#Performance comparison on the C-Series?

As you might know, the C-Series models will now become "R2" models. Are there any performance numbers out yet, especially compared to the "R1" model?

#

from what they told us in their webcasts, performance shouldn't be noticeably affected 😉 But I'm not aware of any hard numbers being published (yet?)

#

I mean they even removed the CPU infos from HWU, I think in the future we'll rather be seeing less hard performance numbers than more

It's a strange move... let's "handicap" the one product that sells the best... if the price difference to the A-Series wasn't that big I could understand it... Of cause I have two customer who have old A300's where we are planning to upgrade, but this is now stalled because of this announcement... we don't even know if the new C-Series is better than A300 with SAS SSDs... NetApp tend to forget that there are other customer who doesn't require a Datalake for their AI Inferencing 😉

yeah, it's annoying. They seem to think that they can sell more A-Series that way, but in reality it just drives customers away to other vendors, because as you say, 90% of customers don't need an A-series

will they? or will they only see higher CPU utilization at the same performance point? Remember, high CPU utilization is not a primary performance metric. In the end we'll have to wait and see until the systems are shipping

I think the worst thing about this is that NetApp has yet to explain the new R2 and it's performance potential (or lack of)... I have heard roumers that is's not much faster than an old A300 yet we don't know... They simply removed a very good selling product line and replaced it with something they cannot explain... Where is @cosmic warren when we need an online sesstion where someone at NetApp who can explain this new productline in details?

You would get lower latency when reading from an A300 though compared to a C-Series model. The A300 is TLC after all (yes, SAS-based which adds ~10-20% ms but still).

...but only if data is not already cached in RAM 😉

OK, but what is the point of creating such a large gab between system performance (and price)? We have customer which will just look at other vendors because of this... simply because the C-Series is most likely (we don't know yet) too "weak", but the A-Series is just 3 times the price which is out of the question... So it will most likely force customers to look at alternatives to NetApp...

# dry summit I would guess you are a technical (sales) guy - don't care too much about pricin...

I have been a NetApp consultant since F720 😉 For about 10 years ago I started my own little company which is also a NetApp partner, so I "have" to be the sales guy as well 🙂 And let me tell you that, yes in the short run, NetApp will help you if you have existing C-Series quotes, but after this help I think you are left with the "way too expensive for most customers" A-Series and the affordable C-Series will most likely be slower than the old SAS SSD's. (or we don't know yet)... I think the main "problem" here is not that NetApp limits this, because everyone does this (Pure Storage has done it for years), but the issue is more that there is a "huge" gab from the C to the A... so they might as well create an "B-Series" which fills this gab, or else customers will look elsewhere... but what do I know? I'm just a wannabe technical/sales guy 🙂 This wouldn't have been such a problem if they just did this performance cap. from the start... but here we are..

i totally agree, the timing is absolutely awful and should have been done with the launch or the next platform. They way it’s done is also absolutely dumb, hopefully time heals the wounds and we see a more aggressive pricing with A Series in the near future. I think the performance is still fine for many workloads and customers, it’s primarily the way of communication…

Also the nameing of r2. This means for me like revision 2 which should be „better“

as for the "other" R2 systems, well, there's not much of a ways to steer away from those, as the old r1 systems are hidden behind some very strict PVR processes

Most customers will likely not perceive much difference. The majority of customers do not drive the c platforms to maximum cpu utilization

#

Those that still be driving the c series to maximum cpu are the ones that really should be on a series anyway

@analog linden I do not agree completely. We now migrated our first FAS SnapVault systems to a C60 and the CPU is already at over 50%, even with only 55% usage of the Aggregates. I‘m not so confident migrating more on it and an A series is definitely an overkill. So from our end, we need to discuss if we want to move completely away from FAS to C

@rigid thistle Cannot argue. Like I said…most customers….
Clearly you may be in the upper echelon of use cases. Another thing may be that if you migrated, there may be some cpu overhead optimizing efficiencies in the new platform and that +50% may eventually calm down
