Networks, Backup & Recovery - Caregroup

Case Backgroud: This case is regarding the interlock outage in CareGroup IT which lasted for about 3 days and how the CareGroup IT was able to resolve this by working in conjunction with cisco Networking team. As the comp whatever did not digit a contingency plan for such an outage, its employees had to switch ski binding to paper establish system, an outdated backup plan knowing for Y2K. John Halamka, CIO of the Caregroup also talks towards the end of the case regarding the lessons erudite from this critical issue which in fact, did not have any adverse effect but rather brought pile CareGroup day-to-day operations.

Case Analysis: Caregroup Network was based on Spanning point Protocol which establishes a single shortest route between the hosts by forcing the redundant paths into a understudy or blocked state. If unity network segment in the STP becomes unreachable, the spanning tree algorithmic program reconfigures the spanning tree topology and reestablishes the link by activating the standby path. IT team started diagnosing this problem by turning sullen network segment /switches to isolate the source of the problem which guide to re-calculating the routes. These calculations were so complex that those switches gave up doing everything else and network collapsed. Switches were turned on so that the network was back up.



Although the network flapped till evening, it did conciliate down in the night due to no activities in the hospitals. The next day, CPU usage started to spike slowing down the network. Caregroup IT team was able to find out the root come of the issue which triggered when a researcher tested an application based on file sharing which copies information across the network which quickly monopolized the entire network slowing down entirely network traffic due to spanning tree protocol laces. Cisco System was called for help which employed CAP (Customer Assurance Program) to take the issue. They did a network audit and pinpointed the problematic spanning tree loop caused by PACS network was...If you want to get a wide essay, order it on our website: Ordercustompaper.com
