The Headroom graph in SANtricity System Manager shows the remaining performance capability of the physical objects (e.g., disks, SSDs) in the storage system.
This helps in understanding how much additional load the system can handle before reaching its performance limits.
Reference: NetApp SANtricity System Manager User Guide, which explains the performance monitoring features.

I’m stuck between B and D. Both seem plausible!

D could be relevant, but B feels more accurate overall.

C seems off. It's not just about CPU, right?

I agree, B makes sense. It shows how much is left.

I think it's B. Remaining performance capability sounds right.

Surprised to see so many people think it's B, I had my doubts!
KA

I always thought it was about CPU usage, but B makes more sense.

Wait, I thought it was about I/O with the disk drives?

The Headroom graph? I thought that was just a fancy name for the storage system's ego.

Headroom? More like Deadroom, am I right? *ba dum tss*

Hmm, I'm torn between B) and D). Guess I'll just flip a coin and go with B).

D) sounds like the right answer to me. The Headroom graph represents the resources being consumed by a defined workload.

I'm pretty sure the Headroom graph is about the CPU usage, so I'll go with C).

B) is the correct answer. The Headroom graph shows the remaining performance capability of the physical objects in the storage system.

I thought it represented the overall performance capability, but I can't recall if it specifically mentioned physical objects or not.

I feel like the Headroom graph is more about the backend disk drives, but I could be mixing it up with another graph we studied.
LE

Ah yes, the Headroom graph! I remember this from the lecture. It represents the remaining performance capability of the physical objects in the storage system. Definitely option B.

I'm a bit stumped on this one. Is the Headroom graph showing the CPU processing capacity that's being used? Or is it the remaining performance capability? I need to review my notes on this.
AD

Alright, I got this. The Headroom graph shows the percentage of I/O associated with the backend disk drives. It's giving me a sense of the system's performance capacity.
PH

It's about the remaining performance capability of the system!
TW

I remember practicing a question similar to this, and I think it was about resource consumption. Could it be related to workload resources?
EL
Eleonore

I think the Headroom graph shows the remaining performance capability, but I'm not entirely sure if it's just for the physical objects or the whole system.
AR
Arlean

Totally agree, option B is the right one.
TO
Tori

A is tempting, but I lean towards B too.
OL

Okay, let me think this through. I'm pretty sure the Headroom graph represents the resources being used by the workload, not the CPU usage. But I'm a little confused about the backend disk drives part.
IZ

Hmm, the Headroom graph... I think it's showing the remaining performance capability of the system, but I'm not totally sure.
DA
Danilo

Definitely helps in understanding system limits!
DY
Dyan

Makes sense, especially for performance monitoring.
DE

I’m leaning towards option B as well.
NA
Nan
