• What is the difference between the external SCSI cables and cables data acquisition

  Hi all, I would like to make a simple extension using an external SCSI cable and a NOR 184749/SH 6868. In other words, it would be: female HD68 bolt of the cable ends OR coupled to an external SCSI HD 68 male with a VHDCI 68 male cable. What are the differences between the external SCSI cables and cables as the (M) 6868EP of the CHS data acquisition. Other than the sex of the end of HD68 is usually on one. How is the posting hit buy using an external SCSI cable for an extension to tell a BNC-2090?

  Yes, I realize that NEITHER wants us to buy their cable, but in these economic times difficult, to do use all available resources, so I have to try,.

  Thank you

  Hello

  As long as you have compatible connectors, SCSI cables will work DAQ of basic functions.  They have the advantage of NO cables is that we can meet our DAQ hardware.  So, we can create pairs twisted differential pairs to HAVE, using the ground for shielding terminals and generally specialize the cable to minimize noise and crosstalk.  Because the SCSI cables are not specialized, you are likely to see the most noise and, if you go the sampling rates more Rapids, crosstalk.  If you are in a laboratory or factory with a good amount of noise EMF that your readings are not quite as clean, or if you have fluorescent lights you might see 60 Hz noise you might not see otherwise.

  If you want more details on the specifications of the SH68-68-EPM cable, I recommend these two articles.  The first example of the twisted pair and the principles of the SH cable shielding and the second gives the most precise specifications that you can compare with when looking for a SCSI cable.

• ADSL and cable

  My current broadband is Orange through BT copper wire.but in a few months, my wife wants to go with Virgin via cable. I'm looking for is a wireless router that can be used with adsl and cable, I don't want to buy a new router then find when I go to the cable, I have to change to one that works on the cable. I have my eye that will do the job on the WRT110. Thanks You.Longlegs

  GV-thanks, I didn't know it was the way the router is configured on adsl or cable, I thought it could have been different connections at the back of the router, but you answered my query. Thanks Again.Longlegs

• How to compare premises, iSCSI and storage NFS for VMware ESXi 5 with IO Analyzer?

  Hello

  I have 2 hosts ESXi 5.0 with a few virtual machines running. I would compare the IO throughput for my local storage, iSCSI and NFS vmware storage store. Can someone point me to the right direction? I read the documents and tutorials, but I'm not sure how to compare tests from these 3 options.

  I have a need to compare the following storage options.

  Local disk on the ESX host

  iSCSI on QNAP NAS device

  iSCSI on EMC e 3100

  NFS on QNAP NAS device

  NFS on EMC e 3100

  IOmeter seems to be good tool based on reading, but still not clear where to make changes to pass tests of storage to another.

  Thanks in advance,

  Sam

  If you use IO monitor, then you must simply vmotion the VMS to the data store for the device you want to test, and then run the test (and Records results).  Can vmotion for the following data store and repeat.

• Questions about iSCSI and subnets

  IM planning on a deployment of 8 ESX servers connected to an array of iSCSI on double dedicated switches.

  1. 2 cards on each ESX host network is dedicated to iSCSI and VMware dependent ontraffic.
  2. SAN iSCSI target consists of two controllers with 2 uplinks of iscsi on each controller (4 total)
  3. The manufacturer of SAN is suggesting setting up of their SAN ports in separate subnets for higher throughput
  • For the sake of simplicity lets say assign 10.10.100.1 24 ports SAN 1 & 3 and 10.10.200.1 24-port SAN 2 & 4
  • On the side of ESX, a single iSCSI VMKernel address will be 10.10.100.2 and the other will be 10.10.200.2.

  My questions:

  1. do I have to enable trunking VLAN on the side of the switch so that the initiator 10.10.100.2 ESX failover to the port of SAN 10.10.200.1 and vice versa, because they are not in the same subnet and therefore not in the same VLAN?
  2. If this is the case, will trunking VLAN also solve the problem if we were to buy an identical iSCSI SAN on the road and 2 subnets more setup for controllers, but still only have two cards on the ESX Server.
  3. I would assign the 2nd ESX Server in this config with the same IP addresses as the first, or I re them with differnet IPs (but obviously still in the same subnet as the storage arrays), for example ESX 1 is 10.10.100.2 and ESX 2 would be 10.10.100.3

  Any other associated iSCSI I get with VMware, simply not able to think through this particular obsticle and I don't have the equipment to test it yet. Doesn't help that it's late in my part of the world and my brain power is depleting fast!

