2 Service Descriptin Distributed Hsting and Distributed Database Hsting Service Descriptin Distributed Hsting ITS Distributed Hsting prvides dedicated and virtual hsting slutins fr custmer applicatins. Thrugh the use f advanced technlgy, ITS prvides multiple platfrms geared t meet custmer cmputing needs n a 24 x 7 basis. These platfrms prvide custmers with highly available, mnitred, and securely managed hsting slutins. The service design includes multiple redundant high-speed Internet cnnectins, security prtectin, cling/envirnmental system supprt and redundant pwer acrss tw gegraphically-dispersed data centers. Supprted hsting envirnments include: Windws and Linux hsting Virtual hsting services fr Windws and Linux UNIX platfrm (Slaris, AIX) Virtual UNIX hsting supprt (Slaris, AIX) Custmers seeking hsting services are prvided with prvisining/planning supprt, deplyment crdinatin, OS patching and security, and mnitring f all hsted instances. ITS prvides a single pint-f-cntact during planning/deplyment as well as 24x7 peratinal supprt. Distributed Database Hsting (Nt included in the standard service ffering) Distributed Database Hsting prvides the database infrastructure required t supprt business applicatins fr yur rganizatin. In cnjunctin with the Distributed Hsting service, the DB team installs and maintains the database resurce t ensure data integrity and security, as well as apprpriate levels f availability and recverability. Distributed Database Hsting ffers Standard and Extended Level Services. Extended Level Services include all Standard Level Services and are individually selected fr specific needs f the client and their system s requirements. Supprt fr each f the services ffered in this area are quted and charged separately. Additinal details are prvide in the Database Hsting Sectin f the ITS Service Catalg. Strage and Backups ITS ffers a wide variety f strage capabilities t supprt Distributed Hsting, including tape, ptical and disk. These capabilities span the mainframe and the distributed hsting envirnments, including bth dedicated physical and virtual hsting fferings. ITS prvides multiple disk and tape tiers such as high-end disk strage, virtual tape, mid-range disk strage, Netwrk Addressable Page 2

3 Service Cmmitments Strage (NAS) devices, Serial Advanced Technlgy Attachment (SATA) disk systems, Strage Area Netwrk (SAN) attached strage, and cntent addressable strage. All hsting envirnments can be integrated with strage, backup, and archive services. Business cntinuity requirements fr business critical applicatins and disaster recvery capabilities can be achieved via leverage f the gegraphically-dispersed Eastern and Western Data Centers, redundant high-speed netwrking, and enterprise backups and data mirrring acrss strage envirnments. Backup/Data Recvery is available based n requirements. Standard media rtatin and retentin schedule is as fllws: Daily incremental backups retained ff-site fr tw weeks Daily incrementals are nt retained lnger than tw weeks unless requested Backups run Mnday thrugh Saturday Full backups are perfrmed weekly and retained ff-site fr 1 mnth (1 cpy per week) Backups mved ff-site daily Distributed Database Hsting Standard Level Services prvides: Physical DB architectural design Installatin and cnfiguratin f the DB engine Design and implementatin f apprpriate DB archive lgs and backup schedule t prvide fr recvery bjectives Maintenance level and security patches t the DB engine Scheduling services fr recurring user-defined cmmand scripts On-call paging and/r alert f DB resurce availability and disk space Database recvery/restratin Distributed Database Hsting Extended Level Services available: Database replicatin Database clustering Extended Prductin Prblem Respnse up t 24 x 7 Database migratin assistance Service Cmmitments The general areas f supprt (such as Incident and Change Management) applicable t every ITS service, are specified in the ITS Glbal Service Levels dcument. The Distributed Hsting target service availability is 99.99%. Page 3

4 Service Cmmitments Distributed Database Hsting s primary gal is t maintain the integrity and recverability f the custmer s data. ITS is cmmitted t prvide availability f the database service at 99% availability except during agreed upn maintenance windws as negtiated with the custmer. Availability reprting and tracking will be accmplished by the cmpletin f service requests in the Incident Management system indicating actual utage times. Database Hsting will wrk with the vendrs t reslve all prductin database dwn issues with a 24x 7 effrt.
