Hi. Same problem with DP 7.01 as in DP 6.21. Very slow DA on virtual fileserver with Win2003 or Win2008 R2 or Win2012 Datacenter. Only about 20-40 MB/sec backup speed from VM in VMware vSphere cluster to D2D 4112.
We have HP Network Team with 2 Gbit/sec connection for MA server (DL360 G7) and then flow goes to D2D 4112 connected by SAN 8 Gbit/sec. Our vSphere cluster is HP BladeSystem c3000 with BL490c G7 and 2 HP Virtual connect Flex-10 interconnect modules. VM's vmdk files are on EMC CX4-120 CLARiiON with 15 FC disks + 4 SATA II disks.
I try to divide my large file server to some Objects on same Windows volume, but no success. Speed is very low.
I try everything what i found in docs and on this forum, but speed still the same.
