# SPDK nvmf_tgt test plan
|
|
|
|
## Objective
|
|
The purpose of these tests is to verify correct behavior of SPDK NVMeOF
|
|
feature.
|
|
These tests are run either per-commit or as nightly tests.
|
|
|
|
## Configuration
|
|
All tests share the same basic configuration file for SPDK nvmf_tgt to run.
|
|
Static configuration from config file consists of setting number of per session
|
|
queues and enabling RPC for further configuration via RPC calls.
|
|
RPC calls used for dynamic configuration consist:
|
|
- creating Malloc backend devices
|
|
- creating Null Block backend devices
|
|
- constructing NVMe-OF subsystems
|
|
- deleting NVMe-OF subsystems
|
|
|
|
### Tests
|
|
|
|
#### Test 1: NVMe-OF namespace on a Logival Volumes device
|
|
This test configures a SPDK NVMe-OF subsystem backed by logival volume
|
|
devices and uses FIO to generate I/Os that target those subsystems.
|
|
The logical volume bdevs are backed by malloc bdevs.
|
|
Test steps:
|
|
- Step 1: Assign IP addresses to RDMA NICs.
|
|
- Step 2: Start SPDK nvmf_tgt application.
|
|
- Step 3: Create malloc bdevs.
|
|
- Step 4: Create logical volume stores on malloc bdevs.
|
|
- Step 5: Create 10 logical volume bdevs on each logical volume store.
|
|
- Step 6: Create NVMe-OF subsystems with logical volume bdev namespaces.
|
|
- Step 7: Connect to NVMe-OF susbsystems with kernel initiator.
|
|
- Step 8: Run FIO with workload parameters: blocksize=256k, iodepth=64,
|
|
workload=randwrite; varify flag is enabled so that FIO reads and verifies
|
|
the data written to the logical device. The run time is 10 seconds for a
|
|
quick test an 10 minutes for longer nightly test.
|
|
- Step 9: Disconnect kernel initiator from NVMe-OF subsystems.
|
|
- Step 10: Delete NVMe-OF subsystems from configuration.
