8 Cool Projects found inside HP Labs

ComputerWorld took a tour recently of HP Labs to check out some of the things we're working on from the desktop to the datacenter.  We are really fortunate that we have these folks behind us.  What's even more fortunate for our customers is that these innovations find their way into real world products today.


Much of the Thermal Logic power and cooling technology in the BladeSystem and now Integrity and ProLiant servers is based on the ground breaking work of folks like Chandrakant Patel

Question: What does “receive path validation” do and what could be the reason for the failure?

This one of the methods used to provide fail over for network traffic. 


 


From our BladeSystem support staff


 

"This is just a “redundancy mechanism” that is part of the HP Teaming driver.Not trying to over simply things but here it goes. NIC A and NIC B are teamed together. NIC A is receiving frames okay, NIC B has not received any frames.Teaming driver sends “Test Frame” out NIC A, sets timers and waits for NIC B to receive it. This is repeated a few times.If NIC B still has not received a frame after a few intervals, it is determined the RX (Receive) Path to this NIC is broken, thus NIC is marked as “Receive Path Validation” and is removed as an Active member of the team. This is a good thing because we don’t want a NIC in the team that can’t hear… So…either there is a problem with that NIC receiving frames (fix it) or there is a problem in the Teaming driver detecting “false” RX Path failures.Either way the recommendation is never to disable it as a solution to the problem.

Learn more about Solid State Disks (SSDs)

With all the buzz about solid state disks (SSDs) you’d think it was a brand new thing. For over 25 years, technologies in the consumer world have been using solid state storage technology to improve how information is created and shared. information What’s new is the way business and technology trends are influencing the adoption of new solid state storage technology designs in the enterprise data center.

I ran across this website and a great tech brief about the good and bad of SSD technology so you can make up your own mind and decide if SSD is right for you.


 

How to order three-phase power module stand-alone for c7000!

Seems that we get a lot of questions on how to convert single phase power modules to 3-phase modules. Our technical staff tries to sum up the process.


 The problem:


"I have a partner who ordered a few enclosures with single-phase power per customer's suggestions.  Turns out customer now wants three-phase power.  The partner is looking to simply order the $175 three-phase power module stand-alone: 413380-B21.  They are unable to do so as it is an option to purchase only as an FIO orderable option with an enclosure on the HP site.  I know you can get the single-phase modules sent seperately and they've ordered those before.  Is there any way to do this for the three-phase module or a spare parts # to avoid a full return for a $175 part?"


 


Answer:


Converting a Single Phase c7000 Enclosure to 3-Phase Enclosure and a 3-Phase Enclosure to a Single Phase Enclosure.

 

To do a conversion the appropriate Spare Part number must be ordered through spares. In North America, Service Spares can be ordered through the HP Parts Store at http://h20141.www2.hp.com/hpparts/default.asp?EE=InvChr

 

Local spare parts stores and spares distributors for other regions can be found at http://h20141.www2.hp.com/hpparts/country_choice.asp

 

Use the table below to order the correct spare part to replace the original module.

 

Spare Part  Description                                                          Plug Type


413495-001  3-Phase North America/Japan Input Module       L15-30P


413496-001  3-Phase International Input Module                    IEC309, Red, 5-Pin, 16A


413494-001  Single-Phase Power Input Module                     C19 - C20 Cord

 

It is the responsibility of the user to ensure that the correct receptacles and/or PDU Infrastructure are available prior to the conversion.  For more information on powering c-Class enclosures please consult the c-Class Site Planning Guide available at http://h71028.www7.hp.com/enterprise/cache/499697-0-0-0-121.html


 


A brief overview of the steps required is below but consult the c7000 Maintenance and Service guide for detailed removal and replacement instructions, this is available at http://h71028.www7.hp.com/enterprise/cache/316682-0-0-0-121.html

 

1. Power Down the Enclosure


2. Disconnect all power cables to the enclosure


3. Remove the hot-plug Power Supplies from the front of the enclosure


    NOTE: The input module is difficult to remove if the power supplies are inserted in the enclosure.


4. Undo the 3 screws on the input power module at the rear of the enclosure


5. Remove the Input Power Module


6. Replace with the new Input Power Module


7. Tighten the 3 screws to lock the module in place


8. Replace the hot-plug power supplies


9. Add additional hot-plug power supplies if required


   Note: The 3-Phase Module requires 3 or 6 Power Supplies to operate, extra power supplies should be ordered if necessary.


10. Reconnect the power cables


11. Power the enclosure on

 

The user then needs to connect to the Onboard Administrator via Telnet or SSH and login to the command line interface as an administrator.


The following command should then be run to set the appropriate input module type.

 

Set enclosure pdu_type x


      x = 1 = Single phase


      x = 2 = Three phase North America/Japan


      x = 3 = Three phase, International


      x = 4 = DC Power

 

More details on the Onboard Administrator Command Line Interface are available at http://h71028.www7.hp.com/enterprise/cache/316682-0-0-0-121.html in the


1. HP BladeSystem Onboard Administrator User Guide


2. HP BladeSystem Onboard Administrator User Guide Command Line Interface User Guide


 


As the Input Power Module is a Field Replaceable Part there are no warranty or support issues with replacing this item.


 


Hope this helps all you power hungry BladeSystem people out there.


 

Mike Klayko, CEO of Brocade nailed it

I'm a sucker for unscripted honesty.  Kudos to Mr. K for taking a deep breath after Cisco's UCS and Project California grandstanding to put some reality in front of the rhetoric. In less than 3 minutes, he really boiled all the hype down and simply articulated what a lot of our customers and partners are thinking too. 


My takeaway: ROI on CapEx in 12 months or less means it's not about our grandious vision of tomorrow, it's about helping you implement your vision of your data center today.  Keep the forklift in the warehouse.
