4 MANAGING A DATACENTER USING MOBILE DEVICES TECHNICAL FIELD [0001] One or more embodments of the present nventon relate to managng a datacenter usng moble devces. BACKGROUND [0002] Modern datacenters can take varous forms. Some datacenters are permanent nstallatons consstng of large?oor plans havng row after row of racks full of blade servers, some of Whch permanent nstallatons are over a football?eld n length. Other datacenters are trackable datacenters that are bult from equpment shpped n contaners. In ether case, a typcal datacenter nvolves thousands of servers. For example, at a densty of up to 128 blade servers per fully loaded rack, an average szed corporate conference room could hold about 3000 servers. [0003] Today, datacenters nclude physcal servers (also referred to heren as hosts) on Whch a multplcty of vrtual machnes (VMs) are run to enable servers to provde desred nformaton technology (IT) functonalty. As s known, n such datacenters, a datacenter management system (DMS) s typcally used to manage an executng envronment n the datacenter so t can provde an approprate level of servce to an enterprse. As s also known, and among other thngs, datacenter management entals movng VMs from one phys cal host to another to balance loads, and to provde functon alty such as (a) fault tolerance such as that provded by VMWare vspheretm 4 Fault Tolerance software dstrbuted by VMWare, Inc. of Palo Alto, Calf.; and (b) dstrbuted resource schedulng such as that provded by VMWare vspheretm 4 Dstrbuted Resource Scheduler (DRS) software dstrbuted by VMWare, Inc. of Palo Alto, Calf. [0004] IT managers face substantal problems n managng datacenters. In partcular, techncans often have a problem n locatng themselves as Well as spec?c hardware n a large datacenter. In addton, because even a smaller datacenter can be densely packed Wth equpment, locatng spec?c hard Ware to perform audts, repars and upgrades s problematc. Unfortunately, problems n locatng spec?c hardware can lead to long delays. These problems may be further exacer bated When managng datacenter functonalty nvolvng datacenters n multple geographc locatons. [0005] Current DMSs provde relatvely low level hard Ware nformaton about the health of hosts n a datacenter nventory. For example, a typcal example of such a DMS shows fan status, motherboard temperature, CMOS battery condton, and varous other useful sensor data. In fact, n some cases such a DMS may provde enough nformaton for a techncan to dentfy a host hardware health ssue. HoW ever, such a DMS typcally makes no mappng avalable between vrtual nventory objects and ther physcal loca tons. As a result, such a DMS does not enable users to navgate and manage actual datacenter nfrastructure n a hands-on fashon. To better understand the problem, assume that a techncan had to?x a malfunctonng fan on a host. The techncan Would?rst need to locate a datacenter nventory manager to obtan the physcal locaton of the host Whose fan s malfunctonng. Then, the techncan Would need to ask a datacenter vrtual nfrastructure (VI) admnstrator to evacu ate all VMs from the host (for example, by movng them to other hosts), and to put the host nto a mantenance mode. Fnally, the techncan Would search about the datacenter to locate the ho st by searchng for the rack, chasss and slot n the chasss at Whch the host s located. Most often, one person alone cannot?x a problem lke ths n an end-to-end fashon today. [0006] Another llustraton of such problems may be seen from the followng scenaro. One common Way to stage an operaton n a datacenter s to have a buld room nearby for assembly, testng, and other preparaton before a server s taken nto the datacenter. When a server malfunctons, a tech ncan locates a replacement server, brngs the replacement server to the buld room, con?gures the replacement server hardware to match the hardware of the malfunctonng server, determnes the verson of vrtualzaton software runnng on the malfunctonng machne, nstalls that verson of vrtual Zaton software on the replacement server, and tests the replacement server for compatblty. When the techncan s ready to swtch out the malfunctonng server, the VI admn strator logs nto the DMS Whch runs, for example, VMWare vspheretm 4 software dstrbuted by VMWare, Inc. and has t: (a) evacuate the VMs from the malfunctonng server, (b) put the malfunctonng server nto mantenance mode, and (c) power t down. The techncan then goes nto the datacenter, swaps the server hardware, powers