The Facts…and Fiction about blades The first blade server without compromise – Dell delivers on the promise of high density computing with a blade server featuring the latest high performance server technologies, plus total cost of ownership and density advantages over traditional Dell 1U servers. No blade server has ever been this sharp. PowerEdge 1955 Product Details

Blades are an Option, NOT a Mandate When it comes to servers, Dell’s approach is simple: provide a solution with the right platforms to address each customer’s unique needs. Helping customers solve their challenges by making IT simple is the Dell difference. Other blade vendors have pushed “Blade Everything” agendas, focused on creating extensive proprietary lock-in architectures that ultimately benefit the vendors, not end users. Dell considers blades a natural extension of the PowerEdge server product line, and blades can be an integral part of an IT solution. But blades are not a one-size-fits-all solution for all IT problems; Dell considers blades a platform choice, not a mandate. It’s time to ignore the marketing spin and hype from other blade vendors. IT professionals need real solutions to address IT complexity. By working with Dell, customers have a partner that can build custom solutions with the right platforms to help maximize datacenter effectiveness and simplify IT. To hear more about Dell’s blade strategy, listen to some plain talk from Glenn Keels from Dell’s server group and resident blade expert on the Dell podcast Fact vs. fiction: Blade everything data center. What Analysts and Press are saying about blades: IT Organizations should expect vendors to put enormous pressure on them to adopt blade technology; however, blade server technology is not fully mature. – Gartner, Inc., Feb. 20071 We give Dell credit for cutting back on the blade hype. Too many customers have been burned – sometimes literally – by the big vendor blade pitch. – The Register, May 20072 PowerEdge 1955 Product Details

No spin, no hype: Dell PowerEdge Blades are Simpler, Faster, and Cooler With the “Blade Everything” agenda in the proper perspective, Blade servers can be an answer, as a rapidly emerging technology, to address space constraints, reduce power consumption on a per server basis, and reduce overall management and maintenance costs. When applied appropriately blades have impressive total cost of ownership advantages and here are some facts on why Dell PowerEdge Blades are the best: Simpler – Dell is the ONLY vendor that fully configures and factory tests each blade to customer specifications. In addition, Dell ships blade server in fewer boxes than other vendors. In fact, an independent 3rd party evaluator received similar orders of Dell PowerEdge blades and HP c-Class blades, the Dell blades came in 2 boxes, HP came in 78 boxes3. Dell simplifies the total ordering and implementation process from start to finish. Best Blade Performance – Dell PowerEdge blades posted the best SPEChpc benchmark performance scores in the InfoWorld “Battle of the Blades” head to head comparison5. As well, an independent 3rd party comparison of Dell PowerEdge vs. HP c-Class blades showed the Dell blades outperformed HP in the SPECjbb2005 benchmark.6 Dell delivers the performance necessary for mission critical workloads. Best Power Efficiency and Performance/Watt – Dell PowerEdge blades are up to 16% more power efficient than HP and IBM, according to the publicly available online calculators available from the manufacturers (see Figure 1). Also, an independent 3rd party comparison of Dell PowerEdge vs. HP c-Class blades showed the Dell Blades draw less power, and provide up to 8% better performance per watt over HP blades4. Every watt counts and Dell blades help lower utility bills and enable increased capacity. Figure 1 – Power comparison using each manufacturers online power calculators PowerEdge 1955 Product Details

Speeding Up Deployment and Easing Management Dell believes that customers should not be forced to choose a systems management strategy based on their hardware vendor of choice or the form factor of a server. Why should managing blade servers be any different from managing other servers? Dell’s partnerships with industry leaders allow choice and flexibility with integration into leading 3rd party enterprise management applications and existing management infrastructures such as Microsoft and Altiris . Physical deployment of servers can be greatly accelerated by utilizing blade servers. With individual rack servers, each server must be installed separately. With blade servers, once the time investment has been made to install the blade chassis, adding an additional server to the chassis is as simple as sliding a blade server into the chassis and powering up the blade. Just like other PowerEdge servers, the PowerEdge 1955 is easy to manage with the intuitive suite of Dell OpenManageTM products for deployment, change management, and monitoring. Once the blade server is installed in the chassis, the server can easily be provisioned with existing tools like those from Dell, Microsoft or Altiris. A port in the front of each blade server is also available to enable USB ports for provisioning the server with external USB media like CD-ROM, floppy drive or USB key devices. The DRAC/MC (shown below) also provides remote management of the enclosure and blade servers including power control, event log reporting, and inventory reporting. In addition, a second DRAC/MC module is available for active/passive redundancy. In addition to the DRAC/MC, the Avocent Digital Access KVM switch can enhance remote management capabilities with support for remote graphical console redirection, virtual media support, and seamless tiering into existing Dell or Avocent KVM infrastructures.
