Introduction
...
The quick start requires a minimum of 2 servers each 1 server with PMEM and SSDs connected via infiniband storage network and 2 client nodes 1 client node and 1 admin node without pmem/ssd but on the infiniband storage network.
All nodes have a base openSUSE or SLES 15.2 installed.
- sudo access configured
- password-less ssh configured
- pdsh installed (or some other means of running multiple remote commands in parallel)
In addition the server nodes should also have:
- an InfiniBand network adapter configured
- one or more NVMe devices
- IOMMU is enabled https://daos-stack.github.io/admin/predeployment_check/#enable-iommu-optional
For the use of the commands outlined on this page the following shell variables will need to be defined:
- ADMIN_NODE
- CLIENT_NODES
- SERVER_NODES
- ALL_NODES
For Install pdsh
| Code Block |
|---|
sudo zypper install pdsh |
For example, if one wanted to use node-1 as their admin node, node-2 and node-3 as client nodes, and node-[4 and node-6] 5 as their server nodes then these variables would be defined as:
| Code Block |
|---|
ADMIN_NODE=node-1 CLIENT_NODES=node-2, node-3 SERVER_NODES=node-4, node-5,node-6 ALL_NODES=$ADMIN_NODE,$CLIENT_NODES,$SERVER_NODES |
