What switch do you recommend

Hello

Brief description of our environment...

x 1 poweredge R720 with x 4 network ports for iSCSI
x 2 poweregde R710 with x 4 network ports for iSCSI
x 1 poweregde R610 with x 2 network ports for iSCSI

x 2 PS6100E EQL
x 2 PS4100E EQL
x 2 PS6000 EQL
X 4 PS5000 EQL

Everything is distributed evenly between two floors of the building by using SyncRep and regular replication on the EQL boxes and using a VMware HA and DRS cluster on hosts.
Physically separate networks for iSCSI network and production.

We use 5448 powerconnect on the iSCSI network switches. One PC5448 for each floor and they are connected with x 4 fiber LACP trunk link.

I know that these switches have to be replaced, but what? PC6248, PC7048 or Force10? Perhaps even another manufacturer? If so which model? The price IS a decisive factor, I don't have the budget for expensive stuff

Check the support matrix Equallogic to get an idea of what switches are validated and supported / recommended. It is not limited only the Dell switches (Cisco, Juniper and Brocade options listed there).

First, you'll want to upgrade to double switches on each floor and LACP together. You can stack them, but this has the drawback that if ever you want to / need to upgrade the firmware of the switch in one or both of the rooms, you'll need 100% service interruptions in this room.

In my next part I'll stick to switches Dell since it is a Dell message board.

I would skip the PC6200 series unless your budget can not install a switch better. The 6200 is a decent switch, but it's on its way out (this can be seen by the fact that Dell has not updated the firmware on the switch since the 3.3 series (all 7 k and higher switches are now on a firmware 5.x).) The Force10 S25 series is better than this PC7024 a switch, but if you plan to switch to 10 GB at some point, you may consider a pair of 8132 s PowerConnect in each room. The non - F version uses RJ45 ports that can make 1Gbit and 10 GB, then you can use to start just the current units of EQL, but new units could be 10Gbit units. You want to get the QSFP + optional modules for each switch and 2 wires for each pair, so you can use these 2 40Gbit LACP ports switches set in each room.

If you want to use a LACP between the 2 rooms consisting of two switches, you have a more difficult choice to make; stack the switches (with the disadvantage that I mentioned above), or upgrade to Force10 S4820s that these offer the possibility to make a channel of port on 2 non-Stack switches (PowerConnect firmware does not offer this).

Cisco and Brocade offer similar characteristics (to execute a LACP on 2 switches non-Stack), but I do not know what exact firmware and/or switches that would offer.

  • What font would you recommend for a University newspaper?

    I created a new design for my University newspaper. What font do you recommend, and what style exactly?

    I would be happy to know your opinion and maybe even some still useful advice, since this is the first time I'm designing of a newspaper (I use InDesign CS3)

    Thank you

    Tom

    But seriously. For a newspaper, I would avoid without font ("Arial", Helvetica, universe, myriad). Why not try some of the rich classics? A few of them come on the InDesign DVD, but I don't know which. Minion Pro is a very nice, but perhaps too modern. Try Jenson Pro, Caslon Pro or Adobe Garamond Pro. The 'Pro' means that these fonts have extended features, such as the former graphic ornaments (very pretty when used in the proper context!), style old numbering and true small capitals.

    Use a classic police will be your journal gives a very high class look. For a large page, you can use columns of three (or four); even on a smaller size of the page, two columns look better than one. It also gives you the advantage of having guidelines for one, one-and-a-half, two or even three images wide column and headlines. Try to go to a fully justified text; tinkering with hyphenation settings until it looks right (I think that default ID parameters are okay for the fairly narrow columns). Use a lot of spacing; This guy don't like being cramped.

    Use small caps to the recurring titles such as "CALENDAR"; 'FORUM '. 'LETTERS '. "EDITORIAL". Good headlines, you have the choice of what whether normal type (in a really huge size) bold or italic. Focus on columns for that look of the 18th century

    Whatever you do, don't run amok with different fonts! Use a font exclusively for texts 'main '; Use it in a smaller size for the "lesser" texts, such as the photo captions, tables or 'notes '. Don't let someone tell you about in screaming headlines! ; Once you decide on a design, stick and defend when necessary.

    Hello marketsource,.

    For later use, please do not share your serial number on the forums where this was considered personal information (that is why it is x'ed in blue). What to recommend a good processor, I need to know what kind of motherboard you have. Go to support.lenovo.com, enter your machine type (B520), go to the product detail, detail parts, spare parts system, and from there, you will need to enter your country and your serial number. It will give you a list of your system configuration. Go where is the mother card/system board and type the model number of your board here. I'll look in the list of compatible processors for her. Hope that helps.

  • What App would you recommend to run virtual machines on an Imac?

    I would try to have virtual machines running on my IMac, but I'm having a hard time finding any material on this topic from apple.

    Ideally, I would like to my main x os to start and then simply turn a small virtual machines or containers from OSX.

    Any recommendations? or articles about the support of Apple for such a thing?

    There are three choices:

    Parallels Desktop for Mac

    VM fusion

    VirtualBox

    The first two are commercial products. The third is a free, open source. Three Parallels is the best.

  • I need to destroy the data on my laptop (before I sell it). What software do you recommend?

    I use windows XP.

    If you have installation of an operating system media or are willing to sell your computer without an operating system (if you can), then download Darik Boot and Nuke, that securely erases the entire drive, including any hidden restore partition.

    If you want to delete some files in a selective way and save the lives of others - a pretty risky choice if you are concerned about your personal information - you need to one of various utilities 'Crusher' who claim to be able to do.  Don't forget that you need to "grind" "unused" space this is in addition to the specific files that select you for deletion.

    See http://www.google.com/search?btnG=1&pws=0&q=file+shredder I have not used any of these tools. Read reviews of the software on the download sites; some of the apps seem to break some Windows features when they shred the (not terribly surprising) data.

  • I am currently using three different computers for Photoshop only. What plan would you recommend for this type of work?

    Can someone help me pick the plan?

    You will need the subscriptions as the number of machines that you use at the same time.  For Photoshop, you're probably better off getting the plan of photography since it is half of the price of getting Photoshoip like a plan unique app.

    Kind regards

    In this case, I start with the Plan of Photography Photoshop offers Photoshop and Lightroom for $10 per month.  Then switch to a full CC subscription when you can afford it.  Photoshop will do OK vector graphics and high quality PDF print to send output to the printer.  When it is really not very good, for multi-page documents, InDesign is King for this application, but you might be able to find MS Publisher on an old desktop DVD.

  • I just uploaded a clip of mpeg streams but tells me I can't use it without a mpeg-2 Playback component.  Can you recommend what to buy?

    I just uploaded a clip of mpeg streams but tells me I can't use it without a mpeg-2 Playback component.  Can you recommend what to buy?

    You can use Streamclip for most cases, but to play MPEG-2 files, like. VOB files, and to convert them to other formats, you should buy the reading component QuickTime MPEG-2 for Mac OSX, you can get online from the Apple Store for $19.99.

    However, I am under El Capitan like you, and when I tried to install the MPEG-2 component, I got a message that it could not be installed on my

    disk because the app was for an earlier version of my OS.  I don't know if others have had this problem, but I thought that I could

    mention it to you before you passed the $20.00.
