2. Installing and Uninstalling
RoCE Driver for the OCe14000-Series Adapters
Uninstalling the Ethernet Driver Kit
Note: You must run the uninstall script that shipped with the version of the driver kit
you want to remove.
To uninstall the Ethernet driver:
1. Log in as “root”.
2. If possible, exit all applications that use Ethernet-attached drives, then unmount the
drives. If you cannot exit all applications that use Ethernet-attached drives, the
uninstall works properly, but you must reboot after the uninstallation is complete.
3. Run the elx_net_install.sh script with the “--uninstall” option:
./elx_net_install.sh --uninstall
RoCE Driver for the OCe14000-Series Adapters
RoCE is a network protocol that allows remote direct memory access over an Ethernet
network. RoCE is a link layer protocol that allows communication between any two
hosts in the same Ethernet broadcast domain.
Network-intensive applications like networked storage or cluster computing require a
network infrastructure with high bandwidth and low latency. The advantages of
RDMA over other network application programming interfaces are lower latency,
lower CPU load, and higher bandwidth.
The following operating systems are supported for RoCE:


RHEL 6.6 -- Native stack (inbox and OOB)
RHEL 7.0 - native stack (OOB only)
Installing the RoCE Driver
Supported RoCE drivers can be downloaded from the Emulex website.
