12 * 2TB SATA disks in RAID5 +HS) attached to an internal HP Smart Array P411 controller.
It attaches to the SAN with one Dual 8GBs FC (Emulex)
Now, going for the 2.5 Inch drives limits the available space (max 146GB at 15k, 300GB disks at 10k, 500GB at 7.2k), but it only uses 8U of rackspace, barely uses any power and hardly generates heat.
The many spindles compensates for the lack of 15k drives so far and IBM has promised they'll allow for at least twice (192) the drives in Q2/2011.
Hopefully there'll be larger 2.5 inch 10k/15k drives by then.
The speed is wonderfull though, considering this is sold as a vSMB, low-end system. It beats all of the Mid-Range systems I've tried (IBM DS5300/DS5020, EMC CLARiiON CX4, HP EVA4400/EVA6400/EVA8400, Dell EQL PS4000/PS6000) so far.
Thanks for posting the detail config.
Btw, I noticed your CPU is "two Quad core Intel E5405 cpu's", FYI, my one and only Veeam server has a single E5620, 2.4Ghz Quad-Core, but I can only get about av 1GB/s max seen on one of the VMs during incremental and CPU already topped 90% during the backup over 1Gbps link, I am using PS6000XV 600GB disks. Lucky you, you can really fully ultilize an old server and reach something like 8GB/s speed on one of your VMs.
But again, anything speed over 1GB/s, I can pretty much say the VM didn't change much and that's why it's not a "real number"
Anton, it would be nice if Veeam can add a row showing Three important stats:
1. The average CPU usage for the job and individual VM backup
2. The average bandwidth used for either SAN or LAN or WAN
3. The target storage processing speed in terms of MB/s. (this is different than simply using total processed VMDK block/time, I think it should somehow represent the real speed on target storage), if you can do it, then please also include IPOS number.
