  • Add a small RAID card? Will it help overall stability and performance of my nine hard drives?

    - by Ray
    Hi, Will I get any extra genuine added performance and RAID stability if I insert a basic RAID card into a PCI-E x1 slot? I am considering the Adaptec 1220SA - 2 port SATA , pci-express (1x) , raid 0/1. Ok it only supports two SATA drives. Purpose is to help support the eight internal hard drives (1TB each), a DVD drive and an external e-SATA connected 2TB hard drive - by dealing with two of the internal hard drives. My current configuration of eight internal 1TB Barracuda (7200.12) SATA hard drives, one external 2TB SATA Western Digital Green Drive (e-SATA) and one DVD drive can already be supported by the Intel P55 & JMicron controllers on the ASUS motherboard : the Intel P55 (controls six HDD; configured as three x RAID 1), and the JMicron (controls two HDD as one RAID 1, as well as the DVD drive and the external SATA drive via the motherboard's e-SATA port (controlled by the JMicron)). Bigger picture details : I have an ASUS motherboard designed for the LGA1156 type processor and it includes the Intel P55 Express Chipset and JMicron. I am using the Intel Core i7-870 processor, and have 8GB DDR3 (1333) memory (four x 2GB Corsair DIMMs). Enough overall power. The power supply is more than sufficicient for the system. Corsair AX850. The system will never need the full 850 watts (future : second graphics card). The RAID card would provide hardware RAID 1 for two of the eight intrnal drives. It would either reduce the load on : the Intel P55 firmware RAID support, or replace the JMicron controller's RAID 1 set. I am busy installing the above configuration using Windows 7 Ultimate 64-bit as the OS. The RAID card is a last minute addition to the plan. Is it worth spending the extra R700 - R900 on the Adaptec 1220SA, or equivalent RAID card? I cannot afford to spend yet another R2000 - R3000 on a RAID card that would support many SATA2 hard drives, with a better RAID, example the RAID 5. My Issue & assumption : I am trusting that the Intel P55 chipset can properly handle six drives, configured as three * RAID 1. I am assuming that the JMicron can handle, using its RED SATA ports, one RAID-1 (two HDDs). The DVD drive connects to the JMicron optical SATA port 1 (white port 1). White port 2 is not used. The e-SATA connection is from the JMicron straight to, and through the motherboard - to an on-board (rear panel) e-SATA port. Am I being a little hopeful in only using the on-board Intel P55 and the JMicron? Is it a waste of money to install a RAID card that handles two SATA2 drives? OR Is it wisdom to take the pressure a little off the Intel P55? Obviously I am interested in data security, hence RAID 1, not RAID Zero. RAID 5 would be nice. The CPU, Intel Core i7-870 will provide the clout. Context to nine drives : I am using virtualisation with Windows 7 Ultimate. Bootable VMs. The operating system gets a mirror. Loaded apps gets a mirror. The current design data is kept in another mirror and Another mirror is back-up one and / or VM territory. Then the external 2TB drive (via e-SATA) is the next layer of data security and then finally, I use off-site data security. Thanks.

  • invalid context 0x0 under iOS 7.0 and system degradation

    - by Alex
    I've read as many search results I could find on this dreaded problem, unfortunatelly, each one seems to focus on a specific function call. My problem is that I get the same error from multiple functions, which I am guessing are being called back from functions that I use. To make matters worse, the actual code is within a custom private framework which is being imported in another project, and as such, debugging isn't as simple? Can anyone point me to the right direction? I have a feeling I'm calling certain methods wrongly or with bad context, but the output from xcode is not very helpful at this point. : CGContextSetFillColorWithColor: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability.

At which point they spawn multiple times, until the keyboard won't provide any input. Touch events are still registered, but system slows down, and eventually may lead to unallocated object errors.

  • CPU Test Similar to Memtest?

    - by Nick Whaley
    I need an easy way to do system stability tests. I have come to rely on Prime95 which does a fantastic job of proving stability (or instability) very quickly; but it requires an OS installed. I would like something like Prime95 that stresses both CPU and RAM (maybe PCI-Ex bus also?) but runs in a nice bootable binary like Memtest86+ does, so I can boot it from a thumbdrive. Does such a thing exist?

