STORAGE TECHNOLOGYwhich can lead to a situation in which migrated data consumesmore physical storage in the target environment than necessary.Enterprise Vault is designed to reduce the physical requirementsfor storing this data through archiving and the re-creation oflost single-instancing. The process can be seamless to end usersbecause their original e-mail messages are replaced with shortcuts.Moreover, because this approach helps keep physical storagerequirements low, it also helps minimize the associated costs ofmanaging migrated content.Minimize the size of Exchange databases after migrationFinally, Enterprise Vault can help organizations that have alreadycompleted their Exchange migration projects and, as a result, havelarger private and public databases than before the migration, alongwith a corresponding increase in backup and recovery times.In this case, the primary concern is to reduce the size of theExchange databases quickly and, if necessary, limit their size tocontrol unnecessary growth. The desired outcome is a definedservice-level agreement for Exchange performance, a predictablebackup and recovery strategy, and a reduction in ongoing storageand storage management costs. Exchange-initiated mailbox quotasmay be used to limit mailbox sizes, but this approach can lead endusers to create .pst files or delete information, which may increasethe risk that important content such as corporate records will belost. By introducing an archiving policy in conjunction with a mailboxquota, administrators can keep Exchange growth under controlin a way that is unobtrusive to end users, preserving long-termaccess to important Exchange content. An example archiving policyusing this model might constrain mailbox sizes by archiving at75 percent of a mailbox quota of 100 MB, thus effectively limitingthe Exchange database to 75 MB multiplied by the number ofmailboxes, with an effective mailbox size governed by the amountof storage allocated to a mailbox archive.Best practices for Enterprise Vault–assistedExchange migrationsDetermining the appropriate method for Enterprise Vault–assistedExchange and legacy e-mail system migration may be governedby factors such as the following:• Degree of data availability and system downtime theorganization finds acceptable for such migration projects• Availability of storage to address migrated e-mail content• Availability of backup technology to address migratede-mail content• Time available to perform the migration process• Status in terms of the migration project (not started, inprogress, or concluded)• Budget available for resources and software tools neededto perform the migrationWhen an organization implements VERITAS Enterprise Vault earlyin the planning stage of a migration project, the benefits of EnterpriseVault help justify the project expense and storage costs because theycan enable a significant reduction in resource and management costsand a general reduction in overall project risk. The later that VERITASEnterprise Vault is used in a migration project, the more its benefitsderive from storage cost-savings—that is, an organization can moveaway from expensive local disks to cost-effective network attachedstorage, storage area networks, or other Dell and Dell/EMC storageoptions. The most common methods for using Enterprise Vault toassist in the Exchange migration process are to avoid moving mailboxcontent and to minimize the mailbox content being moved, asdiscussed in the section “Enterprise Vault migration methods.”Regardless of an organization’s stage in a migration project,one type of mail content can benefit significantly from the use ofEnterprise Vault: Microsoft .pst files. Enterprise Vault provides functionalityto archive .pst content and help eradicate .pst files from theorganization in an end-to-end process. This approach is designed toreduce the cost of the migration process by helping ensure that eachstage is managed and controlled; to automatically determine .pstcontent ownership, which helps minimize the time taken to completethe process and also enables flexible security maintenance;and to allow a choice of server-based pull migration or client-basedpush migration—or a combination of both. Enterprise Vault alsois designed to reduce risk and enable organizations to save timeand money by migrating, repatriating, and consolidating .pst filecontent into an archive that is seamlessly accessible by MicrosoftWindows ® OS users.An effective tool to help organizations move forwardPlanning for a successful and error-free transition to MicrosoftExchange Server 2003 depends on several factors, but the actualmigration process will not be a risk-free operation. Using VERITASEnterprise Vault to assist in the management of Exchange contentcan help minimize infrastructure and resource costs, migrationtime and the migration’s impact on data availability, and the riskof downtime that prevents access to business-critical e-mail systems.Enterprise Vault is designed to be a powerful tool to helporganizations migrate to and take advantage of the next generationof e-mail systems.Scott Rosen manages the Global Dell Relationship and Appliance Systemsfor the VERITAS Enterprise Vault suite, a product from Symantec Corporation.His focus is on building solutions with Dell technology.

STORAGE TECHNOLOGYDeploying theMcDATA 4314 Fibre ChannelSwitch Module for the Dell PowerEdge 1855 Blade ServerBy integrating the McDATA ® 4314 Fibre Channel switch module into the Dell ModularServer Enclosure, data center administrators can create a Fibre Channel storage areanetwork (SAN) for the Dell PowerEdge 1855 blade server or expand their current SAN.Understanding the user-friendly features and monitoring capabilities of the McDATA4314 Fibre Channel switch can help administrators simplify storage management inSAN environments.BY RICHARD GOLASKY AND STEPHANIE HARTLEYRelated Categories:Blade serversDell PowerEdge blade serversFibre Channel switchesFibre ChannelMcDATAStorageStorage architectureVisit www.dell.com/powersolutionsfor the complete category index.The Dell PowerEdge 1855 blade server and the DellModular Server Enclosure offer many features that canbenefit data center administrators. Given the capability tocombine servers, Ethernet switches, systems managementinterfaces, and even a storage area network (SAN) fabricinside a single chassis, administrators no longer need toallocate large amounts of floor space for such data centercomponents. The addition of a blade-sized Fibre ChannelSAN interface—such as the McDATA 4314 Fibre Channelswitch module—to a blade server enclosure enables administratorsto easily integrate this SAN component into FibreChannel infrastructures. Using the integrated McDATA 4314in a Dell Modular Server Enclosure allows organizationsto reduce the per-port cost of Fibre Channel connectivitycompared to external Fibre Channel alternatives.An internal Fibre Channel switch such as the McDATA4314 is typically preferred over a Fibre Channel pass-throughmodule interconnected to an external switch, except whena minimal number of server blades in a chassis are connectingto a SAN or when existing switches have numerousavailable ports without any potential future use. The internalswitch is preferred over the pass-through module primarilybecause, when a pass-through module is used toconnect to an external switch, the number of ports neededon the external switch is dependent on the number ofserver blades installed in the enclosure. When a systemuses the switch module, a maximum of four ports can beused on the interconnected external switch, regardless ofthe number of server blades installed in the chassis.The Dell Modular Server Enclosure supports theMcDATA 4314 Fibre Channel switch module (FCSM). TheMcDATA 4314 is a 14-port switch that installs in modulebay 3 of the enclosure for nonredundant fabrics, or inmodule bays 3 and 4 for redundant fabrics. An importantcost-saving benefit is that the McDATA 4314 doesnot require separate licenses to enable additional Fibrewww.dell.com/powersolutions Reprinted from Dell Power Solutions, August 2005.
