I'm working on a server that ultimately will be used for critical backups of VM images, but also have the ability to spin up a VM (temporarily) if needed. Currently I have 10x3tb nas drives and 2x512 Samsung SSD Pros, 2xquad 5620s and 72GB ECC DDR3. My initial thoughts is raid10 the nas drives with 5x5 and mirror the Samsung (only need 200GB for one datastore). The SSD speeds are of course crazy fast, but I don't seem to be getting performance that I would expect from a 5x3tb stripe either locally or over a 1gb dedicated port.
So to make sure, in a striped volume speed is not limited to 1 drive like ZFS correct? What's also different from what I was expecting is to see 2 volumes mirror (like my hardware raids), but when I use the wizard setup, I see 5 mirrored volumes, it appears the data is spread over all 5 as total space available reflects 5x3tb. Is this correct with the wizard setup? It also leads me to believe, unlike hardware raid10, that I can lose more then one mirror (of course as long as it's not the same mirrored pair) and still have a working datastore?
Here's a snippet of an iozone on a vm over iscsi:
....
Are these normal speeds? I plan on bonding 2x1gb ports for final install. The iozone locally yields faster speeds, but still not what I would expect of 5 stripes. So am I getting a stripe of 5 volumes that are mirrored with all data spread across (and pulled from) the stripes with Wizard or do I need to manually set this up? Thanks for any help!

Are these normal speeds? I plan on bonding 2x1gb ports for final install. The iozone locally yields faster speeds, but still not what I would expect of 5 stripes. So am I getting a stripe of 5 volumes that are mirrored with all data spread across (and pulled from) the stripes with Wizard or do I need to manually set this up? Thanks for any help!
