MCS Server Recording Storage Capacity

Base Capacity

To calculate actual expansion capacity of servers fill in the yellow highlighted cells,

default values show the maximum potential capacity

Notes:

The MCS 7835 provides the maximum expansion capacity for recording storage.

Popular expansion 2.5” drive capacities can be selected via a drop down in the Disk Capacity

column.

MCS 7816 base only provides a single 160 GB disk with no RAID protection for the primary

partition. It is recommended that disk expansion be done with an equivalent disk capacity,

binding the expansion drive to the base disk in a RAID 1 volume.

The base reserved system capacity is an estimate of the space required for the OS, database and

MR server application and may need to be adjusted for the actual server configuration.

5.4.8.2 Network Attached Storage or Shares

Configure the NAS or share to allow read and write access from the MR server and allocated the

required storage capacity to the share. Set the server and storage share location during MR

install to the server name and share to be utilized.

5.4.8.3 Storage Area Network (SAN)

Map a dedicated SAN volume to the MR server and create a file system partition on that volume.

Then setup the recording storage to point to the mapped drive or a share name within the

partition

5.4.9 Quality Management Backup CTI Services

QM 2.7 introduced a Backup MR CTI service option to provide redundancy for the

communications path for CTI events like ringing, answered, dropped between the Cisco Unified

Communications Manager, CUCM and the MR endpoint or Server based recording services. A

backup MR CTI service would be required for each primary MR CTI service, one of which is

required for every CUCM cluster covering recorded users.
