VNX vs Netapp failover times in NFS
Hello team,
Customer wants to run its VMware datastores over NFS. We know that failover times for NFS in VNX Datamovers are around 1-2 minute long. Just for the sake of knowing whether that might pose a risk against Netapp or not:
Do Netapp storage arrays last also this amount of time when failing over to the other NFS controller? Or rather Netapp NFS controllers fail over in miliseconds as if they were VNX FC SPs?
Thanks a lot,

My experience with Netapp NFS failover is about 1-2 minutes. However, due to the timeout resiliancy in NFS this doesn´t cause virtual machines to stop/crash. The virtual machines may hang, but not crash.
This is my general experience

I have quite a number of customers using VNX as NFS data stores for ESX servers – no problem there surviving a NDU or reboot
These days VNX is typically below 1 minute for failover time in small to medium configurations – even very very large configs are below 2 mins

So could we conclude that willing to put VMware on NFS in VNX is NOT a technical disadvantage over Netapp arrays??
Thanks,
