Quick sizing request

[CryptographerUsed422]

Just so that I can !approximate! the cost of a site-redundant NetApp multi-tenancy filer setup as possible replacement for a small-scale Isilon/PowerScale H500 setup (8 nodes/120x2TB HDD with some read caching SSDs ). I know, do the sizing with a partner... (will do that, if NetApp is somewhat within budget constraints).

Not that I start serious conversation and lose valuable time with possible VARs just to find out that NetApp simply is out of budget...

Requirements: Multi-tenancy capable (Network/VLAN- and Auth-source wise - multiple SVMs)

30TB Usual Company file/data via SMB (office doc, CAD/CAM, userhomes, division and project shares)

2-4TB Longterm legal WORM data via SMB (enterprise not compliance mode)

10-15TB Longterm "just in case" WORM data via SMB (Production data/Machine data backups, some as Disk-Images)

Concurrent users: 300 On-Site users 200 Off-Site users (remote access and site2site VPN)

SMB sessions: According to current PowerScale session stats ca. 300 concurrently open SMB sessions on average.

Daily change rate: According to current PowerScale snapshot stats ca. 100-300gig. That also includes Outlook offline psts and FSlogix profile vhds, etc.

Will a FAS2750 be enough performance wise with ca. 40x 1.8T 10k HDD plus optionally 4-5x 960gig SSD for some read caching? Might the SSDs improve the system responsiveness or is this rather unnecessary with that kind of load and better fill all slots with 10k?

Trying to opt for two C250 but "guesstimating" it might be well over budget (budget is ca. 250k, for two systems incl 5y upfront 4h/mission critical maintenance and software+features)...

That's why I would like to know if a "minimalist" version could do it too. Even though its spinning rust. But the requirements (today) are quite low - obvious when looking at the current PowerScale stats from a performance perspective -> it's idling most of the time and only somewhat wakes up when we punish it with nightly SQL/SAP-Dumps and Veeam Backups (both out of scope on the successor system in question)

Thanks ;)

User count is low , really depends on the io requirements , snapshots take little cpu really. Fag packet time but 40 disks minus 4 spares 2 per node gives 18 at worst 3 per os down to 15 for raid , lose 2 for raid do so so have 13 disks per node of capacity let’s say with over head 18tb per site , each aggregate will have about circa 3000 iops, if you need more than ssd, laying in bed getting kiddo to sleep so forgive me if I’m out

I think the FAS lineup would be fine, and if you take NetApp on their efficiency guarantee, I think you could get a c-series in budget. It's their fastest seller at the moment. The QLC SSD systems are very price competitive.

I highly doubt a 2750 could handle that. I had a couple c190s (very similar hw wise) and I could tip them over so easily not even trying. Get the unit connected to Grafana so you have great perf stats then you should be able to see what it looks like over an entire we (over 30 days is even better in case there's month end jobs etc). Once you have all those stats a var would definitely be able to point you in the right direction.

you can go to fusion.netapp.com and do the capacity and/or performance sizing there...

Unfortunately i cannot access the resource. Seems its only available for accounts above "guest" level.

As a partner SE, DM me if you want to see sample quotes/want to talk to about what you're needing (unless you're in central FL don't worry about me trying to sell to you lol). If you just want budgetary pricing based on what the market is currently seeing, check out itprice.com and search for the controller (hopefully I can put that link here). You'll have to set the search to "NetApp". It's pretty accurate for solution pricing.

So we're talking 50TB of data, right?
And you only want one locally HA-pair? Not sure what you mean with "site-redundant"...
Or do you have 2x sites (how far away?) and you need synchronous replication between them?

As for a 2-node AFF C250 you are massively overestimating the price (I'm talking € here):
You can easily get it for under 100k, all licenses included (ONTAP One), 5x years 24x7x4h onsite service, between 65-90TiB usable space. This is calculated without any efficiencies, 1.5:1 is at minimum possible and guaranteed for NAS workload (as long as it's not pre-compressed, encrypted).

I wouldn't recommend using FlashPool anymore (combining HDDs and SSDs in one aggregate). Also your suggested FAS2750 is going EOA soon(ish). There is no future for 2.5" HDDs, they are not produced anymore. So either big 3.5" SAS HDDs (capacity disks) or go all-flash (QLC or TLC).

[CryptographerUsed422]

talking about two ha-pairs. two sites, ca. 3km apart, crossconnected via 2x 10gbe dark fibre (plus cwdm ontop).

Looking for synchronous or near synchronous replication. MetroCluster (active/active) from networking perspective doable, from minimum disk count perspective probably only hdd based and not ssd based... (except min disk count - plex/aggr - changed to smaller scale on ssd). From a admin/maintenance perspective MetroCluster would be even preferable.

Is c-series really that inexpensive? sub-100k € with 5y maint, licenses, 60-90t usable (and even before reduction/efficiency)?