up the replacement server, Walks back to the buld room, updates an external nventory management system, and?nally alerts the VI admnstrator. The VI admnstrator logs back nto the DMS, Whch, n turn, removes the malfunctonng server from the nventory, adds the replacement server to the nventory, and?nshes con?g urng the replacement server. [0007] Although laptop or desktop computers appear to be a good choce for use n managng datacenter nfrastructure (for example, techncans could carry laptops n the data center), they are cumbersome at best, and requre one to plug n external sensors such as a compass, a Global Postonng System (GPS), a camera, a barcode scanner, and other mod ern sensors. To overcome ths problem, some have tred to use the same software products that are used on a laptop or a desktop computer on a moble devce. HoWever, the form factor of a moble devce lmts ts usefulness snce t s unrealstc to execute all the use cases covered by a desktop clent on a moble devce. SUMMARY [0008] One or more embodments of the present nventon solve one or more of the above-dent?ed problems by pro vdng methods for managng a datacenter usng moble devces. In partcular, one embodment of the present nven ton s a method for managng a datacenter usng a moble devce, Whch method comprses: (a) n response to a user request, the moble devce causng an dent?caton prober to obtan nformaton from one or more of a pluralty of dent?caton provders dsposed at predetermned locatons n the datacenter, and determnng a moble devce locaton n the datacenter therefrom; (b) the moble devce requestng a data center map from a datacenter management system, dsplay ng at least a porton of the map on a moble devce dsplay, and dsplayng the moble devce locaton on the at least a porton of the map; and (c) the moble devce obtanng an equpment locaton of an equpment n the datacenter from the datacenter management system, dsplayng drectons from the moble devce locaton to the equpment locaton,

5 and dsplayng the equpment locaton on the at least a porton of the map f t?ts n the dsplay. BRIEF DESCRIPTION OF THE DRAWINGS [0009] FIG. 1 s a block dagram of apparatus used to man age a datacenter n accordance Wth one or more embod ments of the present nventon, Whch apparatus ncludes a moble devce. [0010] FIG. 2 s a block dagram llustratng a method for managng a datacenter usng a moble devce, Whch method operates n accordance Wth one or more embodments of the present nventon. DETAILED DESCRIPTION [0011] As shown n FIG. 1, n accordance Wth one or more embodments of the present nventon, datacenter manage ment system (DMS) 100 comprses, for example and Wthout lmtaton, datacenter manager server 200 that s located Wthn or Wthout datacenter 300, and data center manage ment software. As further shown n FIG. 1, DMS 100 nteracts Wth moble devce 400, for example and Wthout lmtaton, a personal dgtal assstant ( PDA ) or a smart phone usng, for example and Wthout lmtaton, the moble devce s W-F connecton or 3G connecton. [0012] RFID-Reader-Enabled and/or Barcode-Reader-En abled Moble Devce [0013] In accordance Wth one or more embodments of the present nventon, and as shown n FIG. 1, rado frequency dent?caton (RFID) reader 900 s enabled to transmt nfor maton to and/ or to receve nformaton from moble devce 400. As s Well known, an RFID reader ncludes a transmtter that outputs rado frequency (RF) sgnals through an antenna to create an electromagnetc?eld that enables RFID tags to return an RF sgnal carryng nformaton stored n the tag, Whch RFID tag nformaton s then receved by the reader. Some types of conventonal RFID tags are passve tags,.e., tags Wthout an nternal power source that may be energzed by the RF sgnals output by the RFID reader, and actve tags,.e., tags Wth an nternal power source. In accordance Wth one or more embodments of the present nventon, the RFID tag nformaton may nclude the con?guraton of an tem to Whch t s af?xed, and the con?guraton of the tem may nclude nformaton related to spec?catons of the tem. For example, Wth respect to an tem comprsed of a computer system (for example and Wthout lmtaton, a server), the hardware and software con?guraton of the computer system may be stored n an RFID tag attached to the computer sys tem. Other nformaton may also be stored n the tag, such as a lst of maj or components, suppler nformaton, a spare parts lst, and other nformaton about the tem. The con?guraton and other nformaton for the tem may be stored pror to a?rst tme the tem