IBM System Storage™ N series – Unified Storage Solutions Simplification P DP RAID-DP™ • As disk drives get bigger traditional singleparity RAID technology offers protection from a single failed disk drive. • With modern larger disk media, the likelihood of an uncorrectable bit error is fairly high, since disk capacities have increased but bit error rates have stayed the same. • Designed to survive all 2 -disk failure scenarios • Essential for SATA drives but also applicable to FC drives • Protects better than single-parity RAID or RAID 0+1 • No performance penalty for industryleading protection • The expectation is that no other disk fails nor uncorrectable bit errors not occur during a read operation while reconstruction of the failed disk is still in progress. • If either event occurs during reconstruction, then some or all data contained in the RAID array or volume could be lost. • The ability of traditional single-parity RAID to protect data is being stretched beyond its limits.

IBM System Storage™ N series – Unified Storage Solutions IBM N Series vs. EMC § EMC’s primary strength is in it’s market leadership § EMC will work hard to get you to focus on performance § Know two questions to deflect the performance issue § Key N series Technologies EMC does NOT have: § Flex. Clone - space efficient copies of databases and volumes for test, dev, and QA § Performance Enhanced RAID 6 - for superior protection from a 2 disk failure § Single OS - across entire platform for reduced administration and training, and for consistent software functions § Snap. Manager - application aware integration tools for Oracle, Exchange, and SQL § True Multiprotocol - NAS, SAN, i. SCSI, and Archive storage solutions from a single platform © 2007 IBM Corporation
IBM System Storage™ N series – Unified Storage Solutions IBM N Series vs. HP § HP can’t simultaneously access FC and IP § HP requires “Forklift” upgrades, even within product families § HP has performance penalties for RAID 6 and Snapshots § HP NAS capability through WSS or Linux only § HP wants to focus on selling servers, with little focus on developing innovative storage technologies © 2007 IBM Corporation
IBM System Storage™ N series – Unified Storage Solutions Review questions • • The Snap. Restore function allows customers • To restore Snap. Shots (files or complete volumes) rapidly • To mirror source to target changes • To restore an entire SAP environment • To provide virtualized storage pools The key value of the N series is? • The flexibility to attach SAN devices via NAS, i. SCSI, and FC simultaneously • Price/performance and capacity • Rich set of software functionality • The ability to provide data retention and compliance applications Flex. Vol and Flex. Clone are examples of ? • Mirroring solutions • A standard offering and a priced option • 2 standard offerings • 2 priced offerings Metro. Cluster is the ability to • Provide multiple cluster nodes in an engineering scientific application • Virtualize storage in Cluster 1600 offering • Failover of system data from primary system to backup system • Failover large applications and Unix operating systems © 2007 IBM Corporation

IBM System Storage™ N series – Unified Storage Solutions Inconsistent Snapshot Functions DART has two different mechanisms for creating snapshots: NAS § Copy on first write technique–usual EMC three-I/O write penalty § Slow Restores–requires copying blocks back from Sav. Vol § License in base price and includes volume restore i. SCSI § File versioning technique (similar to WAFL snapshot) – Up to 2000 snapshots per LUN § i. SCSI also supports “writeable snapshots” § LUNs cannot exceed 2 TB Bitmap Production file system (PFS) Data Blocks Transactions bound for PFS Read PFS DB 0 Read PFS DB 1 Write over PFS DB 2 Write over PFS DB 5 Write over PFS DB 7 Write over PFS DB 8 Write over PFS DB 10 Read PFS DB 0 Read PFS 3 DB 0 DB 1 DB 2 DB 3 DB 4 DB 5 DB 6 DB 7 DB 8 DB 9 DB 10 DB 11 Sav.

IBM System Storage™ N series – Unified Storage Solutions HP EVA Strengths and Weaknesses § HP EVA Strengths – Innovative RAID virtualization technology (Vraid) allows LUNs to be virtualized over pooled disks – Demand-allocated virtual capacity free snapshots – Mix FC and “FATA” disks in same enclosure – Integrated management and configuration tools § HP EVA Weaknesses – No fast restore capability for snapshots – Demand-allocated snapshots silently dropped when out of space – High Availability with CAVA solution – complex, inefficient, inflexible off-box remote mirroring – Incomplete Disk Protection Utilization - No complete double-disk failure protection (i. e. RAID-DP) - Requires double the spare disk space using “distributed sparing” technique - Vraid defeats built-in disk load-balancing abilities – No upgrade path to or from any other HP array family – No Qo. S workload prioritization (such as Flex. Share) – No native multi-protocol support ( NAS or i. SCSI) – Command View EVA cannot manage any other HP storage array HP EVA 4000 HP EVA 6000 HP EVA 8000 © 2007 IBM Corporation
IBM System Storage™ N series – Unified Storage Solutions HDS Key Strengths and Weaknesses § Tagma. Store Strengths – Quality hardware and high performance – Virtualization within subsystem with Virtual Partition Manager – Ultra resilient, scalable architecture for high availability – Large cache and internal bandwidth supports high transaction workloads – Full line of remote replication solutions with Universal Replicator § Tagma. Store Weaknesses – No upgrade path from lower-tier products – Software quality not always up to hardware quality levels – Expensive virtualization app (Virtual Partition Manager) – Performance of copy-on-write snapshots, RAID-6 – Hitachi, Ltd. owns the design, HDS has limited control © 2007 IBM Corporation
