vmworld 2013

 VMWare introduces NSX (network virtual) similar to ESX(enterprise)

Fundamental piece of observation

Cisco = hardware money + free software
vmware = software money + free hardware (esxi, now nsx)

Interesting points to ponder

• VMWare is more general purpose platform unlike MS and Oracle where they are more of specific narrow application for storage in virtualization
• A total of 50 Billion IT market opportunity is explored in SDDC
• Software defined ???
• compute
• storage
• network
• sexurity

Hyper cloud

• A piece of RAM with ~780GB of server memory for data center infrastructure 

VSAN

• Nutanix

Java best practice queued datastructure

http://www.javacodegeeks.com/2010/09/java-best-practices-queue-battle-and.html


Came across this excellent article on comparison benchmark on famous queue datastructure in java collection.

Problem 
I ran into an issue of producer producing faster than consumer in my java LinkedBlockingQueue due to network IO on my consumer, i could not solve this problem as the difference in time over a period of time causes a significant delay.

Solution
My theoretical solution to this problem is to solve by setting a threshold on my queue and functionally drop some repetitive producer which is feasible in my application.

Priority, Delays, and Other Details

There are multiple queue classes in the java.util.concurrent package that implement the BlockingQueue interface

• SynchronousQueue: A hand-pattern. Producer(s) block until there is a consumer available; consumer(s) block until there is an enqueued message.
• ArrayBlockingQueue: Similar to the SynchronousQueue, except the queue can contain a pre-set number of items before the queue producer(s) block on queue insertion.
• DelayQueue: Elements placed in the queue are not available for removal until their delay time has expired. Items that are furthest past their expiration time are available for removal first. Calls to put() do not block since this queue is unbounded, although calls to take() will block until an expired message is available.
• LinkedBlockingQueue: Similar to an ArrayBlockingQueue, but where queue growth is allowed. However, the queue constructor does accept an optional parameter to constrain the growth to a maximum number of items.
• LinkedTransferQueue: Similar to SynchronousQueue, except the queue is unbounded in size and calls to put() never block. Calls to take(), however, will block until a queued item is available for removal.
• PriorityBlockingQueue: Similar to SynchronousQueue, except the queue is unbounded in size and calls to put() never block. Calls to take(), however, will block until a queued item is available for removal, and those items are subject to priority-based ordering. Enqueued objects must be comparable, meaning they must implement the Comparable interface and required methods.

Deep dive cisco nexus 1000v

I attempting to install N1Kv in my testbed to play around with it. I come with a CCNA and CCNP background( although been a while 5 some years ago)

My first impression was it was not that easy. I have been struggling with their hard resource requirement and installation requisite's.

My goal is to install a standalone N1Kv switch in my 4 x 2.83 ghz , 8GB mem.

Got it after meddling down for a week, installed a PRI and SEC HA VSM
Yet to get the VEM communicate with the VSM, my VSM could not reach the VEM.

• Layer 3 is the most suggested and easier way to make the control communication.

Update 9/24/2013
I have a working project hosted
 http://code.google.com/p/cisconetconftool/

Install ESXi from USB

1. Download ESXi from VMWare
2. Download UNetbootin from Sourceforge
3. Plug your USB drive into your computer.
4. Double click on the downloaded exe file. UNetbootin is a stand alone executable. No installation is needed.
5. Select the second radio button, Diskimage. Click the button with the ellipses on it, browse to and select the ESXi iso you just downloaded.
6. Once UNetbootin is finished, remove your USB drive from your current system. Plug it into the computer you want to install ESXi onto, restart the system and you are off and running. Everything will work just as if you were installing from any other media.

Quick pointer to Cisco N1K

Running into difficulties with installation keeping me awake at nights.

Excellent writeup on VEMCMD internals

Most of these can be seen from running a ‘vem-support all’ on a host, but I wanted to have a good reference point for my self.
