Product Selection by Capacity

Apr 24, 2014

For proper operation, your CloudBridge appliance must have adequate resources to support the number of WAN links that you want to accelerate, and to support all of the users of those links. Three capacities are important when selecting a CloudBridge appliance: link capacity (bandwidth), user capacity, and disk capacity.

Link Capacity

When selecting a CloudBridge appliance, the most important factor is that it support your WAN links. If your site has a single WAN link, your appliance should support your link speed. For example, a CloudBridge 2000-010 can supports links of up to 10 Mbps, which would be suitable for an 8 Mbps link but not a 12 Mbps link. If your site has multiple links that are to be accelerated by a single appliance, the appliance should support the total speed of all these WAN links added together.

The maximum supported speed is determined by a combination of the appliance hardware and the product license. The licensed bandwidth limit is the maximum link speed that is supported by the license.

XenApp/XenDesktop User Capacity

Each appliance is rated for a maximum number ofXenApp or XenDesktop users. This value should not be exceeded when your deployment uses XenApp or XenDesktop. If you are not using XenApp or XenDesktop, consider this number a rough guide to the number of users of other applications.

Disk Size

Disk space is used mostly for compression history, and more disk space results in greater compression performance.

The CloudBridge 4000/5000 series offers from1.8 TB to2.4 TB of disk capacity. That compares to 2.1 TB for the CloudBridge 3000, 470 GB for the CloudBridge 2000, 80 GB for the CloudBridge 800, and 40 GB for the CloudBridge400. CloudBridge VPX has a disk capacity of 100-500 GB. Ideally, an appliance should have a disk capacity larger than the cycle time of the link's data. For example, a link carrying mostly daily update traffic should have 24 hours of disk capacity or more. With a link carrying mostly user sessions, this window can be smaller. (A 1 Mbps link can transfer about 10 GB per day at full speed.)
