Future Initiatives
Going forward, the team explains that they will concentrate on fulfilling the vision of enterprise networked storage offered as a utility for their clients. Integral to the success of the storage vision is the upgrade of the IP network backbone and the ongoing evaluation of both hardware and software replication technologies to augment business continuance capabilities.As mentioned earlier, with the addition of the IP Storage Services Modules to the Cisco MDS 9509 multi-service switches, the team has already begun to use FCIP between the primary and secondary datacenters. The long-term goal is to replicate the critical production data to the disaster recovery site as quickly as possible to minimize the amount of time that production data is available only at the primary site. To that end, the team states that they want to implement a disk-staging strategy utilizing FCIP between the two locations.Because prices for fiber remain competitive, the team is willing to look at adding more fiber between the primary and secondary sites; however, the team believes eventually it will choose to implement either Course Wave Division Multiplexing (CWDM) or Dense Wave Division Multiplexing (DWDM) (or a hybrid of the two technologies) to optimize the bandwidth between the production and disaster recovery sites. In the interim, the team plans to continue using FCIP over the IP backbone.The continued migration of UNIX applications to the Linux platform is another highly visible project, as is further testing of iSCSI on the IP Storage Services Module, and the deployment of blade servers directly onto the SAN configured to boot over Fibre Channel. The team has also evaluated networked-attached storage but currently sees no need for NAS in the environment.
