SlarWinds Orin Quick Start Guide Chapter 1 Intrductin This chapter intrduces the Orin Failver Engine, prviding an verview f general cncepts related t the prtectin Orin Failver Engine prvides. Orin Failver Engine Prtectin The Orin Failver Engine (Orin Failver Engine) is a Windws-based service specifically designed t prvide high availability prtectin fr SlarWinds Orin installatins withut requiring any specialized hardware. The fllwing sectins describe the varius ways Orin Failver Engine prtects yur SlarWinds Orin installatin: Server Prtectin Applicatin Prtectin Netwrk Prtectin Perfrmance Prtectin Data Prtectin Server Prtectin The Orin Failver Engine prvides cntinuus availability t end users shuld a hardware failure r perating system crash ccur. Additinally, Orin Failver Engine prtects the netwrk identity f the prductin server, ensuring users are prvided with a replica server including server name and IP address shuld the prductin server fail. The Orin Failver Engine sftware is installed n bth a primary server and a secndary server. These names refer t the physical hardware (identity) f the servers. The secndary server has the same name, file and data structure, and netwrk address as the primary server, and runs the same applicatins and services as the primary server. Under nrmal perating cnditins in a nnfailver state the primary server functins as the active server, and the secndary server functins as the passive server. These tw Orin Failver Engine instances regularly send I m alive messages and acknwledgments t ne anther ver a netwrk cnnectin referred t as the SlarWinds Channel t detect interruptins in respnsiveness. If the passive server detects that the mnitring prcess has failed, it initiates a failver. The Orin Failver Engine is symmetrical in almst all respects, and either server primary r secndary can take the active rle, prviding prtected applicatins and services t users. Intrductin 1
A failver is used in mre urgent situatins, such as when the passive server detects that the active server is n lnger respnding. The active server can becme nn-respnsive due t hardware failure, lss f netwrk cnnectivity, r ther cmmunicatin failure. In a failver situatin, the passive server determines that the active server has failed and then immediately assumes the active server rle, as illustrated in the fllwing figure: Applicatin Prtectin The Orin Failver Engine enables yu t maintain yur applicatin envirnment by ensuring that netwrk applicatins and services stay alive. The Orin Failver Engine n the active server uses plug-ins t mnitr the applicatins and services it has been cnfigured t prtect. If a prtected applicatin fails, the Orin Failver Engine first tries t restart the applicatin n the active server (1). If restarting the applicatin fails, then the Orin Failver Engine can initiate a switchver (2) as illustrated in the fllwing figure. A switchver gracefully clses any prtected applicatins running n the active server, and then restarts all f them n the passive server, including the service r applicatin that initially caused the failure, as illustrated in the figure abve. 2 Intrductin
Netwrk Prtectin SlarWinds Orin Quick Start Guide The Orin Failver Engine practively mnitrs the netwrk by plling up t three ndes t ensure that the active server is visible n the netwrk. The Orin Failver Engine plls defined ndes arund the netwrk, including the default gateway, the primary DNS server, and the glbal catalg server, at regular intervals. If all three ndes fail t respnd, fr example, in the case f a netwrk card r a lcal switch failure, the Orin Failver Engine can initiate a switchver, allwing the secndary server t assume a netwrk identity identical t that f the primary server. Perfrmance Prtectin The Orin Failver Engine practively mnitrs system perfrmance attributes t ensure that the system administratr is ntified f prblems and can take preemptive actin t prevent an utage. In additin t mnitring applicatin services, the Orin Failver Engine can mnitr specific applicatin attributes t ensure they remain within nrmal perating ranges. Similar t applicatin mnitring, varius rules can be cnfigured t trigger specific crrective actins when these attributes fall utside f their respective ranges. Data Prtectin The Orin Failver Engine intercepts all data written by users and applicatins, and it maintains a cpy f this data n the passive server that can be used in the event f a failure. The Orin Failver Engine cnfigures itself t prtect files, flders, and even the registry settings n the active server by mirrring these in realtime t the passive server. If a failver ccurs, all files prtected n the failed server are available after the failver, hsted n the secndary server. Orin Failver Engine cntinuusly prvides all five prtectin levels, ensuring all facets f the user envirnment are maintained at all times, and that the principal netwrk cntinues t perate thrugh as many failure scenaris as pssible. Intrductin 3
Cmmunicatins The SlarWinds Channel is a crucial cmpnent f an Orin Failver Engine installatin, and it can be cnfigured in a number f ways, prvided the fllwing cnditins are met: Bth the primary and the secndary servers must have tw r mre netwrk interface cnnectins (NICs). The principal (public) netwrk requires ne NIC. The SlarWinds Channel uses a separate NIC fr the private cnnectin between the prtected servers that is used fr cntrl and data transfer. A secnd pair f NICs can be used t prvide a degree f redundancy fr the SlarWinds Channel. In this cnfiguratin, the SlarWinds Channel has a dual channel if mre than ne dedicated NIC is prvided fr the SlarWinds Channel n each server. T prvide added resilience, the cmmunicatins fr the secnd channel must be cmpletely independent frm the first channel. They must nt share any switches, virtual switches, ruters r the same WAN cnnectin. The IP address a client uses t cnnect t the active server the principal IP address must be cnfigured as a static IP address that is nt DHCP- enabled (Dynamic Hst Cnfiguratin Prtcl). In the figure abve, the IP address is cnfigured as 192.168.1.127. The principal NICs n the passive server are cnfigured t use the same IP address as the active server, but they are prevented frm cmmunicating with the live netwrk thrugh an IP packet filtering system installed with the Orin Failver Engine. This packet filter prevents traffic using the principal address frm being cmmitted t the wire. It als prevents NetBIOS traffic using ther IP addresses n the NIC frm being sent t prevent NetBIOS name reslutin cnflicts. Fllwing restre and after the Orin Failver Engine installatin cmpletes (runtime), NetBIOS is disabled acrss the SlarWinds Channel. This ccurs during installatin t prevent name cnflicts that ccur when bth servers have the same name. 4 Intrductin
SlarWinds Orin Quick Start Guide The NICs n the active and passive servers that supprt cnnectivity acrss the SlarWinds Channel can be standard 100BaseT Ethernet cards prviding a thrughput f 100Mbits per secnd acrss standard Cat-5 cabling, and are cnfigured s their IP addresses are utside the subnet range f the principal netwrk. These addresses are referred t as SlarWinds Channel addresses. Nte: Firewalls prtecting the SlarWinds Channel netwrk cnnectins must be disabled t allw uninterrupted cmmunicatins between the primary and secndary servers. When cnfigured fr a WAN deplyment, the SlarWinds Channel uses static rutes ver switches and ruters t maintain cntinuus cmmunicatins independent frm crprate r public traffic. Only ne server name and netwrk address can be visible n the same netwrk at any ne time. One f these tw servers is live n the principal netwrk and serves the prtected applicatins; this is the active server. The ther server, referred t as the passive server, is hidden frm the principal netwrk, remaining as a ready standby server. Intrductin 5

