back to article HP launches siamese-twin server blade

Hewlett-Packard has devised a siamese-twin CPU server blade for those monstrous data centers with nowhere to spread out. HP pitches its new ProLiant BL2x220c G5 as the first blade with two independent servers combined into a single blade enclosure. The twofer is intended for large "scale-out" operations that require massive …

A better alternative if you want to take the cost out

Where's the beef?

What, only 4GB of RAM each? Seems to be a bottle neck for today's VM world.

idataplex competitor

This is more like idataplex competitor aimed at ultra high compute density market. Each blade can have only 8GB max RAM to feed 8 cores, and little IO, but you get so many of these discrete 2-socket physical servers in little space. Most HPC/web2.0 customers probably do not need a lot of memory so this may work out well for them. HP is charging quite a premium for this kind of density with this solution. While idataplex has liquid cooling integrated, it would be interesting to know whether there is any integrated liquid cooling at work here.

wouldnt true lower cost be based on how many you can amortize per rack?

wouldnt these 128 200W servers in a rack with hp water cabinet be lower cost to own than 42 230W idataplex with their water rack - neither adds heat to data center?

Maximum memory is per node

The memory is 16GB per node not per blade so it would be 16GB for 8 cores

Fuzz is right

Fuzz is right, It's 16GB per server and they're not being aimed at heavy VM usage, more for compute-heavy or forced-scale-out environments.

Also in reference to the IBM iDataplex, they're not in the same league - two racks-worth of these this HP blade model equals 2048 xeon cores and 4TB of memory and are already shipping. It's hard to find details on the IBM system but it looks like they only get either 800 or 1600 cores into the same space, plus of course you end up building your environment two-racks at a time - not always 'do-able'. Oh and they're coming in July.
