- Before installing a cell environment, make sure to complete the sizing process with IBM Support Team to get recommendations for the hardware and architecture suitable for your requirements.
- DPOD cell manager and federated cell members must be of the same version (minimum version is 1.0.8.6).
- DPOD cell manager is usually virtual and can be installed in both Appliance Mode or Non-Appliance Mode with Medium Load architecture type, as detailed in the Hardware and Software Requirements.
- DPOD federated cell members (FCMs) can be one of the following:
- Physical servers installed in Non-appliance Mode (based on RHEL) with High_20dv architecture type, as detailed in the Hardware and Software Requirements.
Physical servers are used when the cell is required to process high transactions per second (TPS) load. - Virtual servers installed in Non-appliance Mode with Medium architecture type or higher, as detailed in the Hardware and Software Requirements.
Virtual servers are used when the cell is required to process moderate transactions per second (TPS) load, or when the cell is part of a non-production environment where the production cell uses physical servers (to keep environments architecture similar).
- Physical servers installed in Non-appliance Mode (based on RHEL) with High_20dv architecture type, as detailed in the Hardware and Software Requirements.
- A All DPOD cell environment members must have be identical - only physical or only virtual cell members (cannot mix physical and virtual cell members in the same cell).All DPOD federated cell members must have , and with the same resources , such as (CPUs, RAM, disk type and storage capacity).
- Physical federated cell members with 4 CPU sockets and NVMe disks require special disks and mount points configuration to ensure performance. See Configuring Cell Members with 4 CPU Sockets and NVMe Disks.
- Each cell component (manager / FCM) should have two network interfaces:
- External interface - for DPOD users to access the Web Console (on the cell manager) and for communication between DPOD and Monitored Gateways (on both the cell manager and the members).
- Internal interface - for internal DPOD components inter-communication (should be a 10Gb Ethernet interface).
- Network ports should be opened in the network firewall as detailed below:
...
- Make sure to meet the prerequisites listed at the top of this page .Install the following software package (RPM) on the cell member: bc, numactl, and the prerequisites listed at Non-Appliance Installation.
- The cell member server should contain disks according to the recommendations made in the sizing process with IBM Support Team, which includes disks for OS, install, and data (one for /data and 6 to 9 additional disks for /data2/3/4...).
- Install the following software package (RPM) on the cell member: bc, numactl, pciutils, nvme-cli
- Physical federated cell members with 4 CPU sockets and NVMe disks require special disks and mount points configuration to ensure performance. See Configuring Cell Members with 4 CPU Sockets and NVMe Disks.
Most Linux-based OS use a local firewall service (e.g.: iptables / firewalld). Since the OS of the Non-Appliance Mode DPOD installation is provided by the user, it is under the user's responsibility to allow needed connectivity to and from the server.
Configure the local firewall service to allow connectivity as described in the prerequisites section at the top of this page.The following software packages (RPMs) are recommended for system maintenance and troubleshooting, but are not required: telnet client, net-tools, iftop, tcpdump
...
- Use Non-appliance Mode and follow the procedure: Non-Appliance Installation
- Physical servers should use RHEL as the operating system.This installation (before the federation process is executed later) is similar to a standard All-In-One standalone DPOD installation.
In order for this installation to complete successfully, all prerequisites for DPOD installation should be met as described in the installation procedure, including the 3 disk drives requirement (data disk of 100GB only is required)RHEL as the operating system. - The four-letter Installation Environment Name should be identical to the one that was chosen during the Cell Manager installation.
- During installation, when prompted to choose the IP address for the Web Console, choose the IP address of the external network interface.
