Hardware Specifications for Non-Deduplication Mode

The following are the hardware requirements for MediaAgent for Tape, Disk, Cloud, and Index Cache. For more information on system requirements, see System Requirement for MediaAgent.

Important:

  • The following hardware requirements are applicable for non-deduplication MediaAgents.
  • The suggested workloads are not software limitations, rather design guidelines for sizing under specific conditions.
Components Extra Large Large Medium Small
CPU/RAM 12 CPU cores, 64 GB RAM 8 CPU cores, 48 GB RAM 4 CPU cores, 32 GB RAM (or 6 vCPUs/32 GB) 4 CPU cores, 24 GB RAM (or 4 vCPUs/24 GB)
OS or Software Disk 400 GB usable disk, min 4 spindles 15K RPM or higher OR SSD class disk 400 GB usable disk, min 4 spindles 15K RPM or higher OR SSD class disk 400 GB usable disk, min 4 spindles 15K RPM 400 GB usable disk, min 2 spindles 15K RPM
Index Cache Disk[4] 2 TB usable with 800+ IOPs [1] [2]

Note: SSD Class Disk/PCIe IO Cards is recommended for certain workloads

For example: an extra large Exchange Mailbox Agent index server can contain 1 billion messages. See Configurations for the Exchange Mailbox Agent Index Server.

1.2 TB usable with 800+ IOPs [1]

Note: SSD Class Disk/PCIe IO Cards is recommended for certain workloads[3]

For example: a  large Exchange Mailbox Agent index server can contain 750 million messages. See Configurations for the Exchange Mailbox Agent Index Server.

500 GB usable with 400+ random IOPs

For example: a  medium Exchange Mailbox Agent index server can contain 500 million messages. See Configurations for the Exchange Mailbox Agent Index Server.

200 GB usable with 200+ random IOPS

For example: a  large Exchange Mailbox Agent index server can contain 250 million messages. See Configurations for the Exchange Mailbox Agent Index Server.

Suggested Workloads
Parallel Data Stream Transfers 300 200 100 50
Front End Terabytes (FET) 240 TB 200 TB 80 TB 50 TB

Notes:

  • For large data sets that exceeds suggested capacity, we recommend that you group the similar data type agents for backups, such as File System agents, Database agents and so on.
  • The TB values are base-2.
  1. SSD class disk indicates PCIe based cards or internal dedicated endurance value drives.
  2. Recommendation for unstructured data types like files, VMs and granular messages. Structured data types like application, databases and so on need significantly less index cache.
  3. For the following data-intensive use cases, placing your index data on a solid-state drive (SSD) might provide better indexing performance:
    • Exchange Mailbox Agent

    • Virtual Server Agents

    • NAS filers running NDMP backups

    • Backing up large file servers

    • SharePoint Agents

    • Ensuring maximum performance whenever it is critical

  4. Assumes retention of up to 15 days.
