Why VirtualizeAging, Physical Infrastructures
• Inefficient Servers– Inefficient processor types– Putting out too many BTU’s– Excess power/cooling
• Inefficient Management– Slow provisioning– Separate tools
• Inefficient Disaster Recovery
– Inconsistent backup/DR– Separate tools
• High Cost of Ownership

Customer Success: SherwebExchange 2010 Hosting Provider
• Challenge– Providing mail services for 60,000 users while keeping management
of a large scale storage infrastructure under control– Competition offering large mailboxes (20 – 30GB) for lower cost
• Solution– EMC Consultant analyzed environment and provided a
recommendation based on EMC Proven Solutions testing results and TCO analysis over 5 years
– EMC CLARiiON CX4-480, SATA, Thin Provisioning, DAGs
• Benefits– EMC CLARiiON CX4-480 scales to nearly one petabyte of capacity– EMC CLARiiON with 2TB SATA drives offer competitive cost per
mailbox– Thin Provisioning technology allows customer to “pay as they
grow” instead of overpaying for storage upfront– Virtual servers can be deployed in hours instead of weeksFor more information please visit: www.emc.com/exchange

1. First understand your workload including Background Database Maintenance 2. Protocol: Consider your requirements and choose accordingly3. Disk: Most common for Exchange 2010 10K FC and 7.2K SATA RAID5 or 64. Formatting and alignment considerations – Windows 2008 is better5. Consider thin provisioning for SAN deployments6. Use the Microsoft Storage Calculator as a starting point7. We walk you through how we design storage for Exchange8. Use scalable building blocks: X users fit on Y disks.

1. DAG’s are a good technology, but not perfect• Requires high degree of Exchange knowledge• WAN Link Challenges and costs for DAG replication and RTO’s• Can be costly: 3 Copies minimum, Enterprise edition required• Host/network usage and reseeds can be an issue – careful planning needed
2. Use Other Methods for Synchronous Replication, Virtualization-Centric Options• Exchange 2010 Synchronous API (EMC unique)• DAG’s use storage block-level replication technology instead of log shipping!• EMC RecoverPoint (Bandwidth reduction, multi-app, continuous replication)• Virtualization Centric options provides standardized virtual machine DR

Q: Do we still need backups?A: Yes, most likely.
Why backups?
DAG logs need to be truncated.Operational and long-term restores.
Retain your existing processes.Corruption, viruses, human error.
1. First finalize your storage architecture.2. Prioritize your backup and restore speeds (RPO, RTO). 3. Consider the costs and licensing options.4. Try a layer of disk – there are much better options than tape.5. Consider advanced options like deduplication and cloning.
