Re: FreeBSD on SSD on ASUS P5KPL-C
Thank you very much for your work on this. I have found this conversation and your article very informative. I've already installed W7 on my SSD but I let the installation program create the windows (MBR) partition. I'm going to install FreeBSD 9.1 as soon as it is ready so I want to ask if it is straight forward if I follow your instructions for creating the bsd slice and partitions, or if I need to check anything in order to get the correct alignment?

ZFS or other filesystems will also benefit from block alignment, but the methods to get there can be different. The step of using gnop is meant to trick zfs into believing the disk has 4K sector size to improve performance, which I would think zfs would be able to figure out by talking to the disk. Unless ZFS is put on a bare, unpartitioned disk, configuration for performance is better left to the user. It's a pain to correct automatic configs when they guess wrong. Does partitioning hide the sector size or would the step of aligning the partition start to a 4k sector unhide the 4k size? Or are these steps just a waste of time? It's not about hiding the device's native block size, it's about getting the filesystem to do aligned I/O so the device can just read or write a single 4K block instead of part of one and part of another. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

My final question would be : Seeing as the HDD only has a SATA connector, this would mean that the SSD part already has a memory control device that regulates access to that sector, whether it is a plain read-cache or not. This would imply that FreeBSD could communicate with the HDD normally, through the SATA connector, just like any regular HDD. indeed. Such a drive is a good idea, but complete lack of documentation (how it operate) is not. You have to guess how this SSD-cache works because it is not documented. the other thing is erasing data.

If I'm wrong and it should really be two units in one, your idea would work. Install FreeBSD to the SSD part and apply the known optimizations.

Re: FreeBSD on SSD
Hello again everyone. First of all, I want to address a thank you for your responses. They have been unexpectedly numerous and have clarified some aspects of my inquiries. The read-cache idea is very sound, mainly because by using it this way Seagate would not have to create a special set of instructions for installing and using the HDD. My final question would be : Seeing as the HDD only has a SATA connector, this would mean that the SSD part already has a memory control device that regulates access to that sector, whether it is a plain read-cache or not. This would imply that FreeBSD could communicate with the HDD normally, through the SATA connector, just like any regular HDD. Based on that sequence of thought, and the fact that on the System Requirements page of FreeBSD it says : * * *4.4.1.* What kind of hard drives does FreeBSD support? FreeBSD supports EIDE, SATA [...], am I right to assume that there should be no incompatibility or conflict between the OS and the drive ?

According to the documentation on the Seagate web page (which I mentioned in my previous message), the drive talks to the system like any other SATA drive. The fact that it uses an internally controlled SSD for caching (including management of that disk by the disk's firmware!) does not make any difference to the operating system.

Re: FreeBSD on SSD
The read-cache idea is very sound, mainly because by using it this way Seagate would not have to create a special set of instructions for installing and using the HDD. I don't think that this drive cache is smart enough to really cache needed things and not flush that cache with useless data too often. i personally would prefer that drive to show up as 8GB disk and 750 GB disk. It would be easy to fit most of /usr in 8GB with even large set of software installed. when out of space then use softlinks and move not very used things (eg. documentation, non-yours locales, examples, some linarly accessed big files etc.) to disk. My final question would be : Seeing as the HDD only has a SATA connector, this would mean that the SSD part already has a memory control device that regulates access to that sector, whether it is a plain read-cache or not. This would imply that FreeBSD could communicate with the HDD normally, through the SATA connector, just like any regular HDD. indeed. Such a drive is a good idea, but complete lack of documentation (how it operate) is not. You have to guess how this SSD-cache works because it is not documented. the other thing is erasing data. You want to sell that drive and clear your data by dd if=/dev/zero of=/dev/disk bs=1m but does it clear SSD cache? i don't think so. Someone sophisticated enough would perform raw read of cache chips and get cached data, which can actually be the most important part (things you work on often). ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Back around 2005 / 2006, we were using a bunch of Soekris 4511's, IIRC, running NetBSD and a network IDS we'd been working on, which possibly generated 100s of MB to a few GB of logging per day. Whoever did the initial setup didn't realize that the flash cards of that timeframe were limited to 10K writes or so, and after a few months you started getting 16K chunks of old logfile data, or 16K chunks of new and old logfile data corrupted together-- looked to be a binary OR of the 0 bits. Nothing reported that writes were failing-- evidently the flash cards didn't notice an error and thus didn't report it back to the system. Switching /var to tmpfs resolved the issue for us. From what I understand (a quick review of wikipedia helps :), modern flash cards are now typically rated for 100K writes, include ECC bits to actually correct or at least detect errors and try to remap bad blocks to unused blocks, and implement wear-leveling techniques of varying degrees of effectiveness.

