SSP Software Versions |
|
8 Nov 2001 |
This document (last modification on Nov 7th 2001) provides an overview of the
major differences between several SSP versions. It should ease the SSP
upgrade decision.
Before upgrading the SSP Software, it is required to read and understand the
SSP Installation Guide to ensure system uptime and supported SSP setup.
Depending on your environment, it's always recommended to use the newest
version of SSP Software, which can be downloaded from:

------------------------+---------------+---------------+----------------+
a) Solaris 7 needs KJP 106541 rev >= 17 and patch 111422 (libnvpair patch)
installed.
b) Solaris 8 < 7/01 needs patch 110945 (syslogd patch) rev >= 02 installed.
c) For more then 8 domains you must not use a SS5 as SSP.
d) Minimum Hardware Requirement for a SSP: 2.1 GB Disk
170 MHz Processor
64 MB Memory
512 MB swap
e) For OpenSSP r) Minimum Requirement in case of SSP 3.5 see 806-7615 Chapter 2
(Sun Enterprise 10000 SSP 3.5 Installation Guide and Release Notes).
f) Solaris 8 10/01 in conjunction with DR model 3.0 needs to run SSP 3.5.
g) If you use features like ADR or dual grid power option, both the Main and
the Spare SSP must be running the same SSP Version.
h) For more information see bug 4218687.
i) Requires Patch 105029 on the domain.
j) If all domains are running AP 2.3 or AP 2.3.1 you can safely remove the
SUNWapssp package on the SSP. If you use an older Version of AP on any
domain, you have to leave the package on the SSP.
k) Requires Patch 105356 (ssd patch) rev >= 08 on the domain.
l) Requires Patch 107458 (ssd patch) rev >= 09 on the domain.
m) Requires Patch 109524 (ssd patch) rev >= 01 on the domain.
If your domain is running the Solaris 8 operating environment, you must use
Alternate Pathing software version 2.3.1.
n) IDN (InterDomain Networks) allows you to connect your domains via high-
speed, hardware connection. The 11/99 release of the Solaris 7 operating
environment is the first Solaris release to support the IDN feature. IDN
is supported starting in SSP version 3.2. For more info see 806-5222 (Sun
Enterprise 10000 InterDomain Networks User Guide).
o) ADR (Automated Dynamic Reconfiguration) enables you to automate DR
operations like attaching, moving or detaching system boards.
p) It's understood having a 2nd SSP for the SSP failover or rather a 2nd CB
for the CB failover. Three Ethernet connections on the SSP are required
for a "Three-Subnet Network Configuration". Check the appropriate "Sun
Enterprise 10000 SSP x Installation Guide and Release Notes" for details.
q) Two new properties force_dtag_parity_mode and no_dtag_ecc_ce_scrub are
added, see man page of postrc for more details.
r) OpenSSP means that a SSP Workstation or Server can run third-party software,
provided that the SSP meets the OpenSSP resource requirements. For more info
see 806-7615 (Sun Enterprise 10000 SSP 3.5 Installation Guide and Release
Notes).
s) DR model 3.0 is available in Solaris 8 10/01 and is consistent with the DR
functionality provided on other new Sun server lines. DR model 3.0 inter-
faces with the RCM (Reconfiguration Coordination Manager) and needs to run
SSP 3.5. The older version DR model 2.0 is compliant with SSP 3.2, 3.3, 3.4
and 3.5.
t) MPxIO (Multiplexed I/O) User and Installation Guide is available on Sun
Network Storage Solutions website (http://www.sun.com/storage/san).
Some older SSP versions
-----------------------
SSP 3.1.1
- has been EOL'd. Can no longer be ordered and is no longer shipping (Nov 1st 2001).
SSP 3.2
- has been EOL'd (Feb 28th 2001).
- its matrix is almost the same as for SSP 3.3 with the following notable
differences:
- supports just 8 domains.
- new features released: IDN, clock ratio 1:5 and 1:6.
- supported SSP Version on a Spare SSP: 3.1, 3.1.1 and 3.2.
If you use one of the new features released, both the Main and the Spare
SSP must be running the same SSP version.
