NAS connection with Exadata on Network Port

Hi,
What I found on exadata and NAS.
Can I connect the database servers to external storage?
Yes, you may use the network ports on the database servers to connect to external storage via NFS or iSCSI. However, the Fibre Channel Over Ethernet (FCoE) protocol is not supported or allowed.
My question is : What would be impact on performance if we connect Exadata with NAS on network port as NFS?
Does any one using ? I want to have all backup on disk and from disk to tape kind of.
Thanks

If you can afford it look at using zfs over infiniband for the best bandwidth if you go for 73xx or 74xx models. You will also get dual controllers for full redundancy.
Oracle's benchmark backup figures of 7 tb an hour are based on this setup If you go for a standard or 10 gig nfs connection you will get considerably slower speeds.
Thanks

Trying to set up my brand new MacBook Pro and it does not connect with the wifi network I have selected for this purpose. Nothing wrong with the wifi as both my iPad and iPhone are happily connected. Suggestions for connecting to the wifi network accepted

Setting up my brand new MacBook Pro and it will not connect to the wifi network. Nothing wrong with the network which is happily working for my iPhone and iPad! Suggestions accepted for making this connection.

Fixing this is a two step process:
1) System preferences > WiFi/Airport ...
... check [√] Ask to join new networks
"Known networks will be joined automatically.
If no known networks are available, you will
be asked before joining a new network."
2) Remove unwanted networks from the list of "known" networks under
System preferences > WiFi/Airport > (Advanced) > | Airport/WiFi pane ...
Close the window and save changes. If no joy, do a restart to ensure you are playing under the new rules.

TS1398 Not very helpful as I still cannot connect with my Netgear network with my iPad.

I have tried all the suggestions. I cannot download the previous iOS and am sure that the update iOS 6 is the whole crux of the problem. I cannot download as I cannot connect with the network. Any suggestions? I am a novice and need detailed help!

Is your N network using 5 GHz only? The tech specs for the iPhone 4S lists that it can only connect to N networks at 2.4 GHz. The iPad 2 specs do not list that restriction.

Airport Extreme dropping connection with a Cisco 5 port Giga switch

I've connected a Cisco 5 port Giga switch SG100D-05 to one of the LAN ports of the Airport Extreme and for some reason the connection is being dropped or it fails to connect. Any idea of why this is happening and how can it be fixed?

If you have not already done so, you might want to do some basic troubleshooting to try to isolate the cause of the issue.
To do that, temporarily disconnect the switch and power it off. Connect a computer with an Ethernet port on it to the LAN port on AirPort Extreme and turn off the wireless on the computer.
Test to see you can get a good Internet connection this way.
If you can, then you know that the LAN port on the AirPort Extreme is functioning correctly and your troubleshooting efforts will need to focus on testing each port on the Cisco switch.
If you cannot get a good connection with the computer connected directly to the AirPort Extreme, try another Ethernet cable that you know is working to eliminate the possibility of a bad Ethernet cable, which is the culprit more often than you might think.
Please post back on the results of your testing.

Why do I lose network connection with my standalone networked printer and have to reinstall it

I have a Laser Jet MFP M1530 printer that loses connection with the network. All the computers on the network have to delete the old configuration of the printer and reinstall it prior to it working. The printer is in a standalone configuration. Everything else on the network continues to work.

The Laser Jet MFP M1530 is a commercial product. I suggest posting in the forum for HP Business Support for a better chance at finding a solution.
You may find the Laserjet board here.

Iphone 3 and 4 can't connect with wireless through air port

We purchased a new Time Capsule yesterday to replace one that stopped working. We have been able to get the Air Port/network working for our Mac Books and iPads, but cannot access the wireless network on our iPhones (a 3 and a 4). The wireless connection function on the phones show the network and shows a check mark next to the network, but does not switch to the wireless network from 3G. We tried to 'forget the network' and sign in again, making sure we are on the WPA2. Any other suggestions? Tami

I had this happen to me yesterday. I have a AirPort Extreme and my iPhone was unable to connect to the wireless network.
I tried everything from resetting the network settings on my iPhone, Hardbooting the iPhone, and even changing the wireless password on my Wireless network and restarting the AirPort Extreme. Nothing worked.
However here is my solution:
Hardware restart. I just unplugged the AE waited about 20 seconds and plugged it back in. When it came back up ...My iPhone was able to connect to the network.

IPhone 4 suddenly stopped connecting with home wireless network

Upon getting a new wifi router, initially my iPhone 4 connected. Last night I lost wifi conneciton on it and cannot get it back. Updated to IOS 7.1 to see if it would help. Nothing. Have reset network setings, gone into airplane mode and attempted hard restart. Have also reset modem. The phone worked on another wireless network and all other devices in our house are working fine. Does anyone have any insights/ had this problem before? House network is Bell Fibe.
The phone can see the wirless network but when we go to connect it infinetly spins.
Thanks!!

I have 2 ipod touch 3rd gen. Cannot connect to my wifi. One will connect with neighbor's unsecure network..neither connect with my secured network

I have 2 ipod touch 3rd generation. Cannot connect to my wifi. One will connect on and off to my neighbor's unsecure wifi but neither will connect to my secured wifi. All my wireless computers connect plus my Ipad connects. They did connect at one time but haven't used them for anything but audio books which connect through Itunes on my computer. It shows my secured network name. When I originally connected them it was another rather with other security but since then I have bought new equipment. My Ipad and my printers just automatically connect. I have put in the Ip information plus but still no luck.

