Hi SlowmoDK, this SAS enclosure is pretty interesting and affordable.the perfect companion for this unit https://www.aliexpress.com/item/1005006064182068.html
model : K35274SAS
3.5" Four Bay Docking Station External Hdd Enclosure RAID Function Disk Array Box Support SAS interface SFF-8088
connect to the sff8087 port on unit
I'm getting one and using as a backup target for my main TrueNAS box
This expand this unit to more general use cases besides just as network router, with the 4 hdd external and the 2 nvme slots internally

I've been using a vga monitor so far, but have one adapter incoming soonish, will report back when it gets hereHas anyone managed to boot into BIOS using a VGA to HDMI active adaptor? Cant seem to get it working
I had tried such a VGA-to-HDMI adapter/converter on other PCs. The video quality from the output to the monitor is not good as what I thought before using it. Only thing is that the view is able to see the screen for the viewer's job, not unable to do so.I've been using a vga monitor so far, but have one adapter incoming soonish, will report back when it gets here
You can look at the benchmarks for the Netgate pfsense appliance that I linked a few pages back. It uses practically identical hardware as the highest tier Qotom model.@SlowmoDK Do u know how well does it handle 10Gbps traffic? How much slower does it become when Zenarmor or IPS is used?
I dunno ... proberly just fine, watch Lawrence systems netgate 8200 review as they are basically same unit besides the 200 mhz bump on newer C3758 R vs C3758 in this.@SlowmoDK Do u know how well does it handle 10Gbps traffic? How much slower does it become when Zenarmor or IPS is used?
Some simple iperf3 tests isn't fully representative of actual internet traffic though. That's why there is such a thing as IMIX tests that are meant to better represent such traffic patterns a bit better. It's why I referenced the Netgate numbers instead, because those are sure to be the best values they can get away with publishing.I dunno ... proberly just fine, watch Lawrence systems netgate 8200 review as they are basically same unit besides the 200 mhz bump on newer C3758 R vs C3758 in this.
My use case is 1Gbit/1Gbit INET and some inter-vlan routing, but i'm only using 4 of the cores for pfsense, the other 4 cores are running TrueNAS CORE
4 cores handles my traffic just fine

My adaptor arrived today, and tested just "fine"/ok, bios working no issuesI had tried such a VGA-to-HDMI adapter/converter on other PCs. The video quality from the output to the monitor is not good as what I thought before using it. Only thing is that the view is able to see the screen for the viewer's job, not unable to do so.
(That means it is not as what I thought as the quality as the regular converter used for from hdmi output to vga monitor input. The video quality is much much lower than that, since its theory and mechanism is completely different.)
I can inter-vlan route at full 10gps all i need or not really since main rig has 25gig direct DAC to main NAS, and the rest of the network is segmented for a reasonSome simple iperf3 tests isn't fully representative of actual internet traffic though.

