Recorded minutes in MR =13,200 minutes/day * 21 days/month * 2 months = 554,400
min
Voice Storage = 554,400 minutes * 0.12 MBytes/minute = 66 GBytes
Screen Storage = 554,400 minutes * 1.2 MBytes/minute = 665 GBytes
Note: A single system may have multiple groups of recorded users with variations in recording
rules or retention periods so this calculation may need to be repeated for each group and the
results summed together to get to total storage requirements.
5.4.7 Recorded Contact Storage Calculator
A spreadsheet to assist in calculating storage requirements is embedded below and is also
available as a separate .xls file from the Calabrio partner portal at:

5.4.8 Options for Recorded Contact Storage
MR supports a variety of contact storage options including local hard disk drive (HDD), network
attached storage (NAS) or storage area networks (SAN) by allowing the installer to specify the
storage location for voice and screen recordings as server and pathname during install or change
the location by moving the existing contacts and running the post-install process to specify the
new contact storage location. It is recommended to use external enterprise-class SAN or NAS
storage for critical recordings because of the additional fault tolerant options provides by these
storage architectures.
5.4.8.1 Local Storage
Contact storage can be hosted within the MR single server or on the Voice and Screen Storage
servers in the multi-server configuration. The storage used can either be a portion of the server’s
primary partition on the base disk(s) that came with the server or can be on a secondary partition
using additional drives added to the base server. In either case, it is recommended that contact
storage be provided on a RAID volume to protect the recorded contacts from drive failure. The
following table shows the base and expansion capacity of the Cisco MSC server configurations
recommended for MR deployments. It is from a worksheet within the storage calculator
worksheet described previously.
