2.3.1 JP1/DH - Server machine
- Organization of this subsection
(1) Preparing dedicated server machine
Your JP1/DH - Server machine must be dedicated to running JP1/DH - Server, and any other system must not reside on this machine together.
JP1/DH - Server features the high-speed file transfer. For functions to perform their best, the system must be able to intensively use resources on the machine, such as CPU, memory, disk I/Os, and bandwidth of the network interface.
(2) Hardware specifications
Information about hardware specifications required for building a JP1/DH - Server machine is as follows.
(a) CPU
CPU performance significantly affects the performance of data transfer and reception. With poor CPU performance, you cannot obtain a satisfactory transfer rate, even with sufficient network bandwidth. The performance of CPUs is affected by some factors, including the clock frequency and number of cores. The CPU requirement for the JP1/DH - Server machine is as follows:
-
Dual core 64-bit processor (2.4 GHz or higher)
(b) Memory
JP1/DH - Server consumes a significant amount of memory when transferring and receiving large files or concurrently accepting multiple connections to the system. If the machine has a smaller amount of memory, you cannot obtain a satisfactory transfer rate when a large file is transferred and received, or when multiple files are transferred concurrently. The memory requirement for the JP1/DH - Server machine is as follows:
-
3 GB or more
(c) Required amount of disk space
You can estimate the required amount of disk space by adding together the following disk space amounts:
-
Disk space for installing the application: Approximately 2,048 MB#
-
Disk space required for the database at run-time: Approximately 32,768 MB#
-
Disk space for storing delivery data
You can estimate this amount based on the average file size of deliveries, the number of deliveries per day, and the storage period of the data by using the calculation formula mentioned below.
Disk space for storing delivery data:
Average file size of deliveries (in MB)
number of deliveries per day
maximum storage period of the data (in days)
#: The amount contains a temporary space consumed by the running database, and the actual usage might be somewhat different.
(d) Network interface
Performance of the network interface significantly affects the performance of data transfer and reception. The network-interface requirement for the JP1/DH - Server machine is as follows:
-
1 Gbps or greater
(3) Cluster operations
For the configuration to operate your JP1/DH - Server in a clustered environment, see C. Configurations for Clustered System Operations.
(4) Storage redundancy
Storage devices of the JP1/DH - Server machine must be redundant to improve their availability. For example, you can set up your system drives or data-storage drives in a RAID configuration.
In this case, make sure that the redundant configuration will not deteriorate disk I/O performance. Poor disk I/O performance prevents JP1/DH - Server from providing a sufficient transfer rate.
