Prerequisites and compatibility

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

PreviousPay-As-You-Go licenseNextGet support for your WEKA system

Last updated 3 months ago

The versions specified in the prerequisites and compatibility page apply to the latest minor version of the WEKA system. See the relevant release notes in for more details.

CPU

  • Intel SandyBridge+ processors

  • AMD 2nd and 3rd Gen EPYC processors

Ensure the BIOS settings meet the following requirements:

  • AES must be enabled.

  • Secure Boot must be disabled.

Memory

  • Sufficient memory to support the WEKA system needs as described in .

  • More memory support for the OS kernel or any other application.

Operating system

Types

Backends and Clients:

  • RHEL:

    • 7.9, 7.8, 7.7, 7.6, 7.5, 7.4, 7.3, 7.2

    • 8.7, 8.6, 8.5, 8.4, 8.3, 8.2, 8.1, 8.0

  • CentOS:

    • 7.9, 7.8, 7.7, 7.6, 7.5, 7.4, 7.3, 7.2

    • 8.5, 8.4, 8.3, 8.2, 8.1, 8.0

  • Rocky Linux

    • 8.7, 8.6

  • Ubuntu:

    • 18.04.6, 18.04.5, 18.04.4, 18.04.3, 18.04.2, 18.04.1, 18.04.0

    • 20.04.3, 20.04.2, 20.04.1, 20.04.0

  • Amazon Linux: 18.03, 17.09

  • Amazon Linux 2 LTS (formerly Amazon Linux 2 LTS 17.12)

Ensure using an OS with a supported kernel. Do not use an OS with kernel 5.13 for backends in MCB architecture.

Clients only:

  • SuSe:

    • 15 SP2

    • 12 SP5

For kernel 5.13 in clients, do not use applications that use 1GB hugepages.

Configuration

General

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

SELinux

  • SELinux is supported in both permissive and enforcing modes.

    • The targeted policy is supported.

    • The mls policy is not supported yet.

Note: 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).

Kernel

  • 5.3-5.15

  • 4.4.0-1106 to 4.19

  • 3.10

Note: Kernel 5.15 is not supported with Amazon Linux operating systems.

Note: It is advisable to turn off auto kernel updates so it will not get upgraded to an unsupported version.

Weka installation directory

  • Directory: /opt/weka

  • Must be on an SSD or SSD-like performance, for example, M.2.

    • It cannot be shared remotely, NFS mounted, or on a RAM drive.

  • If two boot drives are available, it is recommended to dedicate one for the OS and one for the WEKA /opt/weka directory (there is no need to set software RAID, and some of its implementations are also known to have issues).

  • At least 26 GB is available for the WEKA system installation, with an additional 10 GB for each core used by WEKA.

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

Networking

Note: At least 4k MTU is advised on WEKA cluster servers, NICs, and the switches the servers are connected to.

A WEKA system can be configured without jumbo frames for Ethernet and Infiniband configurations. However, it will provide minimal performance and cannot handle high data loads. Consult with the Customer Success Team before running in this mode.

Jumbo Frames are not required for clients. However, performance might be limited.

Virtual Machines

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

  • 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.

  • 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.

KMS

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

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

Working with this NIC is only supported on RHEL 8.6 and Rocky Linux 8.6. For other operating systems, contact the .

is not yet supported with this NIC.

Weka system data plane IP address: One IP address for each in each server (Weka will apply these IPs during the cluster initialization)

: The maximum number of VFs supported by the device must be bigger than the number of physical cores on the server; you should set the number of VFs to the number of cores you wish to dedicate to Weka; some configurations may be required in the BIOS

Note: If it is necessary to change PKEYs, contact the .

The network is configured as described in .

IOMMU mode for SSD drives is not supported. When IOMMU configuration is required on the Weka cluster servers (e.g., due to specific applications when running the Weka cluster in converged mode), contact the .

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