DPOD's web user interface requires the following for administration and end users:
DPOD can be installed on either a Virtualized Environment (Hypervisors) or Physical server (Intel(C) based CPUs and supporting CentOS 7.x OS). Consult the table below for information to support this decision.
For a production environment suitable for hypervisor (virtual environment), the virtual appliance is supported on the following VMware hypervisors:
DPOD offers 6 basic load configuration setups.
Five load configuration architecture setups that exist for the Standard Edition are available in:
Non-Appliance Mode (Compressed Executable file) - DPOD_RedHat_<version>.cef (Can be download from PPA) - for example: DPOD_CentOS_1.0.8.5.cef
The following table lists the typical usage characteristics for each setup edition, and the physical or virtual resources it requires.
Availability in Edition | Load Configuration Architecture Setup | Goal | TPS Limits recommended(4) | Supports Virtual Env | Cores (1) | Memory (3) | Storage (GB) |
---|---|---|---|---|---|---|---|
Developer | Development | Developers only. In rare cases can be used for functional POCs. restricted license | 2-3 | Yes | 2 | 3 GB | All: 20GB |
Standard | Minimal | POCs and Evaluation. Limited history period to reduce memory requirements | 5 | Yes | 4 | 18 GB | OS: 40 |
Standard | Low | Environment with low load levels | 40 | Yes | 6 | 32 GB | OS: 40 |
Standard | Medium | Environment with Moderate load | 80 | Yes | 8 | 64GB | OS: 40 |
Standard | High | Environment with High load | 120 | Yes, but not recommended | 12 | 128GB | OS: 40 |
Standard | High_20dv | Environment with Medium load | 200 Can be increased to 1500 TPS(5) | No. Must be installed on a physical server | 16 (Physical) | 200GB | OS: 40 |
Standard | High_20dv | Environment with High load | 1500 TPS(5) | No. Must be installed on a physical server | 24 (Physical)(5) | 256GB | OS: 40 |
Customers who need to handle more than 1500 TPS will be required to install sepereated multiple nodes.
A customer wants to attach a pool of appliances to DPOD. This pool generates a peak of circa 10,000 TPS ( in average about 35 Syslog records per transaction).
This customer will need to have 7 servers with 2 sockets and 2 Intel based CPUs - each with 12 physical cores of 2.6 Ghz (non turbo) and with hyper-threaded Support . Each server requires 256GB of memory, and storage specification as described below(5).
1 Node = 1500 TPS
7 Nodes = 10,500 TPS.
Each DPOD environment (up to 7 nodes) will support no more than 10,000 TPS.
Customers with the higher load still are expected to create separate environments, each can handle up to 10,000 TPS.
Customers who plan to use more than one node or above 1,000 TPS are expected to submit a sizing questionnaire available to IBM technical sales teams.
Please read more about setup a DPOD Federated Environment
(1) These could be cores on an 80% utilized ESXi
(2) Local SSD preferred - should be located on a data store separated from the other disks
(3) Best query performance is achieved by using reserved memory configuration
(4) The TPS is the total transaction load across all devices/domains connected to DPOD
IBM DataPower Operations Dashboard may also be installed as a custom distributed edition (not All-in-One) that allows installation on several servers located across separate geographical locations.
This normally requires creating a custom architecture based on a sizing process.
(5) To cater for 1500 TPS, customers are required to have 256GB memory, 24 Physical cores (each is HyperThreaded thus equivalent to a total of 48), Local storage with RAID0 across 4-8 SSD Disks (SAS 6GBs) - each supporting at least 80K Random Write IOPS 4KiB and write avg latency of less than 35 uSec. Two controllers will be required to be attached to each CPU. Please keep the ratio between RAM and Data storage size to be 1GB RAM : 16GB Data Disk (recommended) and no more than 1 GB RAM :32GB DISK (minimal).
DPOD does not support the CentOS built-in RAID (Software Raid). The only supported RAID is the one handled by a controller |
An SSH client to connect to the DPOD appliance once installed.
An FTP Client software to upload/edit files in the appliance when required .
