  1. @Embeh You can basically go for any LSI/3wave/Avage/Broadcom SATA/SAS controller or raid controller with IT mode ora IT Mode compatible. There many card like IBM Megaraid, DELL Perc, Supermicro or other but like i mention first check if card have LSI/Broadcom chip. Here you can find all old chip and card that support HBA mode that can be bayed on ebay and can be crossflash to support newest LSI firmware https://forums.servethehome.com/index.php?threads/lsi-raid-controller-and-hba-complete-listing-plus-oem-models.599/ But i don't like this episode: - They mentioned costs but go unRIDE. - They mentioned stability and still go unRIDE - They mentioned VM and still go for unRIDE Why you didn't finish episode on FreenNAS from last year? and in this episode didn't show FreeNAS (even when you mention it). I think It's better then unRIDE and its FREE. O and i forget mention that your suggestion to configure zvol and vdev is totally wrong and misleading. At last FreeNAS creator cover for this: https://www.ixsystems.com/blog/zfs-pool-performance-1/ https://www.ixsystems.com/blog/zfs-pool-performance-2/ Yes i know what im saying. I build many NAS home and for corp (trying many software and ended using FreeNAS for all of them). Next is that no matter with platform you use (Linux of *BSD), because of limited participation form AMD in creating drivers for Linux/BSD performance suck. PS: for NAS you can use old hardware like Xeon X series with support ECC and it cheep like DELL T620 with 12 x 3,5 hotplug + Perc H310
  2. Nice but what i point of doing this? First routing between VLAN's using L3 is slower then o L2. Second we still will have issue witch VLAN and trunk between switches of two different producers (i presume they have more then one switches in LAN). Third moving DHCP to switch you may loos some flexibility (sone switch have missing some DHCP feature) Forth when you change mode to L3 then you loose some switching feature and make it work even harder. The configuration you just proposed have more sense when you have building and rent office to different company but not when you want simple and fast office LAN. .
  3. For first in most of the country getting faster ISP connection then 100mbps is so expensive, and they don't bother to use gigabyte Ethernet port, and is lot cheeper. Other thing you cot that wrong. Even if your WiFi card show that you get 1167Mbps, you will never pass 150Mbps its protocol limitation and how its work, maybe on 802.11ax and WPA3 this will change for consumer devices. Yes you have right about vyOS (Ubiquity uses for of original vayetta) but you must remember that vyOS ots stricte optimalised for switching and routing only. there is almost non other services like on PFSense, and limitation on FreeBSD (as most know every record that science show was break on NetBSD :D)
  4. The installed or try to install 2 x 40GbX QSFP+ ports https://youtu.be/aGq8uJSco1o?t=675.
  5. You didn't listen. The have consultant who helped them (the didn't hire one ever) and he retired form consulting so i presume he got offer to work on some small/medium/large company.
  6. Not only that. Without proper knowledge about networking, people trying to create BIG and fast LAN. like this: - i you have 1GbX network then core would be one level faster, so , when you use 10GbX you should have core on 40GbX ... but Linus i trying to run server on 40GbX so then not only he should look for new switches, one will be fully 10GbX with 100GbX Uplink and second switch with 40GbX ports and 100GbX uplink. I don't think that DELL he have cane make what they want (i know maybe 100GbX is to much but the looking for very fast connection to server when everyone using 10GbX).
  7. You are wrong, there is dedicated hardware, NetGare offering one.
  8. I have tested this like Lawrence System did and have that same result (but on hardware not VM). When you have big traffic and at that same time you want to filter it, then you need raw power and i mean RAW. Especially on 10GbX. About my point on 40GbX over 10GbX, i got my first problem about 4 yeas ago when client got 1Gbps symmetric. We couldn't get past 700Mbps. When we ask our ISP the said that they provided us fully 1,2Gbps. We got perfect 1Gbps after some twerks on router (i mostly use Mikrotik, Ubiquity, CISCO or PFSense because - and that may be fun CISCO - its more affordable) like changing deviate to one with 10GbX interface. About the source, just read about OSI/ISO MODEL, Ethernet and TCP/UDP protocol design, its explain almost everything in link i provide to tune FreeBSD are little explanation too. Other thing is that you must remember that maybe expect NetBSD and OpenBSD with is mainly developed for network and server purpose and optimalization (and OBSD with security by default), FreeBDS is mainly for general purpose. Configuring VLAN on Mikrotik is simple (2h with doc) but making it work and compatible with other device that take weeks I think problem is in terminology and implementation. To this day i couldn't make work native VLAN on Mikrotik with CISCO, and TRUNK between DELL,HP and CISCO properly but on CISCO to CISCO its working like charm. I don't think they need 9k series but based on what they need NEXUS series and minimum 3000 or above. Small enterprise don't need more then 1Gbps these days, most don't need more then 200mbps or even less.
  9. Looking on this video make me cry an goosebumps. Like @mynameisjuan say, you are done this horrible this time and wrong - almost horror for network admin and engineer. Horror movie I must point few things: As i know, you don't need do screw server rack door, you can remove them (read manual), Star using server KVM like this site - cheep, less space and more comfortable to use Stop using different network devices, and believe me when i say if you need then use CISCO for networking (like NEXUS 3000 for 10GbX - YES you can buy refurbished too, for less then 1200$). Reason is simple - VLAN's and other network issue will disapere. About VLAN, on DELL not working that same as on CISCO or other devices compatible with IEEE 802.1q, that same issue you will find in HP, Mikrotik, D-Link and few other especially when using TRUNK. When you cleaning server you should remove most of the parts like, PCIe card, fans, disk and power supply. As IT technician you should know this ? Ok. Some other advice: First if you upgraded to PFSense and custom hardware then i presume you also considered to run some sort of IDS or IPS in network. I don't think that on this configuration will work smoothly on only 32GB RAM (you should upgrade to 64 if not 128GB especially snort - only IDS you should run on PFSense - will take almost all resource it that configuration). I advice to make some changes in sysctl for kernel like its pointed on this site, you not be disappointed in result (i do this on any FreeBSD/OpenBSD server i administrate). Of corse better choice will be Fortinet (FortiGate) for the price but its your choice. Other thing is if you want to get full 10GbX on WAN and push this to LAN then you should consider replace 10GbX port to 40GbX - only then you will get full 10GbX on WAN. As for CARP ... you can do this using BGP, so don't need to have two identical device (i presume you know that if you want take full advantage of fail over the you shoul have two identical devices even if you use CARP - CARP is *BSD [created by OpenBSD] alternative to CISCO HSRP and IETF VRRP and it working almost identical but using encryption). Configuration on UBIQUITY EdgeRouter Pro is not compatible with PFSense so you need someone who understand both to migrate configuration Is i see your notwork didn't work, and because i we don't know if PC got IP (and right one) then i will try point few things to check: - did you configure NAT? dynamic or static? - did you configure VLAN on TRUNK properly? TRUNK on LAN interface in router - not WAN? - did you configure routing like entering proper GW for WAN? - did you configure DHCP properly for each VLAN? - did you configure TRUNK on proper port in DELL and VLAN on ports when PC is connected? - remember PC port should not be TRUNK This is all i can help with knowledge i get form video As for servers ...: - in modern RAID card, the order of disk don't matter. When you create RAID disk all information about RAID ID and RAID type is stored on DISK - that's why when you move disk to other server with that same card model or that same manufacturer RAID card detect RAID configuration and import it. - you should confider to change consumer grade SSD like Kingston to something more reliable like SAMSUNG Enterprise SSD, INTEL DC SSD, Micron or other enterprise and server grade one. If you need any hep you can msg me
