Though it is only one part of HPs new or improved virtualization portfolio, the Proliant BL495c virtualization blade also hones the companys broader Blades Everywhere strategy, which aims to deliver discreet or unique blade server solutions for virtually every business need. This prompts a question: Are blades optimum solutions for every business or IT problem, or are they simply one technology among many that can provide businesses the server performance they require?
Technologically, the BL495c is an interesting beast. Like other virtualization-specific server solutions, such as Dells PowerEdge R805 and R905, the new HP box leverages quad core AMD Opteron processors to maximize energy-efficient performance, as well as greatly expanded memory and networking capabilities (up to 128 GB in 16 slots and 8 NICS per BL495c blade) to help reduce or overcome bottlenecks commonly encountered by companies utilizing virtualization to consolidate data center resources.
But though the BL495cs features map well against competing solutions HP has made its virtualization-specific servers a blade-specific play. This brings up an interesting conundrum -- whether businesses leveraging or considering how best to maximize virtualization performance are best served blade architectures.
HP and many other blade proponents would likely argue that their compact form factor, heightened density, integrated networking, and other features make blades the best of all possible solutions for this particular problem.
But to our way of thinking, providing, and maintaining customer choice is a critical issue for vendors to weigh in crafting products and go-to-market strategies. In the case of blades vs. rack-mounted servers, this is not a matter of replacing a doddering, deeply outmoded technology with one that is clearly superior. While blades offer users a number of significant technological and business benefits, their form factor remains their biggest differentiator for many customers, a point illuminated by the fact that while blade sales continue to grow, they are a fraction of those racked up by rack-mounted servers.
