Ocient System Requirements

in order to run the {{ocienthyperscaledatawarehouse}} , 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 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 ocient hyperscale data warehouse node servers these requirements include the foundation, loader, sql, and metadata node types data (i e non os) drive requirements are listed separately foundation, loader, and sql nodes 137,150,363 false true left false unhandled content type

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

and vdv10152 are known to not work properly with opal enabled upgrade the firmware to a known working version samsung pm9a3 firmware versions gdd5102q and gdd5202q are known to have issues with the vfio pci driver upgrade the firmware to a newer version enterprise nvme drives with similar or better performance characteristics and opal (or better) support can be considered for validation 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 docid\ htxtv efbqavxbystjwef 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 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 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 the minimum recommended link speed is 100gbps 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 enough 100g ports for all foundation nodes on the same backplane for best performance 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 docid\ se gpnu ygkmlyrkj9an 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 docid\ l4to0wifbytuosh5nscob related links ocient software
