I am pretty active on LinkedIn with the NetApp groups there, and newbie NetApp admins are asking quite often lately about the NCDA exam.
Here are some helpful things to try out on the simulator. Every netapp admin should know them.

I just wanted to share a cool bit of information about what one of our Riverbed Whitewater customers is getting as backup to disk and automatic redundancy to “the cloud”. This customer is using Backup Exec 2012, with the Whitewater appliance as a backup datastore.
This customer is storing 66.7 TB of stored data in 4TB of physical and cloud space and will be saving more than $7,000/month with cloud backups because of it!

First off, let me say that I live and breathe the terminal. Almost 2 decades playing in unix and linux gives me a strong love for it. I know I am more productive than a pointy clicky loser. BASH ftmfw! (and when I am stuck admin’ing windows systems, powershell, which I am not ashamed to say I have a newfound fondness for.)

A tale of debugging and tech support hell… don’t freaking buy an HBA with a server! Don’t REUSE cards you have laying around if they were sourced from any server manufacturer or different brand SAN.

I figured it was time to share some of the information I have posted before with graphing with powershell and also more advanced…
In the past, I had used 3D modeling in the Stats package R, to do 3D modeling of the CPU on a san. This is how!

Below is a step by step of how I was able to resize an existing pun and ASM disk to a new size.
Oracle recommends for ONLINE disk group space increase to actually create a NEW LUN, and add it to the existing disk group. There have been a few bugs w/ ASM recognizing. If you do wan’t to attempt the resize method, you can attempt the instructions below on a test system. Things like this are why I typically recommend NFS. No partitions, no filesystems, none of the issues.

I am constantly in new customer environments, setting up NetApp, Oracle RAC & ASM, NetApp SnapDrive, SnapManager for Oracle, etc on Linux…
While I know what I am doing in regards to storage and Oracle, most customers do not have a single point man (or woman) who knows all of these technologies and is the administrator to do day to day operations of them all. Also, when I have tried to teach the teams to do this, or if the DBA is in charge of all of these steps in a small environment, they typically get very confused when thinking about the relationship of the /dev/sd* and the multipath /dev/mapper/360* entries.

This is a presentation I gave with Chris from @SecEvangelism, at H.O.P.E 9, in NYC July 13 2012.
A dark and seedy journey to explain the real driver behind internet innovation, porn. How an economy built on the ultimate satisfaction just a click away has driven technological advances. Racy browsing habits involving our innermost secrets, vulnerable parties and criminal syndicates have driven malicious code and subsequent security advances. Broad ranging censorship involving much more than pornography has been the end result in attempts to reign in such “unhealthy” habits by good intentioned governments and organizations. Join us through the timeline of pornography on the internet, related security threats, an overview of industry economics (legal and ≈ illegal) and related censorship.
