FC switch for xsan and xgrid!

Hi,
Can somebody suggest me any swithc which will work with Xsan and Xgrid (over mac pro 5.1 FC card - lsi7204ep) with 20 port, 8 port default active?
P.S.
One interesting thing is that on LSI home page this card (lsi7204ep) has no support to Mac OS, however it's lates that come with Mac Pro 5.1!

Go with the QLogic devices. I've had good success with their products from the 5200 on up. Some units have dual power (which saved my bacon). If your sales rep tries to sell you the enterprise management suite say no thanks. I've been able to do everything with the built in web management tool.

Fibre Switch for Xsan

We have an Xserve and an Xserve raid. We do not own a fibre switch. The xserve has a fibre card with two connections on it. The copper fibre goes out of the xserve and right into the raid. We own a copy of Xsan but are not presently running it. Here are my two questions. If we run Xsan, will I get better performance out of my connection to the raid as it will it be faster? And if I turn my raid into a san, do I have to have a fibre switch or can I hook the Xserver copper fibre right into the raid like I have it now> Sorry for the newbie questions, but I gotta figure this out somehow. Thanks

If you only have one RAID and only need it connected to that one server, you do not need a SAN. You will not see an increase in performance.

Question in switching for STP and loop

hi ,
i have a question in loop issue , will it occur in this case or not
i will describe my scenario as below :
now i have 4 switches connected with full mesh.
=================
3 of them has stp protocol enabled
only 1 of them is un manged and dont support STP protocol
====================================
the question is :
if i connected the 4 switches full mesh , will the loop occurs ??
as i believe , stp loop prevention depend on the switch itself not on their neighbour , but not sure from my understanding
wish to help

If there's only one or two non-STP switches, in a full mesh, you'll be okay. Once you have at least three non-STP switches, in a full mesh, you have a loop between them.

Which switch for POE and 7940G phones?

I have 2 (and maybe soon 5 more) 7940G phones to add to my network, which already has a Netgear POE capable switch. I've since discovered that early Cisco POE isn't the same thing as current POE, and the switch doesn't power the phones.
I was looking at adding a Cisco SD208P 8-port switch to power the phones, but I soon discovered it only has 4 POE ports, and I'm not sure that this switch will even power the 7940G phones. And if the other 5 phones show up, I'll need two of those switches with no room for expansion on the voice network.
Will this switch power those phones?
Is there another small switch available so I don't have to replace my existing switch infrastructure to get these phones to work? Or do I need to scrap the phones and get something newer that will work with the current POE standards?

Will,
I would look at the ESW520 8 port switch, it will power the phones and will have the "*" VLAN's already setup in them.
Side note "*": This assumes that you are using VLAN100 and Cisco Voice system for the switch
Have a great day

Different physical networks for public and private IPs ?

Hi,
My ISP router, public sides and private sides of my servers are all plugged on the same switch. I was wondering if the troubles I experience with my home directories server, hanging all services very often, can come from that config. Does it make sense to usse different switches for public and private IPs ?

It's a good practice to put external and internal traffic on different switches or, at least, on different VLANs on the switch to segregate the traffic.
However, it's unlikely to cause the problems you describe unless there's something wrong with the network (e.g. it's overloaded or experiencing some kind of broadcast storm.
If you have a separate switch it's worth trying. Without knowing the make and model of your switch it's impossible to tell whether VLANs are a viable option for you.

I am using Mail for emails and I seem to have two different windows that switch between the two. The emails are the same but the second window opens when I click on any details and I cannot see the top of my screen with control icons for internet, file

I am not very tech savy and apologize in advance if my question is not clear. I use the Mail application on my mac and I have two users on my computer, one for gmail and another for my work email. All email addresses appear in the mail application on one page. When I open my email and click on a message it often goes to the other user screen and cuts off the top of my screen which shows the bar for Chrome, file, edit, view, history etc....Still functional but very annoying. How do I choose a user screen and stop having it switch back and forth.
Thank you.

Time Capsule - Can it run as DHCP router, create a wireless network and plug into switch for wired network all at the same time?

