HP positions ProLiant servers by two criteria line and series to help customers choose the server that best fits their requirements. The relationship between line and series is illustrated in Figure 9-1. Figure 9-1. The ProLiant server family line.The ProLiant server line is designated by the ML, DL, or BL prefix. This prefix designation indicates the type of customer environment for which the server is best suited. 9.2.1 ML LineThe ProLiant ML server line is maximized for internal system expansion. ML servers are designed so that customers can maximize their computing power by adding additional components, such as PCI expansion cards and disk drives, inside the chassis. They are available in both rack and tower models. The highly flexible, configurable design of the ML line enables them to be used in a wide variety of customer environments, including remote sites, branch offices, and data centers. ProLiant ML servers also provide high-availability features to ensure maximum uptime, resulting in price and performance flexibility for the customer. The ProLiant ML330 Generation 3 server is shown in Figure 9-2, and the ProLiant ML530 Generation 2 server is shown in Figure 9-3. Figure 9-2. ProLiant ML330 Generation 3 server.Figure 9-3. ProLiant ML530 Generation 2 server.9.2.2 DL LineThe ProLiant DL server line is density-optimized for rackmount environments. The ProLiant DL line incorporates embedded components that provide a rich feature set at the same time as reducing the chassis size. This makes the servers ideal in dense, space-constrained, and multiserver environments. Available only as rack models, the servers provide the following:
The ProLiant DL360 Generation 3 server is shown in Figure 9-4. Figure 9-4. ProLiant DL360 Generation 3 server DL line.9.2.3 BL LineThe ProLiant BL server line is comprised of ultra-dense server blades optimized for rapid deployment. The ProLiant BL line is designed to help corporate customers and service providers adapt to changing market requirements. The tool-free modularity of the BL architecture conserves limited human and technology resources, maximizes efficiencies, and enables rapid response to customers in a dynamic business climate. ProLiant BL server blades enable rapid deployment, which simplifies and standardizes multiserver deployments. The ProLiant BL line has two classes of products, the BL e-Class and the BL p-Class. The BL e-Class servers offer power-efficient performance for front-end applications by integrating an enterprise-class chipset, ultra-low voltage processor, and other power-saving components in an ultra-dense design. Up to 280 power-efficient edge server blades can fit in a standard rack, providing maximum utilization of data center space. The BL p-Class servers provide high performance and availability for multitiered environments. The BL p-Class infrastructure has centralized, redundant power and offers enhanced management capabilities. Compared to the BL e-Class, the BL p-Class offers higher performance with less density. The ProLiant BL10 e-Class server blade is shown in Figure 9-5, and the ProLiant BL40 p-Class server blade is shown in Figure 9-6. Figure 9-5. ProLiant BL10 e-Class server blade.Figure 9-6.
