question.. not sure where to post..!!

[Nathaniel Hall]

The blade servers a separate server.  I suppose you could cluster them 
using software, they are actually separate servers.  We use Dell blades 
at the time.  The shared chassis has a built in KVM and Gig switch.  
Each blade that we order has two processors, two gigs of ram, two 145 
gig SCSI drives raided together and, through the use of the chassis, two 
gig nics.  A USB 1.1 floppy and CD-ROM is used for installation (not at 
the same time).  6 blades can fit into each 3 U chassis and each chassis 
( on the cheaper end) uses 120 volt power.

HP has a similar product, but the chassis is 6 U and uses 240 volt power 
and can usually have 20 blades per enclosure.  The main reason for not 
going with HP, other than power, was the hard drive.  Instead of using 
normal SCSI drives, the model we looked at used IDE laptop drives.  The 
laptop drives spin much slower than other drives, usually 5400 RPMs.

Hope that helped.
