I keep hearing this ARM server market. I work in a data center with hundreds of servers that I manage (my team and I). We refreshed dozens of VMware hosts this year and met with Dell, HP and Lenovo to go over their offerings.
Not a SINGLE word about ARM servers from any of the vendors.
Partially because most of the movement for ARM servers in contexts where the org is deploying/provisioning 12 systems per week (or perhaps 12/month ) rather than 12 systems per year.
The other major disconnect is that VMWare hasn't had much of a ARM solution until now so if your system is "known" to the Dell/HP/Lenovo sales reps as a "up over their eyeballs deep VMWare" shop , there is little point in pitching you something that your software doesn't run on.
Lenovo does/did have HR330A and HR350A

It is tagged as a hyperscale product. Again not really going to be pitched to a non Hypercaler shop. But also yes Lenovo hasn't picked up on the newest Ampere offerings. ( In part, because hyperscalers are dumping (or perhaps more accurately bypassing ) HP/Dell/Lenovo for bulk server buys. IN part also because folks like Ampere are also looking to cut out middle-man and just sell the whole logic board with server CPU included to users. )
HP and Dell are largely sitting it out. The one megacorp that also was persuing Ampere system sales is/was Huawei . And that ran into trade-war issues. [ HPE has done a couple of semi-custom jobs for folks on contract. ]
As for ARM servers going "no where" ...
"... This year, AWS Graviton-based instances also powered much of Amazon Prime Day 2021 and
supported 12 core retail services during the massive 2-day online shopping event. ... "

Amazon is provision new ARM at a > 1.2x multiple of the new Inte/AMD server deployment across AWS.
But yeah you can't outright buy one of those servers for a private server farm.
Can get to Ampere instances at Oracle
Oracle Cloud is giving away Ampere Altra-based Arm A1 instances in its Always Free Tier with 4 cores and 24GB of memory

There are some Chinese hyperscalers with growing "clusters" of ARM.
An article entitled "where to buy an ARM server" here
www.mininodes.com
With relatively high rates of growth there is a steady stream of "new pods for new services" coming on line that can absorb workloads that need a homogenous failover cluster/pod provisioning. Live migration sometimes doesn't even work between Intel and AMD x86-64 implementations. Let alone nodes with different architectures. So shops that only add incrementally in small spurts around the edges tend to buy what they already have. ( even more so if there is a heavy hand of "if it ain't broke don't fix it" mindset in the shop. The old 'nobody got fired for buying IBM' and "one throat to choke' service contracts mindset. )
midize to large shops with modest (to slow) growth are the last place ARM servers are likely to show up. So no surprise at all they are not there. the x86_64 server status quo shifting over to AMD is slowing down ARM penetration even more. For Dell/HP/Lenovo that's an even easier pitch to risk adverse clients.
At this point AMD has enough money that they can join Intel in waiving financial incentives and resources at Dell/HP/Lenovo's face to back burner any huge attention paid to ARM server chips.
The other problem is that there isn't a dominate , long term player emerged in ARM server market. Marvell dropped out. Qualcomm dropped out ( a while back). Qualcomm buying Nuvia and re-targeting their work to client solutions is pragmatically yet another 'drop out'. Ampere is making rumbling about doing more "made to order" offerings for large players. And Apple doesn't really change Server picture in that in their focus is on laptops and not selling to anyone else. (pragmatically pretty close to being another Amazon AWS in terms of random/commodity off the shelf buys possible. )
The Nvidia acquisition of ARM falling through should help ARM to stay on status quo upgrade path for their server Neoverse designs. If that grows over the next 2-3 years at a steady pace a generic ARM server player probably will emerge from somewhere.