  • OpenSSL Versions in Solaris

    - by darrenm
    Those of you have have installed Solaris 11 or have read some of the blogs by my colleagues will have noticed Solaris 11 includes OpenSSL 1.0.0, this is a different version to what we have in Solaris 10.  I hope the following explains why that is and how it fits with the expectations on binary compatibility between Solaris releases. Solaris 10 was the first release where we included OpenSSL libraries and headers (part of it was actually statically linked into the SSH client/server in Solaris 9).  At time we were building and releasing Solaris 10 the current train of OpenSSL was 0.9.7.  The OpenSSL libraries at that time were known to not always be completely API and ABI (binary) compatible between releases (some times even in the lettered patch releases) though mostly if you stuck with the documented high level APIs you would be fine.   For this reason OpenSSL was classified as a 'Volatile' interface and in Solaris 10 Volatile interfaces were not part of the default library search path which is why the OpenSSL libraries live in /usr/sfw/lib on Solaris 10.  Okay, but what does Volatile mean ? Quoting from the attributes(5) man page description of Volatile (which was called External in older taxonomy): Volatile interfaces can change at any time and for any reason. The Volatile interface stability level allows Sun pro- ducts to quickly track a fluid, rapidly evolving specif- ication. In many cases, this is preferred to providing additional stability to the interface, as it may better meet the expectations of the consumer. The most common application of this taxonomy level is to interfaces that are controlled by a body other than Sun, but unlike specifications controlled by standards bodies or Free or Open Source Software (FOSS) communities which value interface compatibility, it can not be asserted that an incompatible change to the interface specifica- tion would be exceedingly rare. It may also be applied to FOSS controlled software where it is deemed more important to track the community with minimal latency than to provide stability to our customers. It also common to apply the Volatile classification level to interfaces in the process of being defined by trusted or widely accepted organization. These are generically referred to as draft standards. An "IETF Internet draft" is a well understood example of a specification under development. Volatile can also be applied to experimental interfaces. No assertion is made regarding either source or binary compatibility of Volatile interfaces between any two releases, including patches. Applications containing these interfaces might fail to function properly in any future release. Note that last paragraph!  OpenSSL is only one example of the many interfaces in Solaris that are classified as Volatile.  At the other end of the scale we have Committed (Stable in Solaris 10 terminology) interfaces, these include things like the POSIX APIs or Solaris specific APIs that we have no intention of changing in an incompatible way.  There are also Private interfaces and things we declare as Not-an-Interface (eg command output not intended for scripting against only to be read by humans). Even if we had declared OpenSSL as a Committed/Stable interface in Solaris 10 there are allowed exceptions, again quoting from attributes(5): 4. An interface specification which isn't controlled by Sun has been changed incompatibly and the vast majority of interface consumers expect the newer interface. 5. Not making the incompatible change would be incomprehensible to our customers. In our opinion and that of our large and small customers keeping up with the OpenSSL community is important, and certainly both of the above cases apply. Our policy for dealing with OpenSSL on Solaris 10 was to stay at 0.9.7 and add fixes for security vulnerabilities (the version string includes the CVE numbers of fixed vulnerabilities relevant to that release train).  The last release of OpenSSL 0.9.7 delivered by the upstream community was more than 4 years ago in Feb 2007. Now lets roll forward to just before the release of Solaris 11 Express in 2010. By that point in time the current OpenSSL release was 0.9.8 with the 1.0.0 release known to be coming soon.  Two significant changes to OpenSSL were made between Solaris 10 and Solaris 11 Express.  First in Solaris 11 Express (and Solaris 11) we removed the requirement that Volatile libraries be placed in /usr/sfw/lib, that means OpenSSL is now in /usr/lib, secondly we upgraded it to the then current version stream of OpenSSL (0.9.8) as was expected by our customers. In between Solaris 11 Express in 2010 and the release of Solaris 11 in 2011 the OpenSSL community released version 1.0.0.  This was a huge milestone for a long standing and highly respected open source project.  It would have been highly negligent of Solaris not to include OpenSSL 1.0.0e in the Solaris 11 release. It is the latest best supported and best performing version.     In fact Solaris 11 isn't 'just' OpenSSL 1.0.0 but we have added our SPARC T4 engine and the AES-NI engine to support the on chip crypto acceleration. This gives us 4.3x better AES performance than OpenSSL 0.9.8 running on AIX on an IBM POWER7. We are now working with the OpenSSL community to determine how best to integrate the SPARC T4 changes into the mainline OpenSSL.  The OpenSSL 'pkcs11' engine we delivered in Solaris 10 to support the CA-6000 card and the SPARC T1/T2/T3 hardware is still included in Solaris 11. When OpenSSL 1.0.1 and 1.1.0 come out we will asses what is best for Solaris customers. It might be upgrade or it might be parallel delivery of more than one version stream.  At this time Solaris 11 still classifies OpenSSL as a Volatile interface, it is our hope that we will be able at some point in a future release to give it a higher interface stability level. Happy crypting! and thank-you OpenSSL community for all the work you have done that helps Solaris.

  • What Sorting Algorithm Is Used By LINQ "OrderBy"?

