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 excludewekafs
fromupdatedb
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
andenforcing
modes.The targeted
policy is supported.The
mls
policy is not supported yet.
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.
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.

Ethernet configuration
Ethernet speeds: 200 GbE / 100 GbE / 50GbE / 40 GbE / 25 GbE / 10 GbE
NICs bonding: Can bond dual ports on the same NIC (modes 1 or 4)
VLAN: Not supported
Connectivity between servers:
For multiple containers architecture, the default for the Resources Generator is 14000-14100, 14200-14300, and 14400-14500 for the first three containers (these values can be customized).
For single container architecture: Ports 14000-14300.
Mellanox NICs:
One Weka system IP address for management and data plane
Other vendors NICs
Weka system management IP address: One IP per server (configured before Weka installation)

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

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