Nimbl Storag has dvlopd an ntirly nw approach to data storag that convrgs primary and backup storag into on array, dramatically cutting costs and complxity. To bttr undrstand why xisting storag systms cannot solv today's IT problms, it hlps to stp back a fw yars and xamin svral ky storag tchnologis that ar still in us today. NIMBLE STORAGE: EXCHANGE 2010 STORAGE SOLUTION 1

2 Mting th Nds of th Modrn Datacntr Th growth of virtualization and srvr consolidation has compoundd th nd for storag to simultanously dlivr suprior prformanc, incrasd capacity, and simplifid data protction. Traditional storag architcturs ar unabl to comprhnsivly mt ths dmands. Nimbl s patntd Cach Acclratd Squntial Layout (CASL ) is th first storag architctur dsignd from th ground up to samlssly intgrat SSDs with high-capacity disks, dlivring affordabl prformanc, intgratd backup and disastr rcovry, and pain-fr oprations. Prformanc and Capacity Efficincy Nimbl s CASL architctur coalscs random writs into a singl RAID strip, improving writ prformanc by 10x -1x compard to traditional systms. Hot data is srvd from flash which rsponds to workload changs within millisconds instad of hours or days. Nimbl s variabl block-basd comprssion tchnology dlivrs capacity savings of 30%-75% with no impact on systm prformanc. Combind with highly fficint snapshots, thin provisioning, and zrocopy clons, Nimbl offrs th industry s bst primary storag dnsity, all in a 3U form factor. Instant Backups and Rstors Nimbl liminats th constraints of traditional backup solutions. Thousands of snapshots can b stord with minimal spac consumption, liminating backup windows, allowing for mor frqunt rcovry points, and nabling quick and fficint rplication ovr a WAN. Nimbl intgration simplifis application-consistnt backups for Microsoft, Oracl, and VMwar. Backups and rstors can b compltd in sconds, improving application-lvl rcovry point objctivs and rcovry tim objctivs. Strss-Fr Oprations Nimbl arrays ar asy to purchas, st up, and us. A singl SKU includs all hardwar and softwar faturs; thr ar no xtra-cost options. Th arrays ar dsignd to b managd by an IT gnralist. An intuitiv UI simplifis managmnt and liminats configuration and administration complxitis. Built-in application profils and protction tmplats mak it asy to tun storag systms to optimiz prformanc and data protction for individual workloads. It is asy to kp Nimbl arrays up and running. Firmwar upgrads ar compltly non-disruptiv. Built-in ral-tim monitoring and phon-hom support flag problms bfor failurs occur. Rmot support accss nabls quick triag, troublshooting, and rmdiation without th nd for onsit accss. NIMBLE STORAGE: EXCHANGE 2010 STORAGE SOLUTION 2

Th Exchang DAG storag was configurd as follows: 4 Activ Mailbox Srvrs and 4 Passiv Mailbox Srvrs. 2 Nimbl Storag CS460G-X2 Arrays. 20 Activ s, 2,0 mailboxs pr databas. Nimbl Storag arrays us doubl-parity to protct against driv failur. Th Nimbl Storag CASL fil systm uss a block chcksum to nsur data intgrity. 2 copis of ach databas. Th ESRP-Storag program focuss on storag solution tsting to addrss prformanc and rliability issus with storag dsign. Howvr, storag is not th only factor to tak into considration whn dsigning a scal up Exchang solution. Othr factors which affct th srvr scalability ar: srvr procssor utilization, srvr physical and virtual mmory limitations, rsourc rquirmnts for othr applications, dirctory and ntwork srvic latncis, ntwork infrastructur limitations, rplication and rcovry rquirmnts, and clint usag profils. All ths factors ar byond th scop for ESRP- Storag. Thrfor, th numbr of mailboxs hostd pr srvr as part of th tstd configuration may not ncssarily b viabl for som customr dploymnt.

CASL intlligntly dcids which driv sctors to rbuild (for xampl only populatd data blocks ar rbuilt and not mpty driv spac). As a rsult a lightly loadd array can rbuild a whol 1TB driv in about 4 hours, and a 2TB driv in about 7 hours. If th driv is not full th rbuild tim would b proportionally shortr. So a half full driv 2TB driv would only tak 3.5 hours to rbuild on a lightly loadd systm. Whn th storag array is vry busy, rbuild tims can tak longr to rduc prformanc latncy for activ applications. **** Nimbl Storag arrays us ral-tim comprssion algorithms that provid 50% capacity savings ovr raw disk sizs. Thus, usabl capacity is 50% largr than th raw capacity of th storag and rprsnts a mor ralistic xpctation for sizing than raw capacity. NIMBLE STORAGE: EXCHANGE 2010 STORAGE SOLUTION 6

