Typical Customer Requirements

Typical Customer Requirements

Small-to-medium businesses (SMBs) represent about 90 percent of all companies in the United States. These companies typically employ a few hundred employees and are highly focused on their core services or products. They usually lack IT expertise and manpower to develop, deploy, and maintain LAN, WAN, and SAN infrastructures. A typical SMB may have one or two offices in multiple metro areas with one head office (corporate office) in one of the metro areas. The corporate office is considered as the home office, where the majority of the business activities occur, and other locations are usually designated as satellite offices where most of the activities are directed to the home office.

These SMBs use IP connectivity to connect between satellite and home offices. Connectivity varies from Frame Relay, TI, and fractional Ethernet, depending on the demand and size of the SMB. Currently, these networks are used to carry data and voice traffic. A similar connectivity is considered for storage, but is not currently installed because of cost constraints. Most of the data at the home office location may be consolidated into a local SAN, and the data at the satellite offices can be consolidated into small SAN islands. This introduces the problem of storage connectivity between SAN islands for disaster recovery and business continuance. There are several options to interconnect the SAN, but the IP network is the ideal choice because of its availability at the client site and its comparatively low cost.

In most cases, the SMB customers have connectivity that is less than DS3 speed and, in some cases, may be up to OC-3 speeds. Therefore, in some cases, compressing the Fibre Channel data before transporting might become a requirement. In any network, security is key to protect valuable data from being misused by intruders. FCIP traffic must be secured before transporting it across the SP network.
