an AIM environment, servers mapped to personas will be power-cycled typically during failover and
retarget scenarios.
Apart from the modular chassis switches, two top-of-the-rack PowerConnect 6248 switches are used in
the deployment configuration to perform routing between VLANs and are a redundant pair. The top-of-
the-rack switches are not managed by AIM. Figure 3 shows the physical cabling between the chassis,
EqualLogic arrays, and top-of-the-rack switches.
Figure 3. Physical cabling for Exchange on AIM: rack switches, blades and iSCSI storage
As can be seen from the above figure, there are two top-of-the-rack layer-3 switches that do all the
routing between the different VLANs. They are an active-active pair. The first 12 ports of each switch
are connected via a 2-port trunk to the M6220 modular switches are the back of the M1000e modular
enclosure. Ports 13-20 are used for iSCSI connections to the Exchange mailbox stores on two EqualLogic
PS 6000E enclosures. Port 21 is a direct connection to the CMC modules in the blade chassis. Ports 23-
24 are used for the iSCSI persona store on an EqualLogic PS 4000X. In the setup two 10Gbps uplink
modules were used to provide connectivity between the switches and Virtual Router Redundancy
Protocol (VRRP) was enabled. As an alternative to the 10Gbps links, the user may consider using
multiple trunked 1 Gbps links between the switches with the same configuration.
