Talk:Hot swapping

Clarification required

The Blade server article says Blade servers are ideal for specific purposes such as web hosting and cluster computing. Individual blades are typically hot-swappable, which doesn't appear to fit with the hot swap versus plug distinction (interaction with software) in this article. Also, the article is talking about components of a computer whereas a blade server is a computer component of a cluster of computers.78.146.78.223 (talk) 12:51, 31 October 2008 (UTC)

Hot Swap vs Hot Swapping

Somehow a names needs to be chosen and hot swap and hot swapping need to be combined. Kail Ceannai 21:52, 2005 May 12 (UTC)

Hello? Merge anyone? 193.1.100.102 11:35, 18 August 2005 (UTC)

Kail, both of your links go to the same article, so, in effect, the two terms are already combined. --John R. Sellers 04:59, 24 August 2006 (UTC)

PS/2

It says PS/2 is not hot-swappable, but this is not true. I can hot-swap my keyboard and mouse on my Linux box. 70.52.147.11 00:14, 22 March 2007 (UTC)

Although rare, hotswapping PS/2 mice/keyboards may damage motherboard, most likely by blowing the fuse in-line with the power pin on the PS/2 connector. Having said that, I've also hot-plugged keyboards and mice before with no trouble. Sagsaw 19:16, 14 April 2007 (UTC)

Firewire: Cold or Hot?

In the section where true hotswappable and hotswappable where the OS must be notified by the user are compared, FireWire is used as an example of both types. Does anyone know which side is the correct one to place FireWire? I guess it should be on the "hot" side, as USB, but I'm not sure.

Afaict with both USB and firewire nothing bad will happen on a bus level if you just pull it out. However higher level stuff may not be ready if it isn't warned (for example with a hard drive the OS may still have data cached). Plugwash (talk) 02:17, 13 January 2009 (UTC)

IDE hot swap bays?

I was looking for information on how these work: are they reliable, do they slow down the drive? It would be great if someone who knows about this filled in some info on these devices. I know pretty much nothing about it, so I won't even try to mention them.

Damage

There are two aspects here: one is whether the device(s) break, and the other is whether they work. Devices that are not designed to hot swap may permanently break if plugged or unplugged while powered (example: PS/2). Devices that are designed to hot swap generally have hardware and software aspects. The user can assume that plugging and unplugged while powered will not break them. (Example: USB) But whether they will instantly, automatically "just work" all depends on many factors -- YMMV. -69.87.204.161 01:00, 19 March 2007 (UTC)

Component Shutdown and Redundancy

The sentence: "More complex implementations may recommend that the component be shut down, but there is sufficient redundancy in the system such that if a component is removed without being shut down, operation continues."

This seems a bit confusing to me however I want to avoid altering the meaning by changing the sentence structure. Does the following sound OK?

"Whilst more complex implementations may recommend that the component be shut down, there is usually sufficient redundancy to allow operation to continue uninterrupted while the component is taken offline." Sardaukar86 22:38, 13 November 2007 (UTC)

I don't think it is quite the point being made. I think the point is that if you have hot standby type configurations then although there may be a proper way to nicely swap over, the fail over mechanism should allow for an abrupt changeover. I'd quite like to see some source examples, as this is an important point. On a SAN, you have hot standby disks and you can go through a management procedure to implement the standby disk, swapping the offline disk without the need to shutdown the SAN. If you take out the broken but active disk without first taking it out of the set, would the system survive? (Answer: I don't know and I wouldn't try it!). Spenny 09:52, 14 November 2007 (UTC)

Removed cleanup tag, added refs tag

I changed some minor parts of the article, I think it no longer deserves the cleanup tag. However, as there are hardly any refs (I added the only one), i included the refimprove tag. Anyone who has some good sources on this field should look into this, the article seems solid otherwise Meertn (talk) 11:16, 25 December 2008 (UTC)

What means hot plugging?

