All WEKA servers must be synchronized in date/time (NTP recommended)
SELinux is supported in both permissive
and enforcing
modes.
The targeted
policy is supported.
The mls
policy is not supported yet.
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.
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.

WEKA S3
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.
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.
