    questions about Synology SHR ....

    nope - a lot of their smaller units with limited memory still use ext4, and even on the big units you can still opt for ext4 rather than btrfs if you so wish

    questions about Synology SHR ....

    it uses md to change raid levels however also whilst btrfs supports filesystem level raid, synology doesn't use it ( you can see that examining things from the shell using mdadm - even with btrfs the raid is still handled by md )

    PoE NGFW?

    max draw on the vvx411 is 5w ( https://support.polycom.com/content/dam/polycom-support/products/voice/polycom-uc/other-documents/en/2016/eng-advise-ea48152.pdf ) - so they’re well within the 802.af limit ( 13W ) - it’s just that you need to make sure the total draw for ALL your devices plugged...

    questions about Synology SHR ....

    the ability to grow arrays isn't unique to Synology - it's part of the linux md driver - but the ability to do so whilst mixing drive sizes IS synology only ( in a user friendly form at least, you can do it from the commandline on most linux distros as well, it's not the underlying technology...

    questions about Synology SHR ....

    raid1 is easy to understand/visualise as it just mirrors all data to each drive in a paired manner. Higher raid levels are harder to get your head around - but yes, you have full redundancy ( either 1 drive in shr/raid5 or 2 drives in shr-2/raid6 ), so if a drive fails no data is lost What you...

    questions about Synology SHR ....

    we've got a bit of disk in use at work ( about 0.75pb ) spread across about 10 years worth of servers ( mix of synology rackmounts and old intel storage servers which have been gutted and upgraded with new raid cards etc). Disks range from current gen ( mainly 16tb hc550s and exos ) right back...

    questions about Synology SHR ....

    yes you can SHR all those drives ( 2 * 6tb, 2 * 8tb and 2 * 16tb ) - however the actual capacity yielded will be kind of low ( it’ll create a 6 member raid5 array using 6tb partitions across all drives, then a 4 member raid5 array using 2tb partitions across the 8tb and 16tb drives and finally a...

    PoE NGFW?

    plenty of vendors do 48 port poe switches ( ubiquiti, mikrotik, cambium, engenius and of course cisco), though you still need to watch your total power budget - hopefully your phones are relatively low draw)

    Cisco Firepower 1010

    you seem a bit confused unit-wise - gbe == 1 gigabit/s - if you can iperf a gbe link at 1 gigabyte/s I’d love to see it!

    Cisco Firepower 1010

    other issue with the sg-5100 is it's only got gbe ports - 2gig and 4gig fibre to the home means that's not very future proof the sg-6100 has 2.5gbe and sfp+ yet is no dearer than the 5100, so if you are buying netgate branded hardware the newer model is the obvious choice

    Cisco Firepower 1010

    the sg-5100 only has a quad core atom cpu in - good from a thermal point of view and adequate for a lot of users but not really a high performance solution sg-6100 and sg-7100 are also still atom - you have to go all the way up to the 1537/1541 before you get decent high performance options (...

    Help with a Router Distro?

    they're cheap and they're small. Now dedicating a threadripper - that I'd consider excessive ( unless you've got a 10gig fibre connection upstream ) Obviously you could run esxi or kvm on it and run the firewall virtualised so as to be able to run 'other things' as well, but by the time you've...

    Help with a Router Distro?

    downside of untangle is it's more resource hungry in terms of cpu but an 11th gen nuc the cpu should be ample running it for a 900/40 internet connection - and there's no denying it's got the most 'friendly' UI. The $150/yr is the tier most people really need ( the $50/yr tier lacks threat...

    Help with a Router Distro?

    I think PFsense is more current since it's based on 'mainstrean' freeBSD and netgate actively contribute upstream to the kernel ( specifically for things like this) - so if they support it on their own boxes hopefully the community edition also supports them ( though you could run into the...

    Help with a Router Distro?

    last I looked neither pfsense nor opnsense had support for the i225 2.5gbe NICs due to lack of freeBSD support (intel haven’t released freeBSD drivers for the new chipset) Hopefully freeBSD will eventually get drivers, but right now that will limit you to non-freeBSD based solutions (...