As a result, ne r mre system restarts may be required. 13. After Plug and Play cmpletes detectin, the setup prcess displays the Finish windw. Actins Required After an Installatin After a successful installatin f the Orin Failver Engine, cmplete the fllwing tasks: 1. Activate the Orin Failver Engine license. 2. Ensure that the Orin Failver Engine is shut dwn. 3. Verify that the date, time, and time zne n the secndary server are identical t the same n the primary server. 4. Start the Orin Failver Engine n the primary server. 5. Start the Orin Failver Engine n the secndary server. 6. Right-click the System Tray icn and select Abut SlarWinds Orin Failver Engine t verify v6.4 (5984) is displayed. Cnfigure actins t take upn failure f a service Orin Failver Engine assigns three sequential tasks t perfrm in the event a mnitred service fails. Task ptins include Recver Service, Applicatin Restart, Lg Warning, Switchver, and any additinal user-defined tasks previusly created. By default, Orin Failver Engine assigns Recver Service t each f the three actins. T cause a switchver in the event f service failure, cnfigure the 3 rd ptin t Switchver.

T cnfigure tasks t perfrm upn service failure: 1. Navigate t Applicatins: Services. 2. Select the intended service. 3. Click Edit and assign a task t each f the three failure ptins, and then click OK. Imprtant: Fr dependent services, failure actins must match the failure actins fr any prtected service n which thse services depend, in bth type and rder. Fr example: Service X is autmatically prtected by Orin Failver Engine Service Y is autmatically prtected by Orin Failver Engine and has a dependency n service X The system administratr sets custm recvery actins fr service X as fllws: First Failure = Recver Service Secnd Failure = Applicatin Restart Third Failure = Switchver In this situatin, the system administratr shuld als set the service recvery actins fr service Y t: First Failure = Recver Service Secnd Failure = Applicatin Restart Third Failure = Switchver Nte that if service X fails, the dependent service Y must als fail. If the service recvery actins fr service Y are different t thse fr service X, they may take precedence, fr example service X requires a switchver but the failure f service Y has already triggered a service restart actin. This advice applies nly t services which are autmatically prtected by Orin Failver Engine and dependent upn ne anther. These dependencies may be examined via the Windws Service Cntrl Manager, under Prperties > Dependencies. Fr services which are shwn in the Prtected services depend n: pane f the Orin Failver Manager Applicatins: Services page, this advice is nt applicable, because: 1. These services d nt depend n prtected services; rather, prtected services are dependent upn them; and 18 SlarWinds Orin Failver Engine Installatin
SlarWinds Orin Quick Start Guide 2. These services are nt directly managed by Failver Engine and therefre have n cnfigurable recvery actins. Nte: If an applicatin with the failure ptin set t Applicatin Restart fails, nly the services that have failed are restarted. Dependent services d nt stp and restart as a result f the failure. When Additinal Pllers (AP)s are nt installed, create an Exclusin Filter t reduce replicatin traffic T prevent needless replicatin f temprary files created when Additinal Pllers are nt used, create an Exclusin Filter. T create the Exclusin Filter: 1. Launch SlarWinds Orin Failver Manger. 2. Navigate t the Data: File Filters pane, and click Add Exclusin Filter t pen the Add Exclusin Filter dialg. 3.

SlarWinds recmmends perfrming a switchver rather than a failver t test the peratin f the passive server. Warning: SlarWinds des nt recmmend attempting t test a failver n a prperly perating server pair using methds such as unplugging a pwer crd. When pwer is lst, any data nt written t the passive server is lst. Failver Simulatin Exercise This exercise demnstrates that the secndary server can functin as the primary server withut the test data being immediately replicated back t the riginal server. During the exercise, yu will stp the primary server frm prviding service and hide it frm the netwrk, then intrduce the secndary server t the netwrk and allw it t prvide service. Nte: Using the System Tray icn, verify that the primary server displays P/A indicating that it is the active server. On the secndary server, repeat the prcess and verify that the secndary server displays S/ indicating that it is passive. Using the SlarWinds Orin Failver Manager, navigate t the Data: Replicatin tab. Verify that bth the File System and the Registry status display as Synchrnized. Ntify any lcal users that the service will be unavailable fr the duratin f the exercise.
