               Improve Your Backup Server Performance with TOE Acceleration


               Brief Summary
               In recent backup server tests with Alacritech® Accelerators versus conventional NICs,
               Alacritech provided overall backup efficiencies including:
                        • backup throughput performance improvements of 30%
                        • substantial reduction of backup times
                        • release of CPU resources for other tasks

               Backup Servers - Improving Their Performance and Efficiency
               Customers are increasingly constrained by large transfers of data backup, long backup times to storage devices, and less
               efficient use of server resources as a result. System and database availability is heavily impacted during backup periods,
               and with the rapid growth of storage and the need to archive customer data, IT managers are actively seeking solutions
               for their backup problems.

                                 Accelerating Data Delivery™
                Alacritech Backup Server Brief Continued
                A comparison of the data shows Alacritech with a 30% increase in overall backup efficiency with industry standard soft-
                ware and high performance tape devices. Server environments with more efficient data sets can increase their over-
                all backup performance even more. Results from Computer Associates BrightStor Enterprise Backup, VERITAS
                NetBackup, CommVault Galaxy and Legato NetWorker also show similar increases in backup performance. With addi-
                tional system performance tuning and configuration changes, even greater throughput and efficiencies could be
                achieved.

                TOE Solutions From Alacritech
                Today’s growing IT departments are constantly bombarded with new challenges in server growth, storage manage-
                ment and data migration. Data center resources are focused on the challenge of moving data to users that need it
                now. This increased emphasis in data management has led CIOs, CTOs and other IT executives to look for network
                technologies for their servers that help them solve this increasingly difficult problem.

                Alacritech is the pioneer in providing reliable and efficient data movement technologies for network acceleration
   TCP/IP       today. Servers starved for network processing power and a need for better application performance should look no further
   Offload      than the TCP/IP Offload Engine (TOE) capabilities provided by Alacritech Server and Storage Accelerators. This break-
                through technology has provided thousands of customers with efficient, high performance network interfaces that
Engine (TOE)    focus on an IT department’s need for better flow of data from the network to servers to storage and back.
 technology
                The power behind Alacritech’s design is SLIC Technology®, a revolutionary way of taking network data and
                accelerating it through servers. This solution gives servers the freedom to focus less resources on net-
                work data transfers and more on doing the job the server was really designed to do. Customers can
                replace their current server NICs with Alacritech Accelerators and see an immediate benefit in both server
                efficiency and response time. SLIC Technology provides higher levels of network throughput, better appli-
                cation performance and a maximum return on investment (ROI) with servers in production today.