s delvered to nventory. For example, the manufacturer may store ths nformaton n the RFID tag for the tem. In addton, the RFID tag nformaton may be encrypted/decrypted by an applcaton provdng or utlzng the nformaton, respectvely,.e., Whether n DMS 100 or moble devce 400. The RFID tag may have a Wrte-once memory or may have a re-wrtable memory, such as a?ash memory. Also, the RFID tag may be provded on the nsde of a housng of the tem or on another locaton on the tem that s not readly accessble. [0014] In accordance Wth one or more embodments of the present nventon, RFID reader 900 may transmt nformaton to and/or receve nformaton from moble devce 400 usng, for example and Wthout lmtaton, a Unversal Seral Bus (U SB) connecton or a Bluetooth connecton. In accordance Wth one or more further such embodments of the present nventon, RFID reader 900 may also transmt nformaton to and/or receve nformaton from datacenter manager server 200 by, for example and Wthout lmtaton, a Wreless con necton. In accordance Wth one or more embodments of the present nventon, RFID tag nformaton may be stored by moble devce 400 or DMS 100 (notwthstandng Whether: (a) the RFID tag nformaton Was sent drectly to DMS 100 by the RFID tag or (b) the RFID tag nformaton Was retreved from the RFID tag by RFID reader 900 and transferred to moble devce 400 and then to DMS 100). Also, n accordance Wth one or more further such embodments of the present nven ton, an RFID tag may be ndependently powered from the tem Wth Whch t s assocated, and the RFID tag may trans mt nformaton n response to nput receved from DMS 100, for example and Wthout lmtaton, by transmttng and recevng nformaton and commands over a Bluetooth con necton or a W-F connecton to an assocated applance. In accordance Wth one or more embodments of the present nventon, When moble devce 400 nteracts Wth RFID reader 900 n the manner descrbed above, moble devce 400 Wll be referred to heren as an RFID-Reader-Enabled moble devce. [0015] As s Well known, a moble devce such as a smart phone can scan barcodes (l-dmensonal barcodes or 2-d mensonal barcodes) usng a camera contaned theren. In addton, Wdely avalable software enables the moble devce to read and nterpret the barcodes from camera mages. In accordance Wth one or more embodments of the present nventon, When moble devce 400 s enabled to read and nterpret barcodes, moble devce 400 t Wll be referred to heren as a Barcode-Reader-Enabled moble devce. [0016] As used heren, an RFID tag or a barcode (some tmes referred to as a barcode label) may also be referred to heren as an dent?caton provder. In addton, as used heren an RFID reader or a barcode reader may also be referred to heren as an dent?caton prober. [0017] Equpment Installaton [0018] In accordance Wth one or more embodments of the present nventon, a map, an overall?oor plan, and the loca ton of every rack, chasss, and blade (.e., each trackable tem n datacenter 300) s avalable to DMS 100 usng nventory and mantenance database 700. [0019] In accordance Wth one or more such embodments, the locaton of an tem could be determned: (a) at nstallaton by a datacenter desgner and stored n nventory and mante nance database 700; or (b) after nstallaton by an audt and stored n nventory and mantenance database 700. [0020] In accordance Wth one or more further embod ments of the present nventon, RFID tags are a?xed to each trackable tem, and When a trackable tem s nstalled n datacenter 300, a techncan selects a selectable entry on UI dsplay menu 600 ofui dsplay 500 ofmoble devce 400. In response: (a) RFID-Reader-Enabled moble devce 400 causes RFID reader 900 to scan the RFID tag, (b) moble devce 400 determnes the tem ID from the RFID tag nfor maton, (c) moble devce 400 determnes a locaton of the RFID tag n the manner descrbed below, and (d) moble devce 400 transfers the locaton to DMS 100. In response, DMS 100 updates nventory and mantenance database 700. If the orgnal locaton of the tem has changed from that

6 stored n nventory and mantenance database 700 or f there s no entry n nventory and mantenance database 700, DMS 100 sends a request for moble devce 400 to have RFID reader 900 Wrte the new locaton nformaton nto the RFID tag. [0021] In accordance Wth one or more further embod ments of the present nventon, barcodes are a?xed to each trackable tem, and When a trackable tem s nstalled n the datacenter, a techncan selects a selectable entry on UI ds play menu 600 of UI dsplay 500 of moble devce 400.

