摘 要：
Datacenters with multiple SAN implementations today will find two advances in SAN technology important and useful. These will enable next-generation datacenter SANs to further consolidate storage and improve manageability.
IDC believes that consolidation can take can take place in the storage network fabric as well as in storage arrays. For example, multilevel multi-protocol switches with higher port counts can consolidate the switching function within the SAN, as well as offer end users an alternative to separate, purpose built bridging devices. Consolidation may also occur through the use of larger switches, i.e., switches with increase port density. Using larger building blocks within the SAN will result in fewer switches and also reduce the number of ports needed for inter-switch communications.
Manageability will improve due to advances in storage and network virtualization, the technique of mapping physical characteristics of devices to logical attributes that are simpler for operators to manage. IDC believes that standards play an important role in advancing such virtualization within the multi-vendor world of enterprise SANs.
Co-operative development efforts at the Storage Network Industry Association (SNIA) are expected to ultimately generate an industry standard vocabulary that becomes the basis for cross-vendor virtualization efforts.
