Information for Partners about MediaSense Deployments
VM-Specific Cisco MediaSense Hardware Requirements
Before you install the Cisco MediaSense software in any server, you must address the following requirements:
- Only Cisco MediaSense must be running on this VM host. No other product can be installed on this server.
- If you are performing a fresh install of Cisco MediaSense in any deployment, be sure to verify that the virtual machine is also fresh (no previously-installed OS is present in the VM).
- On the C210 M1/M2 servers, MediaSense supports higher disk count and size than the disk count and size that is supported by the Tested Reference Configurations for the C210 M1/M2 servers, without requiring specs-based virtualization.
Cisco MediaSense-Specific Details for VMware Requirements
- Cisco UCS C-Series Servers, Cisco MediaSense ISO, and ESXi must be installed prior to the Cisco MediaSense installation.
- For other third-party software requirements and for a list of approved UCS servers, see the server requirements and version compatibility with Unified CM sections in the SRND for Cisco MediaSense.
Cisco MediaSense, Release 8.5(1) and 8.5(2)
All Cisco MediaSense servers run on VMs using the Unified Communications Operating System (Unified OS or UCOS).
- Cisco MediaSense only supports UCS C210 M1 and M2 servers for Release 8.5(1).
- If you are using ESXi 4.1, be sure to disable Large Receive Offload (LRO) on the ESXi 4.1 host.
Cisco MediaSense, Release 8.5(3)
|Note:||Cisco MediaSense has stringent requirements for the media disk size for any deployment. See the Solution Reference Network Design for Cisco MediaSense, Release 8.5(3) for more information.|
Up to 60 terabytes of media storage is supported per cluster, divided into up to six 2TB virtual disks in each of five servers. This assumes that all nodes are B-series servers, for which Cisco MediaSense supports SAN storage. C-series servers, for which only direct attached drives are currently supported, are limited to two 2TB media storage partitions each. Also, no single media partition may be smaller than 200GB.
See the following links for more information:
- See the IO Operations Per Second (IOPS)#Cisco_MediaSense section for the IOPS specifications
- See the Compatibility Matrix section in the Solution Reference Network Design for Cisco MediaSense, Release 8.5(3) guide for more information.
Cisco MediaSense, Release 8.5(4)
In addition to approved UCS servers, Cisco MediaSense 8.5(4) can also be installed on a Services Ready Engine (SRE) module inside a router. An SRE module is a router blade that has its own processors, storage, network interfaces, and memory. Support for SRE requires SRE v2.0 software. For more information about approved SRE models, see the Solution Reference Network Design for Cisco MediaSense, Release 8.5(4).
If you are using ESXi 5.0, make sure that you disable Large Receive Offload (LRO) on the ESXi 5.0 host.
Cisco MediaSense, Release 9.0(1)
Specification-based Virtualization enables Cisco MediaSense to run on Cisco Unified Computing System (Unified CS) servers that are also running other virtual machines. Specification-based Virtualization also enables Cisco MediaSense to run on select HP servers (Note that IBM servers are currently not supported.)
A new Open Virtualization Archive Virtual Machine (OVA-VM) template enables Cisco MediaSense to simplify the deployment of virtual machines in new installations. This template has deployment options for Services Ready Engines, primary servers, secondary servers, and expansion servers.
Cisco MediaSense-Specific Information for OVA Templates
If your partitions (VM disk configuration) are not aligned, your data replication between the primary and secondary servers may get congested and result in your data being out of sync. To avoid these problems, only use the VM templates provided by Cisco MediaSense.
See the following websites for more information:
- Unified Communications Virtualization Downloads (including OVA/OVF Templates).
- Cisco MediaSense OVA Templates
|Caution:||If your VM template or VM configuration does not meet the Cisco MediaSense requirements, it is possible for your installation to halt due to an unrecoverable error. See Installation: Installation halts with an unrecoverable error.|
Cisco MediaSense-Specific Information for Sizing Guidelines
The VM-specific sizing informaton required for Cisco MediaSense is additional virtual disks for media storage. See the SRND for Cisco MediaSense for further information.
