I noticed that a server that had been on an iSCSI LUN-based datastore now has a slower ping time at times once it was moved to an NFS-based datastore. Has anyone seen this, and, if so, is it any cause for concern? Is there a way to fix it? I'm moving a larger server to NFS and want to make sure we're not making things worse than it had been on iSCSI (which was very bad, as of late!)
Environment includes two ESX hosts connected to 8 TB usable storage via iSCSI (5 LUNs) and 2 NFS shares. The entire storage backend is in one subnet and is protected from the rest of the network via a firewall.
