Does anyone use this switches in a data center?

I have an interest in the switches of SG-300 or SG-500 small businesses for small and moderate use.

These are rack switches, but my question is if someone is actually using them in a rack of data center with public servers rather than catalysts?

I understand that they are small business units, but they would hold the heat, vibration in a rack? How do they practice?

I have an older catalyst, it costs less than new now that some of this small business ones, but I really need gigabit for internal LAN traffic ports and my DC tells me none has this unit to small businesses in their DC, it is not normal to use because they are not high-performance switches. IM worried to go small businesses who are actually Linksys device and not Cisco. I have some Linksys devices for personal use and at home and they are still in years. But I Don t know how they perform outside of this environment. I need to stay under $ 1000 per switch.

They would fail in a few months? Can be clustered (2 switches) so if one fails the other take the network up until I have replace the failure? If so, I could take the risk, but one dying switch would be a disaster.

My needs are low speed gigabit between the servers for backup and storage, but usually less 50 Mbit on the public Wan. These switches are really only for small office use or if they work very well with the servers in an institution? If so, I'd love to hear some real experiences, everyone I ask most of them said not to go with the switches, but then why are they still rack? They can´t be this bad or that they are not really designed for 24/7 usage?

I'd appreciate some experiences with the amount of traffic you are passing on them and for how long (months) because I Don t know anyone use so far in a remote installation.

Catalyst has shared backplanes and ASICS. SX300 and SX500 series does not work. If you do not need things like the protocols of the road (BPG, OSPF, IS - IS), VTP, CEF then these switches are very good.

The switch has generally not hardware failure unless it is due to external voltage problems. A real failure, the MTBF is probably 4 or 5 years old, and I say this because the SX300 was not of the most and I've honestly never seen a die with the exception of power problems (storms, power surges, etc.). I saw ports to die only once and a while but that does not matter much because the switches are hardware to life with replacement free advanace...

If you plan to use these switches as a Ridge with high throughput, especially in layer 2, I seriously doubt you'll break this thing.

I am not yet sold on the robustness in environments of layer 3 but as a core for sub 300 people is a good switch. In response to another concept, the SX500X switches supports VRRP.

  • "Compress this drive to save disk space"... does anyone use this?

    In the old days of big hard drives being expensive, it was
    understandable that some people did, despite the risk. But today,.
    It's a very bad thing to do, for two reasons:

    1. the discs are today very expensive and therefore the amount of disk space
    You can save in compression, measured in dollars (or whatever your)
    the local currency is) is low.

    eat.
    Normally, if you have a hardware problem with a small amount of disk
    space, you will lose the files as disk space in. The
    the rest of the car remains legible. But if all of the disk is
    compressed, indeed the entire disk is in one file and the
    any hardware problem results in loss of * everything * on the
    drive.

  • Does anyone have a good experience, export data from cubesavvy?

    Merry Christmas / Happy holidays everyone.

    Does anyone have a good experience, export data from ASO using cubesavvy?

    I tried but the filters don't seem to work.  I entered about 9 filters - with the members and parents to 9 dimensions.  However, the native text file that it created does not seem to use these filters.  I select 'Member = FY15' but it has exported the native file, had FY12.  I think this tool takes the native text file it generates and create a report of the column from it.

    http://www.cubesavvy.com/parse-ASO-export-to-columns/

    We use it because our financial report and the Smartview crashes when we tried to explore the zero level for Dept (we have more than 5 thousand), projects (more than 5,000) and accounts (more than 200).  It looks like a simple report.  Our report EN used to support 20 minutes now it crashes.  We must perhaps compact contour and use the motion tracking.

    R,

    David

    Hi David,

    Harry Gates here, the developer of cubeSavvy. Dozens of people successfully using the export ASO Analyzer feature, with and without filters. This includes a few very large companies with big data and the large contours (100s of exports of GBs and hundreds of thousands of members). If the filters are not limit the written lines, it has been my experience that the names of typical members in do not match those of the file.

    You can reach me at [email protected] if you have any other questions. You can also send me your otl and export, if they are not too sensitive and I'll take a look.

    Kind regards

    Harry

  • Does anyone use iCloud for everything?

    Does anyone use iCloud as your main service (i.e. for synchronization, documents of cloud and primary email address)? I mainly use it as my primary service, but finds that she has its drawbacks, especially when it comes to Mail and web messaging on icloud.com - it is a bit old and lack of functionality.

    Wonder if anyone has experiences and possible suggestions to fix/improve the service?

    I use my account for all iCloud. It is my main email account, iMessage account, allows you to synchronize my calendars, is my main calendar, synchronize and stores my contacts, contains most of my personal documents (although I also use the box, Dropbox and OneDrive).

    I had no problems with it. What features Miss do you? I rarely use iCloud.com. I mainly go there through the apps on my iPhone, iPad, Apple Watch and Mac.

  • Procurve switches update: should I shut down VMs on cluster that uses this switch?

    I've update the firmware on our Procurve switch soon. It need to restart this switch. Should I close all the virtual machines on the cluster that this switch is used to communicate to our SAN via iSCSI?

