Virtualized Hardware and Resource Oversubscription#

It is recommended that no more than two Unified nodes and one Web Proxy node be run on a physical server (VMware server) and that the disk subsystems are unique for each Unified node.

VOSS Automate virtual machines should maintain a 1:1 ratio between virtual RAM and Disk hardware and physical hardware, in other words:

  • 1 GB of virtual RAM (vRAM) must map to 1 GB of physical RAM

  • 1 GB of virtual Disk (vDisk) storage must map to 1 GB of physical storage

For virtual CPU (vCPU), hyper-threading is supported.

Unified Node Hardware Specifications#

Single-node Cluster (cluster-of-one) Hardware Specification#

This section provides the virtual machine specification for a single node cluster deployment topology in VOSS Automate.

Single node cluster

1

>= VMware 11

16 GB with 16 GB reservation

4 vCPU @ 2 GHz with 4000 MHz reservation

370 GB partitioned:

  • 20 GB for OS

  • 50 GB for application: 10 GB for logs, 40GB for our apps

  • 50 GB for compressed backups

  • 250 GB for database

70 GB database disk to be added after upgrade or installation. Refer to the Upgrade Guide with ISO and Template or Installation Guide.

1 Gbit/s minimum

For Memory and CPU, the Resource Allocation Reservation on VMware is indicated in the table. Hyper-threading is supported.

Note

  • From release 24.1, allowance should be made for an additional 70GB database disk to be added after upgrade or installation. This disk will be used for Insights sync.

    Refer to the Upgrade Guide with ISO and Template or Installation Guide.

  • If memory allocations are customized, ensure that the memory reservation remains equal to the allocated memory in order to prevent possible negative side-effects due to memory reclamation.

For VMware details, refer to VMware Support.

The maximum number of users for a single node cluster is 50,000.

  • 20 GB for OS

  • 50 GB for application: 10 GB for logs, 40GB for our apps

  • 50 GB for compressed backups

  • 250 GB for database

70 GB database disk to be added after upgrade or installation. Refer to the Upgrade Guide with ISO and Template or Installation Guide.

1 Gbit/s minimum

>= VMware 11

4 GB with 4 GB reservation

2 vCPU @ 2 GHz with no reservation

70 GB partitioned:

  • 20 GB for OS

  • 50 GB for application

1 Gbit/s minimum

For Memory and CPU, the Resource Allocation Reservation on VMware is indicated in the table. Hyper-threading is supported.

Note

  • From release 24.1, allowance should be made for an additional 70GB database disk to be added after upgrade or installation. This disk will be used for Insights sync.

    Refer to the Upgrade Guide with ISO and Template or Installation Guide.

  • If memory allocations are customized, ensure that the memory reservation remains equal to the allocated memory in order to prevent possible negative side-effects due to memory reclamation.

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.

Note

To change the TRANSACTION_LOG cap size to greater than 10GB at larger providers for operational reasons, for example for diagnostics and a longer transaction replay window, the voss db_collection_cap TRANSACTION_LOG <10-50GB> command can be used from the command line.

Refer to Database Commands for more details.

The resize operation will impact the usage on the disk size allocated for the database (typically, 250GB is reserved upon installation). Consider a larger database disk size allocation upon installation if a larger cap size is set.

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.

For Memory and CPU, the Resource Allocation Reservation on VMware should correspond with these requirements.

Note

    Refer to the Upgrade Guide with ISO and Template or Installation Guide.
