Description
Disk allocation for SDX 8900 series appliances is improved with the following firmware releases and newer: 11.1 build 59.x, 12.0 build 58.x, and all 12.1 general availability builds.
With these improvements disk allocation takes place according to the chart at the bottom of this page.
The SDX 8900 series comes with a 240GB SSD Drive and 32 GB RAM. With the 240GB disk, 220GB are available for use. 60GB is used by the SDX Service Virtual Machine (SVM), 10 GB is used for factory partitions, 4GB is used by the Citrix Hypervisor (XenServer). The remainder of approximately 145GB is available for Citrix ADC VPX instances.
Below are guidelines on how much RAM you assign to an Citrix ADC VPX instance, and how much disk size you will use for each instance. If you want to deploy the maximum 7 instances, you must assign 4GB RAM or less to each instance.
| RAM per VPX instance | Disk Size |
|---|---|
| Up to 4GB RAM | 20GB primary disk |
| 4GB to 10GB RAM | 20GB primary disk + 20GB secondary disk = 40 GB total |
| 10 GB+ RAM | 20 GB primary disk + 40GB secondary disk = 60 GB total |
