Yes, I am an employee of Commvault Systems. I thought that this was
known to everybody here and I apologize if I have led anyone to believe
otherwise.
Back to my humble opinion, there is nothing that I have read re:
Delphix that would qualify as marketing.
Let's agree that we disagree here.
I'm on this list to find solutions to real problems and to offer
advice where I can.
So feel free to expand on your product, what sets it apart? Why would
I implemented your product vs another?
Well, Commvault 11 is a full fledged backup suite which can backup most
of the popular databases, also has Oracle archiving, akin to Informatica
ETL, has internal build-in Work-Flow engine which can help with
combining different solutions, it supports many virtualization software
suites, like VMWare, Hyper-V or Citrix and works together with many
array vendors and SAN devices, Oracle ZFS Appliance being one of them.
Pure, HDS, 3Par, Dell VMAX, VNX, XTremIO, Equalogic and Compellent, as
well as the entire product line from NetApp are also supported. The
full list of supported arrays and features is available here:
http://documentation.commvault.com/commvault/v11/article?p=features/snap_backup/support_snapbackup.htm
Since Delphix is not a full backup product and it doesn't position
itself as one, that means that the customer would need an additional
backup suite to protect email servers, virtual servers, SAP HANA and
MaxDB. Delphix also doesn't have Oracle archiving which Commvault 11
does have:

If I'm cloning a 10T database, what is the footprint?
What do you mean by "footprint"? The "clone database" works by creating
read/write snapshot of the LUNs containing the database and mounting
them on the other machine. There are slight differences in performance
and storage consumption which depend on whether you're using OnTap, SRDF
or Pure. Here is the documentation for cloning Oracle databases:
http://documentation.commvault.com/commvault/v11/article?p=products/oracle/snap/t_ora_snap_restore_clone.htm
These are SAN snapshot based clones. Commvault can, of course, do a
classic rman "duplicate database", with or without the connection to the
target database. That is, actually, a very cool feature of Oracle 11GR2,
which is fully supported by Commvault. As a fully fledged backup
software suite, Commvault 11 is also a traditional MML which can be
fully utilized by RMAN. As such, Commvault can be used to protect both
ODA and Exadata:
http://www.oracle.com/technetwork/database/database-appliance/overview/protecting-oda-with-simpana-1674112.pdf
We even have a specialized backup solution, not rman based, which can be
used to copy database to AWS or Azure clouds.
We support all the database releases from 10G on. We can even protect,
but not clone using storage snapshot, Oracle 9i. Oracle 9i protection is
done using the traditional rman/libobk.so method.
Commvault doesn't have anything built for the data masking, which means
that if you need to protect your SSN's, addresses and phone numbers, you
will have to do it yourself. If data masking is the reason for buying
Delphix, then we don't have anything there - yet.
Have a great weekend, time for dinner

Enjoy your dinner.

Thank you Rob.
That is precisely what I am doing. Commvault can clone databases using
storage snapshots. We can also seed the cloud for AWS and Azure and
copy the database to the cloud. Commvault 11, the product formerly
known as Simpana, is a full fledged backup suite which supports
snapshots and cloning.

I'm my humble opinion, if others are willing to offer information on
cloning they are more than welcome to speak up. Otherwise if the only
expertise on the list is Delphix than that is what we get.
Might I suggest expanding you expertise to other cloning technologies
and offering advice.
Just the view from my hangar.

Hi Tim,
How many other tools were mentioned on this group, as a possible cloning
solution? How many times was Delphix mentioned during the last few
months? I am not attempting to control anything, I am just warning the
readers of this group about the marketing. There is a simple truth:
there are other solutions for cloning databases, which deserve some
mention, with different strengths and weaknesses. Yet, for some reason,
only Delphix is regularly offered as a cloning solution on this group.
