•Obtaining Documentation and Submitting a Service Request
Introduction
The SSI interface provides the following features:
•Network-based volume management (EMC Invista, Incipient iNSP)
•Network-assisted storage applications using SANTap
•Fibre Channel Write Acceleration (FC-WA) and SCSI flow statistics
•Network-Accelerated Serverless Backup (NASB)
•Data Mobility Manager (DMM)
•Secure Data Erase
Note As of NX-OS Release 4.1(1b), SAN-OS has been changed to NX-OS. References to SAN-OS releases before 4.1(1b) still apply.
System Requirements
This section describes the system requirements for Cisco MDS NX-OS Release 4.2(1j) and includes the following topics:
•Determining the Software Version
Components Supported
Table 1 lists the software and hardware components supported by the Cisco MDS 9000 Family.
Determining the Software Version
Note Use the latest available software release supported by your vendor for all Cisco MDS 9000 Family products.
To determine the version of the Cisco NX-OS software currently running on a Cisco MDS 9000 Family switch using the CLI, log into the switch and enter the show version command.
To determine the version of the Cisco NX-OS software currently running on a Cisco MDS 9000 Family switch using the Fabric Manager, from the Switches tab in the information pane, locate the switch using the IP address, logical name, or WWN, and then check its version in the Release column.
Downloading Software
To download the latest Cisco software, access the Software Center at this URL:

Note If you would like to request code to be provided under the terms of either GNU General Public License (GPL) or the GNU Lesser General Public License (LGPL), contact mds-software-disclosure@cisco.com.
If SSMs are present in a Cisco MDS 9000 Family switch, these upgrades may be performed as required:
•Upgrading a previously provided package
•Upgrading the SAN-OS image
•Reformatting the SSM add-on image
If you need additional information about installing or upgrading the SSM, refer to the Cisco MDS 9000 Family Storage Services Module Software Installation and Upgrade Guide.
New Features
This section describes the new features introduced in this release. For more information about the features listed, see the documentation set listed in the"Obtaining Documentation and Submitting a Service Request" section.
The SSI Release 4.2(1j) image is compatible with Cisco MDS NX-OS Releases 4.2(1a).
There are no new features in this release. SSI Release 4.2(1j) supports the EMC Invista application.
Limitations
This sections lists limitations or restrictions associated with this release.
Configuring SSM Ports in Auto Mode
Starting with Cisco MDS SAN-OS Release 3.0(1), the SSM front panel ports can no longer be configured in auto mode. Because auto mode is the default for releases prior to Release 3.0(1), you should modify the configuration of the ports before upgrading the SAN-OS software image to NX-OS Release 4.2(1j) to avoid any traffic disruption.
For information on how to reconfigure the SSM ports, refer to the "Reconfiguring SSM Ports Before Upgrading to NX-OS Release 4.2(1a)" section of the Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 4.2(1a).
Compatibility Matrix
Before upgrading your SSI image, refer to the Cisco MDS NX-OS Release Compatibility Matrix for Storage Service Interface Images, and to Table 11 in the MDS 9000 Family Release Notes for NX-OS Release 4.2(1a). Use Table 11 to determine your nondisruptive upgrade path to Cisco MDS NX-OS Release 4.2(1a).
Note If you are using SANTap in your environment, you cannot upgrade directly from SAN-OS Release 3.3.x to NX-OS Release 4.2. The only supported upgrade path for SANTap environments is from SAN-OS Release 3.3.x to NX-OS Release 4.1.x to NX-OS Release 4.2.
Caveats
This section lists the open and resolved caveats for Cisco MDS SSI Release 4.2(1j). Use Table 2 to determine the status of a particular caveat. In the table, "O" indicates an open caveat and "R" indicates a resolved caveat.

Resolved Caveats
•CSCtd56493
Symptom: When the data path processor (DPP) goes down, the first entry in an internal queue gets removed. As a result, the DPP might fail.
Workaround: This issue is resolved.
Open Caveats
There are no open caveats in this release.
