Most IT managers have read about the benefits of storage networks (iSCSI or Fibre Channel) to consolidate and share storage. Storage networking is also vital to building a cost-effective BC and DR plan. Storage consolidation centralizes resources, and storage networking ties them together so they can be migrated, replicated and protected without impacting production systems and to support SLAs. Storage networking links storage islands inside data centers, remote sites and hot sites. Storage networking and consolidation for BC and DR provide several other key advantages:
- Single Storage Protection Policy — Consolidated storage is the key to building a solid and sustainable BC and DR plan. It enables IT mangers to build a single set of data protection policies and have them executed in a unified fashion. When the storage is centralized it is easier to support SLAs with a single plan, it is easier to manage and easier to validate BC and DR plans.
- Rapid Restore for SLAs — Storage networking, combined with disk-based backup, is vital to meet SLAs (that are often under one agreement) for business-critical applications such as transaction systems, web sites and email.
- Off-site DR — Again, the combination of storage networking and disk-based backup are vital to provide off-site DR and BC capabilities. The limited bandwidth of telecommunication lines require high performance and low latency storage for maximizing the use of expensive telco lines and to ensure synchronous communications.
- Regulatory Requirements — Almost every business has regulatory requirements related to data protection, security and application availability. For any public company and many companies that supply government agencies, BC and DR plans are requirements. The partnership of storage networking and storage consolidation provides the tools required to share and replicate data locally and over distances.
