Transcript of 4G IT
Install the user/operations infrastructure
Install the LAN infrastructure:
Install the software and configure the equipment
Interconnect the 5 offices to the dedicated, secure WAN
Develop documentation/policy Due to the requirements of the Healthcare Insurance Portability and Accountability Act (HIPAA), Five Points Medical Centers (FPMC) needs assurance that patient confidentiality is maintained at each office and between the 5 offices. At the same time, this information needs to be readily available to the authorized users. As the layered security technologies needed to maintain the required confidentiality are implemented, the system can slow to a crawl. 4G IT proposes to install an IT infrastructure to the five offices that will compensate for this overhead. In a time frame of less than 3 months, 4G IT will provide FPMC with a secured, high speed Local Area Network (LAN) in each of its five offices. The patient and employee data will be maintained and shared, in and between, the offices by specialized, powerful computers, called servers, that are accessed through the LANs through Category 6A cabling. Cat6A is currently the fastest, widely available copper network data cable, capable of up to 10 billion bits per second (Gbps), connecting FPMC users to the servers and each other, through routers, switches and network interface cards (NICs). We will consolidate 14 separate, physical servers, 53 Windows PC workstations and 2 legacy systems such as the old Novell 4.5 and SCO Unix machines which has no redundancy, into a 10 virtual-host server (v-hosts) system as main and backup, all running a Citrix XenServer v6.0.2, hypervisor OS. The servers have redundant, “hot-swappable” DC power supplies and storage hard drives with the other servers acting as hosting backups and for workload sharing. The virtual servers and virtual workstations or virtual machines, aka VMs, can be transferred to any of the other v-hosts. This allows operations to continue, transferred to another server without interruption while repair or maintenance is performed. This consolidation not only reduces the hardware needs, but also the electrical usage and cooling needs for the offices. The information and resources that servers provide to the users will be held in 5 mass-storage devices called a Storage Attached Network (SAN). Information in the SAN is backed up to redundant SAN devices, locally and throughout the 5-office network with storage management software. This data is also archived to digital audio tapes for major regional disasters and an off-site, online digital storage service for much faster recoveries. The 5 SANs also provide “failover” so that operations can continue if one or both local servers or SAN fails. The 22 hard drives in each SAN will be arrayed together in an 11TB, “stripe of mirrors” (like RAID10). This means that they read data 22x and write data 11x faster than they would as individual disks. The SAN’s “Zettabyte” File System (ZFS) uses checksums and data in mirrors to find and heal data corruption, similar to RAID5 parity information, but without using space in the blocks of data. Unlike some other file systems, ZFS maintains data integrity while the system is running. In case of an office power failure, separate rack-mounted Uninterruptable Power Supplies (UPS) allow the servers time to be properly shut down to maintain data integrity until building power is restored. The UPS also keep the AC power steady during utility line fluctuations and keep systems running for short duration outages and brownouts. If an UPS fails, it returns the connected equipment to regular AC line power. These LANs are inter-connected in the FPMC Wide Area Network (WAN) through a Multi-Protocol Label Switching, Virtual Private Network (MPLS VPN), provided by Megapath Communications. The MPLS VPN will provide a fast and dedicated, secure WAN between the five office LANs. This WAN will reduce the insecure bottleneck of a shared high speed connection to the internet, using bonded T1 Ethernet connections Each T1 provides ~1.5 Megabits per second (Mbps) per T1 cable. T1s can be added to increase the inter-office connection speed. This will allow users at FPMC to connect to the internet and communicate globally and locally from anywhere in the buildings where connections are made available. In a nutshell, 4G IT is offering to provide a very secure data system that has some headroom and is fault-tolerant with high availability components.