    I don't know that I made the question properly, then do not hesitate to ask for more information or clarification.

    You want to disable HA on the cluster to blow course because if you don't switch redundancy to your ESX hosts you will have a failover of working capital.  It would be advisable to stop or pause the VM as ise this switch for iSCSI storage access, however I did some tests on this and if no vm run they freeze literally just in time and as soon as the storage returns they pick up where they left off.  I have to admit that I am impressed by the way the VM manages connectivity lose to their storage.  That said you should technically their power off or suspend them.

  • Resolution + - Does anyone have this from their laptop DVD?

    Anyone has the program resolution + in their laptop?

    I have the A660 announced with resolution + but this is not not in the laptop and I want to clarify this point with the other.

    That's what he's supposed to do:
    Using Toshiba's resolution + technology unique, images from standard-definition DVD image quality can be improved to a level close to HD, convert the 480 p signal on standard DVD video in 720 p or 1080i signals for optimal display on screens quality high definition. Thanks to Toshiba of technology resolution +, image quality is just great. Details of the contours is more clear and images look crisper, with enhanced images that friserait the quality high definition

    See:
    http://EU.computers.Toshiba-Europe.com/innovation/generic/easymedia_entertainment_eu/?feature=resolution+#resolution+

    Thank you

    What do you mean with resolution + program?
    AFAIK that is not program. This is the new technology used on new laptops from Toshiba and TV to increase the image quality and it is part of ENTERTAINMENT EASY

    On this technology, you can find lots of information on the pages of support Toshiba and also very interesting movies on YouTube.

  • vSphere Essentials, anyone using this bundle, thoughts?

    We have three servers free ESXi v4. I work on a project of various groups to try to get the money to buy the bundle of vSphere Essentials so that I can attach the 3 servers together under a single management console and get consolidated backup.

    Before I buy it I wanted to check here to get your opinion on this set. Was - this value of the passage of the free to the point, do you want you would have gone with a different bundle with more features?

    Thanks for all insite,

    Mike

    No, you're right. You would seek to 6 Standard licenses and 1 license of vCenter Foundation. There is no Acceleration Pack for Standard (big mistake IMHO).

    Essentials is a package very well. If ca foresee you being OK with 3 guests, for a reasonable amount of time and a date, will not want to use SRM, then go ahead.

  • Does anyone use the project manager?

    Hello

    I have printing that Manager project does not serve much. I use CS4.

    However, here is my attempt.

    I worked on a project for a friend, and as I was going out of town, he wanted to do a little

    editing on the project with his computer.  It also has the CS4.

    So, I used the project manager and made the following choices:

    1. I clicked on: "Collect files and copy them to the new location."

    2. I clicked on and chosen: "exclude the unused Clips.

    3. I clicked and selected: "Include preview files, 'Include audio conform files' and 'Multimedia files Remane to match clip names'."

    4. I made the destination of my office project.  He showed the 51 concert in the project.  Then I transferred all of my office to help connect an external hard drive with an eSADA.

    When my friend all this on drugs on his hard drive and opened his Pro CS4 the Prem, the project looked just like he did on my computer, with the exception: all the video clips were 'offline' of course, they were originally on one of my hard drives, but not "hard drive project.

    I expected the project manager to copy the files from all three of my drives with everything else.  In addition, some of the music was absent (offline).

    I expect too much from the project manager?  It will copy all files, audio, video, F / x all hard drives etc?

    I'd appreciate help here how to use the project manager and get everything.

    Thank you, Tom

    They are in offline mode because they aren't in the same place they were before - your office.

    Your friend will have to connect the media.

  • Does anyone use a headset/mic combo port?

    Hi, we are looking at 4310, which seems to have a single audio port, what he calls a headset/mic combo.

    I've not seen this before. Can someone explain how this works?

    Wouldn't not functional enough to support good quality VOIP?

    Thanks in advance for your comments

    That we can find so far, this combo port is similar to what you would find on a mobile device, like an itouch; Indeed, we use headphones earphones apple - where the microphone part of the cable - with her.  The voice quality is not very good compared to a stand-alone module microphone, but it seems to work.

  • Does anyone know how to make custom date formats?

    Hello

    In lightroom 4, I found a very useful tip where you can change the file that controls how the date format in the import of the dialogue work part - and more importantly it allows you to choose folder also locations, so when I import from another device that I can have the structure of folders as I like.

    The trouble is I know its there and it will be just a case of copy of the file that I was in the right place.

    If you want to know other things, watch no English versions of TranslatedStrings.txt

    For example:

    ' $$$ / locale_metric/Mac/Panel/maxWidth = 900.

    ' $$$ / locale_metric/Win/Panel/maxWidth = 900.

    ' $$$ / AgLibrary/Menu/picture/Label/Toggle5Shortcut = Ctrl + 9.

    «$$$ / AgDevelop/located/LuminanceNoiseReduction = Lum.» NR.

    PS - think of configurator from Lightroom (online Jeffrey Friedl) if mounting gobble - de-* as it is too for you - it provides a nice UI on the contrary - but I don't know if it covers all things or not.
