• iSCSI and Fibre Channel on the Dell PowerVault MD3000 SAN shaerd with 2 physical servers

  Hi all

  I'm doing new virtualization technologies work in my office for assistance:

  2 x Dell PowerEDGE 2950 III each installed with iSCSI next accessing the SAN controller

  1 x Dell PowerVault MD3000 (10 x 300 GB 15 k rpm SAS)

  The

  VMWare ESXi is installed in an internal USB to load 4 x virtual machines which is

  under SOLARIS (using project, houses, SAMBA file server and)

  Source code repository and compile the source code of the project Build

  Server too.)

  5 x Windows Server 2003 which perform as Apache Tomcat application server.

  And

  I wonder if it has performance benefits in the application of the

  Shared SAN for these two physical server via iSCSI in contrast with

  Fiber Channel.

  I am aware that CF is faster and more expensive, but in this case, I won t run a VM with DB server on it.

  must

  I enter the path to have iSCSI or stick with the given FC

  the SAN runs on 15 k rpm SAS used by 2 ESXi server.

  Please let us know of a reflection regarding this configuration.

  Thank you

  Usually, you take NIC 1 gb connections available on your host and configure them as such.

  2 network cards go to the San, most of the time that it is actually two networks with different subnets.

  1 network card next LAN

  1 network card for the management

  We only use three network cards currently on our guests, 2 for San and the other for management and lan. We use two switches dedicated to dedicated networks dual iSCSI san. This allows to easily add additional hosts in the future.

  You get to decide a bit, but the double san network is pretty much a given. You can do all this of course with the VLANs as well. We use the switches unmanaged yet in our Organization.

  PS: Passing path recommended is to have completely isolated storage of the LAN network / network of the user.

• What are the benefits should the software Intel offers compared to Win zero configuration

  (Satellite M60, Intel 2200BG)
  A few months ago Intel released new software WLAN (a major problem for the security, etc.). Initially, there was a memory leak problem, but he was soon fixed. However, they always seem to be a resource hog: there is the CPU usage in the Task Manager on the cob of 10 to 20% every 5 seconds all the time, also WIFI turned off & off, overall performance is affected - this can be seen for example in the tests of hard drive.

  I noticed that in order to use windows to configure WLAN & then kill two switching processes (iFramework, S32EvMon (?)) eliminates this activity.
  Recently, new Intel drivers are offered by Toshiba also, so I'm about to reinstall them with the option "drivers only".

  Anyone know what are the benefits should the full Intel software offer compared to Windows zero configuration?
  As far as I know, monitor event S32 is supposed to improve coordination Intel WLAN and LAN, working together.

  The new package is about 50MB in size, while the former was 2MB.

  Hi Sammo

  You have already preinstalled new driver? The package is really about 50 MB and Intel PROSet utility.

  I can tell you that offers software Intel the same configuration options of Windows. Maybe Utility Intel PROSet is friendly and kind but designed WLAN Windows settings by using, you can exactly the same.

  If you have more info on the download package and installation please let us know.

• Helps the FS7610 PS Series SAN, 10Gb network design

  Hi, we have currently a square of infrastructure EqualLogic SAN and NAS (2 x PS6510E, FS7500), a stack of two PC8024F 10 GB switches, 2 envelopes chassis m1000e blade with the A1 being a set of switches 1 GB m6220 fabric (fabric A2 a battery of the same thing), the tissue being a pile of m8024k B1 10 GB passes, (fabric B2 a battery of the same thing) and a stack of PC6224 two 1 GB (top of the grid GigE) switches.

  We all have this connected to the 10 GB being its own private network 10.1.0.x SAN network and vlan, nice and isolated from all the rest.  The blades can access the iSCSI shares via their network cards of 10 GB which is all on this network 10.1.0.x.  The NIC 1 GB on the blades are on a public network, and the FS7500 of the customer ports are on this network too via the 6224, so NFS connections are established via the public network to 1 GB.

  We intend to invest in an additional PS Series array to the host to a backup site, for replication.  At the same time, we plan to buy a FS7610 to our main site to take advantage of our 10 GB infrastructure and move the FS7500 existing to our backup site, so we can replicate iSCSI and NAS container volumes.

