Details and experience from S5800/S5850/S5900 switches?

So somewhat long post but there are a few question at the hottom (if you survive that long? ;-)

Im currently looking for replacement of HPE FlexFabric 5820X 24XG SFP+ Switch (JC102B) that is something that can do IPv4/IPv6, MLAG, a few ACL, if needed dynamic routing (but not a full internet table) such as BGP and have at least 12xSFP+ (10G, preferly 1G/10G slots). Would also be nice if there is a capable builtin DHCP and DHCP6 server too (like be able to lease based on option82).

HPE suggests HPE FlexFabric 5940 48SFP+ 6QSFP+ Switch (JH395A) as replacement but that has a riddiculous pricetag, about $18875/each around here + VAT.

So I took a quick glance at what FS.com has to offer and found these models:

• S5800-8TF12S 12-Port 10Gb SFP+ L2/L3 Switch with 8 Gigabit RJ45/SFP Combo Ports for Hyper-Converged Infrastructure #69404, $1900/each + VAT

https://www.fs.com/products/69404.html

• S5850-32S2Q 32-Port 10Gb SFP+ L2/L3 Data Centre Leaf Switch with 2 40G QSFP+ Uplinks #29122, $3000/each + VAT

https://www.fs.com/products/29122.html

• S5900-24S4T2Q 24-Port 10Gb SFP+ L2/L3 Data Centre TOR Switch with 4 Gigabit RJ45 and 2 40Gb QSFP+ Uplinks #73467, $2500/each + VAT

https://www.fs.com/products/73467.html

So a few questions:

1)

Anyone in here with some info regarding what are the main differences between the S5800, S5850 and S5900 series of switches which FS.com provides (other than what the datasheet for each model provides)?

Do they for example have equal feature set when it comes to IPv6 and what else - and what about ACL (well ACE's) capabilities etc?

2)

Is it sane to assume that S5900 is the newest out of these?

Like that they were released S5800 -> S5850 -> S5900 and not something like S5800 -> S5900 -> S5850?

Looking through the datasheets the one for S5900 have a different design then the other two.

By looking on when latest firmware were released (doesnt necessary mean anything) the S5800 was last updated in may 2018, S5850 dates in august 2018 and S5900 was last updated in march 2019.

3)

Also looking through the productpages its namedropped that S5900 uses Broadcom BCM56846 (Trident+) but not a word of which CPU is used for the mgmtplane.

While the other two is namedropped that Freescale PowerPC P1010 is being used as mgmtplane CPU but not a word of whats being used as switch chip.

Anyone who can fill in the blanks?

4)

Looking through particullary the S5900 manual I get strong Comware (aka HPE A-serie) vibes from it.

Comware comes from H3C which was a joint venture of Huawei and 3COM then HPE bought 3COM and H3C came along.

Later on HPE sold H3C along with the Comware stuff to some chinese university or such: https://www.reuters.com/article/us-hp-m-a-tsinghuaunigroup/hp-sells-2-3-billion-china-unit-stake-to-forge-partnership-with-tsinghua-unigroup-idUSKBN0O703V20150522 - this was in spring 2015, now 4 years later it seems like HPE ditched Comware all together from documentation and what else (unless someone in here got some other info to provide?) and is phasing out the Comware productline in favour of ArubaOS (previously known as ProVision aka HP E-series who then merged with well Aruba and became ArubaOS).

Anyone who might know more of this backstory? Has FS.com somehow teamed up with the leftovers of H3C or are they in a joint venture with Huawei (due to very similarity of the commands in their firmware)?

5)

And finally what is your (first hand) experience from these models, how have FS.com worked when you needed to file a bug and how fast was it resolved etc?
