Multinode Cluster Hardware Specification¶
Virtual machine requirements are specified in the table below.
| Node type | Quantity | VM | Memory | CPU | Disk | Network |
|---|---|---|---|---|---|---|
| Unified | 4 or 6 | >= VMware 5.1 | 16 GB with 16 GB reservation | 4 vCPU @ 2 GHz with 4000 MHz reservation | 370 GB partitioned:
|
1 Gbit/s minimum |
| WebProxy | 2 | >= VMware 5.1 | 4 GB with 4 GB reservation | 2 vCPU @ 2 GHz with no reservation | 70 GB partitioned:
|
1 Gbit/s minimum |
For Memory and CPU, the Resource Allocation Reservation on VMware is indicated in the table. Hyperthreading is supported.
The OS disk requirement is fixed and logs are rotated to ensure that 10 GB is sufficient. 40 GB for applications is a generous allocation and does not scale with the number of users.
The Database storage partition is sized to support 250 K users. Database backups are compressed and the partition is sized to ensure that sufficient space available to support backup of 250 GB database.
The backup disk should be Thick Provisioned and Eager Zeroed for better performance immediately after installation.
Web Proxies are optional, but if Web Proxies are used, then they form part of the cluster to allow sharing of static data and other content as needed (for example, themes).
To set up the disk requirements, the disk should be set up on the VMware GUI Resources tab where a disk can be created. This task should be done after the OVA import but prior to the boot of the system.