[0052] As ndcated n FIG. 2, at step 2030 ofmethod 2000, the techncan retreves nformaton relevant to a replacement for the malfunctonng pece of equpment. In accordance Wth one or more further embodments of the present nven ton, the techncan selects a selectable entry on UI dsplay menu 600 that ndcates a readness to replace the malfunc tonng server. In response, moble devce 400 sends the nd caton of readness to DMS 100, and DMS 100, n turn, accesses nventory and mantenance database 700 to obtan a lst of potental replacement equpment that s sutable to replace the malfunctonng server and Whch s accessble to the techncan by, for example and Wthout lmtaton, beng located n a storeroom n datacenter 300. DMS 100 transmts the lst to moble devce 400 for presentaton to the techncan on UI dsplay 500. Alternatvely, DMS 100 sends a request to a storage depot to have approprate replacement equpment transferred to datacenter 300. In such a case, the techncan may obtan a sutable replacement for the malfunctonng server before venturng nto the datacenter.

10 [0053] As ndcated n FIG. 2, at step 2040 ofmethod 2000, the techncan uses moble devce 400 to obtan nformaton from a tag a?xed to the replacement equpment. When the techncan obtans a potental replacement equpment, the techncan selects a selectable entry on UI dsplay menu 600 that causes moble devce 400 to obtan nformaton concem ng the potental replacement equpment. In partcular, moble devce 400 sends a sgnal to RFID reader 900 or the barcode reader (.e., a camera assocated Wth moble devce 400), respectvely, of RFID-Reader-Enabled and/ or Barcode Reader-Enabled moble devce 400, respectvely, to scan an RFID tag or read a barcode, respectvely, that s a?xed to the potental replacement server to obtan ts unque seral num ber and hardware detals. [0054] As ndcated n FIG. 2, at step 2050 ofmethod 2000, the techncan uses moble devce 400 to determne the tech ncan s locaton n datacenter 300. In accordance Wth one or more embodments of the present nventon, When the tech ncan s ready to?nd the malfunctonng equpment, the techncan selects a selectable entry on UI dsplay menu 600 enttled, for example and Wthout lmtaton, Fnd My Phys cal Locaton. In response, UI dsplay 500 presents a map of datacenter 300 on UI dsplay 500 that shows: (a) the techn can s locaton (n the manner descrbed above); (b) an nd caton of the locaton of a rack that contans the malfuncton ng server f the techncan s locaton and the equpment s locaton can?t on the map at the magn?caton desred by the techncan, Whch equpment s locaton s stored n nventory and mantenance database 700; and (c) optonally, drectons for travellng from the techncan s locaton to the locaton of the rack (n the manner descrbed above). [0055] As ndcated n FIG. 2, at step 2060 ofmethod 2000, the techncan uses moble devce 400 to update drectons to the malfunctonng equpment as the techncan moves n datacenter In accordance Wth one or more embodments of the present nventon, as the techncan moves through datacenter 300, the map presented on UI dsplay 500 of moble devce 400 contnues to update the techncan s loca ton (n the manner descrbed above), and UI dsplay 500 contnues to update the drectons to the malfunctonng server (n the manner descrbed above). [0056] As ndcated n FIG. 2, at step 2070 ofmethod 2000, the techncan uses moble devce 400 to obtan locaton spec?c and equpment spec?c nformaton. When the tech ncan gets to the desgnated rack, the techncan selects a selectable entry on UI dsplay 600 that retreves rack data, optonally retreves a photographc mage of the rack, and optonally causes the malfunctonng equpment to provde some physcal manfestaton that ndcates ts dentty (n the manner descrbed above). In response, moble devce 400 request data from DMS 100, and optonally requests DMS 100 to cause the physcal manfestatons to occur. DMS 100, n turn, obtans the data and photograph from nventory and mantenance database 700, and transmts t to moble devce 400 for presentaton to the techncan on UI dsplay 