    - by Mystagogue
    Evidently LINQ's "OrderBy" had originally been specified as unstable, but by the time of Orca it was specified as stable. Not all documentation has been updated accordingly - consider these links: Jon Skeet on OrderBy stability Troy Magennis on OrderBy stability But if LINQ's OrderBy is now "stable," then it means it is not using a quicksort (which is inherently unstable) even though some documentation (e.g. Troy's book) says it is. So my question is: if not quicksort, then what is the actual algorithm LINQ's orderBy is using?

  • Are the Ubuntu ISO images updated From release .ubuntu.com

    - by tijybba
    Just got idea from this(may not be related though) question however. Are the ISO images from the official site updated with updates in Core Ubuntu system , like Kernel Updates , desktop Environment Updates(unity), i mean Updates of BASE system including X-org, Office suite, Package Manager , Update manager or Gnome Base Modules, those released in update Branches like precise-Updates branch. The reason i am asking this is , if i download the ISO image of Ubuntu 12.04 Say after two or three months from release , i have to do an update of approximately 200~300 MB's size. So why are these ISO images not updated to recent updates, i am aware that all of the components are not updated at the same time , but let's say after One month from actual release ( Both LTS and normal releases), the updated components can be added to form a Updated ISO in regular intervals, which provides new users to use latest versions and features with improved stability and less bandwidth Consumption. I am not mentioning the idea of comparison to Rolling Release , or External PPA's added updates , and neither Netinstal but the ISO of updated Packages .This can be provided as optional download. Since my question is within the boundary of Official updates releases so stability could not be the reason. I guess there are custom packagers out there , but having an official option would be better. It helps in distributing Newest ISO OS which impresses a lot new users , since it makes availability of newer features and a faster system ofcourse. Another reason of asking this is here. Edit: Since almost all new (Desktop) users download the Default ISO's having one or few issue , which may have been corrected in following updates. But most of new laptop users i encountered gave up because of it , so should i suggest ,for laptop not listed on Certified H/W list , to try daily Builds , if needed.

  • Having to Toggle Between Two Sets of Video Drivers

    - by Maarx
    So, I've got a Win7 64-bit gaming PC with GTX 260's. Recently, StarCraft 2 had an issue with flickering, which NVidia fixed with a new set of drivers. However, these new drivers induce unplayable graphical errors with Neverwinter Nights 2, something me and my friends still play from time to time. I am seeking advice on the "best" way to rectify this situation, to be able to switch between two driver releases, without compromising the stability of my system (if Windows stability isn't an oxymoron). I'm wondering if Windows 7 is structured in such a way that I can constantly reinstall these two sets of drivers back and forth overtop each other, possibly six or eight times a day, without very quickly driving myself to reformat to maintain that "just like new" performance. I'm loathe to have to reformat the drive and maintain two copies of the operating system, but I'll do it if I have to.

  • recommendations for a lightweight linux distribution for a test server

    - by Jack
    I'm planning on setting up a test server to experiment with some application servers (tomcat/jboss/...) and with some portals. Now the machine I've set aside for this is lightweight CPU/GPU wise(Atom D510, 4 gigabyte ram, 500 GiB hdd, onboard GPU). But it should suffice for most things, I'm more interested in the stability of JBoss/Tomcat for my purposes than the stability. However I'm having a bit of trouble picking an appropriate distribution size/performance/setup time wise/security wise since it seems I can't sneeze without another distribution popping up. I've been thinking about going for Fedora since I've read that that distribution has been optimized for Atom, but I'm not really familiar with it. My experience with Linux has mostly been limited to Ubuntu and some tinkering with puppylinux. I'm not afraid to get my hands dirty using the command line. I'm not planning on starting a discussion per se, mostly the pros/cons that people have encountered with some distributions

  • Will final version of 12.04 use the power management changes found in kernel 3.3

    - by Luis Alvarado
    I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are not all found in the kernel 3.2. My question then is: Will this updates in 3.3 be somehow pulled into the 3.2 kernel used for Ubuntu 12.04?

  • How can I load .FBX files?

    - by gardian06
    I am looking into options for the model assets for my game. I have gotten pretty good with Blender, and want to use C++/DirectX9 (don't need all the excess from 10+), but Blender 2.6 exports .fbx not .x (by nature) and supposedly what is exported from Blender to .x is not entirely stable. In short how do I import .fbx models (I can work around not having animations if I must) into DirectX9? Is there a middleware, or conversion tool that will maintain stability?

  • Article Sharing &ndash; Windows Azure Memcached Plugin

    - by Shaun
    I just found that David Aiken, a windows azure developer and evangelist, wrote a cool article about how to use Memcached in Windows Azure through the new feature Azure Plugin. http://www.davidaiken.com/2011/01/11/windows-azure-memcached-plugin/ I think the best solution for distributed cache in Azure would be the Windows Azure AppFabric Caching but since it’s only in CTP and avaiable in the US data center David’s solution would be the best. Only one thing I’m concerning about, is the stability of windows verion Memcached.
