1. Executive Summary 1.1 Audience This reference architecture dcument is created as part f a Citrix Validated slutin (CVS) and is intended t describe the detailed architecture and cnfiguratin f the cmpnents cntained within. Readers f this dcument shuld be familiar with Citrix XenApp, its related technlgies and the fundatinal cmpnents; Cisc UCS, Cisc Nexus, Nimble Strage and Micrsft Hyper-V Server 2012. 1.2 Purpse The purpse f this dcument is t prvide high-level design infrmatin that describes the architecture fr the Citrix XenApp Hsted Shared Desktp (HSD) Citrix Validated Slutin built n Cisc UCS cmpute, Cisc Nexus switching and Nimble Strage array. 1.3 Reference Architecture In rder t facilitate rapid and successful deplyments f Citrix XenApp Hsted Shared Desktps, Citrix Cnsulting APAC have prcured, built and tested a slutin built n Cisc UCS, Cisc Nexus and Nimble Strage hardware. The Citrix Validated Slutin prvides prescriptive guidance n Citrix, Cisc and Nimble Strage design, cnfiguratin and deplyment settings thereby allwing custmers t quickly deliver Hsted Shared Desktp wrklads using Citrix XenApp. Extensive testing was perfrmed using Lgin VSI t simulate real-wrld wrklads and determine ptimal cnfiguratins fr the integratin f cmpnents that make up the verall slutin. - 5 -
2. Architecture Overview The Citrix Validated Slutin and its cmpnents were built and validated t supprt up t 1,000 individual user sessins running XenApp Hsted Shared Desktps n Windws Server 2008 R2 Remte Desktp Sessin Hsts perating as virtual machine instances n Micrsft Hyper-V Server 2012. This architecture is a single, self-supprting mdular cmpnent identified as a Pd, allwing custmers t cnsistently build and deply scalable envirnments. 2.1 Citrix Virtual Desktp Types Althugh this Citrix Validated Slutin dcument references Citrix XenApp Hsted Shared Desktps it als makes reference t Hsted Virtual Desktps (HVD). Bth types f virtual desktps are discussed belw fr reference. Fr mre infrmatin, refer t Citrix FlexCast delivery methds http://flexcast.citrix.cm/ Hsted Shared Desktp (HSD). A Windws Remte Desktp Sessin Hst using Citrix XenApp t deliver Hsted Shared Desktps in a lcked dwn, streamlined and standardised manner with a cre set f applicatins. Using a published desktp n XenApp, users are presented a desktp interface similar t a Windws 7 lk and feel. Each user runs in a separate sessin n the XenApp server. Hsted Virtual Desktp (HVD) aka Hsted VDI. A Windws 7 desktp instance running as a virtual machine where a single user cnnects t the machine remtely. Cnsider this as 1:1 relatinship f ne user t ne desktp. There are differing types f the hsted virtual desktp mdel (existing, installed, pled, dedicated and streamed). This dcument will primarily discuss the Citrix Validated Slutin fr Hsted Shared Desktps. 2.2 The Pd Cncept The term pd is referenced thrughut this slutin design. In the cntext f this dcument a pd is a knwn entity, an architecture that has been pre-tested and validated. A pd cnsists f the required hardware and sftware cmpnents required t deliver Citrix XenApp capacity fr up t 1,000 Hsted Shared Desktp user sessins. The pd prescribes the physical and lgical cmpnents required t scale ut the number f HSD desktps in increments f 1,000 users r part theref. 2.3 Justificatin and Validatin The cnstruct f this Citrix Validated Slutin is based n many decisins that were made during validatin testing. Testing was carried ut using the Lgin VSI virtual Sessin Indexer (VSI), an industry standard tl fr user / sessin benchmarking. Lgin VSI allws cmparisns f platfrms and technlgies under the same repeatable lad. The Medium VSI wrklad is expected t apprximate the average ffice wrker during nrmal activities and was the wrklad used thrughut testing. - 6 -

Design The Nimble Strage array CS240G-X used within this design prvides a highly available, redundant cntrller slutin within a single 3U enclsure. The Nimble Strage array is a cnverged strage and backup system in ne, which cntains sufficient internal disk capacity prviding the required perfrmance t meet the demands f the slutin. Each cntrller in the Nimble Strage array high availability pair is cnnected with dual data paths t the netwrk, which allws the strage system t perate in the event f cmpnent failure. A single failure f a data path will nt result in a cntrller failver. Frm the hypervisr hst server perspective, a multipath I/O driver will be used t ensure the ptimum path t the strage layer. The Nimble Strage array nly supprts blck based strage using iscsi. This CVS design dcument discusses the use f a Micrsft Windws-based File server fr the purpse f hsting SMB file shares fr data such as user data, user prfiles, ISO and media repsitry and Citrix Prvisining Services vdisk image files.

Pre-defined Applicatin Set Design The HSD XenApp virtual wrklads are deplyed using Citrix Prvisining Services. Citrix Prvisining Services utilises a read nly virtual disk (vdisk) referred t as standard mde (read nly mde used during Prductin mde). This vdisk can als be switched t private mde (writable mde used under Maintenance mde) when updates are required t the base image. Each time updates are applied t this image in Maintenance mde, the image must be generalised t ensure it is ready t be deplyed in its ptimal frm t many target devices. Standard mde images are unique in that they are restred t the riginal state at each rebt, deleting any newly written r mdified data. In this scenari, certain prcesses are n lnger efficient and ptimisatin f this image is required. Optimisatins and cnfiguratins can be applied at several levels: Wrklad Cnfiguratin Glden image. Changes are made directly t the glden image. These changes are cnsidered inapprpriate t be applied using GPOs r are required settings prir t generalising the image.

The final applicatins used and wrklad usage patterns required by the custmer will influence the decisin fr the requirement f a Pagefile. Further custmer validatin will be required. Dependant n the requirement fr a Pagefile and its assciated strage ftprint, the write cache drive may require additinal strage cnsideratins. Further analysis may be required fr custmers with aggressive user lgn time frames t their desktps. In this scenari additinal Web Interface servers may be required and must be added t the NetScaler lad balancing service grup. The Active Directry Frest and dmain will need t be discussed with the Custmer t ensure sufficient capacity exists t supprt any additinal authenticatin requirements the prpsed slutin may impse.
