Email – it’s worse than heroin..??!!

“The average corporate user generates and receives about 84 e-mails per day which require about 10 MB of storage on a daily basis. And by 2008, e-mails will require about 15.8 MB of space daily.”

- Radicati Group, 2006

• Email now mission critical• Ubiquitous & increasingly mobile• Encourages bad practice..?

– Information overload– Use as a file share– Users “Hide behind email”

Trends in email deployment• Consolidation & Centralisation

– Clustering, server scalability, pervasive reliable bandwidth, Outlook cached mode

– Commoditisation of storage technology• Role of Disaster Recovery

– Cost of backup/DR reducing (from Ex2003)– Requirements for site resilience increasing

• Flexible Working for end-users– Easy remote access now the norm– Mobility, voice integration

Enterprise Topology

Messaging at Microsoft• 3 Locations worldwide – US, EMEA, APAC• 16.5m msgs/day arrive from the internet

(115m/week)– 12.6m filtered as spam by Connection Filtering– 350,000 messages were rejected by the IMF – ~66,000 messages were routed to user Junk Email Folders

• 1.3m messages were delivered to user Inboxes– 91.92% spam– 2.4 million internal messages received– 2.5 million internal messages sent

• Moving to 2Gb mailbox quota for everyonehttp://www.microsoft.com/itshowcase

Edge Spec• 6 servers handling inbound internet traffic and the

majority of our outbound traffic for ~130K MBX’s• 4 servers in regional locations

– (2 in Dublin and 2 in Singapore). • 10 x: 2 dual core 2.2 GHz proc with 8GB RAM. • 6 spindles

– 2 spindle mirror for OS, page file, and transaction logs– 4 spindle raid 10 which contains the transport database

along with message tracking and protocol logs.

Impact of 64 Bit “Storage makes up roughly 40% of our hardware cost for Exchange today. Because of the 64-bit optimizations in Exchange 2007 we are able to get the performance and stability needed out of a low cost iSCSI solution. With a full deployment we anticipate saving 30% on storage with Exchange Server 2007.” - Petr Grachev, CIO, SOK Group

“With the 32-bit systems in place today, we are only able to use approximately 20 per cent of the space on our storage area networks. We expect the move to 64-bit server to increase utilization significantly, resulting in tremendous cost savings”

- Dan Wills, Vice President of Operations, USA.NET Inc.

Jon Minnik Manager Technical Develop SE&A Siemens

“64-bit will facilitate further cost improvements meeting our needs for greater number of users/server, larger inboxes, increased user local stores, and most importantly enhanced security.”

64 Bit – Example

Here’s my rough and dirty “point making” exercise (it’s full of technical pitfalls, but makes the point)

Ex2003:– 900MB x 1024 = 921,600KB– 921,600 \ 1900 users = 485KB per user

Ex2007: – (32GB x 1024) x 1024 = 33,554,432KB– 33,554,432 \ 1900 users (like for like) = 17,660KB or

17MB per user

Your users CAN have a bigger mailbox• Exchange 2007 uses storage less intensively

– IOPS requirements lower, shared storage not required– Therefore, you can store more data online for the same ££

• Backups no longer a bottleneck– Replication means there’s another copy (or copies) nearby– Snapshot technology (VSS) more mature, less expensive

• Content management– Get rid of stuff you don’t need, keep online the stuff you

do• Everyone’s got a PST nightmare...

Reducing TCO @ Microsoft• $5 million a year savings on high availability

– Cluster Continuous Replication replaces tape backups

• 50% reduction in storage costs with 64-bit• 10 fold increase in user’s quota• User migration in a quarter of the time

“Cluster Continuous Replication allows us to maintain our high service level agreements on lower cost hardware, removes our dependency on expensive tape backups and eliminates the single point of failure.

It’s availability based on software, not dependent on hardware.”– Kyryl Perederiy, Senior Systems Engineer, Microsoft IT
