The Value andEvolutionof SAN


Value of storage area networking
Value of Storage Area Networking

SAN

  • 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
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● Superceded by Open Systems FC

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)

  • 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

Compression jumbo frames
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
