Dell EMC Metro Node - WAN ISL link bandwidth
Hi,
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?
Thanks,

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.

Hi All,
how should the cabling topology be used for Powerstore block optimized with Metro Node ?
Skenario-1
or Skenario-2
I'm not sure about scenario-2, because wan cabling should be directed to the network switch.
please advise,
Thanks,

Correct, scenario 1 is correct assuming that your WAN is going through a switch

Hi All,
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;
# etc
Thanks,

server to powerstore is not needed.
server to metronode, metronode to powerstore is all