I fail to see why a manufacturer would *not* want your hardware to wear out faster, since that would mean you would have to buy replacement hardware sooner. Can someone please enlighten me on the dangers faced by those who opt to get their laptops installed with SSDs? In many cases, particularly where there is quite a lot of RAM installed in the system and where people use a netbook the way it was intended to be used when designed (typically involving a lot of Web browsing and not much else), SSDs might be the best option -- especially given the rapid obsolescence of low-performance, ultra-portable units. If you expect your hardware to last a long time, overrun physical RAM into swap space a lot, and (as you might with FreeBSD) compile code an awful lot, the heavier storage-write load might make more of a difference in the expected lifetime of the hardware. With FreeBSD, installing everything from binary packages can help mitigate the possible problems of shortening the life of your SSDs. Of course, if you care about having lots of storage, it's worth keeping in mind the fact that SSDs still cost a lot more per gigabyte of storage than rotating magnetic media (HDDs). I personally have one, with a Toshiba 128GB SSD (THNS128GG4BAAA-NonFDE). I am running Windows 7 on it. Should I stop and buy a SATA disk?:) Probably not. You already have the SSD storage, and its improved performance for many operations (as well as improved durability under stress in the short term) can still be of benefit.

For example, while you might consider it bloat to have drivers for modern wireless N protocol cards, many other users have a real need for them. This would not be bloat in any regards. Bloat refers to software that raises hardware requirements (or also software requirements) for NO benefit at all. For example, a program that re-implements existing functionality, but does it in a way that the final result becomes much slower, more vulnerable to attacks or generally more insecure, would be bloat. This is a relation between what software provides and what it requires for that in chance. A term in relation is overall usage speed which contains things like system booting time, program loading time, time needed for interaction and so on. The corresponding equation would be software requirements speed = --- hardware resources which shows that if you increase both parts, the result will stay constant. This is the explaination why a 386 with 40 MHz and GEOS (Geoworks Ensemble) does not feel slower than a current PC with plentycore processor and tenmelonhundred Gigahertz and tons of RAM, running Windows and the MICROS~1 office suite. This assumes that people do the same things with both example systems, as they usually do (here: generic example of word processing). You can easily see that working (!) hardware support would not be bloat. In opposite, it would be very WELCOME to have support for wireless N protocol cards on ANY operating system. But there are reasons why it is NOT the case. This means that bloat is not specific to an OS. There are systems that traditionally emphasize the development of bloatware for their own marketing reasons, but you can also find bloated software on efficient and secure systems.

Oh, and you don't really need it when you already know the keyboard shortcuts, which is ESSENTIAL for serious work (because it's faster). :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

