Windows Server 2012R2 on BL460 G8 as file server with 3par cluster extension very slow

[Albert3009]

Hi all,

currenty we are facing issues with 2 cluster (both 2-node cluster) based on Windows 2012 R2 with 3par 7400 remote copied LUNs and HPE cluster extension 4.x. Active node runs a while and crashes. Hardware is based on BL460 G8 (2 x 8-core, 265GB RAM) with newest drivers, firmware, etc. based on SPP2016-10.

When cluster node stucks and you switch from active to standby node, it takes ~ 20min and standby node cont. working. Same shows up, when standby runs a while. Switch to prev. active node helps again.

Any idea
