VSAN guests can access the FC SAN storage at the same time?
Soon we will invest in new ESXi hosts and we want to design them for the ability to VSAN. But since VSAN is a fairly new technology, we also want the same hosts to act as our old guests and have warehouses of data in our SAN (FC SAN attached storage) environment.
Host VSANS have access to VSAN and FC SAN storage at the same time?
What advantages and disadvantages do you see with this design?
Yes, there is nothing to stop an ESXi participating both host a cluster VSAN, and also had access other storage taken in charge of protocols such as NFS, FC, FCoE or iSCSI.
However, you will not be able to use the LUNS or Volumes presented on NFS, FC, FCoE or iSCSI for storage VSAN.
VSAN requires local disks to build the VSAN data store.
I guess the only concern would be the additional management that comes with having many types of different storage, but this is true even if VSAN wasn't in the picture.

Cannot open 2 Virtual Machines at the same time to access the same database
People,
Hello.
I'm installing RAC Oracle Database 11 g 2 system with 2 Virtual Machines (rac1 and rac2) on top 3 VMPlayer.
The VM rac1 and rac2 when one of them is stopped.
Their locations are F:\VM_RAC\rac1 and F:\VM_RAC\rac2.
I opened rac1 rac2 is running. But this error message appears:
Error: "cannot open F:\VM_RAC\sharerac\asm1.vmdk drive or one instant records, that depends. Reason: cannot lock the file. »
While rac1 running, I opened rac2. But this error message appears:
Error: "cannot open F:\VM_RAC\sharerac\asm1.vmdk drive or one instant records, that depends. Reason: cannot lock the file. »
2 error messages are the same. This means that I can not open 2and rac1 rac2 VMs at the same time. When we run RAC system, must open 2 "machines" or machines to more than 2 at the same time, so that all machines can access the same database server.
My question is:
Can all folk tell me how have rac1 and rac2 run at the same time?
Thank you.Unfortunately no, Oracle RAC requires that all nodes can visit the same set of shared disks. If your database resides within the DSO, each instance ASM (one per node) must also see the same set of disks to ASM diskgroup containing the data of the database files.
Best regards

I want home pages Firefox 3 separate and distinct for each of my 3 accounts to be open at the same time.
Questions are usually followed by a question mark. My reply has answered your question.
Firefox does not have an email, there is no "accounts of Firefox. If you access "electronic mail" with Firefox, you can use web mail. Some web mail services do not allow direct access, they want their users to access their mail from a "portal" or "Home" and will redirect any attempt to load a web site page "internal" return to home page.
In measure 3 loading different web e-mail accounts at the same time, if they are in the same domain it does not work on Firefox without an addon of Firefox. http://Br.mozdev.org/Multifox/
IOW, if these three E-mail accounts with Yahoo, without this add-on you would have to connect separately for each e-mail account, log out of the first before logging in the 2nd. Then disconnect the 2nd before logging in the 3rd. Firefox is not able to have several session cookies for a simultaneous connection to the same server. This add-on provides this feature of "multiple sessions cookies".

I can't access the same website on my MacBook I can on my IPad. I get a cannot locate the site on the computer, but I can see it on the iPad. Both use Google as a home page and Safari as a browser.
A single site?
What site?
Maybe:
If Safari is slow, unresponsive, which closes unexpectedly, or has other issues - Apple Support
Which version of OSX? If it is 'Mac OS X (10.5.5),' as you say it is because the version of Safari is too old

I can not access my Verizon email on my iPad. I can access the login page, but there is no box to enter the user name. I talked to Verizon support, and they say no problem at their end. Any ideas?
Macbeth,
From your description, it appears you are trying to get your mail using Safari to access your e-mail account. Why you do not use the Mail App?

A few days ago Firefox has stopped working when you use the shortcut or exe. file. The message http://en-gb.start3.mozilla.com/firefox?client=firefox-a & rls = org.mozilla: en - GB:official appears, even if when I paste this address in internet explore it works. What is preventing firefox to connect?
One possible cause is security software (firewall) that blocks or limits Firefox without you informing on this subject, possibly after the detection of changes (update) for the Firefox program.
Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox.
See Server not found - the problems of connection and Configure the firewall so that Firefox can access the Internet and http://kb.mozillazine.org/Firewalls

Since the installation of the latest update on my iPad, I'm unable to type a new address in the address bar of Safari. I can access the Web sites of my favorites, but when I press the address bar Safari closes its doors.
I reset holding home and power button at the same time. I did that 4 times. I also left all the settings.
I am also unable to access the server from imessage. I don't know if these two things are related, but the two that happened after the update to iOS 9.2.1
Since this announcement, I found a Reddit thread that suggests a temporary solution by disabling Safari suggestions. It worked for me.

I can using Ping IP or name of the computer for every user of AD.

Can someone tell me how I can access the internet on my laptop to someone else's House?
I want to take my computer on a visit, I can access the internet at home someone else with their supplier?
Hi Huw,
If it is a WIFI connection and they provide the access codes and Setup appropriate (and maybe even if they are not depending on how they are configured), it should be no problem. You will probably need to create a new connection to connect to their network and possibly another new connection to connect to internet (if they are separated). I created portable work of my wife to work from home in less than 5 minutes.
If you need to connect with a cable, then you need a cable and they need a way to connect to their network or their internet connection or even a computer connected to the internet connection can be used by ICS to give you access (even once, after you have setup the proper connections and codes installation).
The following may or may not be of help (although designed for Vista, you can get the general idea on their part and XP and W7will be similar and you should be able to work out the differences - if not, look how configure wireless internet access in "The BONES" of aid):
Here is a tutorial on how to set up a home network (including a wireless)-click on additional links for more information that may be helpful: http://windows.microsoft.com/en-US/windows-vista/Setting-up-a-home-network.
Here is an article on troubleshooting network connections wireless (with links): http://windows.microsoft.com/en-US/windows-vista/Troubleshoot-network-connection-problems.
Here's a long guide on wireless internet connections in Vista: http://www.techwarelabs.com/guides/misc_mod/vistaconnection/.
Here is an article on how to set up wireless internet in Vista: http://www.clpgh.org/usingthelibrary/technology/wireless/WindowsVista.pdf
The truth is it is relatively easy and is done all the time by many people. Think about all the people with laptops who take their origin and work at the same time and maybe even at Starbucks.
I hope this helps.
Good luck!

Here's my situation:
I bought 6 home edition of Windows XPthen freshly installed, they upgraded to Service Pack 3 and they activated via internetI have some shared folders in one of them, acts as a database for the other 5 ServerThe other (5 PCs) Access database files (Visual FoxPro) using (X & Y) mapped network driveI have no problem connecting until the last one (FP5)Windows XP of the 5th PC (client) said:"Year error occurred while reconnecting X: to \\Raya\WS-01\Server Palen.Microsoft Windows network: No more connections are possible to this remote computerat this time because there are already as many connections as the computer can acceptThe connection has not been restored. "What & why is it?Is a design limitation of Windows XP HOME edition which can only inter connect up to 5 PCs at the same time?Please advise, what is happening here?Thanks in advanceWindows XP Home Edition allows a maximum of 5 simultaneous incoming connections. XP Pro allowed 10.
The following note is from the Article KB 314882:
Note For Windows XP Professional, the maximum number of other computers that are permitted to simultaneously connect over the network is ten. This limit includes all transport and combined resources sharing protocols. For Windows XP Home Edition, the maximum number of other computers that are permitted to simultaneously connect over the network is five. This limit is the number of sessions simultaneously on other computers, that the system is permitted to accommodate. This limit does not apply to the use of administrative tools that attach from a remote computer.
