Cloud-converged storage is here [63147]
By Nancy.Hart

Nancy blogs, "Cloud-converged storage is here. But, what does that mean to you?

Oracle ZFS Storage Appliance is cloud-converged storage because it is born in the Oracle Public Cloud where we deploy and test it before we ever ship it to a customer. With an 1 EB (yes, exabyte) deployed at Oracle, ZFS Storage Appliance is proven for extreme scale.

Oracle ZFS Storage Appliance is cloud-converged storage because a native cloud gateway, known as ZFS Cloud, seamlessly integrates on-premises storage with the public cloud. ZFS Cloud is a simple way to bridge the gap between on-premises and cloud resources that is completely transparent to your applications. Easy for your staff to manage all in one system.

Oracle ZFS Storage Appliance is cloud-converged storage because it is deployed in private clouds around the world with support for file, block and object protocols..."

Tips and Tricks for best RMAN Backup and Recovery Performance. The new and spectacular 60TB/h backup and the 62TB/h recovery rates with the all new ZS5-4 [62452]
By Patricio Zambrano

Patricio blogs, "Are you interested in improving your RMAN Backup and Recovery? Specifically, the Level 0 backups plus daily incrementals with your ZFS Storage Appliance? Is your current vendor not providing the floor space/performance/price/raw capacity that you need? Are you hungry? Then keep on reading!

Just as you would make the perfect finger licking Mexican Taco (Yes, I am from Mexico!), there is a way to ensure maximum RMAN performance with an Oracle ZFS Storage and an Oracle Engineered system(X6-2 server). Of course, the level of complexity is probably not the same but you get the idea ;)..."

Zero Copy I/O Aggregation [43366]
By Roch Bourbonnais

Roch writes, "One of my favorite feature of ZFS is the I/O aggregation done in the final stage of issuing I/Os to devices. In this article, I explain in more detail what this feature is and how we recently improved it with a new zero copy feature.

It is well known that ZFS is a Copy-on-Write storage technology. That doesn't meant that we constantly copy data from disk to disk. More to the point it means that when data is modified we store that data in a fresh on-disk location of our own choosing. This is primarily done for data integrity purposes and is managed by the ZFS transaction group (TXG) mechanism that runs every few seconds. But an important side benefit of this freedom given to ZFS is that I/Os, even unrelated I/Os, can be allocated in physical proximity to one another. Cleverly scheduling those I/Os to disk then makes it possible to detect contiguous I/Os and issue few large ones rather than many small ones..."
