We plan of buying the IBM Blade Server S for virtualization. We want to know performance vice how the server and we going to use the VM Ware Vsphere5 in that for HYPERVISING.

And our VM’s requirement is 40-50 with 2GB each.

Please let us know how server for virtualization.

    You can have some info on IBM BLADE

    IBM has some good Redbooks in the Blade Centers.

     Blade server are exactly the same as standalone servers. The only difference is physically how the servers connect to the "external" world (Ethernet, Fiber Channel, Infiniband). The blades use back/mid-plane connects to the I/O modules within the chassis and then the I/O modules have external connections to the rest of the world. All Ethernet switch modules for a blade center are managed switches. So you go into the switch and configure the ports for the appropriate VLAN. Blade has Own CPU and memory Own SCSI drives, depends on the models and  each server can have its own disk drives. As example Each Blade has Intel Quad Core 2.6GHz CPU with 96GB RAM, 2 Gig NICs.

    The best way to 'know' if your systems is "ok" with VMware is to check VMware's HCL:
    http://www.vmware.com/resources/compatibility/search.php

    Probably you want more nics in the blades for better performance ( 2 nics for the service console and vmotion, and 2 for the production network),  you will need to route all traffic to two nics.

    If you are  building virtual environment on single Blade Center? Pro is less power consumption/cooling/space/Less costs an external datacenter. Also centralized management (central RSA etc). Con iof one chassis is the possibility of a failing component like a backplain on the enclosure. This will result in downtime of your blades and you virtuals.

    At the end of the day it depends on how the blade server are configured you put into the blade chassis, both hardware and logical wise.

    Performance vice it is impossible to say: 
    If you use single quad-core Xeon configurations for the blades and try to run some excessive calculations on each VM the system may fall short. If those VMs run webserver, mailserver and stuff like that it it should be able to run those VMs without any problem.I found a nice article about VMware on blade systems you probably want to read:http://www.hypervizor.com/2010/04/vmware-vsphere-on-ibm-bladecenter-h-part-1-of-2/http://www.hypervizor.com/2010/08/vmware-vsphere-on-ibm-bladecenter-hpart-2-of-2/
