I’ve been busy reading and testing everything I can with Delphix, whenever I get a chance.  I’m incredibly fascinated by copy data management and the idea of doing this with Exadata is nothing new, as Oracle has it’s own version with sparse copy.  The main challenge is that Exadata’s version of this is kind of clunky and really doesn’t have the management user interface that Delphix offers.

There is a lot of disk that comes with an Exadata, not just CPU, network bandwidth and memory.  Now you can’t utilize offloading with a virtualized database, but you may not be interested in doing so.  The goal is to create a private cloud that you can use small storage silos for virtualized environments.  We all know that copy data management is a huge issue for IT these days, so why not make the most of your Exadata, too?

With Delphix, you can even take and external source and provision a copy in just a matter of minutes to an Exadata, utilizing very little storage.  You can even refresh, roll back, version and branch through the user interface provided.

I simulated two different architecture designs for how Delphix would work with Exadata.  The first was with standard hardware, with Virtual Databases, (VDBs) on the Exadata and the second having both the Dsource and the VDBs on another Exadata.

VDBs On A Second Exadata

  • Production on EXADATA,
  • Standard RMAN sync to Delphix
  • VDBs hosted on EXADATA DB compute nodes
  • 10Gb NFS is standard connectivity on EXADATA

VDBs on Standard Storage, Source on Exadata

  • Production on EXADATA, standard RMAN sync to Delphix
  • VDBs hosted on commodity x86 servers

How Does it All Work

Now we need to capture our gold copy to use for the DSource, which will require space, but Delphix does use compression, so it will be considerably smaller than the original database it’s using for the data source.Screen Shot 2016-03-07 at 5.55.57 PM

If we then add ALL the VDBs to the total storage utilized by that and by the Dsource, then you’d see that they only use about the same amount of space as the original database!  Each of these VDBs are going to interact with the user independently, just as a standard database copy would.  They can be at different points in time, track different snapshots, have different hooks, (pre or post scripts to be run for that copy) with different data, (which is just different blocks, so that would be the only additional space outside of other changes.)  Pretty cool if you ask me!

Save a server, save space and your sanity, clone with Delphix.

While chatting on slack the other day, one of my peers asked if I’d seen that ESG Global had done a write up on Veritas Velocity.  Velocity is a product that won’t be available until the end of 2016 and is considered “Alpha”.  I was surprised that anyone allowed to participate in Alpha was able to publish a description on the product, but that’s not my call to make.

What I found interesting about the article, written by ESG, discusses how Veritas Velocity, “… is combining its sophisticated approaches to data management with its broader ability to deliver superior data protection and information availability in order to offer something revolutionary.”

Revolutionary?

I found this statement to be quite odd, as what they’re doing is simply using the same technology that Delphix has utilized for years to perform what Delphix has implemented at our customer sites since 2008.  They are simply hopping on the bandwagon, (along with a number of other companies) in an attempt to take advantage of the newest buzz word, “Copy Data Management”.

There’s nothing revolutionary about what we do.  It was revolutionary back in 2008 and may be seen as revolutionary to the customers who haven’t embraced the power of virtualized environments yet, but to say what they’ve created is revolutionary isn’t true.

If we inspect (at a high level) what Veritas Velocity does:

  1. A self-contained VM appliance to manage storage and thin cloning.
  2. A configuration of storage with an NFS mount presented as VMs.
  3. Hybrid management to the cloud.
  4. The VMs are then presented as targets to be used for thin clones.
  5. Eliminating copies of data by virtualizing database environments, focused on the cloud.
  6. A User interface to manage it all.

I can replace the lead into the above list with Delphix and that describes the Delphix Engine, as well.  We also offer a mature User Interface, advanced scripting capabilities and heterogenous support.

There are a lot of companies out there making claims that they have revolutionized new capabilities like “data virtualization”,  “copy data management “ and “test data management”. Delphix has been in this space since the beginning and as the Gartner reports prove, will continue to be the driving force behind what other companies are striving to achieve in their products.