Its not fully answered in the article introduction although hot plugging is redirected to this article --demus wiesbaden (talk) 00:11, 10 March 2009 (UTC)

Hot pluggable SATA/eSATA

I posted a question on hot swapping at Talk:Serial ATA:

Something that's not obvious from this article or the article on hot swapping... maybe someone can comment here, find cites, or update the articles with useful information. SATA itself by design is hot swappable, and yet there is minimal to no clear answer in these articles as to when and under what conditions a user can actually use that capability. For example: Under which operating systems? Which kinds of drivers, BIOS features, or specialized bridge/interface chips or cards are required? To what extent is effective hot swappability available in mainstream PCs using a SATA hard drive? Does unplugging or connecting a SATA drive to a modern power supply cause transients that may crash or harm the system? if so how does one power an external SATA drive (hot swapped or otherwise)? A comprehensive answer (either here or added to the article) would be useful, thanks.

PS/2 mouse

How to make XP recognise a hotplugged PS/2 mouse ? It does not detect it. I also tried the "Scan for new Hardware" option in Device Manager, but no results.

Merge

Maybe this should be merged into hot swapping? I've only been able to find three usable references. I also removed part of the lead that was copied from page 20 of LPI Linux Certification in a Nutshell. Feezo (send a signal | watch the sky) 09:55, 5 June 2011 (UTC)

• Support this article is just a smaller copy of the hot swapping article. CJ ^{Drop me a line! • Contribs} 18:15, 9 October 2011 (UTC)

 Done. The coldplug article has now been merged into the hot swapping article. Still needs some post-merge cleanup ... --DavidCary (talk) 00:57, 17 April 2014 (UTC)

Primary sources

Discussion moved from User talk:Edcolins#Primary Source concerns on Hot Swapping.

Questions about the changes you made removing my additions. I would like to correct whatever they are so we improve this page. Perhaps you can help. I have access to source material on this topic from and including some of the people who worked creating the technology.The content was factual and key to the subject. Not having it is one of the reasons Wikipedia receives much criticism. Please help. Deansmith750 (talk) 16:45, 19 November 2016 (UTC)

Thanks for your message. We need reliable, published secondary sources especially when it comes to claims about who invented the technology. The issue with "source material on this topic from and including some of the people who worked creating the technology" is precisely that such material qualifies as primary sources. See WP:PRIMARY. Are you aware of any secondary source about who actually invented the technology? --Edcolins (talk) 16:53, 19 November 2016 (UTC)

No question as to who invented and was issued copyrights. Lots of official proof from governmental agencies. Many historic records are easily accessible via searches and links. I have patent application, copyright history, trade mag stories, marketing materials and misc other records. If I cite the patent application (via gov office), trademark registration with history (via gov office), then the companies published materials and last industry materials showing they recognized "hotplug" was a registered trademark (naming the owner), do I need all these? Deansmith750 (talk) 22:13, 19 November 2016 (UTC)

The "official proof[s] from governmental agencies", including patent applications, are primary sources and should not be used alone. Could you please point to specific secondary sources available online, such as books, magazines, or scientific papers? Thanks. --Edcolins (talk) 11:15, 20 November 2016 (UTC)

I have not found extensive sources pro but none con to what I wrote. This is the reason I was forced to use these cites. They conform to known history. You likely know, using secondary only and not primary are not absolute requirements. I understand your original concern regarding use of only Primary and your assertion "governmental agencies, including patent applications, are primary sources". However, careful reading of the Wikipedia pages show "primary sources that have been reputably published may be used". And applying the fact to this case do show certain items published from these groups can be considered "Secondary". WP:SECONDARY says secondary may or may not be "independent" sources". WP:WIS defines governmental agencies as independent on these type of cases. There is a difference between filing a legal document or publishing a report and that an issuing of an order or determination. Simply in this case (Hotplug or hot swapping), the issue actually comes down the end result and looking at history. That is whether there was a copyright or patent issued (not filing records) and how the industry responded to the registration and technology created/disclosed. Facts I found: (1) The parties (primary sources) I identified claim to be inventors, published extensive materials, built and sold products containing the technology and no one has been found that has disputed this (all of this over many years). (2) No one other than who I identified claiming to have invented the technology. (3) No examples found until who I identified had products embodying use of the technology in the stated application. (4) no patent has been issued. Application was made but not completed by the parties I identified. Industry copied this technology, it has become a standard and today there are many examples of its implementation. (5) Copyright was filed and issued (registered) without objection. (6) Industry & governments accepted and referenced (crediting ownership). (7) Some in the industry avoiding using the term "Hotplug" and in some cases began calling the exact technology "hot swap" or "hot swapping". Please restore the the words and cites.
