Traditional NAS EnvironmentsChallenges• Silos of storage - Poor utilization• Heavy administrative burden• Administrative skills across

networking protocols

Solution• Server and storage consolidation• Multiprotocol filers for support of

mixed user environments – NFS, CIFS, HTTP

• Unified architecture and management skill set

• Single storage infrastructure for NAS, iSCSI and FC environments

Benefits• Reduced complexity• Server consolidation• Reduced administrative cost

Always bid SVC in open systems environments!




N series positioning with DS family products

•The IBM N series family products are optimal solutions for NAS, iSCSI and mixed (NAS and Fibre Channel) environments whereas the IBM DS family products are optimal solutions for pure Fiber Channel SAN environments

•N series systems should be proposed for NFS/CIFS (NAS) or iSCSI (IP SAN) attached storage

•N Series systems should be proposed where the advanced functions provide unique benefits and competitive advantage

•Solutions areas such as distributed remote locations (stores, branches) App/Dev, and Exchange are areas where N Series can provide unique value

•N series should be proposed when customers desire a unified storage system (single platform) that supports NAS, IP SAN and FC SAN

• A unified storage solution could be an N series system or DS system with an N Series Gateway

•The DS8000 or DS6000 should be proposed for System z and i environments

•N series should be proposed when most of the users and TBs will be read/written via NFS, CIFS or iSCSI, and they need fewer users or TBs for FC storage

•The DS family of products should be proposed when the customer requires high performance in Fibre Channel environments

•There are certain environments and workloads where N Series will meet and exceed the customers FC performance needs




Performance Considerations in FCP Environments• The following chart was extracted from the “N series Performance – Fibre Channel Environments”

white paper.

• This chart reveals an actual apples-to-apples performance comparison between DS4000 and N5500 products within an SPC-1 Benchmark configuration.
