Blades are just an interesting way to collect small form factor servers
together.
Look for a vendor who commits to supporting their blade chassis for some
time, and allows mixing and matching of blade models in one chassis, e.g. so
that you don't need a new chassis every time they upgrade the blades.
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).
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 ;-)
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.
