Agentless anti-virus (AV) scanning at the hypervisor level has been around for some time now, delivering performance, scalability and scan storm prevention for virtual desktops.
However, if you’re thinking of implementing the same technology to protect your clustered Microsoft virtual servers, please think again!
The vast majority of agentless AV products now all hook in via VMware’s vShield Endpoint technology, causing the scanning process to inadvertently bind to the MS Cluster Virtual Adapter. This introduces a delay which is often enough to initiate continuous failover and failback.
Several options are available to prevent (or resolve) any such issues with a clustered Microsoft virtual server, depending on the specific AV solution in place.
If you would like to know more, or are experiencing problems with agentless anti-virus scanning, why not let BDS help?
