We recently asked 3par for some real limit numbers. Their answer of course depends on your connection speed and latency. The number they tend to say they will say is a supportable number is 125MB/sec for a V400 with potential bursts up to 175MB/sec.
if you run statrcopy -hb you can see the throughput currently and average. We can consistently get 70-90MB/sec, but I will tell you that is when 20 volumes are going concurrently as the array is nto very efficient with a handful at a time.
Our WAN is 300 mb with 24ms latency and we use Cisco accelerators that give us a 3x - 5x increase on average in throughput.
Would you mind, either on-list or off-list, telling me a bit more about your IP connectivity? I am getting ready to procure WAN connectivity for 3PAR to 3PAR async replication. WAN optimizers are pricey, especially if one wants redundancy at both ends. At first glance the devices would likely not pay for themselves based on my connectivity costs alone. My link would only be for replication data, not typical remote office activities. Are there other reasons to use a WAN optimizer if you can afford the capacity you need unaccelerated?
