expensive. Generally, IBM and EMC have many outsourced devices, but few HDS devices, which is too expensive. (Ps, some people will say that Dell's storage outsourcing is from EMC to OEMs. Some of IBM's network outsourcing services are the follow-up services of brocade equipment OEMs)As for medical system, what we do most is the small data center in the hospital.

The Oracle installation and configuration process is closely related to the operating system, storage, and network. Especially in Linux and AIX environments, the configuration process is relatively complex. A link error may cause a series of faults in the future.In addition, the steps and methods for executing the same installation project vary greatly with the Oracle version. For example, Data Guard has th
