BUSINESS CONTINUITYGalaxy and Backup Exec include Exchange suites that are particularlytailored to Dell-based environments.For point-in-time copies, EMC ® SnapView software offers anarray-based snapshot approach that comes as an option with theDell/EMC product line. SnapView enables administrators to createmultiple, space-efficient point-in-time snapshots or addressablebusiness continuity volumes of Exchange data. This approachenables administrators to keep several snapshots from the sameday on rotation for recovery purposes.Legato ®PowerSnapsoftware enables strong support for hetero-geneous storage environments that use a variety of snapshot technologies.PowerSnap provides a common and open managementframework that allows administrators to manage snapshots acrossvarious applications, operating systems, and storage platforms.Gain application and server availability with clusteringAdministrators can implement Microsoft Cluster Service, a standardWindows-based clustering product, on Dell platforms. Dell providesthe option of using SCSI or Fibre Channel (FC) storage on theback end, making clustering a viable approach for both small andmidsize enterprises.Protect the site with remote replicationDell offers remote data replication software to help protectExchange environments. For example, EMC SAN Copy softwareprovides an array-based approach to data movement that allowsdata to be replicated between Dell/EMC arrays at the same siteor between remote sites. Data can be replicated using FC andFC over IP. EMC Replication Manager SE (RMSE) serves as themanagement interface, giving administrators a single point of controlfor local and remote replication operations. Using RMSE andSAN Copy, administrators can replicate a copy of the Exchangedatabase and log files created by Microsoft Volume Shadow CopyService (VSS) to a secondary disk array. The use of VSS helpsensure that a consistent point-in-time copy of Exchange is takenand replicated for extended business continuity.EMC RepliStor ® software provides an asynchronous, file-basedapproach to replication that can be configured to copy data fromsource to target systems (and vice versa) across a LAN, metropolitanarea network (MAN), or wide area network (WAN). RepliStor runsdirectly on a server platform and allows clients to be redirected toaccess data from the target in the event of a failure at the source.RepliStor is well suited for small or branch-office Exchange environmentsusing the Dell/EMC CX300 or AX100 storage array.Dell business continuity servicesAfter examining the various types of Dell hardware and supportedsoftware, organizations face the challenge of selecting theappropriate products and integrating them into their Exchangeenvironments for maximum availability and resiliency. Dell businesscontinuity professional services can help perform thesesteps—identifying objectives, suggesting products and technologies,and implementing systems that are designed to meet stipulatedExchange data availability and recovery requirements fororganizations of all sizes.Dell can provide end-to-end business continuity services suchas conducting Exchange migrations, designing and deploying HAand Exchange clusters, and implementing data recovery and storagesystems that use tools such as SAN Copy and SnapView. Dellcan also provide disaster recovery and business continuity planningand services through joint offerings with SunGard AvailabilityServices. In addition, Dell’s partnerships with EMC and Microsoftcan provide administrators with access to underlying technologiesthat enable Exchange environments to benefit from leading-edgefeatures and capabilities without the operational headaches ofmanaging numerous vendors.Strategy for enabling a reliable e-mail environmentOrganizations that have not fully assessed the business continuityrisks to their Exchange environments may be exposed to significantvulnerabilities. Faced with the need to upgrade to ExchangeServer 2003 while meeting stringent compliance regulations, manyadministrators are under increasing internal pressure to developa robust business continuity plan. Creating such a plan meansunderstanding the organization’s tolerance for risk—whether it bedata loss or downtime—and designing the appropriate approachbased on those requirements. The layers of business continuityprotection defined in this article can provide a good starting pointfor creating a business continuity plan.Arun Taneja is the founder, president, and consulting analyst of the TanejaGroup, an analyst and consulting group focused on storage and storagecentricserver technologies.

STORAGE TECHNOLOGYEnhancing Microsoft ExchangeMigrations with VERITAS Enterprise Vault from SymantecAs organizations prepare to replace their legacy e-mail systems with the latest versionsof Microsoft ® Exchange, IT administrators must find a way to migrate these businesscriticalsystems smoothly and efficiently. Most enterprises must address three majorissues during the transition: considerable added infrastructure and resource costs whenlegacy e-mail and Exchange Server 2003 systems must coexist; extended changeovertime, which can affect data availability; and heightened business risks given themission-critical nature of the systems being moved. This article describes how VERITAS ®Enterprise Vault ® software can help organizations overcome such challenges.BY SCOTT ROSENRelated Categories:Data archivingData center technologyE-mail technologyMicrosoft ExchangeStorageStorage softwareVERITASVisit www.dell.com/powersolutionsfor the complete category index.Now that e-mail has become a business-critical applicationfor many enterprises, finding ways to helpreduce the risks associated with e-mail migration is aparamount concern. Administrators must manage severalmajor areas of risk awareness during the transition,including data availability and the potential downtime ofthe core e-mail business system if a failure occurs duringthe changeover from a legacy e-mail system to MicrosoftExchange Server 2003.Many organizations are planning to migrate toExchange Server 2003, which is designed to streamlinemanagement and minimize infrastructure costswhile leveraging the power of the Microsoft platform.But first, enterprises must plan a cost-effective, efficientway to contend with three significant challenges:considerable added infrastructure and resource costswhen legacy e-mail and Exchange Server 2003 systemsmust coexist; extended changeover time, which can affectdata availability; and heightened business risks giventhe mission-critical nature of the systems being moved.VERITAS Enterprise Vault software from Symanteccan help administrators mitigate the risks inherent inan e-mail system migration, whether an organization ismigrating from a legacy e-mail system or upgrading froman older version of Exchange to Exchange Server 2003.Basic guidelines for migratingto Exchange Server 2003A significant proportion of the time, effort, and costsassociated with a migration project can be attributed tothe physical volume of e-mail that must be transitioned.Decreasing the physical volume of data to be migratedcan help minimize overall business risks as well as thecoexistence time when both the old and new e-mail systemsare running together, which can impose a major loadon administrative and support resources.www.dell.com/powersolutions Reprinted from Dell Power Solutions, August 2005.
