Why Virtualize
EDGE
Exchange
Aging, 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

After Virtualization
Virtualized Components
• Reduce physical servers
• Increase utilization
• Slash power/cooling bills
• Save rack space
• Provision servers faster
• Consolidate protection strategies

Customer Success: Sherweb
Exchange 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 weeks

First understand your workload including Background Database Maintenance
Protocol: Consider your requirements and choose accordingly
Disk: Most common for Exchange 2010 10K FC and 7.2K SATA RAID5 or 6
Formatting and alignment considerations – Windows 2008 is better
Consider thin provisioning for SAN deployments
Use the Microsoft Storage Calculator as a starting point
We walk you through how we design storage for Exchange
Use scalable building blocks: X users fit on Y disks.

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
Use Other Methods for Synchronous Replication, Virtualization-Centric Options

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.

Backup/restore speeds
First finalize your storage architecture.
Prioritize your backup and restore speeds (RPO, RTO).
Consider the costs and licensing options.
Try a layer of disk – there are much better options than tape.
Consider advanced options like deduplication and cloning.
