How do you configure these Synthetic Devices? I got Hyper-V running on my laptop and most of the things seems to be fine. I haven't seen the Synthetic Devices option anywhere....

Where are the synthethic devices?

The Synthetic devices are part of the "guest components". In the prerelease bits there is an .iso that include them. Simple mount the .iso and they should auto install.

What about using the iSCSI initiator directly from the virtual server to the SAN?

We have a very robust NetApp FAS-3020. From our other iSCSI initiator connections (on physical servers) and servers that are direct booting from the SAN via iSCSI HBA, we are getting IOPS of approx 20,000 or better per second and 95MBytes per second of data throuput (and higher) using MPIO and Round-Robin connections to the san over multiple iSCSI dedicated nics... (faster than 4mb fiber channel and easily matching direct attached SAS).

With this in mind, is it better for us to use the pass-through to the Virtual Server HOST machine or to directly connect each virtual using the Microsoft iSCSI initiator (within the virtual)?

Thanks,

RB,

iSCSI works great in the guest. iSCSI packets have to traverse the networking stacking both in the guest and the host. Passthrough only does the NTFS stack on the guest and disk stack on the host. The storage paths are much shorter (~4x) over networking.

This means passthrough will be faster.
