Hey, look!

It's the semi-moribund datacenter ops list!

Nothing's happening in datacenters anymore, eh?   Damn AWS.  :-)

To remind everyone this list (which isn't mine) is here, let me toss four
URLs over the transom, for the benefit of those who haven't run across them.

If you run a datacenter, you should probably keep an eye on:

  https://www.datacenterknowledge.com/

and

  http://www.telecomramblings.com/

Both are industry blogs which take different approaches to the space;
the former is about the stuff inside the walls, and the latter more 
about how you connect them to the people who matter.

===

For keeping track of when those links and services break, check out
the Outages mailing list and wiki:

  http://wiki.outages.org

We have a pretty decent collection of system status pages, along with
links to fiber and undersea cable maps, and other useful resources,
and our mailing lists, and contributions are always cheerfully accepted.

The Verge article about Verizon's Sandy Cleanup Efforts in Manhattan

Et al,

I got some Copper going cheap… ;^(

I saw this on Reddit.... I figured I'd share it here too since no one else did.

A password is like a... toothbrush  ;^)

Choose a good one, change it regularly and don't share it.

Security Survey: Please Participate



SwiftpageEmail

 

 

Arbor Networks would like to invite you to participate in our annual Infrastructure Security Survey - a survey of service providers, enterprises, government agencies, universities and other network operators around the world.

The purpose of the survey is to gauge and report on general security issues, practices, procedures and observations from the industry. All data gathered from the survey will be compiled in the aggregate and published as Arbor’s 8th annual infrastructure security report and accompanying presentations. Individual responses are treated anonymously and no respondent names will appear in the report or presentations. As a reference, you may access a copy of our 7th annual report here:
http://pages.arbornetworks.com/rs/arbor/images/WISR2011_EN.pdf

To participate in this year's survey, please click on the following link:
http://www.arbornetworks.com/survey/ISR2012. You will be directed to a secure (SSL) connection to begin. The survey should take 30 minutes or less to complete. Survey completion by September 28, 2012 would be greatly appreciated.   

 

Thank you very much for your consideration. Please feel free to contact me at cmorales-rd7evPjynkNeoWH0uzbU5w@public.gmane.org should you have any questions on the survey or Arbor Networks.

Inside DCs

We all know that there are some concerns that are important to you if you're
operating -- or operating in -- an outside data center, like a colo.

Are there any specific considerations that are important to you in the 
reverse situation: things that matter to a corporate DC but not to a 
commercial one?

One specific point: anyone got any comparative safety information for
diesel vs LPG fueled gensets?  (80-100KW range)

Cheers,

Extreme Networks' latest switch

Hi!

Anybody have any experience with Extreme Networks' latest switch, the BlackDiamond X8?

They state it takes up one-third of a data centre rack and has a switching capacity of over 20Tbps,

or 1.28Tbps per slot. It can support 768 wire-speed 10G Ethernet ports.

Ephesians 4:32  &  Cheers!!!

proximity/HID card system recommendations?

Datacenter Ops!


We're looking at integrating our multiple datacenters' door lock / badging systems into a single system. We use HID proximity cards everywhere, so it needs to work with those (and hopefully some generic readers?). We're after something that is hierarchical, that has a centralized control point, that then pushes configs to the controllers that manage each facility. Of course it all needs to be IP enabled. We are very much interested in do-it-yourself, as the "integration and installation" quotes from the vendors we've seen tend to be astronomical.

Anybody have any experience on this that they'd like to share?

Thanks!
Randal

General opinions about AC cooling..

What do you guys think about ditching crac units and raised flooring?

 

We’re still in the planning stages of building out a new Data Center. 

Since we are going for a Busway system for power, the only need for raised flooring would be AC units.

We talked about doing in row AC units, but are now leaning more to redundant commercial units, like Trane 30’s.

Mainly the reason being outside air economizers, and other options that can be built in from the factory.

I would guess as long as the filtration is good, there shouldn’t be any issues with the halon system or particles.

 

I don’t see any issues with this setup, but would like to hear opinions from both sides if possible.

 

Sincerely,

Cacti / APC PDUs and Fibrechannel

I've set up Cacti for my new colo install, and mostly, it seems to be working
out pretty well for me.  I've got a couple of ACP 7841 PDUs though, that I'd
like to monitor the current draw through, and I can't seem to come up with 
a working template.  Anybody got one?

In a related story, has anyone got any good pointers to HOWTOs on setting up
FC-AL loops?  I've got adapters in all my machines, and I'd like to move my
Openfiler traffic from my 2960s over to that loop (I had an EMC24 switch I 
bought surplus, but it appears to be zorched).

And if I *do* move that traffic there, how would I measure it?

(Well, it's Datacenter 101 for *me*... :-)

Cheers,

Request for participation - Arbor 2011 Worldwide Infrastructure Security Report.


[Apologies if you've already seen this announcement in other forums.]

Request for participation - Arbor 2011 Worldwide Infrastructure Security Report. 

-----

Folks,

We're in the process of collecting survey responses for the 2011 Worldwide Infrastructure Security
Report (WWISR); this is the Seventh Edition of the Report, and we'd really be grateful for your
participation!  This is the only security-focused survey we're aware of which is specifically oriented
towards those who design, build, operate, and defend public-facing network
infrastructure/applications/services, and provides an opportunity to share your experiences and
perspectives with your peers within the operational community, as well as to benefit from their shared
experiences and perspectives.

The 2011 Infrastructure Security Survey is up and available for your input.  You can register and complete
the survey via this URL, which will redirect your browser to the survey tool (the survey itself is accessed
via http/s):

<http://www.arbornetworks.com/survey/ISR2011>

Once again, we've added several insightful questions from past participants.  Survey collection will end
as soon as we've reached the desired number of respondents (ideally, 100+).

The survey results will be published in the 2011 Worldwide Infrastructure Security Report during January
of 2012.  Also, please note that *no* personally- or organizationally-identifiable information will be
shared in any manner.

The 2010 edition of the Report is available here (registration required):

<http://www.arbornetworks.com/report>

Thanks in advance!

Starline Busway power distribution

Since Tom Walsh mentioned this in one of his posts, we’ve been looking into the system.

Does anyone know of any competitors or similar power distribution systems out there?

40G/100G for enterprise data centers

For an article I'm writing for Network World, I would be grateful to
interview network architects as to how (or whether) 40G and/or 100G
Ethernet will change enterprise data centers and/or enterprise campus
networks.

Interviews can be with or without attribution, and can be conducted over
email or phone.

Please contact me offlist if interested. Thanks in advance.
