NetApp filers consider this to be a legitimate configuration, even a
"supported and recommended one".  If I understand the documentation
correctly, NetApp will (somehow) remember the physical interface a
request arrived on, and make sure to its send replies out same.  It
sounds like a slight breakage of the expected behavior in order to
gain load-sharing for their multiple NICs attached to the same subnet.
 IIRC, you can turn the feature off if it makes an issue.

OEMs for X2 10G LAN PHY optics

2009-07-10 Thread Duane Waddle
Hi,

I am searching for opinions on OEMs of X2 form factor 10G LAN PHY
optics.  We've found that most router/switch vendors  mark these
particular items up significantly just to provide their own
sticker/EEPROM ID.  As such, we'd prefer if we can to procure from the
OEM (or their reseller).  Is this a situation where any company who's
a signatory to the MSA produces suitable modules, or are there
particular OEMs to prefer (or avoid)?

If it matters, the prime platform we're looking to plug optics into is
the WS-X6708-10G module for a 6500/7600.

Thanks in advance

Hi Paul,

Have you considered any of these?

[1] Request Tracker --  http://bestpractical.com/ -- Really nice open
source ticketing system

[2] Bugzilla -- http://www.bugzilla.org -- Another nice tool, built
more "for the programmer" then operations.  Used by Mozilla and Redhat
for their bug trackers.

[3] Atlassian JIRA -- http://www.atlassian.com/software/jira/ --
Commercial tool, also more developer-centric then operations-centric,
but should be easily adaptable to your needs.  Used by ASF many Apache
subprojects.  Atlassian recently changed their pricing model to
include 10 users for $10.

Of the three, I personally prefer JIRA -- to the point of setting up
one of the $10 systems to keep up with the honey-do list at home.

We've had lots of success with both APC and Baytech units.  A lot of
the Baytech units ONLY have RS-232.  Ditto on the mounting issues with
the vertical -- deeper and/or wider cabinets seem to reduce a lot of
the pain.  On our next buildout we're looking at the Panduit CS1
cabinets which are both deeper and wider.

Yes, a PIX/ASA would stop this cold.  The TCP state tracking would not
allow traffic to pass unless the whole 3-way handshake was observed by
the box.  Only recently did Cisco add features to make tracking the
TCP connection state optional.
(http://www.cisco.com/en/US/docs/security/asa/asa82/configuration/guide/conns_tcpstatebypass.pdf)
 The larger ASA-5580 machines can be virtualized into dozens (or more)
security contexts as needed.  I imagine it would take some effort to
figure out how to cleanly integrate such a configuration into a POP.