7 Bst Practics Exchang srvr is a disk-intnsiv application. Basd on th tsting run using th ESRP framwork, w would rcommnd th following to improv th storag prformanc. For Exchang 2010 bst practics on storag dsign, plas visit Nimbl Storag provids an auto-tuning storag solution that lvrags flash cach and gratly rducs th amount of ffort to siz and layout Exchang mailstors. Cor Storag 1. This solution architctur was dsignd to show th maximum Exchang prformanc capability of a Nimbl Storag array. Environmnts smallr than 40,0 mailboxs routinly shar Nimbl arrays with othr applications such as SQL Srvr and SharPoint. 2. Sparat Exchang and Log volums sinc thy hav diffrnt prformanc charactristics and will tun diffrntly. Us th Nimbl OS prformanc policis for Exchang and Exchang Logs whn crating th rspctiv volums. 3. Nimbl Storag arrays automatically provision storag from a pool of high-dnsity disks protctd by doubl-parity and ar intlligntly acclratd using NVRAM, DRAM and Flash SSD Cach. Nimbl's CASL Fil Systm lvrags ths storag tchnologis nativly to automatically provid scal-out prformanc dramatically highr than traditional tird storag architcturs. Thrfor, you do not nd to spnd xtnsiv tim provisioning storag such that lgacy storag architcturs rquir, Nimbl dos this for you. 4. Plas consult th "Nimbl Storag Bst Practics Guid for Exchang 2010" for currnt implmntation bst practics. Backup stratgy Nimbl Storag provids th first convrgd storag platform that combins primary storag and backup storag in th sam architctur. Virtually all ntrpris storag systms provid th ability to tak snapshots, or point-in-tim copis of data. Snapshots provid a vry fast and fficint way to rcovr from usr rrors and application crashs. Howvr, ntrpriss ar usually limitd to kping at most a fw days worth of snapshots on disk, bcaus storing multipl snapshots can consum larg amounts of xpnsiv and limitd primary storag capacity. This mandats backing up primary data to a sparat disk-basd backup systm frquntly in ordr to stor days worth of backups. CASL nabls instant, application-consistnt backups on th sam array with vry fficint (up to 20x) backup capacity optimization. It capturs comprssd, incrmntal snapshots of th primary data on low-cost drivs at pr-configurd intrvals. Ths backups ar both xtrmly fast (on th ordr of millisconds) and non-disruptiv, bcaus thy do not impact application or storag prformanc. It thrfor bcoms fasibl for ntrpriss to captur frqunt backups spacd just minuts apart NIMBLE STORAGE: EXCHANGE 2010 STORAGE SOLUTION 7

8 (instad of th typical daily backup), nabling much finr rcovry point objctivs (RPOs) and improving data protction. Th Nimbl approach significantly rducs costs by liminating th nd for a sparat backup tir. It also liminats th complxity and administrativ ovrhad of managing massiv data copis btwn tirs. Finally, it nabls much fastr rstors, with rcovry tim objctivs (RTOs) masurd in sconds instad of hours in th vnt of application corruption or usr rror, furthr improving application availability.

Th first on is to masur th squntial rad rat of th databas fils, and th scond is to masur th rcovry/rplay prformanc (playing transaction logs in to th databas). Rad-only Prformanc Th tst is to masur th maximum rat at which databass could b backd up via VSS. Th following tabl shows th avrag rat for a singl databas fil. Host 1 MB rad/sc pr databas MB rad/sc total pr srvr Host 2 MB rad/sc pr databas MB rad/sc total pr srvr NIMBLE STORAGE: EXCHANGE 2010 STORAGE SOLUTION 10

11 Host 3 MB rad/sc pr databas MB rad/sc total pr srvr Host 4 MB rad/sc pr databas MB rad/sc total pr srvr Transaction Log Rcovry/Rplay Prformanc Th tst is to masur th maximum rat at which th log fils can b playd against th databass. Th following tabl shows th avrag rat for 5 log fils playd in a singl storag group. Each log fil is 1 MB in siz. Host 1 tim to play on Log fil (sc) Host 2 tim to play on Log fil (sc) Host 3 tim to play on Log fil (sc) Host 4 tim to play on Log fil (sc) Conclusion This rport dmonstrats Nimbl Storag's ability to mt th prformanc nds of a 40,0 mailbox Exchang 2010 implmntation at 0.15 IOPS and 1,024 MB pr mailbox. Nimbl's CASL fil systm provids tru fficincy by combining high-dnsity storag with flash SSD to nabl groundbraking prformanc within a small rack form factor. Th Nimbl storag architctur also provids additional spac for highly-fficint rdirct on writ snapshots to provid fast full backups of Exchang using Microsoft VSS and Nimbl Protction Managr. This documnt is dvlopd by Nimbl Storag, and rviwd by Microsoft Exchang Product tam. Th tst rsults/data prsntd in this documnt is basd on th tsts introducd in th ESRP tst framwork.
