Diskless servers may be a good fit for medium-size to large businesses, virtualizing their infrastructures. According to this Info World Blog, HP and IBM both offer what they term a 'virtualization blade.' Neither blade has a traditional disk subsystem, opting for either flash or SSD-based boot devices and local storage.
"So imagine a blade chassis designed from the ground up to house completely diskless blades. Not only that, but these blades would be designed without a framebuffer: no disk, no video, just 10G Ethernet and Fibre Channel ports, two low-voltage multicore CPUs, and as many DIMM slots as possible. The power and cooling requirements for such a chassis would be different than those for a traditional chassis, as would possible blade densities. You'd get an awful lot of bang for your power and cooling buck."
Solid state disks (SSDs) made a splash in consumer technology, and now the technology has its eyes on the enterprise storage market. Download this eBook to see what SSDs can do for your infrastructure and review the pros and cons of this potentially game-changing storage technology.
