3 Caching Sftware Perfrmance: FlashSft 3.8 fr Windws Server Micrsft SQL Server and HammerDB Intrductin The bjective f this paper is t present the perfrmance gains that can be achieved n bare metal and virtualized cmputing envirnments thrugh the use f a hst- based slid- state strage cache enabled by the FlashSft sftware frm SanDisk. Micrsft SQL Server 2014 was installed n a server running Micrsft Windws Server 2012 R2 and perfrmance was measured frm a client cmputer using HammerDB. The database fr the test was cntained n a strage array cmprising SAS- attached hard disk drives (HDDs), which was attached directly t the hst server. 3

The tests were cnducted directly n the bare metal server and virtualized with Hyper- V using a Micrsft SQL Server wrklad measured by the HammerDB benchmark tl. Althugh the tests were cnstructed t be cmparable t the cnditins typically encuntered in real- wrld cmputing and t generate data that reveal representative applicatin perfrmance, the tests can nly be cnsidered a demnstratin f the capability f FlashSft sftware the data shuld nt be interpreted as the perfrmance impact f FlashSft sftware fr all wrklad types and strage envirnments. The actual perfrmance f any caching slutin is highly dependent upn the wrklad and the cmputing envirnment in which it is used. 13

14 Caching Sftware Perfrmance: FlashSft 3.8 fr Windws Server Micrsft SQL Server and HammerDB The applicatin perfrmance test cnducted n the bare metal hst server demnstrates a 4.38 times increase in transactins per secnd as measured by HammerDB. The cache was nly 1/3 the size f the database (wrklad) and was cnfigured in write- back cache mde. The system activity graphs (figures 8 thrugh 12) shw peratin f the cache as it warms up and enhances perfrmance, as shwn by the increased levels and intensity f SQL transactins and disk activity. The file exclusin test highlights peratin f a unique FlashSft feature that allws the administratr t exclude individual files that wuld nt typically benefit frm caching. This frees caching resurces t be applied tward cacheable files such as the database instead f the lg r perating system. Additinally, it eliminates thrashing f the cache that ccurs as the lg is regularly updated with nn- cacheable data intermixed with data f the database. The file exclusin test was cnducted within a virtual machine t allw the lg and perating system VHDx files t be excluded frm cache acceleratin. The parameters f the database and virtual machine strage were adjusted fr this test t perate in the virtual machine. Table 2 illustrates a 2.8 times increase f perfrmance ver baseline when the lg and perating system files are accelerated tgether with the database. Excluding the lg and perating system in rder t accelerate the database nly further dubled the accelerated perfrmance, resulting in nearly 6 times increase in perfrmance cmpared t the baseline.
