Sizing and resource requirements

Exinda supports:

  • 50Mbps to 10Gbps for Diagnostics
  • 20Mbps to 10Gbps for Diagnostics and Shaping
  • 1Mbps to 1Gbps for Diagnostics, Shaping, and Acceleration

NOTE

The recommended CPU is the minimum number of CPUs to achieve the performance numbers. The CPU must be VT Enabled & 64-bit.

The Exinda virtual appliance has a Flexible Storage option, with which you can adjust the size of the storage for Edge Cache, SMB1 cache and WANWide Area Network Memory cache. By increasing the virtual file sizes for each of these caches, you can greatly improve the performance of your Exinda virtual appliance.

For Edge Cache and SMB1 Cache there is no limit to the size of the file created on the external storage. Use common sense when creating the file sizes. Exinda recommends that 80% of the actual file size be allocated to Edge Cache and SMB1 Cache. For example, if your SMB1 cache is 1TB then the recommendation is 800MB.

For WAN Memory, size should be based on the following:

  • For systems with 2GB RAM – Max WAN Memory Cache is 300GB
  • For all other systems – Max WAN Memory Cache is 1TB

Depending on the WAN bandwidth, use the following sizing specifications to estimate the host resources required for each of the Exinda virtual appliances.

NOTE

On the Exinda Virtual Appliance 10063, the number of CPUs depends on the licensed bandwidth for Diagnostics, Shaping, and Acceleration.

NOTE

In the case of Minimum Disk Storage, storage at higher throughput will require higher disk I/O bandwidth, so the underlying storage should be RAID-based, ideally RAID 10.

IMPORTANT

There are several factors that may mean more or fewer resources are required in individual environments.

Factors that may have an effect include:

  • Quality, speed, performance of the host CPUs.
  • Quality and performance of host NICs.
  • Host disk I/O bandwidth.
