8. How does SnapShot work in NetApp?
Ans:
NetApp’s SnapShot technology takes point-in-time images of a file system, capturing its state. But instead of copying the actual data, SnapShot leverages a technique where only the changes or “deltas” since the last SnapShot are stored. This makes SnapShots extremely space efficient. When a user accesses data from a SnapShot, NetApp uses a combination of the original data and the changes stored in the SnapShot to present the data as it appeared at that specific point in time.
9. What is the significance of NVRAM in NetApp?
Ans:
NVRAM, which stands for Non-Volatile Random Access Memory, plays a critical role in NetApp systems by logging all write operations. Before data is written to the disks, it’s first logged to NVRAM. This ensures that even if there’s a system failure before the data is committed to the disks, there’s a persistent record of those operations. Once the system is restored, the logged operations in NVRAM can be replayed, ensuring data integrity and consistency.
10. What is Deduplication?
Ans:
In data storage, deduplication is the process of locating and removing redundant copies of data in order to maximise storage efficiency. For instance, if multiple users store the same file, deduplication ensures that only one unique instance of that data is stored, with all other references pointing to that single copy. This process can significantly reduce storage needs, especially in environments where redundancy is high, like virtualized systems or backup archives.
11. What is Thin Provisioning?
Ans:
Thin provisioning in data storage refers to the practice of allocating storage capacity dynamically to applications on an as-needed basis, instead of pre-allocating a fixed amount of storage in advance. This means storage is consumed only when data is written, optimizing utilization. By overcommitting storage in this manner, organizations can achieve better efficiency and flexibility, reducing costs and wastage associated with unused storage space.
12. How does NetApp ensure high availability?
Ans:
NetApp ensures high availability primarily through its Clustered Data ONTAP (cDOT) architecture.
