# Ocient System Requirements

export const Ubuntu = "Ubuntu®";

export const Supermicro = "Supermicro®";

export const Solidigm = "Solidigm™";

export const Samsung = "Samsung®";

export const RHEL = "Red Hat® Enterprise Linux® (RHEL®)";

export const OcientDataIntelligencePlatform = "OcientAIQ™ Unified Data Platform";

export const Ocient = "Ocient®";

export const NVIDIA = "NVIDIA®";

export const Mellanox = "Mellanox®";

export const Java = "Java®";

export const Intel = "Intel®";

export const Debian = "Debian®";

export const AMD = "AMD®";

In order to run the {OcientDataIntelligencePlatform}, you must meet several requirements for your system hardware, OS, and software. The requirements ensure that your system can run an optimized and fully functional {Ocient} installation.

These requirements apply to the Foundation, Loader, and SQL Nodes.

<Info>
  Consult with Ocient or the System Administrator installing Ocient to determine the optimal configuration for your Ocient deployment.

## Server Hardware Requirements

These are the hardware requirements for the OcientAIQ Unified Data Platform node servers. These requirements include the Foundation, Loader, SQL, and Metadata Node types. Data (i.e., non-OS) drive requirements are listed separately.

## Data Drive Requirements

Ocient strictly requires high-performance enterprise or data center NVMe SSD drives for long-term and short-term data storage. The drives listed here have been validated for functionality and performance. They also support drive self-encryption using the OPAL standard. All data stored is encrypted at rest. Power loss protection (PLP), standard on enterprise and datacenter drives, is also required. An endurance of 0.5 drive writes per day (DWPD) or higher is recommended for Foundation and SQL Nodes, endurance of 1.0 DWPD is recommended for Loader Nodes.

* {Solidigm} D5-P5430 OPAL U.2 3.84TB-15.36TB
* Solidigm D7-P5520 OPAL U.2 1.92 TB-15.36TB
* Solidigm D7-P5510 OPAL U.2 3.84TB, 7.68TB
* {Samsung} PM9A3 U.2 960GB-15.36TB
*

<Warning>
  Solidigm P5510 firmware versions VDV10151 and VDV10152 are known not to work properly with OPAL enabled. Upgrade the firmware to a known working version.
</Warning>

<Warning>
  Samsung PM9A3 firmware versions GDD5102Q and GDD5202Q are known to have issues with the `vfio-pci` driver. Upgrade the firmware to a newer version.
</Warning>

Enterprise NVMe drives with similar or better performance characteristics and OPAL (or better) support can be considered for validation.

<Info>
  If the Ocient System detects hardware support for the OPAL standard, then nodes enable full disk encryption on data drives by default. Ocient stores the encryption keys on the operating system drive. For the complete list of directories to back up, see [Backup and Restore](/backup-and-restore).
</Info>

### Compatible Operating System Versions

These operation systems and versions are fully supported by Ocient:

* {RHEL} version 8\* and version 9
* {Ubuntu} 20.04, 22.04, 24.04
* {Debian} 11, 12

<Info>
  RHEL versions 8.3 and prior require a kernel upgrade for compatibility. There is a bug in the `uio_pci_generic` driver in the kernel provided with those versions that prevents Ocient from communicating with the NVMe drives.
</Info>

## Network Requirements

Ocient requires high-bandwidth connections between its database nodes to achieve high performance. It is critical for performance that the Foundation and SQL Nodes can simultaneously utilize high-bandwidth links without bottlenecks. Generally, this means that those nodes share the same switch backplane for best performance.

<Info>
  The minimum recommended link speed is 100Gbps.
</Info>

### Redundancy

Redundant networking is recommended for production use cases. On the server side, dual port NICs are required to support redundancy. Multi-chassis link aggregation (MLAG/CLAG/MCLAG) using redundant switches is the recommended form of redundancy.

### Network Switch

These are the requirements for the network switches to support Ocient. No other advanced L2 or L3 features are required.

1. Enough 100G ports for all Foundation Nodes on the same backplane for best performance.

2. Multi-chassis link aggregation for redundancy (MLAG/CLAG/MCLAG depending on vendor terminology).

## Security Requirements

To secure data stored on disk, Ocient supports and recommends SEDs (Self-Encrypting Drives) that meet the OPAL (or better) standard. Using drives that support this standard, Ocient software enables encryption of data at rest on the drives. This encryption prevents unwanted data leaks, as any time a disk is removed from the system, it becomes locked, and the data can only be recovered with a key-encrypting-key that is stored off-drive.

To secure network communications, see the [Ocient Security Guide](/ocient-security-guide).

## Additional Software Requirements

Ocient depends directly on these software packages:

* `python3`
* `sudo`
* `lz4`
* `cronie`
* `logrotate`
* `gzip`
* `pciutils`
* `ca-certificates`
* `libquadmath` (RHEL), `libquadmath0` (Ubuntu/Debian)

For database nodes, these packages are installed automatically as part of the package dependencies.

Ocient also depends on a separate installation of {Java} 21, where the `openjdk-21-jre-headless` package is recommended.

## Next Step

If your system meets these requirements, proceed to [Ocient Application Installation](/ocient-application-installation).
