What’s new in Exchange 2013, 2 Webcasts, and More!

Next week I’ll be on a couple of webcasts related to Exchange server protection:

In these webcasts, we will balance a solid blend of best practices content with information about some of our latest products.   I promise not to waste your time!

Webcast 1:  Introducing EMC AppSync: Advanced Application Protection Made Easy for VNX Platforms

In this webinar, we’ll describe how to setup a protection service catalog for any company and how easy EMC AppSync makes using snapshot and continuous data protection technology on a VNX storage array… As a bonus we will show a cool demo.

Sign up here.

Webcast 2: Protecting Exchange from Disaster: The Choices and Consequences

In this demo, we’ll explore the 3 common Exchange DR options available to customers with an advanced storage array like an EMC VNX.  One of the highlights is that I will be joined by independent Microsoft guru Brien Posey who has the low down on what’s new in Exchange 2013 related to storage and DR enhancements and describe how many things change in Exchange 2013 and how many things stay the same.  Oh, of course we will have a cool demo for this one too!

Revenge of the (SharePoint) BLOB and Backronyms

BLOBs stored in SQL databases can be horrific.  Oh, THOSE kind of BLOBs.    

I was on a call with a customer this week who said they were reaching SharePoint content database file size limits (100GB) and they needed to get data out of SQL Server – bad.

But first let’s take a quick step back.

What is a BLOB?   And What Is a Backronym?

A blob (alternately known as a binary large object, basic large object, BLOB, or BLOb) is a collection of binary data stored as a single entity in a database management system. Blobs are typically images, audio or other multimedia objects, though sometimes binary executable code is stored as a blob. Database support for blobs is not universal.

Blobs were originally just amorphous chunks of data invented by Jim Starkey at DEC, who describes them as “the thing that ate Cincinnati, Cleveland, or whatever”. Later, Terry McKiever, a marketing person for Apollo, felt that it needed to be an acronym and invented the backronym Basic Large Object. Then Informix invented an alternative backronym, Binary Large Object.  [Wikipedia]

Problems with BLOBs?

  • Pushes content database file size limits to max (100GB)
  • Poor performance for large files, especially write intensive
  • Large file upload time
  • Can’t easily & economically scale
  • Poor asset utilization SQL Servers

Microsoft says BLOBs are bad:

“Typically, as much as 80 percent of data for an enterprise-scale deployment of SharePoint Foundation consists of file-based data streams that are stored as BLOB data. These BLOB objects comprise data associated with SharePoint files. However, maintaining large quantities of BLOB data in a SQL Server database is a suboptimal use of SQL Server resources. You can achieve equal benefit at lower cost with equivalent efficiency by using an external data store to contain BLOB data.”    Source:

Up to 95% of your SharePoint  (stored in SQL content databases) is a BLOB!

The Solution: Get BLOBs out of SQL

Keep the metadata in, and get the BLOBs out!

This solution we’ve designed is perfect for those of you in that situation who may be reaching SharePoint content database size limits or if you just want to run things better and more efficiently.

You can easily get 90% of SharePoint content data out of SQL Server and onto less expensive tiers of disk.

Join us for a live webcast that will take you through exactly how it all works – on October 10th.

Please sign up today to learn more about it event if you can’t make it, you will still receive the recorded webcast after.

2 Great AppSync Exchange 2010 Single Item Restore Demos

Our friend Ernes Taljic from Presidio, launched the Presidio Technical Blog “Converging Clouds” with a post about EMC’s new replication management software EMC AppSync.

He also made two excellent videos that showcase virtualized Exchange 2010 Protection and Single Item Restore with RecoverPoint and VNX Snapshots – all managed by AppSync.

VNX Replication: Ask the Experts… Now!

For the next three weeks we’re inviting anyone and everyone to ask anything about data replication on an EMC VNX storage array.

This is part of our Ask the Experts Series on the EMC Community Network forums.

Possible topics:

  • Application considerations
  • Bandwidth considerations
  • Determining which replication product makes most sense to use
  • How virtualization can affect your configuration

The forum is open and ready for any of your questions!
