Hello, i am about to spend £50,000 on a blade chassis with 6 high spec blade servers capable of running hyper-v on each one.  Each blade would have about 10+ servers on it.  I have had similar quotes from IBM, Dell and HP.
Out of the 3 - has anyone had experience of using these types of chassis and which one do you recommend and why. I like the look of Dell at the moment, namely M1000e.  Also our network is a cisco one.

Thanks, Kevin

We got a free Dell chasis plus 2 blades and an Ethernet I/O module but nobody wants to touch it because we are a HP house.

For hyper-V or any other virtualisation product do your blades have enough DIMM slots and do they have enough I/O? For example the BL490c G6 from HP takes 18 DIMMS and has 2 * 10Gb ethernet on the motherboard. You can get away with less DIM slots but then you need bigger DIMMs which cost more.

What sort of SAN connectivity is Dell offering you? for shared storage in a blade environment SAS connectivity is ideal, do Dell do a SAS switch that you can put in the enclosure or are you stuck with expensive fibrechannel or low performance iSCSI?

Have you actually discussed with HP, Dell and IBM resellers or have you just got quotes from the manufacturer or their web sites?

I have discussed with all three.  Dell recommend:
M1000e chassis
M610 blades x 6
Net App Storage ( we are using this from netApp no matter which of the 3 Companies we go for)

HP are recommending flex10

I can get more detail over to you tommorrow.  I wouldnt mind an honest opinion because they are all in around the same prices for 1 chassis and 6 Blades.  We are buying the netApp seperately.

To be honest with you they all did good presentations and all claim to be better then their competitors.  I really just want to get the one that works and can provide the 4 hour response call out time they are promising.

I'll post the details for IBM and HP tommorrow.

Using NetApp storage with either of the 3 possible solutions:

DELL
M1000e chassis
M610 blades x 6

IBM
IBM eServer BladeCenter(tm) H Chassis with 2x2900W PSU UltraSlim Enhanced Multi-Burner
HS22, Xeon 4C E5530 80W 2.40GHz/1066MHz/8MB L2, 2x2GB, O/Bay 2.5in SATA/SAS
4GB Dual Rank PC3-10600 CL9 ECC DDR3 VLP  RDIMM 1333MHz
IBM UPS 7500XHV - Rack

HP
HP c7000 G6 Blade Enclosure
HP 460c G6 Blade Servers
HPs Virtual connect and Flex 10

Personally i favour the Dell at the moment- what do you think?

It's really down to your I/O modules, the blades all have similar spec and chassis are chassis. Dell use Cisco 10Gb switches, HP virtual connect isn't a switch, appears as on the LAN just like servers so doesn't need spanning tree etc configured.

HP are always pushing Virtual Connect, they have a 10Gb switch as well but I don't think it supports 10GBASE-KR, just the older 10GBASE-KX4 so you would have to buy extra 10Gb mezzanines if you wanted to use switches. You're probably best sticking to the Dell since you already know Cisco and don't need the ability to split the 10Gb onboard NIs into 4 virtual ones.

Thanks for your advice.  We quite like Dell after talking to all three and we are going to go with them.  We also liked to Dell Management Console because we want to create a lights out datacentre.
