4.6 Integrating 1GbE and 10GbE SANs

With the introduction of 10GbE, there will be situations that require 1Gb arrays and 10Gb arrays

coexisting in the same SAN infrastructure. EqualLogic PS Series arrays support operation of 1Gb and

10Gb arrays within the same group. This section summarizes mixed speed SAN design guidelines that

are presented in much more detail in the following publications:

The potential advantages in running a mixed speed (1GbE <-> 10GbE) EqualLogic SAN include:

• Not all of the application workloads on a SAN will require storage I/O performance that the

10Gb arrays provide. Thus, SAN administrators will have additional storage tiering flexibility

based on array I/O performance.

• The PS Series Group Manager will allow the SAN administrator to still manage both types of

arrays within the same SAN group.

• The ability to mix 1Gb and 10Gb arrays supports seamless operational coexistence during

during migration to a 10Gb SAN.
