I worked at a datacenter as a technician in high school in the early 2010's, and used to love exploring all the various machines people would bring in to colocate, as well as "junked" / "e-waste" machines we had in the back. We were primarily a supermicro shop but I always thought the PowerEdge servers were the cleanest looking, especially the giant blade chassis. That being said, the supermicros were built like tanks, despite being so barebones/no frills. We had some Supermicro Pentium-4 machines _still_ running at that time (customers who refused to upgrade) and they must have had near 100k of runtime hours at that point. Would love to see an early Blade chassis on the channel at some point, though you'll definitely need a hand lifting it they can easily weigh 200+ lbs loaded.

@37:30 a reminder of my AS/400, RPG and CL programming days.. fun fact, being of the younger generation in 1996, Windows kids, I wasn't too keen on mono color screens, but we got to appreciate how earlier research had shown that green on black was actually less tiring on the eye than multi coloured displays/UI. Something you come to realise now in your 40s.

[@Karatechopsin]

For the Hardware Calendar error Cisco devices have a Hardware clock and a software clock. They are separate and can be manually configured separately. Try this. You set the clock in enable mode not global config Router#calendar set 07:57:23 23 march 2024 (current time, day, month, year) This will set the hardware calendar clock to whatever you set it too Router#show calendar This output will show the current time, do this to verify it worked Then do the following Router#clock read-calendar This will sync the clock to the calendars time Router#show clock and Router#show calendar should be the same and that error should go away.

[@clabretro]

That fixed it! I had tried setting the calendar but didn't actually sync the clock to the calendar time. Thanks!

I love these videos. Especially the Cisco stuff. I had my CCNA from 2005-2008 and worked at a company that refurbished and sold old Cisco gear. 2500 routers, 2600xm, pix firewalls, 6500 catalyst switches etc. brings back memories. I’m studying for my CCNA again and I’m buying Cisco gear up lol

[@dkpriest]

the LICCODE procedure message got me thinking, i wonder if your machine is set for Capacity Use on Demand ("CUoD") ? That's the pay-per-use thing that IBM had that it would lease the hardware (or sell for very very cheap), and the HMC would keep track of your utilisation and call home with that info, and you'd be billed for it. I never really serviced that, only really touched it when we once got a machine setup like that due to some mess up in our order, but the symptom would be pretty much the same, it refused to power on properly (IIRC, because the HMC has to be setup for it specifically) Can you check the licence entitlements on that machine, and see what's in it? Also, it'd be amazing to get this one running, because it (looks like it) does have VIOS support! So you should be able to do full virtualisation on it, down to virtual block devices! (think vmfs-equivalent)

[@icanrunat3200mhz]

That old school JDE interface screenshot brought back a core memory. A family member managed iSeries gear when I was younger and the company was kind enough to let me hang out in a corner and tinker with the derelict tech from time to time.

[@swrzesinski]

SD-RAM, DDR1 and newer, are actually in two groups: unbuffered and buffered. Unbuffered RAM (UDIMM) has no buffer chips. It is compatible with consumer and entry server market, could be non ECC and ECC. Buffered memory usually needs high end server platform, all buffered memory types are ECC. Buffered memory, could be registered RDIMM, from Ddr2 and up also fully buffered FBDIMM or load reduced LRDIMM. They have additional register / buffer chips. There was some exceptions with compatibility, Registered sdram was compatible with desktop 440bx chipsets, registered DDR1 with 939 socket etc.

[@kaitlyn__L]

Mm, buffer chips… 🤤

[@izaboomaster]

I am watching you talk about 720xs while actively decommissioning 720xs in the network I work in.

[@izaboomaster]

Also the chassis fans are not field serviceable it's a real pain in the NOC when they die as it's a whole unrack and re rack different chassis. Also the PAEs in the front are not hot swappable from experience non zero chance of shorting and the NPE rebooting or just completely bricking. Neither things you want in a production network lol.

