In order to implement Dell EMC Metro Node active/active cluster for Dell EMC PowerStore systems at two different locations ~80 km apart, besides RTT < 10ms what are recommended values for bandwidth of the WAN ISL links?
Is there any relation between Customer Workload profile (for example 10.000 IOPS, 300 MB/s, Read/Write 80/20, 8 kb block size) and the bandwidth of the WAN ISL link?
Are 2 x 1 Gbps minimum for the Dell EMC Metro Node system or less (for example 2 x 500 Mbps links) can be used?
In general your WAN bandwidth is supposed to be based on the write bandwidth. So if you have 60MB/s that is the required bandwidth for the WAN. While less than whats supported, you could have the account team RPQ this as what is listed is what was tested.
and regarding the zoning configuration, do all devices at each site (server, metronode, powerstore) need to be zoned ? If yes, are the details as follows.
Example zoning in each site
server to metronode server to powerstore
metronode to server metronode to powerstore
powerstore to server powerstore to metronode
SAN switch-1 (top) # zone server to metronode server_fc0; metronode1_fc0; metronode2_fc0;
# zone server to powerstore server_fc0; powerstore_nodeA_fc0; powerstore_nodeB_fc0;
# etc
SAN switch-2 (bottom) # zone server to metronode server_fc1; metronode1_fc1; metronode2_fc1;
# zone server to powerstore server_fc1; powerstore_nodeA_fc1; powerstore_nodeB_fc1;
