A performance monitor reports SAN performance so that issues within the SAN are not masked from the client. Accesses to the SAN may be grouped into the categories of SAN logical or SAN physical. In one specific embodiment, the ranges of service times for accesses to the SAN are determined by monitoring service times of accesses to the SAN from the client perspective. In another specific embodiment, the ranges of service times for the SAN are determined by the SAN returning data with each request that indicates the service time from the SAN perspective. This allows reporting not only SAN logical and SAN physical accesses, but also allows reporting SAN service time. By specifying SAN service time, the client is able to better determine network delays. In yet another embodiment, information is returned by the SAN to indicate whether the access is SAN logical or SAN physical. |
