Smart Monitoring PC Hardware Launched By NVIDIA

MojoKid writes "NVIDIA has just introduced a new open-industry standard for real-time monitoring and control of PC power supplies, chassis, and water cooling systems. Dubbed ESA, which stands for Enthusiast System Architecture, the company hopes the standard will be adopted across the industry. A new wave of ESA compliant hardware that can be monitored and controlled via a standard interface could ensue, like smart health-monitoring power supplies and other components, that would increase system stability and reliability. 'The ESA standard is built around the USB HID (Human Interface Device) specification and has been submitted to the USB-if HID subcommittee for discussion and approval. ESA is essentially a hardware and software interface that takes data collected by analog sensors and converts it to digital information that can accessed via software. Below are a handful of slides taken from an NVIDIA-produced presentation on ESA.'"

I hope the sensors work better than the ones in my HP printers. While it is may be interesting all the things they can detect, jam in tray 3, under fuser, etc. They really annoy the hell out of the users.

Well, it depends on how you use the printer. Here I'm sitting near a printer used to print product catalogs. 1000 pages left is a sign of that if there's no extra toner left, ordering some now would be a very good idea.

Really the right thing to do would be making the threshold configurable. Also depending on the cartridge, the precise amount of toner might be hard to

Re:

[lukas84]

It is configurable on newer HP printers (and Lexmark, and maybe more, but i don't know that).

And yes, i think 1000 is a pretty good point for a warning. Remember, we're talking about company printers here. Getting a replacement cartridge can be pretty complicated depending on the company, and even then the supplier might not have stock of your specific cartridge type (Probably only with more exotic, older printers).

I hope they work better than their own product [imageshack.us]. The CPU temp depicted is actually 51 degC, according to more accurate Core Temp and Intel TAT monitors. The nForce fan speed is actually ~5000 RPMs, but registers 11000 every few seconds without getting any louder. Occasionally the CPU core and FSB are drastically off.

Even with nVidia's integrated monitor, most "enthusiasts" (overclockers) end up trusting other independent utilities like SpeedFan and CoreTemp, and disregarding nVidia's monitor. Maybe that's w

Yeah, except there's no standard for I2C controllers (making software a nightmare - how many I2C controllers does lm-sensors need to support? How many are not supported?), likewise no standard for certain sensor types with I2C interfaces. (How many different temperature sensor drivers does lm-sensors have?)

IPMI Lite?

[drdanny_orig]

Wasn't this already accomplished w/ IPMI? At least in more expensive server hardware? What am I missing?

Re:IPMI Lite?

[Junta]

From my brief look at nVidia's site, it looks like it's more an internal standard than external. IPMI stops at the service processor. The service processor, in turn, used as many arbitrary busses/protocols internally to gather the data and report it back (and while the service processor *might* help you with fan-control versus throttling using OEM commands, the sensor interface strictly speaking only mandates reporting, not controlling). Such a system, for example, would do perfectly fine at reporting on all components explicitly integrated by the manufacturer. However, stick in an arbitrary graphics card, and no sensor value for it's temp/fan will appear as an IPMI-reported device. If a hypothetical standard existed within the case, monitoring may work better without having to buy a single-vendor solution that planned for all that, and you could hypothetically monitor and control arbitrary installed devices. Also, if intelligent about it, more tradeoffs can be made. When you can send instruction to both the GPU and it's cooling device, then for performance you could request that the cooling ramp up whatever it takes, but then go to acoustic and it would throttle the GPU instead of ramping up fans. An IPMI compliant BMC that was also ESA compliant might generate SDRs based on some sort of ESA-discovery.

nVidia isn't the only game in town talking about internal standards for this, Intel for one definitely has been pushing their own ideas in terms of moving standardization to the interior of the systems.

I've wanted something like this for a long time

[MonorailCat]

I currently have to use several programs and a manual fan controller to for half the capability this system offers. To read temps I have to use different programs for motherboard, case, and GPU, and several fans aren't even controllable, in hardware or software. I have little understanding of the temperature distribution in my case. Getting all this information and more into one integrated hardware/software package is a feature I'd gladly pay more for.

I'd love a nicely integrated solution. I don't have a high-end GPU right now but I went through all kinds of pain just trying to figure out if SMART reports correct data for my drives (more about this [latenightpc.com]). The short answer is that while I think it may have been wrong I still took the time to install some new quieter, high volume fans.

It seems like it's time for cooling solutions to enter the PnP age. Ever since MS strong-armed the industry into adopting Plug n Play it's been much simpler for computers to

Re:

[Michael Woodhams]

Likewise.

I use SpeedFan, but there is a lot it can't do:
I can't tell where the motherboard temperature sensors are.
It doesn't read temps or fan speeds or control fan speeds in the PSU.
It doesn't read temps or fan speeds or control fan speeds in the GPU (unless I plug the fan into a motherboard fan header.)
There is no standard hardware for attaching additional temperature probes.

In my case, some of this is moot - my GPU and PSU don't have fans. I take geek pride in having a quiet single fan system*. There ar

USB port usage...

[Ptur]

So you'll need a usb port for each item that you want to monitor (PSU, case, cooling,...).
Apart from usb port shortage, this also means more wires inside the case will be restricting the airflow.

Re:

[LWATCDR]

I don't see the need to use USB for this. Why not use I2C or SMbus which based on I2C?
It already exists and is more than fast enough. Seems like there is already a solution in place that may just need to be improved and not replaced.

