Suggested for the RAID level configuration

Hallo,

I have a server 4core, 16 GB of RAM and 4 SAS 140 GB discks whith fiber channel EMC SAN. What is RAID level suggested for reduncancy and performance?

RAID 1 + (a single disc advanced to other uses)

RAID 10 (is really necessary for an ESX configuration?)

others

RAID 5 (suggested for VMFS, but not for a simple configuration, ESX)

RAID 6 (not suggested because that too slow)

Thank you

As for local storage (as opposed to the EMC SAN) I'd go with RAID 1 + 0 for optimal performance. If you have an EMC SAN you probably store most of your VMs on the San. Your local storage space will be for your ESX installation and perhaps a data store for testing. Thus, you do not want to go with a RAID that offered high performance and redundancy, even if she does a high-cost disk, because the size is not you primarily on local storage.

As for your EMC (Clariion AX regardless), you will want to cut LUN based on the needs of performance of your virtual machines.

LUN RAID 5 for your regular VMS

LUN RAID 1 + 0 for SQL (Oracle or Microsoft SQL SERVER) or machines virtual Exchange

Just my two cents on the views of storage vary, and the right answer for you depends on your environment.

  • Possible security for the Web-based Configuration

    My colleagues and I found something very interesting today... Despite having configured the FTP security settings (which have been confirmed to set up and in funcitoning. I can't open an FTP session to our remote target without specifying a username admin and the password) If you open the configuration tool based OR web in a browser, you can send via FTP to and from the target using the file remote browser without being connected to all! Everyone knows this?

    Apparently, these permissions are separate from FTP, but you can define these special permissions on the page of the security configuration for the web-based configuration utility.

  • Suggestions for a RAID card

    Header 1

    Currently I have an Adaptec RAID 3405 card, it is about five years old and about two of every three boot-ups, he negotiated one of the disks at half speed, i.e. 1.5Gps. To mitigate the problem, I've done as a "hot spare" HD Having replaced the cable without result maybe it's time to get a new card. 

    I want to do is get a RAID card allowing five internal hard drives (2 TB) and for future expansion also a SAS /... external connector. 

    Currently, there are three sets of external drive connected via eSATA and Sil3132 SATALink Controller. Latter is configured through external enclosures in RAID 5 and RAID0 respectively, so there is a single HD via the eSATA port.

    The system is of recent construction with an i7 950 and 24 GB of RAM. "' 'C' (System) drive is Raptor 10 K rpm WD, the" D "drive is a 1.5 to 7200 RPM, the 'G' disc is consists of four HDs Seagate 2 TB 7200 RPM drive 'I' is a Kingston SSD 128 GB which is used for caching. More combinations of external drive mentioned above. 

    In addition to change/upgrade the RAID card, I would get a late model SSD to replace my existing 'C' drive and use it to replace the existing "D". 

    Looking forward to your suggestions.

    See you soon,.

    Michael

    HI Mike,.

    We recommend to not to fill readers beyond 65%, depending on the performance degrades quickly at this point (beside SSD)

    I don't know that prejudice will agree.

    Intel Raid RS2BL080

    And then there is this one which is newer RS25DB080, but now you get up in the price of the Areca.

    Best software of management of each of them.

    Atto is the only other that we love.

    Nothing wrong with Areca.

    In all honesty I haven't used a LSI in 2 years and more. At one point they were my fav as comparable to those of other performance

    Even cheaper. We had some problems with them some time ago and stopped using their... also support was easy to get ahold of and well informed.

    Really, I don't know what the problem was with them...

  • Any suggestion for the option of compiling the Flex Mobile of the project in Flash builder (Blackberry platform)

    I use Flex mobile project type to create a stand-alone for targeting blackberry and android application both versions.

    Depending on the configuration of my test application works ok in blackberry tablet Simulator. As I am new to blackberry AIR application development if anyone can help me for the compilation of project I currently put for my application is good or not?

    When I checked the project-> properties-> Flex compiler, I found "Flex Hero" as compilation same SDK, so I'm trying to pass the value of the configuration option available, that it won't allow me to set the 'Blackberry Tablet OS SDK 0.9.1 for Adobe AIR"- any suggestions?

    The question above, see attached screenshot.

    Hey Dounibiligda,

    He was right to what you saw originally in your settings. the default SDK should be the flex SDK Hero. If you want to add libraries specific blackberry, you must manually import the qnx - screen.swc which will give you most of the libraries QNX which are skinned to resemble the appearance of the standard playbook.

    so to summarize, keep the default Flex Hero sdk and manually import the qnx - screen.swc to your project. Good luck!

  • Ask the suggestion for the installation of oracle 12 c standard edition

    Hi all

    I try to install 12 c standard edition on linux 6 for the first time...

    Could someone please suggest with the necessary steps to proceed.

    creation of user Linux, installation of the rpm, then installing the software...

    any suggestion expertise is much appreciated...

    Thanks in advance

    Kind regards

    Asking how to "get" oracle-RDBMS-server-12cR1-preinstall is not really logical. If you have a standard installation on the server to the latest version of Oracle Linux 6 update, all you have to do is:

    # yum install oracle-RDBMS-server-12cR1-preinstall

    RPM requires the configuration of standard yum string (oracle public yum) and the core Oracle UEK. Yet once again, the package does not contain software, but triggers the installation of the software based on the yum dependency checking.

