Actually there are a whole lot more considerations. We use HP blades.
1. Power, you have to have enough of it to power the blade center and the
proper connectors.
2. Computer room floor. There must be enough ventilation in front of and
behind it and also it must be able to support an enormous amount of weight.
3. Computer room temperature. You could heat a 5 story apartment complex
from the heat these things throw off. You have to make sure that your computer
room can handle it.
4. Network considerations...you are adding massive amount of servers to it
all at once..be sure your network is up to the task. Our blade system uses
multiple (like 50 total) internal for management and external IP's Thinks it
through carefully.
5. I would wait until Lonhorn comes out in Q1 07 to implement.
6. Buy 64 bit.
Just my .02.

It looks like I'm going to be moving into the land of Blade servers.
We're a Dell shop, so Dell 1955's are what is being looked at right now. I want
to put together a host list of key items to make sure these things
have/support. Memory backed RAID cache and power issues are the only thing I
have on the list now, since that was the main issues I've seen come across the
list. Obviously, management of the blade chassis is important.
If it's useful, here is what we are planning to do with the Blades:
There is no intention of moving our Citrix farm to blades, but we are
deploying a new business level app using VMWare ESX3. This new app will
utilize web servers and SQL servers. The web farms will be in ESX and will
utilize an application load balancer, the SQL servers (starting with 1) will
likely not be in ESX, but that is undecided.
We will have a fiber connected SAN as well, but the plan isn't to boot off
the SAN (right now at least). It is unknown if we will connect the entire
blade chassis to the SAN, or servers individually. It depends on the cost of
the fiber switches.
We are doing a lot of server consolidation as well to 2 existing 2850 (dual
3.4ghz Xeon's) running ESX3. As we need more capacity, we will use additional
Blades for ESX 3 and consolidation.
The 10 blade chassis specs out to about 6k. Each 3ghz Dual Core (woodcrest)
blade with 16 gigs of RAM, 2x75gig SAS drives and dual Broadcom TOE GigE/dual
QLogic Fiber HBA's will run us about $6600 (including warranty/support)