  Thank you!

  I mean really isolated network. No routing between them.

  Is the software of multiple paths that can pass a path to another, and if you need one network to another.

  Note that the PowerVault will have an interface of a mosquito net and to one another for each processor.

• sVMotion between iscsi and fc?

  I would like to know if sVMotion worked between iscsi and fc storage.  Just by looking at the possibility of moving from FC to iscsi on the road and wanted to check, it is that we give a host at the same time we can use svmotion to get the virtual machine out of a store on a datastore iscsi and FC database.

  Ideally the VM perform during this process. Any witch hunt, it's if it was running?

  Storage VMotion does not care SAN type, I carried out all types of migration between FC, iSCSI and NFS myself.

  So don't worry about it. But beware this SVMotion create large extra i/o load, so run when it will not affect the services running.

• ISCSI and FC SAN VI 3.5

  Hello gurus!

  I have a VI 3.5 with FC SAN environment, but now we need more hard drive space. I think the use of ISCSI SAN, but some people says that it is not correct (unstable) to use ISCSI and FC SAN in the same environment.

  What do you think of this?

  Thank you!

  You can always have FC, ISCSI and NFS presented to the same ESX Server, it will not come into conflict each other as long as you do not present the same logic of FC and ISCSI each unit number.

• Time Capsule do not pick up address DHCP and cable modem...

  You just bought a Time Capsule and a couple of Airport Express. If none of these devices are connected together via Ethernet, they seem to have set themselves up, and all is well.

  That being said, I tried to create a mobile network instead of pure wi - fi and am studying various behaviors that are not as expected when I rear hub to the Internet Time Capsule, but need to isolate and go 1 bit at a time... (it works not as well as suggest Apple instructions on homelessness of installation)...

  If:

  1. configuration of the modem cable shows that DHCP is 'ON' and supplied address range 192.168.0.x by 192.168.0.y,.

  2 Cable modem wireless is disabled,

  3 Time Capsule Wan is connected to the cable modem, Ethernet

  4 Time Capsule is configured to request its address IP, DHCP

  5. Airport Express is in Bridge mode and have addresses such as 10.x.y.z (appears to be from a Time capsule).

  6. safe as Time Capsule is set to be as DHCP and NAT

  7. There is NO other device in this configuration connected by Ethernet except the cable Modem and the Time Capsule.

  So, why is the IP address of the time Capsule 76.181.45.xyz? (The address is NOT in the range of the DHCP as described in the #1; it is not supposed to be?) ....

  Whence this address?

  A friend says this address puts the "other side" Time Capsule of the cable Modem, directly on the Net?... (Shouldn't worry?) ....

  If none of these devices are connected together via Ethernet, they seem to have set themselves up, and all is well.

  It's because you didn't have the devices connected via Ethernet before you set up the. Given that the installation utility saw a wireless connection, it is assumed that this was the way that you want to connect devices on your network at all times... so he put it this way.

  If you had an established connection Ethernet before you ran the installer, then the utility would have detected this connection and set up the airport to "expand using Ethernet", does not extend to assistance of wireless.

  (it works not as well as suggest Apple instructions on homelessness of installation)...

  If all goes well, you don't talk about this document... Wi - Fi base stations: extend the reach of your network wireless by adding additional base stations Wi - Fi - Apple Suppo... .. Since the 'how' information in this article is at least 4 years late, bear little resemblance to the latest version of AirPort Utility and some of the information are simply not true.  This document if trash is what you... He'll probably do more harm than good with regard to the details of setting.  The article is OK for basic general information, however.

  6. safe as Time Capsule is set to be as DHCP and NAT

  It should not be if your modem is a modem/router "" or type 'bridge' of the device which is also DHCP and NAT services. The fact that you have disabled the wireless on the device confirms that it is both a modem AND a router. That being the case, then you have two devices that both struggling among themselves to try to control the same network... AND do you also have a network error called Double NAT... something you don't want.

  Probably the best at everything again and provide us with the number of brand and model of your "modem", that we can confirm what it is that you have, then the correctly configured time Capsule to work with this device. Once the time Capsule is set up correctly, it will be easy to put in place the other airports.

• I have 2nd gen and cable provider ATV...

