Business challenge The hospital's digital construction is a huge and complicated system project. Its overall system is composed of hundreds of business subsystems, and there is frequent data exchange and business linkage between these systems. Brief Introduction The core of this solution is a unified high-performance SAN architecture. Most of the hospital's data is stored in the SAN environment, and different database services and application servers are connected through fiber switches to perform various business processes. To support the increasingly high business continuity requirements of hospitals, we recommend establishing a disaster recovery computer room in a building different from the main center, and using industry-proven technology to implement backup disaster recovery for storage systems. The following is an overview and configuration reference of various parts related to the clinical information system in the construction of the data center (information center). Data Center System Using two 8-way 3.5G processors / 32G memory high-performance minicomputers as the database server host (supporting 16-way processors) TPC-C performance value can reach 500,000 TPMC, the whole machine can be expanded to 1 million TPMC; The host adopts the cluster mode to form a high availability environment (HA); Online storage adopts an open SAN solution (storage area network); The disk array adopts enterprise-level mid-to-high-end fiber arrays with higher performance and 5T storage capacity (supporting storage capacity above 32T); The SAN network uses two 24-port fiber switches (16 ports activated) 4GB bandwidth fiber switches to form the HA mode; Based on the SAN architecture, the backup system recommends the LAN-FREE method to achieve data backup, using special backup software with 4Gb Fibre Channel LTO Ultrium 3, 4 tape library equipment; The application system using WEB mode requires multiple servers to be responsible for running in a balanced mode, and a hardware load balancer with a data throughput greater than 200M needs to be configured. HIS system Background database server and storage system; Use high-performance minicomputer as the host of the database server (support 8 or more processors); and use the partition method to serve various applications; The host adopts the cluster mode to form a high availability environment (HA); HIS online storage uses an open SAN solution (storage area network); The disk array adopts an enterprise-level high-end fiber array with high performance, and establishes independent disk resource space for the HIS system through partitioning; The SAN network uses two 24-port fiber switches (16 ports activated) 4GB bandwidth fiber switches to form the HA mode; The database server host uses dual HBA card redundancy to connect to the SAN switch; The database server uses full redundancy mode (2 network cards) to connect with the core Ethernet switch; The database can choose a relational database as a unified database in the data center, and centrally store various business data. application server Use PC blade server or multiple space-saving rack PC servers as the middle-tier server (supporting 2-way processors) and various single peripheral applications (such as WEB, proxy, intrusion detection, etc.) servers; The number of servers in the middle application layer can be increased according to the scale of the application system and the number of contacts; The middle layer server can realize automatic failover and connection through the application program; The middle-tier server is not connected to the SAN; The middle-tier server can choose whether to connect to the core-layer Ethernet switch in redundant mode.
