The following kernel versions are supported:

• 6.0 to 6.5

• 5.3 to 5.19

• 4.4.0-1106 to 4.19

• 3.10

• Kernels 5.15 and higher are not supported with Amazon Linux operating systems.

• It is recommended to turn off auto kernel updates, so it will not get upgraded to an unsupported version.

• Confirm that both the kernel version and the operating system version are listed as supported, as these are distinct components with their own compatibility considerations.

• For clarity, the range of supported versions is inclusive.

Configuration

General

• All WEKA servers must be synchronized in date/time (NTP recommended)

• A watchdog driver should be installed in /dev/watchdog (hardware watchdog recommended); search the WEKA knowledge base in the WEKA support portal for more information and how-to articles.

• If using mlocate or alike, it's advisable to exclude wekafs from updatedb filesystems lists; search the WEKA knowledge base in the WEKA support portal for more information and how-to articles.

SELinux

• SELinux is supported in both permissive and enforcing modes.

  • The targeted policy is supported.

  • The mls policy is not supported yet.

• To set the SELinux security context for files, use the -o acl in the mount command, and define the wekafs to use extended attributes in the SELinux policy configuration (fs_use_xattr).

• The maximum size for the Extended Attributes (xattr) is limited to 1024. This attribute is crucial in supporting Access Control Lists (ACL) and Alternate Data Streams (ADS) in SMB. Given its finite capacity, exercise caution when using ACLs and ADS on a filesystem using SELinux.

Cgroups

• WEKA backends and clients that serve protocols must be deployed on a supported OS with CgroupsV1.

• CgroupsV2 is supported on backends and clients, but not in deployments with protocol clusters.

As of version 4.3.2, RHEL 7.X and CentOS 7.X are no longer supported due to their end-of-life status. If you need assistance upgrading your operating system, contact the Customer Success Team for guidance.

WEKA installation directory

• WEKA installation directory: /opt/weka

  • /opt/weka must be a direct path. Do not use a symbolic link (symlink).

• Boot drive minimum requirements:

  • Capacity: NVMe SSD with 960 GB capacity

  • Durability: 1 DWPD (Drive Writes Per Day)

  • Write throughput: 1 GB/s

• Boot drive considerations:

  • Do not share the boot drive.

  • Do not mount using NFS.

  • Do not use a RAM drive remotely.

  • If two boot drives are available:

    • It is recommended to dedicate one boot drive for the OS and the other for the /opt/weka directory.

    • Do not use software RAID to have two boot drives.

• Software required space:

  • Ensure that at least 26 GB is available for the WEKA system installation.

  • Allocate an additional 10 GB per core used by WEKA.

• Filesystem requirement:

  • Set a separate filesystem on a separate partition for /opt/weka.

Networking

Adhere to the following considerations when choosing the adapters:

• : LACP is supported when bonding ports from dual-port Mellanox NICs into a single Mellanox device but is not compatible when using Virtual Functions (VFs).

• Intel E810:

  • Only supported on RHEL 8.6 and Rocky Linux 8.6. For other operating systems, consult with the Customer Success Team.

  • The ice Linux Base Driver version 1.9.11 and firmware version 4.0.0 are required.

• It is recommended to set the MTU to at least 4k on the NICs of WEKA cluster servers and the connected switches.

• If any network connection, irrespective of whether it’s InfiniBand or Ethernet, on a given backend possess the capability to transmit frames exceeding 4 KB in size, it is mandatory for all network connections used directly by WEKA on that same backend to have the ability to transmit frames of at least 4 KB.

• support WEKA automatically detects and enables IOMMU for the server and PCI devices. Manual enablement is not required.

• Mixed networks A mixed network configuration refers to a setup where a WEKA cluster connects to both InfiniBand and Ethernet networks. In such configurations, WEKA prioritizes InfiniBand for traffic management, switching to Ethernet only if issues arise with the InfiniBand network.

  RDMA (Remote Direct Memory Access) is not supported in mixed network clusters.

  Supported mixed connectivity MTU settings

  • Ethernet (9000) + InfiniBand (4K)

  Non-supported mixed connectivity MTU settings

  • Ethernet (1500) + InfiniBand (4K)

  • Ethernet (9000) + InfiniBand (2K)

• IP addressing for dataplane NICs Exclusively use static IP addressing. DHCP is not supported for dataplane NICs.

• WEKA peer connectivity requires NAT-free networking

  WEKA requires visibility and connectivity to all peers, without interference from networking technologies like network address translation, or NAT.

HA

See Network High Availability

SSDs

• The SSDs must support PLP (Power Loss Protection).

• WEKA system storage must be dedicated, and partitioning is not supported.

• The supported drive capacity is up to 30 TB.

• IOMMU mode is not supported for SSD drives. If you need to configure IOMMU on WEKA cluster servers, for instance, due to specific applications when running the WEKA cluster in converged mode, contact our Customer Success Team for assistance.

• The ratio between the cluster's smallest and the largest SSD capacity must not exceed 8:1.

To get the best performance, ensure TRIM is supported by the device and enabled in the operating system.

Object store

• API must be S3 compatible:

  • GET

    • Including byte-range support with expected performance gain when fetching partial objects

  • PUT

    • Supports any byte size of up to 65 MiB

  • DELETE

• Data Consistency: Amazon S3 consistency model:

  • GET after a single PUT is strongly consistent

  • Multiple PUTs are eventually consistent

Certified object stores

• Amazon S3

  • S3 Standard

  • S3 Intelligent-Tiering

  • These storage classes are ideal for remote buckets where data is written once and accessed in critical situations, such as during disaster recovery:

    • S3 Standard-IA

    • S3 One Zone-IA

    • S3 Glacier Instant Retrieval

    Remember, retrieval times, minimum storage periods, and potential charges due to object compaction may apply. If unsure, use S3 Intelligent-Tiering.

• Azure Blob Storage

• Google Cloud Storage (GCS)

• Cloudian HyperStore (version 7.3)

• Dell EMC ECS (version 3.5)

• HCP Classic V9.2 and up (with versioned buckets only)

• SwiftStack (version 6.30)

• Dell PowerScale S3 (version 9.8.0.0)

Virtual Machines

This section outlines the use of virtual machines (VMs) with WEKA, covering backends, clients, VMware platforms, and cloud environments. While VMs can be used in certain configurations, there are specific limitations and best practices to follow.

Backends

Virtual machines may be used as backends for internal training purposes only and are not recommended for production environments.

WEKA provides best-effort support for backends deployed on virtual machines, but full support is not guaranteed. Additionally, WEKA does not guarantee support for components or configurations outside of our documented and supported cloud environments, and performance may vary.

Clients

Virtual Machines (VMs) can be used as clients. Ensure the following prerequisites are met for each client type:

• UDP clients:

  • Reserve CPU resources and dedicate a core to the client to prevent CPU starvation of the WEKA process.

  • Ensure the root filesystem supports a 3K IOPS load for the WEKA client.

• DPDK clients:

  • Meet all the requirements for UDP clients.

  • Additionally, verify that the virtual platform (hypervisor, NICs, CPUs, and their respective versions) fully supports DPDK and the required virtual network drivers.

VMware platform (client only)

When using vmxnet3 devices, do not enable the SR-IOV feature, because it disables the vMotion functionality. Each frontend process requires a dedicated vmxnet3 device and IP address, with an additional device and IP for each client VM to support the management process.

Core dedication is required when using vmxnet3 devices.

VMs and instances on cloud environments

Refer to the cloud deployment sections for the most up-to-date list of supported virtual machines and instances in various cloud environments.