I have a closet with Wired connections from all over the house terminating in it. I also have the internet modem and a switch in this closet. My old setup was a netgear in the closet creating a wireless network and also feeding the Ethernet ports all over the house. In my room, I had an Airport express (a month old) bridging the wifi to make the wifi network larger. The Express was hard wired from the wall and my mac mini was using it's wifi (printer was plugged into other ethernet port). Everything was working great.
Fast forward to last week. My Netgear died. So, I bought a time capsule. My plan was to move the Express to the closet and have it create the wifi network and also then run cat 5 cord from express to the switch to feed all the wired wall plugs. Reset it and set it up to create the wifi network as well as DCHP NAT. Wireless was running great on it. Then I plugged in the Cat 5 in the second Ethernet Port to the switch. Wifi stopped working and none of the computers would connect using wired connections either. They would see a 'network' but nothing would work. I would unplug the Cat 5 feeding the swtich and the wireless would start working again. Plug the Cat 5 back in and wireless would stop.
So I thought I would try the Time Capsule in the closet and see if I could get it to work. Pretty much the same thing, except at this point I figured out if I went in and told it NOT to create a wifi network the wired portion worked fine and all the wired computers in the house worked fine. Of course, then I didn't have Wifi.
I'm not clueless when it comes to networking, but I can NOT figure this out! Can either the Time Capsule or Express Create the wifi network AND also feed the data to the switch for all the wired computers?
To simplify this is what I want my end result to be. I prefer the Time Capsule to be the wireless connection extender, but if I have to have the Express do it, I'm fine with that.
1. Express in the closet creating the wifi network as well as feeding the data to the wired connections via my switch.
2. have the Time capsule in my room at the opposite end of the house plugged into the hard wired connection to extend the wrieless network as well as have wired connections such as my printer and my Mac Mini.
If I can get #1 to work, I don't think I'll have any problems with #2. Help!

I have an equally complex setup with a managed switch actually but I have never seen the TC have this kind of issue.
What I do notice is you have changed the TC from defaults.. you are using a non-default IP range.
I have run across issues like this where people move things from default.
I would like you to start over.. factory reset the TC. That will set it back to default router mode.
Do the min setup on the TC..
1. Change all names from what you were using. That includes the TC name and wireless name/s
Make them short, no spaces and pure alphanumeric because that is the correct way to network. Apple default names with spaces and apostrophes are fundamentally bad.
2. With just the TC plugged into the switch.. and a single computer connected by ethernet. Power cycle the whole network.. this allows the switch to clear all the old MAC address.
3. Test on the computer just ethernet. Turn the wireless off.
The computer must use dhcp and must get an ip from the TC.
It has to get the correct Router.. ie Gateway.. I wish apple could stick with proper network terminology.
And it must get same address or valid DNS server address/es.
If it fails.. please plug ethernet directly to the TC.. bypassing the switch.
You should get the standard IP addressing and internet connection.
If not please post the screenshot from the Mac of the network preferences showing the ethernet setup.
I need to see what address it does get. I need you to make sure the ethernet is the TOP of the list. So rearrange the order of network connection. With the airport off it should just go to the top of the list.
If it appears to be working .. but a browser cannot connect, open a terminal and ping an internet address.
Ping the actual gateway address the ISP gives you and ping the ISP dns address.

How to set up VLAN for DATA and VOIP on SRW248G4P switch?

Hi guys,
I am totally new and was given this task to complete. I really really need help.
We are using one network 192.168.1.0
Shared with data and voip.
CISCO C870, 5 switches LINKSYS SRW248G4P .
The email wrote:-
On the Linksys switch;
- create two different VLANs one for voice and one for data.
- put a firewall between the two VLANs (between voice and data) and only enable certain ports to flow to voice network (inbound tcp 8443 and ssh )
What should i do guys? I really need a dumb guide now.
I know its simple for you guys but i am not a smart IT fella. Whats the step by step?

If the switch is new or you have support on this, then you might try calling the support center. Here is a link:
https://www.myciscocommunity.com/community/smallbizsupport
On the right hand side you can find links to the support center.
Here is a link to the guide:
http://www.cisco.com/en/US/products/ps9967/prod_maintenance_guides_list.html
@ the bottom of this link you can find your switch model, you want the larger of the two. In this guide it shows you how to create a second vlan.
Will your router be the firewall between the two?
Kindest regards,
Andrew Lissitz

Photoshopversion for mac and windows when switching?

Hi,
I have used now the photoshop trial version for windows for windows for a while and would like to buy the full version. However I will switch to a mac in December or January and would really appreciate If I would be able to start out with photoshop already now on my windows pc so that I don't have to wait with purchasing photoshop until I have the mac.
If I buy a photoshop license, will I get a version for both platforms or how does it generally work if switching platforms? I am also using Lightroom 4 and when I bought this as box it came with both a mac and windows version but I noticed that for photoshop I have to choose in the store.
Would be nice if you could help me with this.
Thanks in advance and regards,
Tom

Lightroom is multi-platform. It is licensed for Mac and/or Windows and you can install it on both since you can activate it on up to 2 computers.
Traditionally licensed versions of Photoshop and other apps are single platform licenses: Mac only or Windows only but you also have up to 2 activations. Mac/Mac or Win/Win.
Creative Cloud versions of Adobe Suites and apps (e.g. Photoshop) are all multi-platform licenses: Mac and/or Windows - so you can activate them on Win/Win or Mac/Mac or Win/Mac. That may work best in your situation purely from a licensing perspective but you'll be locked in to a monthly fee.
You can cross-grade from Windows to Mac but that usually involves an upgrade at the same time (e.g. CS5.5 Windows to CS6 Mac). Check with Adobe Sales for further options.