  I have ATV 2nd generation and the cable operator with lots of channels such as hbo, nick, etc. How can I watch shows from these channels using my ATV thanks

  This is a basic form of the app to the app, content providers. It has very little to do with your cable provider.

  IE things like CBS App offer broadcasts, but HBO NOW, I do not think this offer.

  While some applications may require that you connect with your account of cable television, this does not mean options Live are available.

  Live, you have your cable subscription and their box. Apple Tv is usually for on-demand playback, and do not have all of them live Tv stream options of programming.

  Hello aalexandrebeta

  Ask if they take over the client property of modems and if so what is recommended also ensure that it is a coaxial cable connection they use.

• Details of the 536304-001 HP Power On / Off switch and cable LED Assembly for the Z400

  Can someone help me with the P5 front header pinout on the motherboard Z400 or on the HP 536304-001 power switch and LED to the Z400 Cable Assembly?   I'm getting to is a Z400 motherboard in a case of XW8000. I know that 536304-001 does not fit in the case of XW8000 but the XW8000 part equivalent seems to have mostly the same connections. double color led, led hard drive, power button / stop.   I can see an illustration that 536304-001 use 4 connections on the side to key of header and 2 on the other. Cable colors are red, green, black and 3 white. There are also other connections to the temperature thermistor that I would not intend to use (unless explicitly required for Z400 motherboard).

  Here's a panel header pinout before Z400 P5 motherboard:

  

  Find "missing" pin key 14 to steer this diagram properly.

  Pins 2 and 4 go to the power LED.  This LED is two-way, with green in a sense (normal) and Red (diagnosis failure) in the other.  If the LEDs back to back are installed between pins 2 and 4, on lights.  If green it does not illuminate during normal operation, move the pins to the pair of diodes.

  Pins at 15, 17 and 18 are chassis ID pins.  It's OK to let those pins unconnected.

  Pins 6 and 8 are the power button pins.  Connect a normally open push switch between pins 6 and 8.  Do not attach any tension or Chin-ups to this switch.

  RESET # may not work, but it is a prototye signal.  A switch push-button normally open between pin 7 and 6 (GND) could make it work.  It's OK to let those pins unconnected.

  Terminals 11 and 12 are the thermal diode in the panel cable Assembly before Z400.  The system starts without the thermal diode, but fans can operate at full speed all the time, or may oscillate in speed (several times to go from slow to high-speed and back).  This will make the system very noisy.

• Optical digital work on the DVD and cable, but NOT on Youtube, Amazon Prime or applications.

  Just bought XBR65x850C. hung out on TV to stereo receiver digital optical cable. Works very well for cable and DVD player, but NO sound when I try to watch any application like Youtube, Amazon Prime, etc.. If I change to 'Speakers TV', I hear. I have I something wrong, or is this a bug? Is there a ' cheat around "such as the use of the stereo headphone jack? Thanks for any info.

  After reviewing all possible problems and opportunities, I found that the problem has been resolved by going to audio; Advanced; and optical audio output digital changinig; "Max". This enabled audio on all applications. Thank you.

• Network connection wireless and cable - Internet access that allows on a computer that is connected to the network cable connection to a networked computer

  I have 3 desktop PCs. Machine A is Win 7, the B machine is XP, the C machine is XP.

  Machine A is connected to the router via cable and internet connection works. Machine B is wireless (the same router as a machine) and the internet connection works when I used that machine has b. Now I plugged in the machine C B machine with a crossover cable and wireless internet machine B does not work.

  I tried the IP and gateway addresses manually (since deleted). If I ping the computer A to B I get the answer to time to stop and even if I ping the B to A computer. However ping computer B to C and C to B work.

  I hope that I have omitted some important parameter, if anyone can point me in the right direction

  Hello

  If the bridge, the connection between C and B is the first to be configured with a static IP address that is on a different subnet * and then fill.

  Alternatively, you can use ICS, http://support.microsoft.com/kb/306126/en-us

  * On the subnet

  Classical IP looks like this (example), 192.168. 1 .x the first three groups are also called subnet, they identify specific network, x can be a number between 0 and 255 and it identifies each unique device on the network.

  An IP address of 192.168. 2 .x would be a subnet to another network.

  To assign a static IP address, see http://www.howtogeek.com/howto/19249/how-to-assign-a-static-ip-address-in-xp-vista-or-windows-7/
