The Value and Evolution of SAN
Nishan Systems Confidential
Value of Storage Area Networking
5
•
Storage Consolidation
– Reduce administrative overhead – Maximize storage utilization
•
High Availability
– Server clusters accessing shared storage – Mirroring terabytes of data/common accessibility
•
Disaster Recovery / Metro and Campus
– Remote mirroring within the SAN – Tape backup / restore

Evolution of Storage Area Networking IP SANs
● Based on mainstream TCP/IP networks ● Enables SAN over WAN ● More robust features; scalability ● Standards-based (IETF, IEEE, ANSI)
Fibre Channel Switched Fabrics
● Data Center / Departmental SANs; many devices ● Dedicated Bandwidth per port vs. shared bandwidth
Fibre Channel Arbitrated Loop
● Small departmental SANs; small number of devices ● Shared bandwidth
VAX Clusters / IBM ESCON / SSA
● Proprietary shared storage solutions ● Superceded by Open Systems FC

Fibre Channel SAN Issues - Extensibility
Native FC can not be transported over most service providers infrastructure.
Wide area networks are based on IP or Ethernet and not FC, therefore, costly point-to-point Dark Fiber or DWDM is required to connect FC SAN .

Fibre Channel Networks are designed for “intra data center” environments
– Not architected with distance or latency in mind – Enforce strict reliability and performance requirements – Homogeneous FC-2 Transport

Fibre Length (Km)
250 300 350 400
Limited credits of FC switches causes a dramatic decrease in utilization > 30km Can increase distance by robbing FC credits from other ports Disadvantages:
– Lost switch port density – Doesn’t fix link-utilization problem (just delays it) – Still have FC scalability limits if connecting FC-switches (few as 8 switches in fabric) – Service not available in all regions
Best positioned between limited FC Targets (2) that are relatively close, and where availability and tariffs not an issue Nishan Systems Confidential

Compression & Jumbo Frames
• •
Compression
– Up to 11:1 Compression Ratios – Standard Compression algorithms with extensions – “Smart” Compression - compresses just enough to match egress data rate to port speed – Both ends of a connection NEED NOT turn on compression to realize gains
Jumbo Frames
– Support for maximum size FC frames - payloads up to 2048 bytes – Jumbo frame support should be end-to-end in the network – The IPS switches can handle incoming jumbo frames even if the support is not turned on.
– Better overall throughput • Reduced header overhead • Higher traffic rates = higher gains • Compression works better due to bigger sized payload
