| That's super interesting, enjoyed reading it.
|
| I am pondering of getting a good future-proof server Soon(tm) but
| I have my doubts about how cheap (or awfully expensive) this is
| going to be so I will likely settle for a refurbished Xeon E5
| workstation (since I'd like less noise and the ability to cram it
| full of HDDs/SSDs).
|
| I wonder if the coming of this new-age SSDs will herald a price
| drop in the classic 2.5" SSDs? I don't believe so because they
| will be viable for a long time in the future still but I am
| curious to hear other people's perspective?
|
| What do you guys and girls think?
| jlawer wrote:
| Markets like web hosting will eat any discounted 2.5"
| enterprise SSDs. Don't even mention stuff like chia.
|
| There is such a large market for 2.5" storage that I don't
| think we are going to have a large discounted sell off, unlike
| say DDR4 ECC DIMMs
| ksec wrote:
| Cant wait for all of those to arrive. We have a sort of
| stagnation in the past 4-5 years and only only just started
| moving again. Network, Storage and Compute.
|
| For consumer I really hope we will get 5GBASE-T. Even if it is
| just one port on the Router would be better than 1Gbps port.
| sokoloff wrote:
| It seems to me like 10Gbps is already "cheap enough" to use
| where it's appropriate. DAC (copper) is crazy cheap and
| fiber/UTP are also pretty cheap. 30m (~100 ft) OM3 fiber is $25
| retail; SFP+ 10G fiber modules are $20.
| vbezhenar wrote:
| How do you connect fiber? I thought you need very expensive
| soldering tool which stopped me from looking at fiber for
| home network.
| sokoloff wrote:
| Buy pre-terminated fiber patch "cables". They have ends on
| them (LC is the common one) and plug in like pre-terminated
| Ethernet cables.
|
| Terminating bulk fiber does require special tooling, but is
| generally not needed for a home installation.
| tremon wrote:
| The modules and NICs are in the affordable range for network
| enthusiasts, yes. But I haven't been able to find 10GBase-T
| switches at consumer prices yet. Do you have some
| pointers/recommendations?
| pdimitar wrote:
| Mikrotik have 2-3 great 10GbE switches in the $250-$400
| range, if memory serves.
| sokoloff wrote:
| Have a look at the Microtik CRS305-1G-4S+IN. 4 10Gbps SFP+
| ports with an MSRP of $150 and a street price just under
| that.
|
| For direct connections (NAS to VM host, for example), you
| can also forgo a switch and wire them directly on a private
| point-to-point network.
| dnautics wrote:
| A minimal used 10Gbps switch from a cloud-provider grade mfg
| (arista, cisco, juniper) will run you ~5k, which is pretty
| expensive. But they are really loud and most people shouldn't
| put them in their homes.
|
| Microtik is probably good enough for most home serving usage
| (honestly it would probably be good enough for a small cloud
| too), and is much cheaper, and way quieter.
| pdimitar wrote:
| I am still pondering buying a 10GbE Mikrotik switch. There
| are 1 or 2 models without a fan -- or such that ServeTheHome
| says don't make a lot of noise but I'd still be super
| hesistant to use those -- and I haven't pulled the trigger
| yet.
|
| Do you have any experience with them? Any pros and cons?
| dnautics wrote:
| I've only ever configured a mikrotik _router_ in the
| datacenter and it was a good experience. We did not wind up
| deploying it though so I can 't speak to it's reliability,
| uptime, or anything.
|
| PS hi pdimitar ;)

| Fiber is easy if you buy fiber patch cables, and just coil up

| surprised if there's no real progress in copper networking in
| the next few years.
| sleepydog wrote:
| I've been considering getting fiber to connect two switches
| on opposite ends of my apartment. The distance is short
| enough that I could use a slim Ethernet cable, but even the
| slim ones are pretty noticeable. Fiber cables can be
| incredibly thin.
|
| I did research, and the problem I found was that there is
| very little availability for fiber cables of alternative
| colors. Most of the cables I found that were the right type
| and thickness I wanted, I could only find in bright yellow
| that would stick out.
|
| There are a few products like invisilight that are incredibly
| thin and almost clear which would be ideal. However, they're
| only sold in bulk to businesses so I could only find some on
| ebay. It felt too adventurous for me to pull the trigger.
|
| Currently 5Ghz wifi is sufficient, but its bad enough that I
| refrain from doing anything that consumes a lot of bandwidth,
| like torrenting.

| sleepydog wrote:
| I do not have coax. Power line ethernet is an option, but
| I've heard mixed stories about latency/loss.
| lxchase wrote:
| I believe some prefer Copper despite length limitations or
| interference, because it's less power and heat compared to
| fiber and the receiver to translate the light.
| wmf wrote:
| 2.5G/5G/10GBaseT is probably higher-power than fiber.
| candiddevmike wrote:
| Really looking forward to reasonably priced ARM servers with
| modular/beefy RAM. I don't get the trend of everyone running RPi
| clusters with the tiny amount of RAM they have, how do you use
| that for anything serious?
| dijit wrote:
| Something I didn't quite realise with the rise of "The Cloud";

|
| That notion only just hit me with the title, and I'm a little sad
| about it to be honest.

| Do they?
|
| I was working for a big US tech company in the UK. They
| regularly use to give servers and computers for
| decommissioning/dismantling. Once I asked if I could get
| those servers and computers to give it to schools and
| students who could not afford to buy one. I was told that it
| is not legal to give company computer away. There are
| restrictions on giving company computers in the open market,
| even if it is free.

| Afaik, in uk, schools and the likes need to get
