Yes, this is a good point, but i'm not sure if sometimes complete
revolution is better that just keeping an old standard... Question is
if this is possible that we can use such chassises for long time while
increasing all the time our standards (our needs are still growing...)
HP for example is starting selling new chassises which are not
compatible with previous type, but they are in my opinion much
better... The point is, we have limited space for our cabinets, and we
really need to thing how can we decrease size of our machines (db,
exchg, ts, proxy and many others).

Oh I understand perfectly. We're rolling out some blades this year
ourselves. I'm simply saying that you need to be sure your blade chassis is
in line with your purchasing strategy for your blades... whatever that is.

Think about decent racking space, power provisioning and cooling -
in a fully loaded blade you're pushing a lot of power into the
chassis and will need to remove a lot of heat. Neither of those
happens well without some thought.

This is not a thing i'm afraid of - i have perfect cooling systems ;-)

Yep... you've thought about this part. Too many people don't!

Disk storage is obviously impacted with blades due to the limited
space, in fact you can't meet my personal standard requirements for
an exchange back end server or SQL server on a blade without
involving a SAN also...

Yes, this is true, but we wanted to start without SAN. What are we
thinking about is to use something like Net App Filer solution, where
assigning disks is very flexible.

Well again, you've thought about this which is good. If there are any other
pitfalls I guess we'll both be discovering them at the same time ;-)

I'm always surprised at "professionals" who STILL have to be asked:
"Have you checked (event viewer / syslog)".
