Thin Cloning of PDBs is a Snap with Oracle Storage [40821]
By Bryce Cracco

Bryce Cracco writes, "I thought I'd bring up another integration point between Oracle ZFS Storage Appliance and Oracle Database 12c with Oracle Multitenant. Specifically, I want to discuss how we integrate our ZFS snapshot technology with Oracle Multitenant to reduce database storage footprint and speed database provisioning straight from the SQL Plus command line.

Oracle Multitenant option for Oracle Database 12c introduces the concept of the pluggable database (PDB), which exist within a container database (CDB). This is the basic construct that is used to facilitate database creation in multitenant environments from either 'seed' PDBs (essentially a template) or a 'source' PDB (an existing, running, full database). In either case, a simple SQL Plus command 'create pluggable database' is used to easily create the new PDB. Under the covers, the way this normally works is by duplicating the relevant files associated with the source or seed PDB, copying them to a new location to support the new PDB..."

ZFS: Doing It Right [40709]
Rock ZFS, Rock Your Performance Review

Imagine you're a system administrator, and an email arrives from your boss. It goes something like this:

"Hey, bud, we need some new storage for Project Qux. We heard that this [insert major company here] uses a product called the Oracle Sun ZFS Storage Appliance as the back-end for their [insert really popular app here]. We want to do something like that at similar scale; can you evaluate how well that compares to XYZ storage we already own?"

So you get in touch with your friendly local ZFS sales dudette, who arranges a meeting that includes a Sales Engineer to talk about technical stuff related to your application. The appliance, however, has an absolutely dizzying array of options. Where do you start?...

ZFS Data Encryption [40582]
Secure, Flexible and Cost-Effective

Part 2: How to Prevent the Next Data Breach with Oracle ZFS Storage Appliance Encryption and Key Management

John Szlendak blogs, "As we discussed in Part 1, storage system (or data-at-rest) encryption provides the best level of protection against data breaches and theft as it secures all your stored data independent of the network or the application environment. The Oracle ZFS Storage Appliance Encryption is one of the best storage encryption solutions out there. It provides highly secure, most flexible and cost-effective storage encryption and key management on the market. Here are some highlights..."

Sequential Resilvering [40581]
By Roch Bourbonnais

Roch writes, "In the initial days of ZFS some pointed out that ZFS resilvering was metadata driven and was therefore super fast : after all we only had to resilver data that was in-use compared to traditional storage that has to resilver entire disk even if there is no actual data stored. And indeed on newly created pools ZFS was super fast for resilvering.

But of course storage pools rarely stay empty. So what happened when pools grew to store large quantities of data ? Well we basically had to resilver most blocks present on a failed disk. So the advantage of only resilvering what is actually present is not much of a advantage, in real life, for ZFS..."
