Planning

To help determine the correct sizing for a Tranzman Appliance, it is recommended that the Tranzman Recorder is used to help better understand the current environment.

A single Tranzman Appliance can be used to convert many environments, the following considerations need to be taken into account when sizing it.

RAM

• Minimum of 2GB of RAM (when If using appliance only for assessments)
• Minimum of 4GB of RAM (when migrating Same Vendor)
• Minimum of 8GB of RAM (when migrating Cross Vendor)
• Additional 1GB of RAM is required for every tape drive connected to the Appliance.

CPU

• Minimum 2 core Intel CPU is required (for Same Vendor or Assessment).
• Minimum 4 core Intel CPU is required (for Cross Vendor).
• Additional 1 core for every tape drive connected to the Appliance.
• ONLY INTEL processors have been tested and are supported.

Network

• 1Gbit minimum connection required (for Same Vendor migration and recovery on Demand).
• 10Gbit connection recommended for Cross Vendor to ensure that tape drive are kept running at a reasonable speed.
• If multiple links are used, aggregation is needed to provide maximum throughput.
• Multiple connections may be required if there are multiple tape drives.

Clients

• OUTBOUND - TCP 30001-55555 to TZM Appliance
• INBOUND - TCP 139 and 445 and UDP 137 and 138 from migration origin. For windows origin clients.
• INBOUND - TCP 111,4045 and 2049 and UDP 111,4045 and 2049 from migration origin. For *nix origin clients.
• OUTBOUND - TCP 139 and 445 and UDP 137 and 138 to all clients. For windows origin clients.
• OUTBOUND - TCP 111,4045 and 2049 and UDP 111,4045 and 2049 to all clients. For windows origin clients.

Server

• INBOUND - TCP 30001-55555 from clients
• INBOUND - TCP 443 from ANY
• INBOUND - TCP 22 from ANY
• INBOUND - TCP 80 from ANY
• INBOUND - TCP 139 and 445 and UDP 137 and 138 from migration origin.
• INBOUND - TCP 111,4045 and 2049 and UDP 111,4045 and 2049 from migration origin.
• OUTBOUND - TCP 139 and 445 and UDP 137 and 138 to all clients
• OUTBOUND - TCP 111,4045 and 2049 and UDP 111,4045 and 2049 to all clients.

Storage

• Minimum 3GB local disk for OS Installation.
• Local/SAN attached disks needed for temporary staging of converted images, sized according to volume of recoveries to accommodate at any one time.

Assessment Only

• Additional disk of Minimum 20GB

Same Vendor

• Additional disk(s) of Minimum ((2.5 X Size of combined catalogs) + (2 X Total Memory))

Cross Vendor

• Additional disk(s) of Minimum ((2.5 X Size of combined catalogs) + (2 X Total Memory) + Largest of either
  • 3 x Largest image size
  • Number of Drives X max size of compressed tape
