NetApp provides features such as SATA disks, Flash CacheRAID-DPthin provisioning, Snapshot copy, deduplicationdata compressionSnapVaultSnapMirrorFlash Pool aggregate, and FlexClone, which help achieve significant improvements in storage utilization.

The Storage Partitioning feature lets hosts with different operating systems share access to a storage array. Hosts with different operating systems that share access to a storage array are called “heterogeneous hosts.”

The Volume Copy feature creates a complete, independent physical copy of a data volume by creating two separate volumes, the source volume and the target volume, on the same storage array. Volume copy performs a byte-by-byte copy from the source volume to the target volume; therefore, the data on the target volume is identical to the data on the source volume.

What is a Consistency Point, and why does NetApp use it?

Understanding the write process in Data ONTAP.

A storage controller has two separate memory buffers for storing write data. The size of these buffers is based on the amount of nonvolatile RAM (NVRAM) in a given system. This can be calculated as 1/2 the NVRAM size for stand-alone systems or 1/4 the NVRAM size for clustered systems. All writes into a storage controller are stored concurrently in the following locations:

  1. Local memory buffer
  2. Local NVRAM/NVMEM
  3. Remote NVRAM (Clustered systems only)

As soon as the process to log to NVRAM is confirmed, the controller acknowledges the write as completed to the client machine (app, protocol?). At pre-defined triggers, this buffered write data is processed from the storage controller memory through the Write Anywhere File Layout (WAFL) and RAID layers and written to disk. The active file system pointers on the disk are not updated to point to the new locations until a write is completed. Upon completion of a write to disk, the contents of NVRAM are cleared and made ready for the next batch of incoming write data. This act of writing data to disk and updating active file system pointers is called a Consistency Point (CP). During the writing phase of one memory buffer, the second memory buffer and NVRAM space ( both local and remote ) are used to store and acknowledge incoming writes.
