Headline

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.

Ports

The appliance needs to communicate over the network. If you have internal firewalls, you must allow the following connections or the appliance cannot function.

Backup Servers (Clients of Tranzman)

All servers:

  • OUTBOUND - to Tranzman Appliance TCP 55001-55555

Destination servers:

  • Windows
    • OUTBOUND - to the Tranzman Appliance TCP 139 and 445 and UDP 137 and 138.
  • *nix
    • OUTBOUND - to the Tranzman Appliance TCP 111,4045 and 2049 and UDP 111,4045 and 2049.

Tranzman Appliance (Server)

  • INBOUND - TCP 443 from ANY
  • INBOUND - TCP 22 from ANY
  • INBOUND - TCP 80 from ANY
  • INBOUND - TCP 55001-55555 from all origin and destination backup servers
  • INBOUND - TCP 139 and 445 and UDP 137 and 138 from destination Windows servers.
  • INBOUND - TCP 111,4045 and 2049 and UDP 111,4045 and 2049 from destination *nix servers.
  • INBOUND - TCP 139 and 445 and UDP 137 and 138 from Administration PC(s) Windows Only.
  • OUTBOUND - TCP 53 and UDP 53 to the DNS servers.
  • OUTBOUND - UDP 123 to the NTP servers.
  • INBOUND - UDP 123 to the NTP servers.
  • OUTBOUND - TCP 25, 587 to the Email server.

Administration PC

  • OUTBOUND - to Tranzman Appliance TCP 443
  • OUTBOUND - to Tranzman Appliance TCP 80
  • OUTBOUND - to Tranzman Appliance TCP 22
  • OUTBOUND - to the Tranzman Appliance TCP 139 and 445 and UDP 137 and 138.

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. The following is for guidance only, it would be recommended that you use the Tranzman Recorder and Stone Ram Consulting Services to correctly size the volumes.

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
