The DL2000 NIC ports were set up in a Smart Load Balanced (SLB) team using the Broadcom Advanced Control Suite
(BACS) with receive and transmit buffer sizes set to 1024. TCP Ofoad capabilities are not available to a team with
heterogeneous network adapters. To enable TOE, congure the DL2000 with each GbE port assigned to a separate
subnet. The Dell PowerConnect 6248 10/100/1000BASE-T Ethernet switch was used to connect the DL2000 with the
client systems in a dedicated network environment.

Each MD1000 enclosure contained 15 1TB 7.2K SATA disk drives and disk groups were automatically congured via
the Symantec Backup Exec Storage Provisioning Option (SPO).

The clients ran on Windows Server 2008 64-bit Standard Edition. Synthetic database load for the backup system
clients was generated using the Microsoft Exchange Load Generation tool, version 08.02.0045.000 for Exchange
clients and the RedGate SQL Data Generator version 1.2 for SQL clients.

The size of the total backup set was sufcient to eliminate in-memory caching effects and maintain sustained
performance through a 10 minute measurement interval

Backups were performed in a homogenous application server environment, i.e. the environment consisted of only
Exchange Servers or only SQL Servers). The Exchange Information Stores and SQL databases were backed up in a static
environment, i.e. no transactional database activity was taking place during backup operations.
