Supported Storage¶
Omnia v2.1 supports the following Dell storage platforms for shared filesystems and persistent volumes.
Storage support matrix¶
| Platform | Version | Protocol | Notes |
|---|---|---|---|
| Dell PowerScale (Isilon) | OneFS 9.x | NFS, SMB | Scale-out NAS; ideal for shared home directories and scratch filesystems. Omnia configures NFS client mounts on cluster nodes. |
| Dell PowerVault ME5 | ME5 Series | iSCSI, FC, SAS | Block storage; suitable for databases, boot volumes, and high-IOPS workloads. Omnia configures iSCSI initiators on target nodes. |
PowerScale (OneFS) integration¶
| Parameter | Description |
|---|---|
| OneFS version | 9.x (9.4 or later recommended) |
| Access zone | Configure a dedicated access zone for HPC exports to isolate permissions and authentication. |
| Protocol | NFS v3 or NFS v4.x -- configured in storage_config.yml (see Storage Config). |
| Authentication | Local, LDAP, or Active Directory. Must match the cluster authentication method configured in security_config.yml. |
| SMB support | Supported for Windows or mixed-OS clients. Not used by default in Omnia HPC deployments. |
Note
Omnia mounts PowerScale NFS exports on cluster nodes using the mount
parameters specified in storage_config.yml. The PowerScale cluster
itself must be configured and operational before running omnia.yml.
PowerVault ME5 integration¶
| Parameter | Description |
|---|---|
| Series | ME5012, ME5024, ME5084 |
| Protocol | iSCSI (default for Omnia integration), Fibre Channel, SAS |
| Volumes | Pre-create LUNs and map them to host groups before running Omnia storage playbooks. |
| Multipath | DM-Multipath (device-mapper-multipath) is recommended for redundancy and load balancing. |
| Configuration | storage_config.yml specifies the PowerVault management IP, volume mappings, and mount points. |
