We are planning to change from IBM servers to Dell Power edge M620 blade servers. right now our SAN storage EMC VNX 5300 with 2 brocade DS-5100B switches.
now how the M620 blade servers will connect to our existing EMC SAN storage???Dell people they suggest 2 brocade M5424 FC8 switches. but i don't understand how this configuration will be done since i already have 2 brocade switches????
after searching on dell website i found Pass Through module and i understand that it will only pass the fiber connection to the existing brocade switches. so no need for the 2 brocade switches which dell propose.
Can you help me in this and share with me your idea about this issue. shall i go to switches or get Pass Through module.
With blade FC switches you can use access gateway features (active by default) that permit easly to threat them as pass-thought switches.
Just 2 cables per switch that are similar to a LAG in Ethernet switches
There are many advantages of using PTM(Pass through) as you have an existing FC SAN infrastructure. Prime advantages are listed below.
