Guest post: Storage Loves Dynamic Memory

Hi, I’m Alex Miroshnichenko, chief technology officer of Virsto Software. One of the most exciting events of my summer was the announcement of Microsoft Windows Server 2008 R2 Service Pack 1 (SP1). Though still in beta, SP1’s stability has lived up to production standards in Virsto’s test labs. SP1 brings Dynamic Memory to Microsoft Hyper-V.  In practical terms, you should be able to run meaningfully more virtual machines on the same server hardware, since static memory limits are gone. Dynamic Memory also... [Lire la suite]

Public Folder Replication Changes in Exchange 2010 Sp1

Many of you who have migrated or are still migrating public folders from Exchange 2003 to Exchange 2007 or 2010 have run into replication failures due to property validation. This validation was first introduced in Exchange 2007, and I initially blogged about some those issues in this old post on EHLO. I later posted a script on my personal blog that fixes some of those problems, and described another troubleshooting technique here. While the validation was good in that it kept 'bad' items out of your shiny new public stores, the... [Lire la suite]

Parent memory reserve with dynamic memory

Most people I know who have spent a lot of time with Hyper-V have had the experience of accidentally taking too much memory away from the parent partition.  This happens when they start too many virtual machines – and all of a sudden the performance and responsiveness of the parent partition goes down significantly. The response from people who hit this is usually to stop the last virtual machine that they started, to reduce its memory, and then start it up again. This solution has worked in the past – but is no longer an... [Lire la suite]

Exchange Address Book Service Doesn't Work After Upgrading To 2010 SP1…

If you were using static RPC ports for Address Book service in 2010 RTM, you will notice that you can't connect to the address book after the SP1 upgrade. The issue is that the 2010 RTM way of assigning a static port for address book service has been changed in 2010 SP1. In 2010 RTM, the static port was assigned by editing the microsoft.exchange.addressbook.service.exe.config file in the Bin directory. In SP1 RTM, Exchange Product Group has moved this option to the registry, in line with assigning a static port for the RPC Client... [Lire la suite]

Guest Paging vs. Virtualization Paging and Negative Memory Availability

Jeff has discussed this at some length over on the virtualization team blog, but as a general rule of thumb we believe that it is much better to have paging occur inside the guest operating system rather than at the virtualization layer (if paging is needed). The simple reason for this is that the guest operating system has far better understanding of which are the best sections of memory to page out – where as all the virtualization layer can do is to guess at what should be paged out. In my recent demonstrations of dynamic... [Lire la suite]

Exchange 2010 SP1 Setup Error – MSExchange Transport Failed To Reach Status “Running” On This Server

Most exchange admins should be familiar with this error message by now. I ran a clean install of Exchange 2010 SP1 RTM, only to find this error message. MSExchange Transport failed to reach status “running” on this server. The cause is the same, as in previous versions. Check my previous article for more info. This happens when IPv6 is unchecked in the TCP/IP properties of the NIC, but not disabled fully in registry. This issue was fixed in the previous version rollups, but is now back with 2010 SP1 RTM. I checked IPv6... [Lire la suite]

Exchange 2010 SP1 and Blackberry Enterprise Server (BES)

Many will be upgrading to Exchange 2010 SP1 soon.  Many of you also have Blackberry Enterprise Server.  RIM has provided a pre-installation guide for Exchange 2010 here.  I wanted to touch on one of these pre-installation steps.  This is where we increase the maximum number of connections to the Address Book service.  The specific guide for this step is located here.  As you can see, you have to go into the following file “microsoft.exchange.addressbook.service.exe.config” and set MaxSessionsPerUser to...
