Prerequisites and compatibility

This page describes the prerequisites and compatibility for the installation of the WEKA system.

Important: The versions mentioned on the prerequisites and compatibility page are applicable to the WEKA system's latest minor version (4.3.X). For information on new features and supported prerequisites released with each minor version, refer to the relevant release notes available at get.weka.io.

Check the release notes for details about any updates or changes accompanying the latest releases.

In certain instances, WEKA collaborates with Strategic Server Partners to conduct platform qualifications alongside complementary components. Contact your designated WEKA representative with any inquiries.

Kernel

The following kernel versions are supported:

• 6.0 to 6.2

• 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 cgroups V1 (legacy).

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 connecting ports on a single Mellanox NIC 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 enable IOMMU for the server and PCI devices. Manual enablement is not required.

• Mixed networks: This term denotes a configuration in which a WEKA cluster is interfaced with both InfiniBand and Ethernet networks. In the event of dual connections, the system gives precedence to the InfiniBand links for managing WEKA traffic, resorting to the Ethernet links only when complications occur with the InfiniBand network. It’s important to note that in a mixed network cluster, the activation of RDMA (Remote Direct Memory Access) is not possible.

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

HA

See High Availability (HA).

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 TiB.

• 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 and higher)

• Dell EMC ECS (version 3.5 and higher)

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

• HCP for Cloud-Scale V2.x

• IBM Cloud Object Storage System (version 3.14.7 and higher)

• Lenovo MagnaScale (version 3.0 and higher)

• Quantum ActiveScale (version 5.5.1 and higher)

• Red Hat Ceph Storage (version 5.0 and higher)

• Scality Ring (version 7.4.4.8 and higher)

• Scality Artesca (version 1.5.2 and higher)

• SwiftStack (version 6.30 and higher)

Virtual Machines

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

UDP clients

• To avoid irregularities, crashes, and inability to handle application load, make sure there is no CPU starvation to the WEKA process by reserving the CPU in the virtual platform and dedicating a core to the WEKA client.

• The root filesystem must handle a 3K IOPS load by the WEKA client.

DPDK clients

• To avoid irregularities, crashes, and inability to handle application load, make sure there is no CPU starvation to the WEKA process by reserving the CPU in the virtual platform and dedicating a core to the WEKA client.

• The root filesystem must handle a 3K IOPS load by the WEKA client.

• The virtual platform interoperability, such as a hypervisor, NICs, CPUs, and different versions, must support DPDK and virtual network driver.

Special note for a VMware platform

• If using vmxnet3 devices, do not enable the SR-IOV feature (which prevents the vMotion feature). Each frontend process requires a vmxnet3 device and IP, with an additional device and IP per client VM (for the management process).

• Using vmxnet3 is only supported with core dedication.

For additional information and how-to articles, search the WEKA Knowledge Base in the WEKA support portal or contact the Customer Success Team.

KMS

• HashiCorp Vault (version 1.1.5 up to 1.14.x)

• KMIP-compliant KMS (protocol version 1.2 and higher)

  • The KMS must support encryption-as-a-service (KMIP encrypt/decrypt APIs)

  • KMIP certification has been conducted with Equinix SmartKey (powered by Fortanix KMS)
