Define the servers and storage required to use an NS Appliance.
How to Define Servers
Define the servers to be used for NS Appliances.
Determine how many NS Appliances are necessary.
When using the redundancy function of NS Appliances, design the environment with two NS Appliances (one for active and another for stand-by).
Determine how many servers are necessary.
Based on the specifications (CPU and memory size) of the dedicated servers for NS Appliances, determine how many NS Appliances will operate on each server, and then determine how many servers are required to operate the same number of NS Appliance calculated in step 1.
Note the following points:
For details on required specifications for servers that can be used for NS Option, refer to "1.4.2 Specifications Required for Servers Dedicated to NS Appliance".
When using the redundancy function of NS Appliances, it is necessary to configure active NS Appliances and stand-by NS Appliances on separate dedicated servers.
A total of 20 instances of NS Appliance can operate on each dedicated server for NS Appliances.
The required memory size and disk space differ depending on the maximum number of NS Appliances that will be operated.
For details, refer to "1.4.2 Specifications Required for Servers Dedicated to NS Appliance".
Determine the servers to use.
Determine as many servers as the number of the servers for NS Appliances estimated in step 2.
When installing NS Option at the same time as ROR CE
Define the servers and specification of the system to be created using ROR CE, including the servers to be used for NS Option.
When installing NS Option on a system with ROR CE installed
Define the servers to be used for NS Option from among the servers in the system.
If no servers satisfy the requirements, add servers that satisfy the requirements.
How to Define Storage
Define the storage to be used for NS Appliances.
Define the required disk space based on the number of servers estimated in "How to Define Servers".
Define the storage to use.
When installing NS Option at the same time as ROR CE
Define the storage and specifications (FC path connection configuration, etc.) of the system to be created using ROR CE, including the storage to be used for NS Option.
For details on the storage that can be used for NS Option, refer to "1.4 Hardware Environment".
When installing NS Option on a system with ROR CE installed
Define the storage and its connection configuration to be used for NS Option from among the storage in the system that meets the requirements described in "1.4 Hardware Environment".
If no storage satisfies the requirements, add storage that satisfies the requirements.
An example of estimating the number of servers and disk space of the storage is given below:
Example
In this example, two servers are required because the CPU and disk size meet the requirements for servers dedicated to NS Appliances but the memory size is insufficient.
For details on specifications required for servers, refer to "1.4.2 Specifications Required for Servers Dedicated to NS Appliance".
Number of NS Appliances: 6
For use as firewalls: 4 (Required memory size: 8 GB)
For use as integrated network devices: 2 (Required memory size: 8 GB)
Server specifications (Common to all servers)
CPU: Intel(R) Xeon(R) Processor L5609
Memory size: 12 GB
Disk space: 300 GB

This section explains system configuration using NS Appliance with blade servers. "Figure 2.2 Example of Blade Server System Configuration" is an example of a system configuration using SAN storage. For details on the hardware that can be used, refer to "1.4 Hardware Environment".
Figure 2.2 Example of Blade Server System Configuration
Software required for the use of NS Option operating on the admin server. A CE license is required.
Software that monitors the hardware status of servers (PRIMERGY) and sends notification of any errors detected via the network.
Software that provides I/O virtualization technology which changes WWNs retained by server HBAs and MAC addresses retained by NICs.
This software is necessary when using SAN storage.
Software used for management of configurations, relationships, troubles, and performance of storage related resources such as ETERNUS.
This software is necessary when using SAN storage.
The blade server for deploying L-Servers during L-Platform creation.
An ROR CE program that operates on a managed server.
A dedicated server for NS Option, on which a physical L-Server is deployed using a cloning image for NS Option to operate NS Appliance.
Storage used as the disk necessary when deploying a physical L-Server on the blade server (dedicated to NS Option). It is necessary when using SAN storage. It is managed by the admin server.
This section explains system configuration using NS Appliance with rack mount servers. "Figure 2.3 Example of Rack Mount Server System Configuration" is an example of a system configuration using SAN storage. For details on the hardware that can be used, refer to "1.4 Hardware Environment".
