Abstract

As Fibre Channel becomes the key storage protocol of SAN (Storage Area Network), enterprises are increasingly deploying FC SANs in their data central. Meanwhile, organizations increasingly face an enormous influx of data that must be stored, protected, backed up and replicated for mitigating the risk of losing data. One of the best ways to achieve this goal is to deploy SAN extension based on CWDM(Coarse Wavelength Division Multiplexing). Availability is one of the key performance metrics for business continuity and disaster recovery and has to be well understood by IT departments when deploying SAN extension based on CWDM, for it determines accessibility to remotely located data sites. In this paper, several architecture of storage extension over CWDM is analyzed and the availability of this different storage extension architecture are calculated. Further more, two kinds of high availability storage extension architecture with 1:1 or 1:N protection is designed, and the availability of protection schema storage extension based on CWDM is calculated too.
