This document discusses techniques for extending the lifecycle of a Storage Area Network (SAN). It begins by providing context on IT spending breakdowns and the growth of the iSCSI market. Key considerations for network storage are then outlined, including price, reliability, scalability, performance, flexibility, and ease of management. Virtual storage approaches are presented as a way to lower costs, improve performance, and increase flexibility. Methods for extending the life of a SAN discussed include extended warranty options, hardware upgrades, firmware upgrades, ensuring performance and connectivity for future needs, and using volume virtualization. The document then profiles D-Link's xStack iSCSI SAN arrays and provides a case study of Luce Forward implementing a D-Link solution. It

5. IT Considerations
Price
 Total Cost of Ownership (Lifecycle)
What’s the order of
Reliability
 Redundancy and Fault Tolerance
importance?
 Data Availability
 Uptime & productivity
Scalability – grow capacity & performance over time
Performance
 Bandwidth vs. transactional
 Support multiple applications
Flexibility
 Repurpose resources as needed
 Eliminate pre-planning shortfalls
Ease of Management

6. Technology Briefing – Performance
Throughput – bandwidth (i.e. data pipe)
High bandwidth applications
 Disk backup/Archival
 Video & Surveillance
I/O – processing power
Transactional applications
 Database (SQL) and E-mail
 Virtualization
Drive performance
 SATA: High capacity, low cost, slower RPM (7200), single path
 SATA/SAS hybrid: High Capacity, medium cost, slower RPM (7200), dual path
 SAS: Lower capacity, higher cost, faster RPM (10K/15K), dual path

9. Virtual Storage Benefits (continued)
• Ability to configure any combination of volume types; no
need to make any global decisions up front
• Allows all of the available storage capacity to be utilized,
without any wasted space
• No need to pre-allocate drives to a specific storage pool
• Ability to re-configure any volume when needed; you are
not locked into anything
• All volumes are on-line during any grow or reconfigure
operation

10. Product Application – Storage Consolidation

11. Product Application – Virtualization

12. Product Application – Disaster Recovery

13. Extending the life of your SAN
• Extended warranty options
• Hardware upgrade as needed
– Add secondary controller as necessary
– Scalability beyond primary array as capacity needs dictate
• Availability of firmware upgrades
– Service, warranty or maintenance agreement required?
• Performance capability for future applications
– Transactional processing power to support upcoming applications
– Bandwidth available to support upcoming applications
• Available connectivity for planned infrastructure upgrades
– Massive data pipe for GbE networks
– 10GbE connectivity today w/ low-cost 10GbE uplink

14. Extending the life of your SAN (continued)
• Open architecture (grow capacity as needed)
– Support for non-proprietary, off-the-shelf disk drives
– Support for mixed drive environments
• SAS & SATA

– Scale performance with capacity
• Volume virtualization
– Eliminate need for RAID set containers
• Added flexibility for provisioning virtual volumes across disk pool
• Better capacity utilization
• Increased I/O performance
– Support volume reconfiguration on the fly
• Capacity expansion
• Reconfiguring RAID levels
• Migrating from physical disks
• Change stripe depth
