Little surprised at other response but here is current information. This is a reference architecture on using current generation HDS Enterprise NFS platform with VMware http://www.hds.com/assets/pdf/deploy-hitachi-ucp-select-for-vmware-vsphere-using-hnas.pdf
HNAS is a rockstar for VMware NFS environments and even delivers lower latency than Brand X FC SAN based environment based on VMmark testing as it uses hardware accelerated filesystem. It thrives on random I/O as effectively you have four controllers in a cluster with some secret sauce for sequentializing random I/O.... Plus, as a VMware admin, it has all the native vCenter adapters plus a VSC like vCenter plugin called Virtual Infrastructure Integrator (V2I).Hitachi NAS V2I_Video - YouTube
Brand N is decent classic filer but there are formidable reasons why we are seen upgrades to an Enterprise NFS platform. I'll let you experience the experience and get off the soap box !
