Industry Trends


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

Use the Microsoft Exchange Server Profile Analyzer to collect information from your current environment.

Example: • 1 physical location• 16,000 users• Mailbox profiles

• Average - 10 messages sent/40 received per day

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

Q: Should I Use DAS or SAN Storage?A: Either one will work.

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.


Dynamic Capacity Management using EMC Virtual Provisioning Functionality

DAS

In DAS world, people overbuy capacity

all the time

5000 Exchange usersx 5GB Mailboxes

SAN(EMC Virtual Provisioning)

Instead, buy the right size, and pay as you grow

with EMC’s virtual provisioning.

Hours/day

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

EMC’s RecoverPoint Replication Product• works in physical or virtual environments,

• replicates from any SAN to any SAN, • reduces bandwidth costs and usage by 5-10X

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.
