Confidential Backup Performance Concurrent backups into ExaGrid Client/Agent performance Data types and affect on performance Network performance Backup server performance All of these must be providing optimal performance for a ExaGrid B2D environment to operate at maximum speed. Most backup environments are optimized for tape and performance issues do not show up until B2D is installed, resulting in the perception of poor performance.

16. TechTarget Backup School New Customer Training exagrid.com | 16© 2014 ExaGrid Systems, Inc. Confidential Replication Rule of thumb: 3mbit/sec per TB of data being backed up (This is assuming a 2% change rate.) This must be dedicated to the ExaGrid 24 hours a day. Adjust bandwidth accordingly. i.e. If need to black out 12 hours per day than one would need 6mbit/sec per TB of data being backed up. What might require additional bandwidth: Compressed data Higher change rates A lot of new data or day 1 load (Initial seed will require much higher bandwidth. May need to colocate ExaGrids for initial replication.)

17. TechTarget Backup School New Customer Training exagrid.com | 17© 2014 ExaGrid Systems, Inc. Confidential Networking (4.6 and below) Each ExaGrid Site must be on its own VLAN. One port on the ExaGrid is used in ExaGrid server to ExaGrid server communication (backpanel) Multicasting is used only between ExaGrid Servers in an ExaGrid Site. Via NIC1, multicast packets must not be routed between ExaGrid Sites. When setting up a subnet for an ExaGrid Site’s NIC1 port, ensure that standard multicasting protocols such as IGMP/IGMP snooping or multicast routing protocols like DVMRP, PIM, and MOSPF are disabled on the subnet used by your ExaGrid system.
