Microsoft Office SharePoint Server 2007 supports the use of iSCSI connected disks as storage for the SharePoint Server and its associated data files.
For this installation, the disk drive letters “N”, “S” and “T” are all iSCSI target volumes allocated to server DMRTK-SRVR-B2, which is running Microsoft Windows Server 2003 R2 Enterprise x64 Edition. The iSCSI target volumes were created in the standard fashion described in other sections of this document.
The installation wizard prompts steps through the installation with minimal interaction from the user.
The Advanced installation option is chosen so that the iSCSI target device, drive letter “N”, can be used for the location of all the SharePoint programs and data. A stand-alone deployment will be performed.
After the configuration wizard finishes, the SharePoint default home page is displayed and SharePoint is ready to use.
Microsoft Exchange Server 2007
Microsoft Exchange Server 2007 can be deployed using an iSCSI storage solution. The basic requirements for storage for Exchange Server 2007 are that there is enough capacity, acceptable disk latency and response time, and enough disk throughput to meet service level agreements. The disk storage must be formatted using NTFS. Due to its 64-bit nature, increases in database cache and other improvements, transactional I/O requirements for Exchange Server 2007 have been reduced from previous releases.
Unlike previous versions of Exchange Server, network-attached storage is not supported in Exchange Server 2007. The only network-based storage transports supported for Exchange Server 2007 are iSCSI and Fibre Channel. In Microsoft test labs, iSCSI has been proven as a capable storage transport for Exchange Server. When high throughput is required, Microsoft recommends multiple network adapters and the use of MPIO.
Microsoft provides detailed deployment guides for Exchange Server 2007. These deployment guides include a major chapter on the planning of disk storage for Exchange Server and cover a variety of topics including storage capacity, storage technology, RAID selection, LUN sizes, storage validation (i.e. Jetstress), and more. These deployment guides are available at: http://www.microsoft.com/exchange. In addition, Microsoft has created the Exchange Solution Reviewed Program – Storage (ESRP), which is a Microsoft Exchange Server program designed to facilitate third-party storage testing and solution publishing for Exchange Server. Details about ESRP are available at: http://technet.microsoft.com/en-us/exchange/bb412164.aspx.
Prerequisites for Deployment
The following steps were completed on the server before installing Exchange Server 2007:
All updates applied to Windows 2003 Server R2 Enterprise x64 Edition
Domain controller functional level raised to Windows Server 2003 level
Server DMRTK-SRVR-B2 joined the DEMARTEK domain
Microsoft .NET Framework 2.0 installed on server
Microsoft .NET Framework 2.0 x64 HotFix KB926776 applied
Microsoft Windows PowerShell installed
iSCSI targets logged on as volumes “M” and “N”
Exchange Server 2007 Deployment
Exchange Server 2007 provides a wizard to perform the installation.
Steps 1, 2 and 3 had already been completed before the Exchange Server 2007 installation began. The wizard was launched, license agreement reviewed and installation choices made.
A “typical” installation was performed. The Exchange Server will be installed in the default location. The Exchange organization was given as “Demartek-Lab”. Outlook 2003 clients are available in this environment, so the public folder database will be created.
After providing the data needed, the wizard performed the Readiness Checks then performed the actual installation.
Update Rollup 1 for Exchange Server 2007 was applied, and then the Exchange Server Management Console was launched.
Clicking the “Mailbox” item in the left panel revealed the details of the Exchange storage groups.
A new storage group will be created on the iSCSI target devices. The logs will be placed on the “M” volume and the data store will be on the “N” volume.
The iSCSI Storage Group now appears with the First Storage Group.
A new mailbox database will be created and mounted on the “N” iSCSI target volume.