Re:

[Ptur]

or SPI as a matter of fact....
 
The only problem is that I2C and SPI are not ideal on longer lengths, and certainly not for inter-component (MBPSU) communication.

Re:

[LWATCDR]

The problem with SPI for this application is that you need a CS line per device. That could be a lot of lines and or wires. Length of run shouldn't be a problem for the sensors in a PC case. The limit is depends on the clock speed but you can easily get a few meters. So with a 6 to 12 foot limit one has to wonder just how big your case is!
Motherboards already use the SMBus to monitor temps and fans. So why go with USB?

Re:

[Ptur]

true... lowering the clock helps. Still, I have seen enough problematic uses due to interference. There's a difference between using I2C or SPI on a PCB or using wires throughout a case. They simply miss signal integrity guarantee.

Re:

[LWATCDR]

Well except that SMBus which is I2C is already used on motherboards for temperature sensors and fans so we know that it works.

Is it interactive?

[ircmaxell]

This would be cool if it allowed real time interactivity with the devices rather than just monitoring. Think about it, being able to monitor and control devices remotely... It can be done now, but it's highly device dependant... With an open protocol, lmsensors would become much easier to install...

Ummm....SMB?

[Mateorabi]

Isn't this what the System Management Bus (SMBus) is for? SMB also has the advantage of not requiring hubs to provide multiple ports since its a true multi-slave two wire bus. (Multi master, too.) Why not just provide a breakout connector on the motherboard to chain more devices? It is 100-400kbps but most of the peripherals don't need to report more than a few bits per second of diagnostic info anyway.

SMBus is a mess

[Wesley Felter]

Today's motherboards use I2C/SMBus for sensor access, and it is a total mess. There are hundreds of models of sensor chips that need drivers, and there's no way to know the mapping from sensor numbers to the real world (which fan is "fan 0"?). Then some vendors add microcontrollers that are not on the SMBus and have totally undocumented interfaces (hello AIGuru). I haven't looked at ESA, but hopefully it solves some of these problems.

Re:Ummm....SMB? PMBus?

[Big Jojo]

Also PMBus [wikipedia.org], which standardizes much more of the relevant stuff.

For the record, SMBus maxes out at 100 Kbit/sec. PMBus allows 400 Kbit/sec, as does I2C. Neither of them is really intended to be a multi-master bus, except in the very limited sense that they define a way to send notifications from slave to master. (Though the alternative SMBALERT# mechanism seems much simpler... I think the "notification" thingie was designed to prevent a simple migration path from I2C, and promote fancier Intel southbrid

Why are they trying to put this in the Human Interface Device part of USB when it isn't for a human interface? I think having this functionality would be great, but I'm curious why it's proposed to be in HID.

Why not SNMP?

[smackenzie]

Why don't they fold more video monitors (and enthusiast monitors like water temperature of water coolers) into SNMP or SNMP2? (Or have they already?) Why do we need another standard?

SNMP is an industry standard, well-supported, flexible with multiple attractive interfaces... pretty sure it can be realtime and has the added bonuses of being networkable by default.

Re:

[mikkelm]

You want to use SNMP for hardware-to-hardware capability querying? Sounds like it'd make more sense to develop some sort of low-overhead SCMP (yeah, you got it right) that SNMP could leverage.

Re:

[fifirebel]

Ahem.

Maybe because SNMP is IP-based. Now you do not want to assign IP addresses for all the components inside your computer, do you?

And no, rendez-vous or mDNS (or whatever the name-du-jour is for IP autoconfiguration is at Apple today) is not an answer...

Re:

[smackenzie]

You don't need an IP for every component, just each computer. You can use your local IP 127.0.0.1 without issue. Really, nVidia should just be working to make this latency-free for local monitoring. By the way, each SNMP instance on each computer can record dozens (or even hundreds) of monitors. Generally with a good SNMP agent / manager, every time you register a device (like a Dell server or an IBM laptop) it adds dozens of things to monitor, some of them extremely low-level.

Re:

[DynamicPhil]

sorry for the potential OT.
> Now you do not want to assign IP addresses for all the components inside your computer, do you?

... actually, I'm thinking you might be on to something here.

Think IPv6 (where address space wouldn't be a problem) - and monitoring a farm of computers for something (example Fan speed). You could have query:able fans in different PC cases, all by using some sort of internal routing in the pc, some policys what's accessable (firewalling disks, making fans "read only, e.t.c.),

Upon further contemplation...

Again, this isn't a troll...I'm just a realist.

I just hope that the standard requires high-quality components, because I can see this backfiring. I have sold ASUS motherboards since I starting selling computers a few years back, and have had a lot of success (read: very very low RMA rate). Even though I choose to include only high-quality components, I have seen a situation where the motherboard -thought- it was running over temperature and began throttling itself (ASUS P4S800-X I think it was)...and this

On the second board Asus Suite reports the cpu temperature being 22C and the case being 33C. These numbers were completely off because even with standard cooling I couldn't bring the cor

Will it help with diagnostics?

[jandrese]

One thing the PC architecture is seriously lacking on is hardware diagnostics. If you have a machine that's crashing with when booted off of CD in your known-stable OS, it's a pain in the rear to track down what piece of hardware is causing the crashes. The almost complete lack of hardware diagnostics (work on a big iron machine once to see how good life can be with real diagnostic tools) means you're almost always reduced to just pulling out/swapping random bits of hardware until it stops crashing.
