IT Efficiency Metrics

IT Efficiency Metrics
The clear answer to today’s IT challenges is to increase IT efficiency throughout the infrastructure, from the desktop to the data center. This Wiki is intended to provide a forum where efficiency metrics, goals and guidelines can be shared.

Storage and data management

Storage Strategy: Ethernet-Enabled

Storage and data management

GOAL: Ethernet-enabled connectivity

RATIONALE:  In the virtual era, an Ethernet-enabled structure is essential.
It provides the speed, ease of connectivity, and upgradability to 10G that will be necessary for scalable performance. y.

The emerging standard for network communications is Ethernet, using iSCSI for storage traffic.  The availability of storage arrays that use iSCSI has boosted the popularity of this storage  protocol. iSCSI will work over any Ethernet network, and can work in parallel with other network traffic, as long as the switches handling the traffic are able to assign the appropriate priority to the storage traffic.

Fibre Channel still persists in some legacy systems and its infrastructure is very similar to Ethernet’s.

POTENTIAL RESULTS:   Combining a legacy Fibre Channel storage network with a new iSCSI Ethernet network can be easy to accomplish and cost-effective for the economic life of the legacy system.  iSCSI storage has the additional benefit of running on the same Ethernet environment as other network traffi c. This means that there’s no learning curve as there is with Fibre Channel. The same network management software will work with storage traffic and other network traffic, and the same infrastructure, including switches and routers, can handle both types of traffic.
