LeftHand Webcast Tomorrow

by Administrator on February 27, 2007

Just finished writing a piece about high availability Exchange hosting that will publish next week on ESJ.com.  It ties into a webcast I am doing on the subject tomorrow for ESJ’s publishing unit and Redmond Magazine.  If you have a moment, and are interested in email, drop into the webcast.  Details and registration are here.

Microsoft flirted with active-active clustering for Exchange, but performance issues saw them back away from the concept.  So, the world has basically seen HA hosting for Exchange provided via failover (active-passive) clustering for the last few years.  This model continues in Exchange 2007, despite the confusing foo about CCS, which I will touch on in my presentation and in the ESJ.com article. 

Most importantly, for a “shared nothing” clustering model, Exchange clustering still shares one inconsequential thing:  email data itself.  Huge vulnerability, that.  One that can be addressed elegantly by LeftHand Networks, and perhaps by grander schemes from CA (XOsoft), Neverfail Group, and Symantec — just to list a few. 

Have a listen and/or a read.