It's why I referenced the Netgate numbers instead, because those are sure to be the best values they can get away with publishing.
Also, people generally only test in one direction at a time, which is literally half of the performance needed.
I'd say it's borderline (but there aren't many good options with decent prices), and adding an IDS or IPS on top of that is almost certainly a big bottleneck. I'm saying that as someone who is considering buying one to use as a 10 Gbps router. The upcoming fanless device from GoWin is the other one I'm currently looking at.
Update:Hi SlowmoDK, this SAS enclosure is pretty interesting and affordable.
I searched the model name on alibaba.com, its manufacturer has below SAS models, but all are wholesale only, due to alibaba.com's rule:
RAID HDD Cabinet, RAID HDD Cabinet direct from Shenzhen KSY Co., Ltd. in CN
The official site's 2 categories on this SAS enclosure series:
SAS HDD Enclosure and docking station-Kintec
深圳市凯祥源科技有限公司专业生产移动硬盘盒,硬盘座,易驱线,maiwo麦沃,移动电源,充电宝www.kintec.cn
I see.I can inter-vlan route at full 10gps all i need or not really since main rig has 25gig direct DAC to main NAS, and the rest of the network is segmented for a reason
I know you posted the netgate numbers earlier in tread, but video also has same slide as part of review
What cpu are in those GoWins ?
You can look at Netgate's official pfsense and TNSR benchmark numbers for the Netgate 8200.Would the CPU be able to route/NAT/basic stateful forewall at 10 gig? I have 10 gig fiber at home but my current gear can only handle 1Gbps.
Even on plain OPNSense (I’d be running it virtualized in Proxmox with PCI pass through for the 10 gig NICs)? Or does it need to use TNSR to reach those speeds?
Yes I’m getting the advertised speeds, no issues really so far other than the x553 wasn’t compatible with an active dac I had. I just picked up a 10g RJ45 port which works perfectly.
the overall case does get very hot, definitely don’t want to put it anywhere in a closed environment. I have it in my garage, which is quite warm , load gets to around 60c . No idea how hot the heat sink case is but you can’t touch it for longer than 2-4 seconds without wanting to remove your hand. After around 1 min power off it’s cool enough to handle for longer. Also worth mentioning, I replaced the thermal paste underneath with a higher quality, I didn’t turn it on with original paste as I wanted to get the best performance. Also worth noting that the VRM chips are also cooled via thermal tape.
For whoever is interested these are the jumper locations for auto power. Just connect a jumper to the pins shown in red. The headers are named panel 1
Welcome to the forum!- You see those first party switches/router that have combo ports, either SFP(+) either RJ-45 on the same controller ? Think it's possible to do the same (through software I'm guessing, here OPNsense) with the interfaces available ?
The 10G SFP+ ports are Intel X553 NICs integrated in the C3758R SoC, yes. Intel often vendor locks their NICs to only work with Intel programmed SFP+ modules (with the exception of passive DACs), although this can often be unlocked through flipping bits in their EEPROM or through driver flags. I don't know whether the X553 NICs in this particular device are unlocked or not, but you can get cheap fiber transceivers vendor coded to appear like Intel branded transceivers just in case. GBICs are no longer a thing as far as I'm aware. What you are looking for are either passive DAC cables (for short runs), fiber modules/transceivers (long or short runs) or 10GBase-T modules/transceivers (avoid unless you have to). In terms of fiber there are multi-mode and single-mode, and a few generations of each.- I've read in this here thread "NIC is X553", after asking around, I've been told this is an Intel NIC, I'm guessing the ones integrated to the C3758R or so says Intel's CPU spec sheet, do I need to look for Intel compatible GBICs then ? (First time dealing with fiber hardware, still learning what to look out for, advice welcome)
I was thinking about the ports 9 and 10 here, it looked interesting so I was wondering if it was possible to reproduce that, not that I need it or anything, mostly out of curiosity but after some thoughts put in it, it's probably more effort than it is worth...It's not clear to me what you are asking for. What do you want to do? Bridge some or all of the ports in software to make them all a part of the same network (i.e. act as if they were connected to an internal switch)? Since they are all individually connected to the CPU, that would be very inefficient and you would be better off with a switch that will do all that in hardware.
Oh, what is a GBIC, what do we use today and what's the difference between the two of those ?The 10G SFP+ ports are Intel X553 NICs integrated in the C3758R SoC, yes.

All the ports on this unit can be used at the same time as far as I'm aware, they didn't cheap out and make it "one or the other".I was thinking about the ports 9 and 10 here, it looked interesting so I was wondering if it was possible to reproduce that, not that I need it or anything, mostly out of curiosity but after some thoughts put in it, it's probably more effort than it is worth...
I've never personally dealt with GBICs so I can't tell you anything else than what you can find yourself. What you are looking for are different kind of SFP+ modules/transceivers.Oh, what is a GBIC, what do we use today and what's the difference between the two of those ?
I wanted to get a couple of 10GBase-T transceivers (no idea if those are good, compatibility lists includes Intel, hopefully they aren't 10G locked and can retrograde to lower speeds... They're the only one at that price point, anything "brand name" or from specialized websites like fs.com is stupid expensive and that's before VATs and shipping ) exclusively for testing/tinkering purposes (as I don't have yet anything that actually uses/benefits from fiber, that'll probably be my next purchase, we'll see) and also it doesn't hurt to have a back up on hand at the ready so I can just hook a laptop in an SFP+ port for troubleshooting and/or accessing the management interface of the router (if I end up locking it out of the built in RJ-45 interfaces)
Talking about the DAC cables, yeah, when I get there, it'll most likely be passive very short ones, my "IT cabinet" isn't Versailles sized and I don't drag links across the house so that'll be more than good enough anyways.
I appreciate the welcome, sorry for about the slew of questions, I'm just really excited about all the new stuff I'll be able to do with my new box !