Try :
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router
- Reset network settings: Settings>General>Reset>Reset Network Settings

If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

LCD becomes fuzzy after connects with T61p through VGA port

Hello,
I have a Dell E207WFP LCD which is previously connected to a Dell desktop through VGA. Today I connect it to my T61p through VGA using the same cable. I am able to setup the resolution as native resolution which is 1680*1050 @ 60Hz. However, I found that the screen is obviously fuzzy than connect to the desktop. The font is not sharp. I tried to adjust the cleartype font in Win7 and the bright and contrast in the LCD but nothing helps. I connect it back to the desktop and it works fine... Both computers run Win7. Could you please let me know what could be the possible reason? Thank you very much!
My T61p uses FX 570m video card.

This is hard to judge without a picture. It could just be a low-quality VGA port which is not a defect but an attribute or a nature of many laptop VGA ports.
Remember that the VGA is an analog-type video connector and some sort of blurriness is to be expected, especially at higher resolutions, this is because the GPU processes the image digitally as well as the LCD, but the VGA is analog so the image has to go through 2 conversions.
In conclusion: VGA is great for use in projectors and other devices with resolution no higher than 1280x1024. Above this resolution, defects are likely to appear.
For higher resolutions I'd suggest purchasing the Advanced Mini Dock which features the digital DVI port.

Apple Remote desktop connection with different internet network

I did purchase "Apple Remote Desktop"in mac app store, it works well in the same wifi's network but when i try to use different network, but i won't connect.
It said " Please make sure Screen Sharing in the System preference", but it won't works as well.
Please help
Mac OS: 10.9.1
Apple Remote Desktop: 3.7.1

The first thing I'd suggest is that you talk to your network support group and make sure that the necessary IP ports, primarly 3283 and 5900, are open between the two networks. If those are blocked, ARD can't connect.
Hope that helps.

Hi,
There might be a problem with your router. On your iPod, under Settings>Wi-fi, tap the blue arrow next to your network. What does the IP Address begin with?
Hope this helps!

Can't connect with SFTP and custom port

I administer a website that recently switched its connection from FTP to SFTP, using port 21001. I tried to edit the connection profile in Contribute CS4 to SFTP, but don't see where to add the custom port. (Advanced options are for Proxy servers). I tried to append the port number to the host name (:21001), but Contribute still won't connect. I am able to connect to the webserver with the new settings using an FTP program. What do I need to do to specify the custom port for the SFTP connection in Contribute?
Thanks,
Robert

Use Static Ip,,,subnet mask ,,,Default Gateway & DNS numbers from the router setup page(Go to Status page) ... On the router changethe MTU size to 1365 ...click save settings ... Uncheck block WAN request under security tab ... Click save settings ... See if it works ...

Airport Express connection with my wireless network

Hi
I have tried to install my Airport Express, which was okay, but doing so I had to disconnect my wireless network.
What I would like to do is to connect the airport express to the wireless network (Linksys-router). I tried to choose the "Join an existing wireless network" in the admin utility, but now I have lost contact with my airport express base station.
Please help me....

What I would like to do is to connect the airport express to the wireless network (Linksys-router).
What are you trying to do with the AirPort Express Base Station (AX)? Use it for streaming iTunes and/or share a USB printer, or extend your existing Linksys wireless network?

Dropping Connection with My Two Networked XP SP2 Machines, Windows Update Issue???

Sorry to interject a completely different problem here, but I have experienced the following.
Blame me for the newb I am, but here is what I did after repeatedly losing conn and thinking that my modem was burned up after 2 years of use:
1) Attempted to buy a new DSL modem on Easter Sunday...good luck...
2) Went back home after not finding said modem to find connection working again
3) Wife did not use her desktop for 10 days due medical procedure (no connection problems)
4) Wife gets better, uses her networked computer, I start losing connection again.
5) Not realizing step 4, I call ATT dsl and am told, maybe you need a new filter on your DSL line. DL speeds return to proper speeds, think I am fine.
6) Wife uses Outlook 18 hours later while I am on my networked machine, we both lose connection
7) After reconnecting all possible wires, realize maybe the problem is with the latest Windows Update Patch OR a router problem
8) Go to my trusty Best Buy contact at nearby store, named Jason, and ask Jason if he has heard anything like this in the last 6 weeks...He THANKED ME PROFUSELY as he and his brother were experiencing the SAME networking problem. Jason removed the past 7 windows update patches and that removed the problem for him.
He has since turned off Windows Updates. Jason said that a couple of the update patches could not be uninstalled, but the 7 or so that could be uninstalled did the trick and he has not had dropped connections since.
Anyone else experiencing this? I talked to a cable modem user/friend and he has been experiencing similar problems but the Microsoft utility with his router allows him to double click to re-establish a connection, unlike me who has to power everything down, count to sixty, and power up.
(I have not yet uninstalled the patches but wondering what others have seen)
Thanks for the posts peeps!
