These three recommended configurations are for Microsoft® Exchange Server 2010 and HP ProLiant SL4540 Gen8 Servers.
They are designed around a building block approach with a multi-copy high availability design using a database availability group (DAG) and can be used to scale to large numbers of users. The DAG provides high availability with multiple copies in a primary datacenter location, and an optional secondary datacenter or disaster recovery (DR) location.
Each design is based on a specific number of servers per DAG which determines the number of users that can be hosted on a single server in a failover scenario. The number of servers per DAG is a flexible design decision that customers can make, and the considerations are detailed in this document.

The HP SL4500 Series is an excellent choice for running Microsoft Exchange Server 2010 and includes both the HP ProLiant SL4540 Gen8 Server and the HP ProLiant SL4545 G7 Server. The HP SL4500 Series is available in one of three configurations (each of these configurations is available in a 4.3U form factor chassis):

  • 1 node configuration – one compute node with up to two small form factor (SFF) 2.5″ hard disk drives (HDD) and up to sixty (60) large form factor (LFF) 3.5″ hard disk drives (HDD).
  • 2 node configuration – two compute nodes, each with up to two small form factor (SFF) 2.5″ hard disk drives (HDD) and up to twenty-five (25) large form factor (LFF) 3.5″ hard disk drives (HDD).
  • 3 node configuration – three compute nodes, each with up to two small form factor (SFF) 2.5″ hard disk drives (HDD) and up to fifteen (15) large form factor (LFF) 3.5″ hard disk drives (HDD).
