Should be on an SSD or SSD-like performance, e.g., M.2.
Cannot be shared remotely, NFS mounted or on RAM drive
At least 26 GB available for the WekaIO system installation, with additional 10GB for each core used by Weka
Note: For both Ethernet and Infiniband configurations, the WekaIO system can work with any MTU larger than 1400. For best performance, enable jumbo frames both on the switch and the network ports.

NICs bonding: Not configured
VLAN: Not supported
Connectivity between hosts: Ports 14000-14100
​NetworkManager: Disabled
Mellanox NICs:
One WekaIO system IP address for management and data plane
Other vendors NICs
WekaIO system management IP address: One IP per server (configured prior to weka installation)
WekaIO system data plane IP address: One IP address for each WekaIO core in each server (Weka will apply these IPs during the cluster initialization)
WekaIO system management IP: Ability to communicate with all WekaIO 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 WekaIO system, no other application can create virtual functions (VFs) on that device.
