10 Solution Architecture Physical architecture Figure 1 shows the overall physical architecture of Virtualized Exchange 2007 Journaling and Archiving with EX-DX to EMC Centera. The solution has four stackable modules: consolidate, backup, archive, and protect. The solutions outlined in this reference architecture are for a proven solution of archiving that uses the following: Tested building blocks for a fundamental base Exchange 2007 mailbox server EMC Xtender and DiskXtender for archiving in a two-stage approach by utilizing an EMC CLARiiON CX3-20 and EMC Centera A VMware ESX 3.5 Server was used for consolidation of hardware for a low-cost solution. Although it still has the ability to home a midsize enterprise level of mailboxes, this solution will also work in physical environments requiring individual server hardware for every VMware guest. The Exchange 2007 was set up having journaling on the Hub / Cas. The Exchange 2007 server along with Xtender was used for archiving the journal mailbox from a RAID 10 drive to a RAID 5. For the second-stage archive, DiskXtender was used along with an EMC Centera disk library that showed compliance capabilities with the Xtender/DiskXtender. The Xtender /DiskXtender was used for mailboxes archiving in the same two-stage approach, allowing for archiving of at set date thresholds. This reduces the database footprint on the mailbox servers. Reducing the footprint allows for faster streaming backups, clones, or snaps, which in turn allows for faster recovery of databases if required. Note: Figure 1 shows the CX3-20 diagram. 10 EMC Solutions for Microsoft Exchange 2007 Virtualized Exchange 2007 Archiving with EX-DX to EMC Centera

11 Solution Architecture Figure 1 Physical architecture of Virtualized Exchange 2007 Archiving with EX-DX to EMC Centera Network architecture The network architecture discussed in this reference architecture focuses on two areas: Virtualization using VMware ESX 3.5, and iscsi technology. iscsi technology is a blossoming technology allowing customers to connect to storage arrays utilizing existing Ethernet networks as an ideal fit. iscsi works best with low bandwidth, high I/O. Exchange of small I/O (a size of 8K for Exchange 2007) means iscsi can scale to tens of thousands of users simply by using GbE NICs and the Microsoft Software Initiator. Virtualization is an upcoming technology that can be used for consolidated usage of hardware along with high availability using VMware technologies within the ESX Server such as VMotion, DRS, and VMHA.

12 Solution Architecture A CLARiiON CX3-20 using Microsoft iscsi Initiator on the hosts, along with EMC s PowerPath software in an interconnect SP design, allows for multiple paths and fault tolerance in the event of a SP failure. Note: Figure 2 shows the iscsi connection ports for the CX3-20. Figure 2 iscsi connection ports for CX3-20 Note: Figure 3 shows the Microsoft iscsi Initiator configuration.

13 Solution Architecture Microsoft Exchange Server architecture Storage architecture The Microsoft Exchange Server 2007 (refer to Figure 1) represents a stand-alone configuration using Microsoft Windows 64-bit Microsoft Windows 2003 Enterprise Edition SP2, Exchange 2007 Enterprise Edition installed for messaging with PowerPath bit, Microsoft iscsi bit, and Navisphere Agent/CLI bit installed for storage array access using iscsi. After the installation of Exchange, it is highly recommended to run the Microsoft Best Practices Analyzer. In the current setup, Microsoft Best Practices Analyzer is installed with Exchange 2007, following all recommendations for performance tuning and hotfix installation found in the Exchange Management Console (EMC). The Exchange Server has external storage assigned. The server is connected to the external storage through iscsi connections. These connections are created using Microsoft iscsi Initiator Note: For instructions on the configuration and setup of the iscsi targets please refer to EMC Solutions for Microsoft Exchange 2007 CLARiiON CX3 Series iscsi - Best Practices Planning An EMC CLARiiON CX3-20 provides external storage to the Exchange Server. The Exchange message stores and logs are accessed through the assigned ports logged in through the Microsoft iscsi Initiator. Service processor failover of LUNs is available through PowerPath 5.0. The storage architecture is based on a new design utilizing building blocks. This design builds upon itself as customers grow and require additional space and fault tolerance. The building blocks guarantee performance and minimize design and operations complexity in increments of four-disk RAID 10 building blocks, with a 0.42 user I/O profile and maximum mailbox size of 270 MB. RAID 10 supports high fault tolerance and performance levels with the least amount of disks and the maximum number of users. Thorough testing proves that the design approach using building blocks provides exceptional performance. Building blocks Consolidate The building blocks 1 design is set up using four Exchange storage groups, one database per storage group. For the databases, a four-drive (300 GB/15,000 rpm FC) RAID1_0 RAID group will be created, and four LUNs of 120 GB will be created within each of the newly-created RAID groups. The RAID group is created for the log file LUNs in a four-drive (300 GB/15,000 rpm FC) RAID1_0 RAID group and four LUNs of 12 GB will be created within the newly-created RAID group.

14 Solution Architecture The databases will be placed onto the corresponding LUNs (drive or mount point) created on the 120 GB LUNs. Log files will be placed onto the corresponding 12 GB LUN (drive or mount point) along with a LUN created to home the VMware datastores that hold the boot file (VMDK) for the Exchange 2007 operating system. Note: Figure 4 shows the drive layout. Figure 4 Drive layout Archive The archive configuration was set up using RAID 1_0 2+2 for quorum, journal database, and log files for Xtender. The same RAID configuration was used for the Container, Index files, MSGCenter, and MSMQ SQL files. RAID 10 was chosen for fast access during archiving and fault tolerance. Xtender was configured in a MSCS configuration as a best practice to ensure that, in the event of hardware failure or maintenance, users can have access to the archived . VMware VMware guests were configured on the CLARiiON in a RAID 5 configuration for fast reads during boot and to maximize space for the VMDK (boot) files for the reference architecture guests described in this solution. 14 EMC Solutions for Microsoft Exchange 2007 Virtualized Exchange 2007 Archiving with EX-DX to EMC Centera
