Value of Storage Area Networking

•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VAX Clusters / IBM ESCON / SSA● Proprietary shared storage solutions● Superceded by Open Systems FC

• 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– 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

Carlson Companies - World’s Largest IP SAN www.carlson.com

• Carlson Companies implemented a distributed IP SAN in order to:– Storage network 10 TB of disk for a data warehouse– Support multi-customer storage service level agreements via

flexible bandwidth management – Efficiently access remote site for disaster recovery– Implement centralized backup to the central data center– Integrate new native IP devices like iSCSI HBAs

“By moving storage data to our IP network, we can meet both our data

center and wide-area storage requirements and seamlessly integrate new

storage technologies such as iSCSI.” Steve Brown, Carlson CIO / Sr. VP

– Data migration from an EMC Symmetrix to a Lightning 9960 via VERITAS software locally

– Then Hitachi TrueCopy via a Nishan switch to a remote Lightning 9960– During test, link was broken and re-established – pairs re-synched

• Results– Exchange server data was migrated– Server was relocated to target location– Data was verified and server activated
