How well can NexentaStor work with VMware?

I am thinking of replicate SANs across WAN sites.
Say my primary datacenter at HO: All servers are virtual machines in VMware environment, the primary SAN (SAN_p) is provided by NexentaStor at site HO.
And my secondary SAN (SAN_s) is also provided by NexentaStor at site B.

Q#1. Is NexentaStor SAN able to run with VMware Site Recovery Manager (SRM)?

Q#2. Is NexentaStor able to replicate SAN_p to SAN_s over 3Mbps WAN? How efficient is such replication?

Q#3. If SAN_p is destroyed at Site HO, is SAN_s good enough to bring up the same datacenter state at Site B given that I have the same ESX environment as site HO?

Q#4. Is NexentaStor able to work with VMware ESX to 'flush' virtual machine memory state to SAN when 'synching' SAN_p to SAN_s?

Thanks.

What do you mean by 'direct io'? Does it mean 'passthrough' or similar to VMware RDM?
Does it make sense to recover site using NexentaStor replication?
Anyone else is going this path?
I hear people achieve this goal by going with VMware SRM and NetApp SAN replication.
