9 iSER Configuration
This chapter provides procedures for configuring iSCSI Extensions for RDMA
(iSER) for Linux (RHEL and SLES) and VMware ESXi 6.7, including:
 Before You Begin
 “Configuring iSER for RHEL” on page 189
 “Configuring iSER for SLES 12 and Later” on page 192
 “Using iSER with iWARP on RHEL and SLES” on page 193
 “Optimizing Linux Performance” on page 195
 “Configuring iSER on ESXi 6.7” on page 196
Before You Begin
As you prepare to configure iSER, consider the following:
 iSER is supported only in inbox OFED for the following operating systems:
 RHEL 8.x
 RHEL 7.6 and later
 SLES 12 SP4 and later
 SLES 15 SP0 and later
 VMware ESXi 6.7 U1
 After logging into the targets or while running I/O traffic, unloading the Linux
RoCE qedr driver may crash the system.
 While running I/O, performing interface down/up tests or performing cable
pull-tests can cause driver or iSER module errors that may crash the
system. If this happens, reboot the system.
