When reviewing the actual protection output of N+4/2, what does the number “4” represent?
It's OneFS FEC protection nomenclature for our "hybrid" protection polices. More generally, it's
where "N" is the number of data stripe units in a stripe, "M" is the number of FEC stripe units in a
stripe, and "b" is the number of stripe units in a stripe which are allowed to reside on the same node.

In Isilon OneFS, what is a characteristic of CoW with snapshots?
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
Which OneFS networking option enables Isilon for DNS multitenant functionality?
Groupnets are designed to enable multi-tenant DNS support per access zone.
A company wants to re-use HD400 nodes into a new cluster with OneFS 8.2.0. What is the minimum
number of HD400 nodes required?
On which node does the SSIP initially reside?
An Isilon cluster has four H500 nodes. Data protection and access are set to N+1 and concurrency
respectively. How many drives will be used across the disk pool to protect a 1 MB file?
