Just checking – by 1U/2U do you mean you want a rack server and have a rack to put it in?
Planning on buying the whole
so yes(rack+server)
i was thinking of blade style, but feels overcomplicated for a hobbyist like me
compared to rack, plus havnt ever seen blade server in person
so kinda unknown at that part
I actually named my company, Silicon Blade, after Blade technology (and swords – but that’s a different story!)
Blades would be an overkill for a hobby – they are great for being able to quickly replace systems with minimal downtime.
I’ll take a quick look at what rack systems are current as I’m a few years out of date and let you know what I find
I am only seeing online prices for Dell.
Their PowerEdge series looks interesting – either the XR11 (1U) or X12 (2U) – https://www.dell.com/en-us/shop/edge-servers/sf/poweredge-edge-servers?hve=explore+poweredge-edge-servers
The other main option would be HP – https://buy.hpe.com/emea_europe/en/compute/proliant-gen11-servers/c/c001025?q=%3Arelevance%3Afacet_formfactor%3A1U%2BRack%3Afacet_formfactor%3A2U%2BRack&text=&textSearch=&pageSize=10
IBM seem more focused on their AIX Servers
I also found this site – which offers refurbs
https://www.tonitrus.com/en/
I was thinking of going refurbs
From what I see
HP DELL and cisco seems to be a fair bet
What do you suggest the specs I should focus on?
I have more experience with HP & Dell
Considering under 1200$
Key things I would look for:
Storage – LFF (Large Form Factor, i.e. 3.5″) is cheaper than SFF (Small Form Factor, 2.5″) but also LFF tend to be slower than LFF
RAID Controller – especially if you want to use it as a NAS.
Normally you can put more disks in a 2U than a 1U – but then it needs more power and cooling
Number of Memory slots – especially if you want to upgrade the memory later. You don’t want to have to throw away memory just to increase capacity
Don’t worry about dual power supplies – that is more if you wanted fault tolerance. We always used to have dual power supplies coming from two different power banks – but in a domestic setting, you don’t have that option
Makes sense
64 gb ram
3tb hdd
Seems to right for me based on budget and need
Also going through Dell,
What is openmanage?
Is it a bios config?
3Tb seems a bit low to me. My NAS has 8Tb and I’m thinking about upgrading – mainly due to my backups, as my Linux servers have 1 – 2 Tb in each of them, as well as my wife’s work (alouth that is a lot of videos for her art acadamy business)
I was thinking of getting it separately.
Sensible – it’s _much_ cheaper to but separately
Hmmm,
Xeon seems much more common then EYPC
Xeon is the default for most Rack systems, as it is designed for more data centre workloads
Damn
Got a lot from this convo then any of my research did
😂
Server builds are different from normal pc build
they are designed more for high data throughput workloads
Yep.
I think I got what I want
Mainly will be going for the Dell poweredge r730xd
64 gm ram ddr4
5.4tb hdd
2 x Intel Xeon E5-2680
Just one last doubt
Are two cpus HMP, or SMP?
Ther standard IoT answer…. It Depends 😄
SMP (Symmetric Multi-Processing) means all the CPUs are the same. type and speed
HMP (Heterogeneous Multi-Processing) is where the CPUs are different. This is more common in the ARM based world where you may have different processors on the core for different tasks
Do you have any good resources to read about server bring up/comms(from Linux kernel POV) say like CXL, (SMP vs numa), to name a few
I’ll have a look around. Most of what I know comes from just doing the job 🙂
