Slowness.
Yes that one of the main issues on our deployments.
Teams using 700 to 900mb of RAM. Why so much ?.

I may or may not work for Merica's largest bank. And we have two PDP's in the main DC in the UK. Both of 1978 vintage.
We also have another 4 in the spares room for parts should we need them but amazingly they just keep on going.
Apparently they are still used for some function of payment processing, because and i quote "They software guys cannot figure out how to do it in a modern database".
And the chaps that supported the PDP have long since died. So its up to me and the rest of the HW DC team to swap out boards when required.
Part of the process on our incident tickets is for the service desk guy to log into the iLo / iDRAC etc and turn the UID LED on for the DC floor engineer. (Me).
Then when we walk the hall we can find the server. The server / ESX physical host name is also a reference to the Isle and rack number so you literally cannot get it wrong.
I work in UK banking, and yes almost all cash machines in the UK that are major bank operated are still generally Windows XP embedded.
They have no internet connection, and they are not generally permanently pinned up. They all use ISDN2e to call up huge arrays of modems generally in Banking DC's.
They only real way to crack them is physically via a USB attack or such like. So you need to gain access to the unit within the locked cage itself.
Also lots of people mentioning NHS computers. Ive also done alot of NHS work in the past, and again "Generally" the machines that are still running XP are on nhs.net which is an internal mpls network which does not have any external access. Only the internal nhs.net Intranet.
There is also a part of the MoD in the UK that still has a Honeywell DPS 6 mainframe in service. And for very good reason.
It has no connections to the outside world, just internal 10base-T coax. And apparently there is no one left alive in the world that could even de-compile the databases.
They even had 2 spares in storage that were shipped over from the US.
Same with newer Mercedes cars from approx 2014 onwards.
If the last owner does not login online and remove the car from their Mercedes Me account, then they can continue to remotely monitor the car. Lock / Unlock doors, etc.
Non-Mercedes dealers have no control over this. Where as main dealers can terminate the accounts during re-sale.
The trains, along with some buses & coaches all use ProRoute H820 routers.
Ive personally replaced a few in trains. They generally have one large OMNI 12dbi antenna, and the routers feed Aerohive wifi AP's.
They do struggle though when you have 150+ clients attached all reading faceache and mail online.
Ahh 10base2.
I remember working on a contract with a Digital DEC engineer in the early 90's, who showed me an amazing trick with 10base2.
He inserted a sewing needle into a 10base2 cable, pressed right into the cable.
Then using an old 286 laptop in the next room he connected some RF device in a rather home made looking black box to the parallel port. Apparently it was some kit they were using on this UK Government contract at the time in 1991.
He was able to listen into the network traffic on the 10base2 network, wirelessly !.
The first wireless network ?
We got rid of Softcat a few months back after using them for 6 or so years.
Absolutely fed up with their late and slow deliveries. Not even competitively priced either.
RE the person above who said good stock levels. They dont hold any stock at all. Not even so much as a pencil sharpener.
They are a reseller, and just get items drop shipped to you from the main wholesaler. Generally WestCoast in Theale Berks.
Now with BT for Business. Formally DABS. They have the largest stockholding in the UK. Cheaper too.
This has been a total PITA for us today. Hardly any mailflow at all for 1,400 staff.
We all told the IT director 4yrs ago it would be a bad idea to get rid of our Exchange cluster. Which we owned with perpetual licenses...
But oh no, got to go with this new fangled Cloud hosting, because its what all the big boys are doing..
Ughhhhh...
Just does not sound right.
I work in a Bank DC in the UK, and we have 5 mirrored DC's throughout the country.
Ours has 3 different incoming power supplies from different Counties.
Plus out the back, we have 8 massive V12 Diesel Generators that would power a small town.
Now i would imagine that BA would at least have something on the same scale, if not bigger.
So why the outage ?......
We do Power tests every month. An incoming power feed is killed, to check redundancy.
We also shut off 1 of the 2 power rails going into each cab, again to test redundancy.
Perhaps BA are running their backbone on some beefed up PC in someones bedroom ?.
I always used to put on a really old mans voice and say we didnt have a computer. Dont know how to use those modern fangled things !.
Now we dont get any fake MS calls anymore, so guess we were taken off the list. Yay !.
Bit like the Conservatory companies that used to endlessly phone up. I started saying i was in a 5th floor flat, what do i want with a Conservatory ?. Now we dont get them calling anymore either. Good times...
Actually if you are a UK PLC, current data retention laws state that your data and in particular Financial data must reside in the UK.
So UK PLC's cannot use the MS Cloud in the US or Canada.
I recently helped clear out the BoA DC in Canada Sq London. There was talk that MS were going to take that one over.
The largest bank in America, within its largest DC has a
Digital Equipment Company VAX 11/780. I believe we put it in around 1990. So that makes it 27yrs old.
We also have 1 full spare unit in the lab, just for bits. But actually we have not needed to touch it in the last 8yrs.
I know of a Honeywell DPS6 server that was installed in 1985 if I remember correctly.
Which is still in "Production" use today.
We even purchased 2 junk units from the mericans to use as spare parts.
Unfortunately the DB running on it is so bespoke, no one can convert it to a modern back end system.
So, that's 31 years.
Back in my contracting days i may or may not have worked at the NATs center during its construction at Swanwick.
Many memories on night shift overtime, plugging a PS2 into the massive 200" screens and us playing Crash Bandicoot. Freaking awesome !.
The nights works had been completed but we always had many hours to waste on the shift.
I replace about 5 to 6 Dell 900GB drives every night.
But we do have 7,500 R720's !.
They are a pain in the rear, as dell don't ship the Carrier anymore, just the bare drive. So you have to swap the drive into the old carrier. Dropping the screws through the vented floor in the process... Ughhhh
At home we have a SmartUPS 1500 unit with no internal battery. Instead, re-wired to a cable that goes outside to a small plastic box that has a Car battery.
We use the UPS to cover the TV, virginmedia kit, and all the internet comms + hifi. Oh, and a standing lamp with an energy bulb.
We have lots of power cuts, so having a UPS was a must. Running on a car battery the TV will run for almost 3hrs. And a car battery is ALOT cheaper than a APC RBC7 battery.
As I mentioned last week.
A certain very large high street bank, has a Digital Equipment VAX unit from 1976, still in continuous operation in its "Production" network.
We even have 3 others in the parts room to strip for parts. But to be honest it never fails. Just keeps on working. Doesn't half kick out some heat though, like standing in front of a hair dryer.
Also got about 10 Compaq ML370 G1's running NT4 Server in the Production network. They would be from around 2001. Those old 9GB SCSI disks just keep on spinning..
