3.10
4.4.0-1106 to 4.19
5.3-5.4
Note: It is advisable to turn off auto kernel updates so it will not get upgraded to a yet unsupported version.
Directory: /opt/weka
Should be on an SSD or SSD-like performance, e.g., M.2.
Cannot be shared remotely, NFS mounted or on RAM drive
If there are two boot drives available, it is recommended to dedicate one for the OS and one for the Weka /opt/weka
directory (there is not need to set software RAID, and some of its implementations are also known to have issues)
At least 26 GB available for the Weka system installation, with an additional 10GB for each core used by Weka
Note: At least 4k MTU is advised on Weka cluster hosts NIC's, and the switches the hosts are connected to.
For both Ethernet and Infiniband configurations, a Weka system can be configured without jumbo frames. However, it will provide very limited performance and will not be able to handle high loads of data; please consult the Weka Sales or Support teams before running in this mode.
Jumbo Frames are not required for clients. However, performance might be limited.

NICs bonding: Not configured
VLAN: Not supported
Connectivity between hosts: Ports 14000-14100
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 prior to Weka installation)
Weka system data plane IP address: One IP address for each Weka core in each server (Weka will apply these IPs during the cluster initialization)
Weka system management IP: Ability to communicate with all Weka system data plane IPs
​Virtual Functions (VFs): The maximum number of virtual functions supported by the device must be bigger than the number of physical cores on the host; you should set the number of VFs to the number of cores you wish to dedicate to Weka; some configuration may be required in the BIOS
SR-IOV: Enabled in BIOS
Note: When assigning a network device to the Weka system, no other application can create virtual functions (VFs) on that device.

VMs can be used as clients only, assuming they meet the following prerequisite:
To avoid irregularities, crashes, and inability to handle application load, make sure there is no CPU starvation to the Weka process by both reserving the CPU in the virtual platform and dedicate a core to the Weka client.
The root filesystem should handle a 3K IOPS load by the Weka client.
The virtual platform interoperability (hypervisor, NICs, CPUs, different versions, etc.) should support DPDK and SR-IOV VFs passthrough to the VM.
The hypervisor hosts and the client VMs should run the same OFED version.
