Before using NVMe over RoCE, review the controller, host,
and recovery restrictions.
About the hardware
NVME over RoCE can be configured for the DE6000H or DE6000F 64GB
controllers. The controllers must have 100GB host ports.
Restrictions
The following restrictions are in effect for the 11.60.2 release.
See the Lenovo Interop Matrix for a complete
list of requirements.
Controller restrictions
- This protocol can be
used only for DE6000H or DE6000F controllers. A minimum of 64 GB of
physical memory is required to use the protocol on DE6000H or DE6000F
controllers. If the minimum memory requirements for the controllers
are not met during start of day operations, a message is displayed
that helps you diagnose the problem.
Switch restrictions
Attention: RISK OF DATA LOSS. You must enable Priority Flow Control
or Global Pause Control on the switch to eliminate the risk of data
loss in an NVMe over RoCE environment.
Host, host protocol,
and host operating system restrictions
- The host must be running
SUSE Linux Enterprise Server 12 SP5 or later system. See the Lenovo Interop Matrix for a complete list of requirements.
- For a list of supported
host channel adapters see the Lenovo Interop Matrix.
- In-band CLI management via 11.50.3 SMcli is not supported in NVMe-oF
modes.
Storage and disaster
recovery restrictions
- Asynchronous and synchronous
mirroring are not supported.
- Thin provisioning (the
creation of thin volumes) is not supported.