For some, Office is unusable due to the new Ribbon interface and libreoffice is the usable office suite due to its familiar menus. New, as in four years old? That is one of the worst straw man arguments I have heard in a while. You're refering to when the UI has been issued as being new. I'm refering to how users recept it TODAY. In many business settings, you won't see any of the new stuff MICROS~1 has to offer. This Windows XP is still VERY present, and a common office application is the predecessor with the traditional menues. Many user complain about the Ribbon and refuse to use it, as they had a hard time learning menues (and the changes within them from program version to program version). And now something new... that's too complicated. That's why I was using new as this kind of nonfamiliar interface is considered new TO THEM. In any case, In 2008 OpenOffice.org started the project Renaissance to improve the user interface of OpenOffice. So far the prototypes of the project are frequently seen as similar to the ribbon interface. Providing the TRY of the same is often inferior to providing better. But users do not want better, they want the same as they prefer consistency in usage, implying that nothing new has to be learned. Obviously, the use and customization of any software is a personal experience. However, if the use of the ribbon is beyond your abilities, [...] Preferences. Abilities have nothing to do with it, except we are talking about niche users (who are out of scope anyway), such as blind users who could read menu text through a Braille readout, but can't identify images (without any text) by that means, which implies that a pictural interface which is contextually changing is absolutely unusable for them. [...] and I am assuming that you are aware that the ribbon can be hidden, modified and that there are many add-ons available that can be used to manage it, then so be it. I'm not using any MICROS~1 stuff at all, so my experience can be seen as limited. I would rather work with an application with a minor annoyance, and I do not find the ribbon to be one, then to use a less robust application. I don't think robustness is important for end users in the home sector, as bleeding edge is preferred. Robustness is very important for corporate users. Again, it is up to the end user to ascertain their requirements and find the tool that is best fitted to that job. No. End users do not try or find anything, or make judged considerations. They use whatever comes preinstalled, or they use what they know from their work place (traditionally by obtaining a pirated copy of whatever it is). In any case, I am quite confident that your condemnation of the ribbon is totally based on your reading of Slashdot and other similar documents and not from any personal experience. I have never read anything on Slashdot, sorry. Should I? :-) My personal experience is limited in helping users who come from a menu background and feel that the constant re-learning a contextually changing interface that is based upon pictural elements instead of WORDS is limiting their productivity. This was the chance for me to try to use the Ribbon interface, and I didn't feel it is THAT BAD. There are, however, applications where this kind of interface, if consistently used, would be a benefit for the user. I suggest you have a look at this: http://toastytech.com/guis/win72.html It's part of the Windows 7 article of the GUI Gallery and contains a very nice summary of user perception of the Ribbon, NOT in relation to MICROS~1's office programs in this case. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Obviously I'm not talking about myself having problems with it since I've used all sorts of different UIs over the years and can learn new interfaces quickly. You seem to be forgetting that most people don't upgrade very frequently: I wouldn't be surprised if lots were still running Office 2000. I worked in an RD environment and even there people were steadfastly ignoring Vista and even 64-bit Windows even 3 years after it was released - I had to keep running 32-bit XP. The problem is that less technically-literate people have problems with _certain_ operations which were simple in the past - printing for example now takes several clicks during which the screen changes each time. For people who get confused when icons move on the screen the context-sensitive nature of it can be rather difficult to learn. With large screens and people who don't have the baggage of expecting things to work a certain way I do think Ribbon is better: for example I recently started using Access 2010 and found it rather easy to find how to do things like exporting to SQL Server 2008, which would previously have been buried. Also, the way traditional sub-menus work in Windows is really awful for people who don't have accurate mouse skills - move the mouse outside the menu and it disappears. The Ribbon solves this problem. -- Bruce Cran ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

I fail to see why a manufacturer would *not* want your hardware to wear out faster, since that would mean you would have to buy replacement hardware sooner. Can someone please enlighten me on the dangers faced by those who opt to get their laptops installed with SSDs? In many cases, particularly where there is quite a lot of RAM installed in the system and where people use a netbook the way it was intended to be used when designed (typically involving a lot of Web browsing and not much else), SSDs might be the best option -- especially given the rapid obsolescence of low-performance, ultra-portable units. If you expect your hardware to last a long time, overrun physical RAM into swap space a lot, and (as you might with FreeBSD) compile code an awful lot, the heavier storage-write load might make more of a difference in the expected lifetime of the hardware. With FreeBSD, installing everything from binary packages can help mitigate the possible problems of shortening the life of your SSDs. Of course, if you care about having lots of storage, it's worth keeping in mind the fact that SSDs still cost a lot more per gigabyte of storage than rotating magnetic media (HDDs). I personally have one, with a Toshiba 128GB SSD (THNS128GG4BAAA-NonFDE). I am running Windows 7 on it. Should I stop and buy a SATA disk?:) Probably not. You already have the SSD storage, and its improved performance for many operations (as well as improved durability under stress in the short term) can still be of benefit. Just be sure you know when the usable lifespan of your SSD approaches, keep good backups (as you always should anyway), and be happy. You'd surely be happier with a better OS on it, though -- right? -- Chad Perrin [ original content licensed OWL: http://owl.apotheon.org ] pgprvo07hiHkt.pgp Description: PGP signature
FreeBSD and SSD drives
Hi, Is anyone using SSD drives on freeBSD server systems? I'm attracted by the performance increases i've seen on both my desktops and laptops (quite amazing and easy upgrade if you've not tried).. I see from here http://en.wikipedia.org/wiki/TRIM#Operating_system_and_SSD_support that full TRIM support only comes in 8.2, I'd be interested to here peoples opinions on best uses for SSD, general purpose applications such as databases , webservers etc will benefit obviously, but i'm also curious as to disk intensive applications such as mailq's, spamassassin etc? (I presume here the lack of TRIM may degrade performance rapidly?) thanks Paul. -- - Paul Macdonald IFDNRG Ltd Web and video hosting - t: 0131 5548070 m: 07534206249 e: p...@ifdnrg.com w: http://www.ifdnrg.com - IFDNRG 40 Maritime Street Edinburgh EH6 6SA - ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
