Hp P4000 Multi-Site San - HP P4000 SAN Technical White Paper

HP P4000 multi-site SAN

In a HP P4000 multi-site SAN configuration, each half of the P4000 nodes in a cluster (or each half of a SAN) lives
in a different physical space—for example, a separate rack, floor, or building. In order to realize the benefits of
10GbE, the link speed between the two locations must be adequate. Specifically:
•
You may need to increase the link speed between the two locations in order to take advantage of the performance
benefit of the 10GbE NICs. (If this is a new installation, the link speed should be 200 MB/s per storage node.)
•
The latency between the two locations must be two milliseconds or less. If these conditions are not met, the benefits
of 10 Gigabit Ethernet will be minimized.