[@UpLateGeek]

Speaking of fiber [sic] channel, we just retired the last FC system at work. It was part of a huge SAN that was also connected to a tape backup library, and was replaced by a much smaller (physically) ISCSI SAN. The new one is all flash, insanely fast, and has way more capacity than the old FC SAN. They were also replacing the entire workflow that ran on the old SAN, which meant restoring hundreds of old backup tapes and transferring the archives into the new system, which archives everything to S3. They've only got a 1Gbps direct connect to the storage gateway in their AWS VPC, but it's still way quicker to restore data from S3 than tape because they don't have to request the tape from the storage company and wait for it to be delivered the next day.

My first job after I finished University was at an ISP help desk. Right around the time of ADSL but still a lot of dialup around too. (2003-2004) I got to receive a 7206VXR from our HQ in another state and an ATM card to install j to it before handing off to another team to rack and commission. Good memories 😊

[@clabretro]

I've got a couple ATM port adapters, I'll eventually try that out too!

[@Jerrec]

This is no "special" connector. It is the standard connector for so called FC Drives that where in use from IBM, HP and EMC. EMC used it until the CLARiiON CX4 Series. Then they transitioned to SAS. They even had SAS-FC interposer, so they can use SAS HDD's as replacement for the aging FC HDD's, because the CX4 life was quite extended. The last ones I saw in the 2010's. I installed and designed consumer solutions with those mentioned CLARiiONS for 15 years.

[@abb1793]

I was surprised when I got to that part of the video, I was expecting the SCA-2 FC-AL connector, which is like a half-size parallel SCSI SCA-80 connector. But nope. Haven't seen that one before.

About the HMC RAM - That machine has an unused flot for a second CPU and 8 slots for RAM. So half of those slots are connected to the second CPU, and won't work without it.

oh geez you're totally right! I didn't even think about that!

Nope, that machine predates the use of integrated memory controllers on Intel systems, so all the RAM slots attach to the northbridge.

If you‘re going down the rabbit hole of FC connectivity, mind compatibility issues. I remember FC in those times you‘re sourcing your hardware from was extremely finicky as far as compatibility was concerned. Sometimes you had to flash one specific version on your HBAs to ensure connectivity between HBAs, GBICs, Switch Ports and JBODs. Ah, the fun we used to have… 🤣

[@shrdinc]

i was upset but snow was a viable excuse...this time. Time for a redundant data center!

[@UpLateGeek]

Yeah, Cisco did like hiding those little batteries inside their older gear. I got caught out by an IUPS failure (Interruptible Uninterruptible Power Supply - all UPSes are interruptible!) with a Catalyst 6500, which also took out one of the power supplies. It didn't come back after the support provider replaced the power supply, turned out one of the modules also had a flat battery. Thankfully it was replaceable, because the replacement module that the tech brought was actually faulty, so swapping out the battery brought our old module back. It did require the usual magical CLI incantation to get it booting properly, which the engineer back at the support provider's office knew. They definitely earned their support fees that month, because there's no way I would've been able to get us back up and running that quickly since I've never seen that kind of failure before.

[@callmefoxie2950]

I have got here something like 5 or 6 boxes of the IBM FC SANs. Tore all but one apart already, gonna use the chassis for *something else, not sure what yet*. The rest has been scrapped fore recycling because who needs FC/SATA limited to 2TB nowadays. Might keep one "just in case of retro" but 3U is just too much to keep around with several boxes of random server hardware.

Power tower of Cisco gear is growing

[@d3yuen]

Bro ... Re: your IBM Storage ...I see someone else offered you a DS3000, but some thoughts: *Wild guess* --but that looks like a EXP710 expansion tray; it's not a self-contained complete storage array ... you're going to need (minimum) the following to make it work: - Controller -- that generation is either DS4000 or DS6000 (?); you'll need to cross check (IBM Redbooks?) to see if DS3000 can interop with exp710 expansion trays - Storage Fabric FC (fiber channel) switch (either brocade or Cisco MDS) - fc host adapters (HBA) - fc cables (some spares won't hurt) You might feel the urge to get multiport HBA and that's fine. If you do, you'll also need the corresponding multipath drivers for the respective host OS. IBM used to require an active maintenance/support contract to get access to the drivers and respective microcode ... and with IBM gear, it's like 80% reading docs and prep and 20% keyboard to make it all (eventually) "work".

