In Isilon OneFS, what is a characteristic of CoW with snapshots?
Correct Answer:
A
With copy on write, as the name suggests, a new write to HEAD results in the old blocks being copied out to the snapshot version first.
Although this incurs a double write penalty, it results in less fragmentation of the HEAD file, which is better for cache prefetch, etc.
Typically, CoW is most prevalent in OneFS and is primarily used for small changes, inodes and directories.

A company deployed an Isilon cluster that consists of eight nodes connected to a main production subnet by all available 10GB ports. Later, the company decided to implement a disaster recovery solution with a separate replication subnet. During the reconfiguration, one of the 10Gb ports from each of the nodes 1-4 was moved into the new pool and SBR was activated.
After activating the replication policies, the administrator noticed that the main production ports on nodes 1-4 reached the bandwidth limit. What is a possible reason for this behavior?
Correct Answer:
B
