L2 switches are cheaper, and often cheaper L3 switches canāt route at line-rate, whereas they can switch at line-rate.
If you donāt need detailed packet inspection, acls, etc. then layer 2 is simpler, faster and less expensive to implement.
Cheap L2 switches at the edge. More expensive L3+ capable switches in the core.

Revamping my VLAN schema to account for PVLANs. Looking to have something that is
-
Formulaic
-
Easily readable (base 10 divisions, /24 subnets)
-
Scalable up to an entire /16
-
Virtually impossible to run out of anything (10 primary VLANs per category, 10 community PVLANS per primary)
Thoughts?
I N F R A S T R U C T U R E
Site Number = X
Primary VLANs = P = Y ā (Y+9) # 10 Primaries
Subnets = 10 . X . P . 0 /24 # 1 /24 Subnet per Primary
Isolated PVLANs = (1000+P) # 1 Isolated per Primary
Community PVLANs = (2000 + (P * 10)) ā ((2000 + (P * 10)) + 99) # 10 Community per Primary
DMZ
(VLANs 0,1 unused)

Lets home the pricing is good and tons of capacity options

Agreed. The iron wolf ones are too expensive. 860s work fine on my experience.

Samsung needs to drop their pricing imo too tho
Price has been in free fall for a while, and 5 year warranty included. Been going with them consistently for a while now.
Could be lowers still, but yeah I doubt they get tons of warranty claims

Will probably build a fat twin full of SSDs sometime next year for gluster/iscsi. Hope to afford 1TB SSDs for that.
1TBs have gotten pretty cheap down to half price from like 2 years ago now around what $100 (probably sale price of good ones in the $90s )

Lmao. I was more allured by the PS4 and XBO. All the sales guys are playing Madden and here comes the lonely I.T. guy. Hushed whispers, laughing, pointing, and then an invitation. āOh, come on, it wonāt be so bad, itās a good bonding experienceā they say.

YOU CAN TAKE THE HYPE OUT OF THE GAME BUT YOU CANāT TAKE THE GAME OUT OF THE HYPE, SON.
My employment situation has gotten interesting the last few days. No, I didnāt get fired, Iām not that bad. Most of the feedback I get is that my bustling, bubbly personality is a fresh change of pace in the workplace. PEOPLE WERE IN TEARS WHEN I QUIT MY LAST JOB (tears of joy, amirite?). I have to make a somewhat hasty decision of working with a really badass technology stack but traveling up to 50% of the time or work with a tech stack that Iām not too excited about, but have the potential to influence, change, and innovate during my time there. Also 0 travel, data center is in walking distance from the office. Plus a huge, huge project Iāll have complete ownership of that will completely revolutionize my resume.
Shit. I just wanted to chill out this weekend.

Does anyone have a recommendation for used rack consoles? Preferably with some sort of VGA KVM, but not built-in. Ideally, the display, keyboard and kvm can be replaced separately.
Something like this but with rack hardware included and a kvm solution.
New solutions are all $1000s of dollar which is ridiculous. I just need a VGA screen that can display text readably with a keyboard.

Dell do (or did, at least in 2008-2009 when i got the ones we have) a keyboard/monitor slide-out tray in 1 RU.
This is seperate from the KVM they also do.
e.g.
Its under a grand? 
But heyā¦ itās a niche market - you pay the rate for the limited production run. Or maybe find some second-hand.
edit:
Another optionā¦ shitty second-hand chromebook or whatever in a trayā¦
The HP TFT7600 is a combined display and keyboard unit but it gets my recommendation by default because out of the old KVM consoles Iāve used these are the only ones which are still working. (We donāt connect new servers to KVM anymore, so there has been no need yet to replace KVM equipment as it fails.)
The console has an associated KVM switch which can mount into the same 1U. The switch uses Cat5 or better cable with adapters to connect to VGA+PS/2 on servers. It also supports ācascadingā where a switch can be plugged in to another switch so that all can be viewed through one console. It has worked okay for me with 25ft Cat6 cable and USB to PS/2 adapters.