  • Suggestions for CS5 new hardware configuration

    I'm investing in new hardware to run CS5 of the House and I would like your suggestions and comments on my list of requirements below.  My hardware budget is about $750 for the Tower, I already have a beautiful Vizio 20 "monitor, a generic wireless mouse and keyboard.

    The problem that seems to be running is that I don't want a game system performance or a home theater system.  So far, the only way I can hit on home theater systems is not to watch what anyone with TV remotes.

    Preferred manufacturers: Acer/Gateway or HP but consider others.

    The whole system will only work CS5, associated with scanner and printers and an internet connection USB720.  He won't be networked or you need wifi capabilities.  I do mainly web production, some print jobs and no video or audio editing (or if I do it will play only).  Most of the heavy lifting will be Photoshop and InDesign.

    I will install a Wacom Bamboo tablet also after CS5 is in place, and I noticed other assignments that I should download the latest drivers for the 64-bit operating system.

    My list so far:

    OS: Windows 7 Home Premium 64-bit (preloaded)

    Memory: 8 GB of RAM, + 2.2 GHz (by heart), Quad core configuration, but favorite DDR3 settle for DDR2

    HDD: 750 GB to 1 t or as much as I can get for the dollars

    USB ports: at least 2 more is

    Graphics card: am I locked in NVidia?  If so, the GeForce GT220 looks like standard

    Optical drive: DVD + - R/RW, not interested in Blu - ray

    Audio: everything that makes noise.

    Thank you for your ideas,

    Mary126

    Many users prefer ATI cards.  Personal choice because they

    both work well.

    If you have other data and scratch disks you have at least a C drive is huge, in my opinion.

    There are places that build custom computers, look on the web.

    HP doesn't have a computer with an eSata Port.  Dell computers from model 7100 do.  I bought a 9000.  It has space for 2 additional internal hard drives.  But was disappointed that there only 3 sata ports and one is used by the optical drive.  In order to check that it there are enough ports for what you want before you buy.

    Suggestion: Find a computer close to what you want and then call anywhere in the nearest big city and see if someone can build you one for a similar price.

  • Recommendations/suggestions for the material?

    Hi all

    I'm a little confused with what LabVIEW Embedded will work with. I read http://zone.ni.com/devzone/cda/tut/p/id/7066 , but that was not very useful because it tells me there are 260 aircraft but it lists only the 3 level 1 section (I guess that there are more than three). A research in the community gave no results. In the level 2 section, they are pointing to the keil device database, but it doesn't really help me either.

    I'm looking for a hardware platform like this http://www.gumstix.com/store/catalog/product_info.php?products_id=252 or this http://www.compulab.co.il/x270em/html/x270-em-datasheet.htm that will work with Embedded LV. I really don't want to design and build the hardware from scratch - I want to find something that will work for me for prototyping on shelf and it will also work for the small volumes of product.

    The problem is, how do I find something like that? Does anyone have the hardware recommendations? The cards Gumstix has an ARM A8 processor so I think he might be targeted by Embedded LV but I don't know. There is a post on this forum regarding the cards Gumstix but it refers to the microprocessor LV SDK and the replies to this post, it seems a very complicated if the process is impossible to implement the programming of LV on it. However, this post is old, and I understand that the SDK is no more.

    Any notice received with gratitude.

    Dr. Phil

    Hi Phil,

    As the Manu says, the best of the material of the plate for use with LabVIEW Embedded for ARM module are MCB2300, MCB2400, LM3S8962 Evaluation Committee.

    If I had to do your project, I probably used this material:

    Stellaris® Single Board Computer display Intelligent Module RDK

    LM3SXXXX family is easier to port of LabVIEW that family CAP because it uses pilot Stellaris.

    In addition, this material comes with examples that work on Keil µVision.

    However, you must create a new target and adds all the new features of LabVIEW. It can be difficult at the beginning.

    Best regards

    Nice day! I hope that all have a nice time. I have a HP Pavilion G60-458DX running Vista. I want to upgrade the wireless card/adapter to support 802.11n.  I would appreciate suggestions compatible.

    Thank you and enjoy all!

    Hi, John:

    Here is the link to the service manual for your laptop.

    http://h10032.www1.HP.com/CTG/manual/c02985882.PDF

    Looks like the only available wireless N card's network without WIRE Atheros AR9280 802.11a/g/n map.

    Please see Chapter 3, page 3-7.

    Make sure you get this model with the applicable B21 HP for the country you live.

    For example: If you live in the United States you need part # 482260-001.

    The part is available new from HP for US customers for $63,54.

    My advice would be at the request of the part # on eBay and get a model used but tested this card for a lot cheaper.

    Here is a list of the card used for people living in the US.

    http://www.eBay.com/Sch/i.html?LH_BIN=1&_sacat=0&_FROM=R40&_nkw=482260-001&_sop=15

    No other N Wireless card will work but this one.

    And the card must have the part number HP on it or it won't work.

    You also have a great day!
