EMC’s Exchange Positioning The Position: Promises to simplify, improve productivity, cost savings,and deployment of Exchange Server 2003 via networked storagesolutions with a tiered storage approach and service level optionsto manage the information lifecycle of a customer’s Exchange environment.
EMC Exchange Sales Pitch and Tactics • EMC Sales/Marketing Pitch • Microsoft uses EMC storage for their Exchange environment • Long-term Microsoft partnership • If you can’t beat NetApp value – give it away! Well Almost… • Reality • EMC solutions require over 70% more disk capacity than NetApp to provide near-same data protection levels • Mixed RAID offering only - no double parity RAID – limited data protection • Extensive Professional Services required throughout • All EMC recovery solutions are limited to Clones only – in most scenarios • Not listed in MS Exchange solution Reviewed Program (ESRP) for Storage
EMC Exchange Offerings Note: EMC array options include CLARiiON, Symmetrix, Celerra, and Centera • SnapView Integration Module for Exchange • Simplified, non-disruptive backup and automated recovery for CLARiiON • TimeFinder Exchange Integration Module (TEIM) • Simplified, non-disruptive backup and recovery for DMX • EMC Replication Manager (ERM) (CLARiiON, Celerra, DMX) • Automated management of disk-based replicas for applications running on Windows Server 2003, including Oracle and SQL Server • GeoSpan (DMX) • Geographically dispersed cluster solution integrated between MSCS and Symmetrix Remote Data Facility (SRDF) • VisualSRM (storage independent) • File-level monitoring, reporting, and browsing with drill-down, and folderwalking for all Exchange, Oracle, SQL, and SAP applications - can be used to locate PST issues; remind users of local PST policies, and delete them if required • NetWorker PowerSnap (storage independent) • Policy-based management to administer snapshots in NetWorker, schedule, create, retain, and delete snapshots by policy for Exchange, Oracle, SQL, and SAP • EmailXtender, EmailXaminer base/Archive Edition (storage independent) • Oracle backup, archive, text search, monitoring and compliance insurance • EMC Centera (content addressed storage) • Content authenticity for e-mail archive data cost effectively and intelligently managing all Exchange information from creation to archiving and disposal
EMC ILM and Microsoft Exchange EMC SLIDE
Eases Exchange Migration Reduces Exchange migration time Simplifies Exchange Storage Administration Focus on managing Exchange, not storage Recovers Quickly from Exchange server failures A lower-cost alternative to clustering EMC Storage Administrator for Exchange Limited Features - long on Sales & Marketing Spin $715 USD (AX version) Exchange plug-in that consolidates storage on CLARiiON arrays hosting up to 3,000 mailboxes *Storage Administrator/Exchange base pricing for AX100 as of April 28, 2006. NOT 3,000 mailboxes
Replica1 Replica2 Replica3 Replica4 Exchange on EMC DMX, CX, AX, NS, NSX, … EMC Replication Manager/SE Replication-management solution leveraging Microsoft’s VSS (Volume Shadowcopy Services) technology for CLARiiONusers with SnapView & SAN Copy in Windows environments – Max 8 clones/snapshots per array EMC Replication Manager/SE for Celerra Yet another replication-management solution leveraging Microsoft's VSS technology for Celerra users with Celerra SnapSure iSCSI EMC Replication Manager/Local Ditto… but for Symmetrix DMX users via TimeFinder, SnapView replicas, SAN Copy, HP StorageWorks clones, and Microsoft’s VSS with rapid backup and restore; no impact to production server – Max 8 clones/snapshots per array Note: Clone - 100% copy of source LUN, Snapshot - 15-20% of source LUN, Replica (snapshot or clone, read/writeable)

QUESTIONS TO ASK EMC EMC FUD: EMC says their clones are safer and more complete because they are 100% copies on separate disks Q. Why such small RAID groups? i.e. RAID 1/0 (3+3) and RAID 5 (4+1) A. More disk in a RAID group = higher risk there will be loss of data Q. What is the performance impact using SnapView to create copies of Exchange logs and checkpoints? A. COFW will occur (as required) once every sixteen 4KB writes resulting in transactions: • Taking 3-4 times as long • Reducing performance by 15-20%. • Typical Exchange environments with 33% writes and 67% reads can decrease performance to 40% per “EMC CLARiiON Storage Solutions Microsoft Exchange 2003 Best Practices – Storage Configuration Guidelines”
QUESTIONS TO ASK EMC Q. What impact does MirrorView/S (synchronous) array to array replication have on CLARiiON arrays? A. 50% degradation in performance for CX500 and 25% degradation in performance for CX700 – do the math… Q. How does EMC tune Exchange for performance? A. It’s all about sacrifices or that is: EMC Best Practices • RAID1/0 for performance = loss of 50% usable capacity • RAID1/0 = two physical I/O operations for each write (1 write to each mirrored disk - penalty of two • RAID 5 for large mailboxes and/or lower IOPS • RAID5 = four physical I/O operations for each write (2 reads to calc parity, one write for data, and one write for parity) per “EMC CLARiiON Storage Solutions Microsoft Exchange 2003 Best Practices – Storage Configuration Guidelines”
Notable EMC Best Practices for Exchange • Configuring metaLUNs • Can add a level of complexity to an Exchange design • It is possible to overuse metaLUNs(whatever happened to “Simplifying Exchange” ?) • Snap-based replication is not an ideal backup method to use with Exchange for the following reasons: • COFW must be completed before allowing change to production data… • Avoid configuring Exchange database LUNs on the CLARiiON PSM (drives 0-2 of the first 5 OS drives)(drives 0-4 are for low I/O activity only) per “EMC CLARiiON Storage Solutions Microsoft Exchange 2003 Best Practices – Storage Configuration Guidelines” Pages 18, 22, and 25

NetApp win over EMC (and HP) at Google • Head-to-head competitive evaluation (same data center) • EMC CLARiiON, HP EVA, NetApp FAS3050 • Brutal (and excruciating) evaluation criteria dreamed up by an EMC biased regional consulting firm • We came in LAST (found out late) and had to catch up • We won!
A few details… • 4-node Win/Exch 2003 MSCS Exchange cluster, FCP, SnapMirror between two FAS3050c’s (DR) • Performance (lots), management, DR failover and failback • Why we won: • EMC could NOT complete the evaluation tasks and had to “re-tool” between every test • We “turned it on” and ran through the series of test in a real-world fashion (we were the only vendor that could get it done) • Relationship (improved as we went) helped Questions: jp@netapp.com
