Storage Requirements
- DPOD serves as a database and should, therefore, be configured to use very fast disks. For this reason, DPOD installation requires 3 separate DISKS for OS, Installation, and DataDPOD is I/O intensive, as it needs to persist all logs and information at very high rates. Therefore, it needs to be configured with very fast disks, and with at least 3 separate disks (OS, app/logs, data).
- Some configurations, such as the Cell environment, require additional data disks.
- Usage of slow disks is not recommended. It will impact the maximum TPS that DPOD can process, the performance of queries and the amount of time between the creation of transaction logs and the availability of the data on DPOD's dashboards.For Physical hardware installations that can utilize HW RAID services the following setup is recommended:
- RAID5 - 40GB - for OS disk
- RAID5 - 40GB - for App disk RAID0 - Depends on volume - for Data disk
- For each 1 TB of data 64 GB of RAM is recommended for responsive queries (dashboards and filters). Please keep the ratio between RAM and Data storage size to be 1GB RAM: 16GB Data Disk (recommended) and no more than 1GB RAM : 32GB Disk (minimal).
- NFS is not supported for the data disk, as the Store relies on file system behavior that NFS does not supply. Data corruption and other problems can occur.
- Software RAID (such as CentOS built-in RAID) is not supported.
- The data disk retention is automatically managed by DPOD. For each type of data (transactional, resources, payload, etc.), once its quota is full, old data will be discarded to make room for new data of the same type. A bigger disk size will hold a longer history.
Network Requirements
DPOD requires at least one network interface for accessing DPOD's User Interface and communications with Gateway's Management Interface.