  That's where we could use some help, because now many things have changed.  Now, the SAN must be on the public network for replication to succeed, AND to take advantage of the connectivity of 10 GB and sharing NFS mount of the FS7610 through 10 Gbit, we need to use network cards 10 Gbit and switches in the network of the client NAS, that are already used for iSCSI traffic (and will in the future be used for connections to SAN vmware hypervisor).  In the FS7610 install and set up the guide, it says

  • Use the switches for network client and for the internal network and the SAN.
  • Use separate subnets for network client and for the internal network and the SAN.

  We can move the SAN and it is a dedicated subnet network and VLAN that is on the public network without problem, but my main concern is to be able to satisfy the recommendations/network configurations required for the FS7610 and avoid the local SAN/NAS traffic through a router to ensure connections of 10 GB.  Advice or tips are appreciated!

  It is the same thing that you are dealing with Linux, but TCP/IP standard routing.   You cannot route private subnets directly on the internet.  We need to create a "Wan".   Do not directly routed on the internet.

  Your WAN will create a private network and a tunnel over the Internet.   OpenVPN is a possible solution.

  A very widespread scenario might be:

  Once you have put WAN in place, on the internet of these routers would be a true internet address (e.g., 62.x.x.x.x) so the two WAN devices can communicate with each other.   They create a VPN tunnel with a new subnet, say 10.3.0.x.

  The WAN router primary side would have a leg on the subnet 10.1.0.x, say with 10.1.0.10 IP address as your default route on the side of EQL SAN 10.1.0.10.

  On the side of the DR this router would have a leg on the 10.2.0.x subnet, say 10.2.0.10.  The default GW on the side DR would be 10.2.0.10.   The router knows how to move packets between networks using the standard range.

  Looks like all you're missing is the "WAN" VPN tunnel between sites.  You want something that will encrypt traffic between the sites anyway.

  Who help me?

  Kind regards

• ESXi 5.5 nic teaming/LAG with trunking does not but it works on ESX 4.0.  Both are on the same switch. What gives?

  I have two hosts (vhost1 = ESX 4.0, vhost2 = 5.5 ESX) both are configured for the Group and both connected to a switch of 1544 Adtran L3 (named sw01).  vhost1 has been in production for several years with the config below and has been solid as a rock.  I'm trying to reproduce the installation of grouping/collage on vhost2 and it does not work when are associated but will work when you are using a single NIC (with or without aggregation).

  To be more specific about what does not work, two virtual servers have "Network server" (vlan 8) defined as a group of ports. Both physical and virtual servers on the same vlan cannot ping or resolve queries arp for virtual machines on vhost2.    Everything that is sent from a different subnet can connect to the virtual machines on each virtual server.

  So the question is this: why not ESX 5.5 works as ESX 4.0 when the configs are also near identical, as I can make them and they are connected to the same switch?

  Thanks for any input you can provide!

  Hello

  Do you share the vmnic for ESXi management and network of the VM?

  Try to follow the steps in this KB: VMware KB: NICs using EtherChannel grouping allows intermittent network connectivity in ESXi

  Trying to team adapters using EtherChannel, network connectivity is disrupted on an ESXi host. This problem occurs because grouping NIC properties will not propagate to the network management portgroup in ESXi.

  When you configure the ESXi host for grouping of NETWORK cards in attributing to the road based on ip hashload balancing, this configuration is not propagated to the portgroup management network.

  Workaround

  Note: to reduce the possibility network loss please change the route based on the hash of IP using this method of balancing load vSwitch

  1. Close all ports in the physical switch team leaving a single port as active.
  2. Change the Route based on ip hash vSwitch and load balancing management Portgroup.
  3. Set up the physical switch port channel.
  4. Activate the physical switch ports.

  Notes: Using this method will avoid a loss of connection when you switch to a port channel. Also make sure that under the properties for vmk portgroup # used for network management you tick the box "Enabled".

• Aggregation of links ESXi requires the configuration of the physical switch?

  Hello

  I have two physical servers that I'll put up with ESXi. Each server has eight physical network cards. My plan is on each server to use:
  -2 management - connected to vSwitch0
  -2 for VMotion - connected to vSwitch1
  -2 for iSCSI - connected to vSwitch2 (I'll use a SAN)
  -2 to access VM network - connected to vSwitch3

  For each pair, a cable should be connected to switch1 and the second would be plugged into switch2.

