Solution Enabler 7.2 Release Notes Questions

I am looking at moving to VMAX Enginuity 5875.  As part of

this process, I want to get ControlCenter 6.1 UB7 up to Solution Enabler

7.2 and UB9.

There are some questions I have that I want to better understand and

would appreciate anyones input.

1) When I go to download SE 7.2, it shows

"Solution Enabler 7.2 - 32-bit only Supported with ControlCenter"

What does this mean?

Does it mean that SE 7.2 is no longer supported on 32-bit Windows

unless you have ControlCenter running on that 32-bit OS?

2) In the Release Notes for SE 7.2 on page 49 under the "Gatekeeper

sizes in a Windows clustered enviornment", It states that

"For Windows platforms in a clustered environment, gatekeeper devices must be a minimum of 8MB in size and have a signature."

All our hosts use 6 cylinder GKs which is about 2.81 MB and I thought this was pretty standard.  Does this mean

that I can not upgrade these Windows Clusters to SE 7.2 until I replace all the GKs with 8 MB GKs?

Does anyone know why this is?

Ever since we have been building clusters on SE 6.1.1.1 to 7.1.1.18 we have used 6 Cyl GKs...why the change?

Any insight would be appreciated?
