Although servers can be built from commodity computer components - particularly for low-load and/or non-critical applications - dedicated, high-load, mission-critical servers use specialized hardware that is optimized for the needs of servers. Usually these higher-end servers are loaded with large amounts of disk space, multiple CPUs, large amounts of memory, and multiple gigabit network connections. ISI recommends, resells, and installs server hardware manufactured by HP, the world leader in server hardware shipments.
HP ProLiant Blades (BL) Blade servers are designed to put the most amount of physical servers possible in to the smallest physical area as possible. Blade server chassis are available as rack-mount units or floor-standing units (as shown on the left). Some blade chassis' support hot-swappable blade servers, so you can power down, remove, and replace a failed server from a cluster without affecting the other servers in the cluster.
HP ProLiant Rack Servers (DL) The ProLiant DL series constsis of rack-mountable servers which range from 1U to 7U in size, support anywhere from 1 to 8 processors, and support up to 512GB of RAM depending on model. DL servers are designed for a large range of businesses, from medium to large scale offices.
HP ProLiant Tower Servers (ML) The ProLiant ML series consists of primarily free-standing servers which have standard PC-style footprints. These servers are designed for small office/home office environments, and small branch offices. ProLiant ML servers are designed with cost cutting in mind, while still providing server-grade options like RAID, up to 24 hot-swappable SAS/SATA drives, and up to 144GB of RAM depending on model.
