Business Case for Shared LAN Cache

Enhances Productivity

Shared LAN Cache enhances productivity by reducing the time it takes for PC users to access large files across LANs and WANs. Application software, imaging, electronic faxes and other data files are automatically cached, significantly improving access times to these files.

Caching redundant read requests for data also off-loads the network for other applications and users that require access to the existing file servers. This improves network response time for users writing data to the file servers further enhancing user productivity.

Saves Money

In addition to the savings realized through enhanced user productivity, SLC also saves money by deferring the large capital expenditures required to upgrade LANs and WANs. Wiring, file servers and workstation hardware upgrades can be made over time as higher performance technologies gradually become less expensive. SLC also extends the life of the latest state-of-the-art LAN and WAN equipment by using the enhanced bandwidth more efficiently.

Cost Effective Upgrade

SLC is the single most cost effective upgrade available to enhance network performance. The cost of upgrading to SLC is only 10% of the cost of upgrading network nodes to 100M. SLC also off-loads existing file servers and improves WAN performance. Compared to hardware upgrades which can take weeks and months to deploy, SLC can be up and running on an entire network in less than an hour.

Upgrading network nodes to 100M technology without SLC adds an extra load on the existing file servers and may negate much of the performance gains sought by upgrading to 100M hardware. Combining SLC with 100M technology allows users to achieve the highest possible performance.