  The switches are HP A5120 which are stacked into a big switch with RFID. for example I have a 'big' switch which, if one of the two physical switches dies or is turned off, would cause the 'great' switch to lose half of its ports. In this way, all four networks are expected to continue to operate even if a switch "dies."

  All the information I found online said that ESXi can have two physical cards attached to a unique vSwitch and can then do things smart for redundancy (in which case a physical NETWORK card dies) and load balanacing.

  However, while all the guides tell me how to configure it on ESXi, I'm still not sure if I should combine the two cables on the physical switches.

  So, my questions are:

  (1) in order to get the NIC or balancing working in ESXi, redundancy do I have to combine two physical ports that will connect connect two physical ports that connect to the vSwitch?

  (2) with the consolidation of NETWORK cards, I see how to have an active adapter for the management network, and an auxiliary card works fine, but for the iSCSI network, I wouldn't have only two active adapters for double the bandwidth?

  Any ideas would be much appreciated.

  Thank you.

  (1) in order to get the NIC or balancing working in ESXi, redundancy do I have to combine two physical ports that will connect connect two physical ports that connect to the vSwitch?

  No, there is no need to configure etherchannel/LACP but this will depend on the type of load balancing, you click on the ESXi host - if you use by default, you don't need to configure Etehrchannel/LACP since traffic for each virtual network interface will be only com ove a single physical port, but you will always have the reiciliency to the case where if one of the physical NIC fails traffic then released the remaining port

  If you select the hash of the IP load balancing, you must then implement Etherchannel/LACP on your physical switch since traffice can come form any physical port in the team.

  (2) with the consolidation of NETWORK cards, I see how to have an active adapter for the management network, and an auxiliary card works fine, but for the iSCSI network, I wouldn't have only two active adapters for double the bandwidth?

  Onece well once again it will depend on the Load Balancing method, you select, but you will never be able to create links physical ports to get all of the 2 GB =

• How to ENTER ON the new tab page? Can't seem to make this work. The toggle switch is missing.

  The switch to the new tab page is not there in the upper right. Where is he?

  If browser.newtab.url has been "grayed out" subject: config it's probably because it's already the default value, which is of about: newtab... so you don't need to reset. Since you have to reset the preference browser.newtabpage.enabled (to true, by default) then the "toggle switch" should appear, as shown here:

  • https://support.Mozilla.org/en-us/KB/new-tab-page-show-hide-and-customize-top-sites

  If browser.newtabpage.enabled is now fixed to true and that you still don't see the "switch", you can try Search reset the module that will restore the parameter browser.newtab.url (as well as other preferences related to research and the homepage) to the default value.

  Hello

  Are you sure that the problem is the lid switch? Normally if the backlight doesn t work on the screen inverter FL needs to be replaced.
  What happens if you connect an external monitor to the laptop? You see an image?

  The FL switch is normally placed under the cover of the display. It s a little trickier to Exchange because it is necessary to remove the plastic cover of the screen.
  Maybe you should ask a technician for laptop to help.

• Tecra S11 - bluescreen when the WiFi switch is on

  I've known several accidents suddenly blue screen, with apparently no advice. After several tests of different conditions I counted it takes place when the WiFi switch is on. So, it should be associated with Bluetooth or WiFi.

  Any suggestions how to proceed further? apparently I have the latest drivers (Windows 7 64)
  Thanks, Guido

  Hey Buddy,

  Have you already checked the BIOS if you have installed the latest version? If this is not the case check this on the Web from Toshiba site and make an update of the BIOS. Maybe it helps

  But I had a similar problem last year and the solution was exchanging the WLAN card.

  I think your Tecra S11 should still be under warranty and in this case that the repair will be free. :)

  I lost my iPhone 5 and the "Cell" switch is off. How can I turn back on from another phone so I can activate "Find my phone"?

  You can not. There is no method to remote turn on/off all the settings on the phone. The only thing you can do is put it in mode lost through the computer and it remains to be seen if the device connects to a known Wi - Fi network. Otherwise, you'll just go out and pick up the old-fashioned way. You have it in Mode plane, or you just disable cellular data?

  Hello

  I guess the 6 LED's LED wireless card.

  This LED should shine when you activate the WLan switch on the side of the laptop.
  Looks like you have not activated the WLan switch.
  I put t know exactly where the WLan switch, but you should check the front of the laptop near the headphone jack.

  Check it out.
  Then the LED should shine and you must activate the antenna with the FN + F8 key combination.