[@d3yuen]

If, when you start out (assuming you're following the IBM documented guidance) and the performance sucks really bad ... (1) enterprise storage is a mental shift ... its all about scaling for a very specific performance requirement/target (i.e. latency or IOPS or reliability etc ...) and this is often achieved with tricks like multi path connectivity to many "shelves" of high performance FC disks in a specific RAID configuration. (2) have fun performance tuning! The knobs available AND exposed to you along with the available instrumentation are UNPARALLELED! (IMHO Second only to Solaris dtrace) (3) *BE Patient with yourself* Things will get worse before they get better. This is where you need to develop a strong mental framework (I.e. get baselines, document changes, one change at a time, root cause analysis, thorough troubleshooting and clearly identifying where in the stack you are working on at the time) IBM storage gear (and almost equivalently, Sun gear) both taught me so much about systems -- I'm so lucky to have had the opportunity to work with a few of these systems in a large scale enterprise! Seems like you love this stuff, so you're going to have a lot of fun! 😅😊😂

As someone whos well versed in the ddr2 (I bought the wrong ram soo many times for my IBm x3650 M1 that I gave up - mainly due to bad eBay listings), I still have the same problem when buying ddr3 for my dell r210 ii and a Fujitsu tower server. I know the pain too well.

[@clabretro]

it's the worst

[@billmiller4800]

One thought: Try removing CPU 0 and then try installing CPU 1 while looking at the connector via the space from CPU 0. That may give you an idea why the second slot won't fully seat. It's possible that the planar board is flexing too much and won't allow the connector pins to slide all the way i, or one end of that monster connector is catching on something. If you stick your phone into the hole while recording video, it may give you a hint.

[@clabretro]

I should've mentioned in the video but after all the reseating I did while troubleshooting both processor assemblies were seating quite well by the end of it. So unfortunately something wrong with that processor assembly.

[@alexscarbro796]

With the system powered off, your could take that processor assembly PCB off its back plate and check it seats properly on its own. Then you know if it’s a connector issue or a mechanical fit issue.

[@MadITGeek]

Once again, the IBM gods thwart you from demoing LPARS first missing HDD connector. then not enough resources, then not enough power, now a unhappy server I've never seen that "extended DDR2" ever before, I blame IBM lol. I've seen ECC and DDR2 FB DIMMS yes, but not that stuff some thoughts: 1) on the HMC maybe a BIOS flash will expand its QVL/happy list of supported RAM, I've seen BIOS flashes allow for even more RAM than originally intended (happened on the R720 I used to own) yes, I know it changed its mind w the error you where getting the 2nd time but its food for thought. 2) I take it you have tried swapping the CPU modules around in the server and seeing if you still have the "it won't fully seat" issue 3) do the CPU themselves come out? (under the copper heatsink) check for pins (if it has any) in there and maybe reseat-it could be like a modern x86 platform where memory controller is on the CPU itself- if the CPU pops out try switching them around maybe its one of the POWER5+ itself, rather than the entire board 4) try the RAM from the smaller P5 in this one. 5) double-triple check you have the RAM installation order right 6) it might be the VRMs on the server...are they compatible with the smaller working one? yes, I work on Oracle Peoplesoft at work. ITS HORRIBLE AHHHHHHHHH -you can rename a file in MSDOS and it works but in Peoplesoft can you rename-NOPE!

[@clabretro]

All great thoughts. I did indeed swap the modules and I should've mentioned -- they both seem to seat just fine now. I think the CPUs do come off the assemblies, I'll have to try that. The fins on the broken one do seem a bit banged up so that's suspicious. I'll have to try all the other ideas!
