4 1 Excutiv Summary Dll and Citrix hav takn a significant stp to liminat th complxity of dsktop virtualization, dvloping a nar turn-ky solution for small and mdium ntrpris customrs who hop to lvrag this complling tchnology. Dsktop virtualization is a provn mthodology for dlivring a rich computing xprinc to nd usrs from cntralizd data cntrs. Ths data cntrs can b on-sit or cloud-basd, in ithr customr-hostd or Dll-managd configurations. In dsktop virtualization th dsktop OS, usr applications, usr prfrncs and usr data ar dcoupld from th clint dvic, giving IT th ability to dlivr dsktops to multipl dvics, improv oprational fficincy and scurity, and ultimatly nhanc nd usr productivity. Dll Dsktop Virtualization Solutions (DDVS) dlivrs ntrpris computing to virtually any nd usr computing dvic, anytim, anywhr whil rducing IT managmnt complxity. DDVS is dsignd to as dsign and implmntation complxitis and addrss ach organization s uniqu businss, usr, and IT rquirmnts. By acclrating adoption of dsktop virtualization organizations can adapt to th dynamics of today s mor mobil and global workforc and tak advantag of th consumrization of IT. Dll Dsktop Virtualization Solutions combin high-prformanc dsktop virtualization softwar with cutting dg Dll hardwar platforms, PC, Thin and Mobil clint dvics, and Dll Srvics to provid scur nd-usr computing, incrasd systms fficincy, and simplifid dploymnt without compromising cntralizd IT control. Citrix VDI-in-a-Box provids a simplifid all-in-on cost ffctiv solution in a convnint applianc that allows smallr companis with limitd budgts and IT staff to lvrag th bnfits of dsktop virtualization. In that way, Dll is truly giving small and mdium businss ownrs th powr to do mor. VDI-in-a-Box intgrats connction brokring, load balancing, dsktop provisioning, high-availability and managmnt functions into a singl packag that runs on standard Dll srvrs with local storag. VDI-in-a-Box also dlivrs anytim anywhr accss with built-in support for Citrix HDX to provid a rich usr xprinc. This rfrnc architctur provids an introduction to th tchnology, faturs and bnfits, targt customr guidanc, gnral sizing guidanc and configuration rcommndations for implmnting a Dll virtual dsktop infrastructur (VDI) solution powrd by Citrix VDI-in-a-Box and Citrix XnSrvr infrastructur. This configuration combins Dll PowrEdg R710 srvrs with VDI-in-a-Box softwar to crat a rsilint VDI solution capabl of providing an nd usr xprinc that is th sam or bttr than a traditional PC dsktop. 1 Dll DVS Simplifid 1010 Rfrnc Architctur

Plas not that th storag rquirmnts includ an 8GB rsrvation for Citrix XnSrvr. This 8GB allocation is split across two 4GB partitions and is usd by th XnSrvr host control domain (dom0). Th following tabl dtails th mthods by which to assum storag capacity: Storag Disk Spac 12 Dll DVS Simplifid 1010 Rfrnc Architctur

This mans th virtual machin is a copy of th goldn imag and in turn, shars virtual disks of th parnt clon (i.., goldn imag). This is why th storag rquird pr VM is only 15% of th goldn imag as opposd to 100%. In ordr to provid linkd clons, VDI-in-a-Box must copy th goldn imags to ach srvr on th grid so that linkd clons can b cratd on ach host srvr. Not that XnSrvr must b configurd to utiliz thin provisioning in ordr to tak advantag of this 85% storag rduction. Othrwis, ach VM would rquir 100% of th disk spac rsrvation usd by th goldn imag. For xampl, if th goldn imag is 30GB and thin provisioning was not configurd on XnSrvr, ach VM would nd at last 30GB of local storag spac Disk Spac Rquirmnts Th VDI-in-a-Box kmgr virtual machin must b installd on ach applianc.

Th nxt important factor whn considring storag capacity is th typ of local storag (.g., SATA or SAS) to utiliz for virtual machins. Th typ of storag must b abl to accommodat th amount of input/output oprations pr scond (i.., IOPS) that originat from th virtual machins. Not that ach virtual machin may b allocatd diffrntly and thrfor must tak into account th usr profil assignd.

It should b notd that total numbr of usrs for ach tst run typically xcds th numbr of dsktops availabl, th rason for this is that th Dll tam found it was ncssary to configur th Login VSI tool to launch mor sssions than wr actually ndd sinc thr is always a prcntag of th usrs that fail to fully connct in vry run, this is somthing that was notd by Login Consultants in thir documntation. VDI UX is basd on th following 9 mtrics: Usr login Application load tim CPU Quu Pag faults Disk IOPS Disk Quu Ntwork latncy Non rsponding applications Incomplt connction Each tim th ConnctorID(CID) in th VDI sssions snds a rport, Stratusphr associats a VDI UX scor to th machin and th usr loggd in at th tim. Th final VDI UX labl (good/fair/poor) associatd with a usr or a machin in a rport is calculatd basd on all th VDI UX ratings obsrvd during that tim priod, not on th individual avrag mtrics obsrvd during that tim priod. This xplains why a singl usr could b labld as fair whil no avrag for th 9 mtrics usd to calculat VDI UX is abov th Good VDI UX profil. This can b th cas whn usag is calculatd ovr short priod of tim and whn obsrvd mtrics ar clos to th thrshold. VDI UX classification for a tim priod is compild basd on th VDI UX ratings rcivd for ach CID (agnt) rport. So a fw paks could mov a usr ovrall rating from good to fair although th avrag valus obsrvd for that sam tim priod ar blow th fair thrshold.