500. In addton, f requested, DMS 100 sends a command to the server to cause t to provde the physcal manfestatons. [0057] As ndcated n FIG. 2, at step 2080 ofmethod 2000, the techncan uses moble devce 400 to obtan nformaton from a tag a?xed to the malfunctonng equpment. In accor dance Wth one or more embodments, When the techncan beleves s/he s at the correct rack, the techncan selects a selectable entry on UI dsplay 600 that causes moble devce 400 to obtan nformaton concernng the malfunctonng server. In partcular, moble devce 400 sends a sgnal to RFID reader 900 or the barcode reader (.e., a camera assocated Wth moble devce 400), respectvely, of RFID-Reader-En abled and/or Barcode-Reader-Enabled moble devce 400, respectvely, to scan an RFID tag or read a barcode, respec tvely, that s a?xed to the malfunctonng server to obtan ts unque seral number and hardware detals. In accordance Wth one or more such embodments, ths nformaton enables DMS 100 to con?rm that the techncan s at the correct locaton and accessng the correct pece of equpment. [0058] As ndcated n FIG. 2, at step 2090 ofmethod 2000, the techncan uses moble devce 400 to put the malfuncton ng equpment n a mantenance mode. In accordance Wth one or more embodments of the present nventon, the tech ncan selects a selectable entry on UI dsplay 600 enttled, for example and Wthout lmtaton, Enter Mantenance Mode. Moble devce 400 forwards the request to DMS 100, and, n response, DMS 100 evacuates all vrtual machnes (VMs) runnng on the server to another server n accordance Wth any one of a number of methods that are Well known to those of ordnary skll n the art, and places the malfunctonng server n mantenance mode. [0059] As ndcated n FIG. 2, at step 2100, the techncan uses moble devce 400 to con?rm compatblty of the replacement and malfunctonng equpment. Next, n accor dance Wth one or more embodments of the present nven ton, DMS 100 creates a pro?le of the malfunctonng server s con?guraton (the pro?le ncludes, for example and Wthout lmtaton, the number and type of CPUs, all network and storage con?guratons, and the verson of vrtualzaton soft Ware runnng on the malfunctonng server), and transmts the pro?le nformaton to moble devce 400 for presentaton to the techncan on UI dsplay 500. In accordance Wth one or more embodments of the nventon, the techncan uses the pro?le to obtan a replacement server or, optonally, the mal functonng server s pro?le Was obtaned pror to the techn can s enterng datacenter 300 (as Was descrbed above), and the malfunctonng server s pro?le Was used to obtan the replacement server at that tme. In accordance Wth one or more embodments of the present nventon, f ths has not been done prevously, the techncan selects a selectable entry on UI dsplay 600 that causes moble devce 400 to obtan a pro?le of the potental replacement server. In partcular, moble devce 400 sends a sgnal to RFID reader 900 or the barcode reader (.e., a camera assocated Wth moble devce 400), respectvely, of RFID-Reader-Enabled and/or Barcode Reader-Enabled moble devce 400, respectvely, to scan an RFID tag or read a barcode, respectvely, that s a?xed to the potental replacement server to obtan ts unque seral num ber and hardware detals. Moble devce 400 transmts the nformaton to DMS 100, and n response, DMS 100 deter mnes Whether the potental replacement server s compatble Wth the malfunctonng server (for example and Wthout lmtaton, DMS 100 determnes Whether the CPU, network and storage con?guratons are sutable so that the replace ment server can perform the tasks prevously performed by the malfunctonng server). Alternatvely, moble devce 400 carres out the compatblty determnaton. If the replace ment server s compatble Wth the malfunctonng server, UI dsplay 500 ndcates that the replacement can be made. In response, the techncan places the replacement server n a rack poston desgnated therefor by DMS 100. [0060] As ndcated n FIG. 2, at step 2110 ofmethod 2000, the techncan uses moble devce 400 to con?rm nstallaton
