Hi community,

With SRM 5.1.1, vCenter 5.1.1, SRA 2.0.1.P2 and Iscsi i have performances issues when i test a plan using flexclone.

The recovery site consist in a NetApp Box FAS2220 standalone with 1 RG 11 HDD SATA 1To.

VM are very slow to boot (more than 10 minutes) and lun in the volume clone have high latency report :

52 8 0 0 447 30 98.91 5.03 0 0 /vol/testfailoverClone_nss_v10745371_WIN1_ntap47_2/WIN1_ntap47_2

found this burt and upgrade DOT to 8.1.3P1 but no change.

Write performance on a FlexClone is 50% of a normal Flexible Volume

any idea ?

partially solves witht his burt in Dot 8.1.2P1

Write performance on a FlexClone is 50% of a normal Flexible Volume :

otherwise start vm sequencialy with priorities and dependencies (SRM features)
