SQL and Exchange on the same material - need help with storage!

Hi all!

I am definitely a newbie in the world of virtualization.  A colleague and I have spent hours scouring the Internet and reading white papers for answers and have been unable to find exactly what it takes.  So far, there has not been a lack of trying.  We are a very small company with 75 employees.  We have an Exchange Server and implement our first SQL Server and we want to virtualize both on hardware nine using the ESX 4.0 Essentials.  I don't know, probably not the best two apps to virtualize on a single piece of hardware, but we have about 12 people, using SQL server... at least for the foreseeable

the future.  I'll try to make this simple in my questioning:

(1.) what is the difference between a logical unit number, a PIN, a VMFS, a VM data store and how they relate to each other?  I know what means LUNS and VMFS and I know what a brooch is a hard drive, so no links to wikis on the definition of a LUN ;-).  Been there, done that.   These terms seem to be used very freely in all directions and it's confusing about how they relate to storage.

(2.) we have 6 146 GB SAS drives for storage on my HP ML350G6, the config that I want to work with is the following:

2 hard drives - RAID 1 - held Exchange OS, T-logs Exchange and SQL OS (possibly install VCenter Server on that as well in another virtual machine)
4 hard drives - RAID 10 - will hold the Exchange and SQL DB database.

Y at - it faults with this configuration?

(3.) if #2 above is OK, how you (and you should in our small store scenario) cover several RAID (spindle?) arrays with a virtual machine.  In other words, how to you create a virtual Exchange computer and upgrade the operating system on a RAID, newspapers on the same value but different partition RAID and the Pb on a completely different RAID set?

(4.) if #2 not OK, I should just create 2 simple VM Exchange, a for SQL and worry not separate newspapers/operating systems of databases on RAID berries?

I thank you very much in advance!  These forums are wonderful!

Confused in Cincinnati,

Thanks for your reply Wes!   I have a few questions for follow-up

make sure that I understand.

Therefore a unit logic simply number a "partition" carved on a storage space (if that)

storage is a single hard drive or a RAID array)?   And of course each hard

drive is a PIN, but when you take 3 discs and their RAID together.

they, in fact, become a PIN, especially when it comes

on reduncanc and no performance?

VMware "" still does not see the storage, particularly the way in which you install. ESX will simply see a drive, format it with VMFS, so you can create files of your virtual hard disk on top of that (.vmdks) and your virtual configuration (.vmx)

I'm not sure I understand the concern with VCenter Server?   It can not

be on the same box as ESX running a VM couple?   My opinion is that

VCenter Server would be just an another VM on this box?   Maybe I need to

Read more on the VCenter Server!

vCenter may work in esx, but it is preferable to have an another box, also don't forget that vcenter has its own SQL database and needs 3 + GB of ram. In your configuration, you can do better leaving vcenter out of the picture completely.

Thanks again!

More like this:

RAID 1 array: LUN1-> Datastore1-> ExchangeOS.vmdk, ExchangeLogs.vmdk, SQLOS.vmdk RAID 10 Array: LUN2-> Datastore2-> ExchangeDB.vmdk, SQLDB.vmdk

  • Two cameras, but only we work at the same time, need help

    I have exceeded the posts here, but not found answers to my type of problem.  I have two WVC54GCAs both have static IP on my local network addresses and I can see them both very well from there.

    I forwarded the port for one to 47624 and the other in 47625 in my router at home and in the configuration of the camera, I specified to use these other ports instead of the default port 80.  When I work and try to view them on the internet by their ip address and port # (e.g. http://22.22.22.222:47624), I get a time-out error, but I see one if I go to 22.22.22.222:80 port (even if the port that I specified in the configuration of the camera was another port).  I used dyndns open port testing tool (http://www.dyndns.com/support/tools/openport.html) that shows 47624 and 47625 are both open ok.

    I can connect to my router on the work 22.22.22.222:8080 and the router logs show the dyndns tool connected to the router via these ports after the test.  I was using a Netgear router and thought that might be the problem, so went out and I have a router Linksys wRT54G2 to see if it worked better, but have the same problem with the Netgear.  Here's the weird part, if I go into the router to work and change one of the cameras to pass to port 80 instead of the other port I would fix for it, I can see that the camera on port 80 despite the camera config always configured to use another port.  So when I remove the first camera port 80 in my router and change the other to port 80, I can see the other as good as this.  I have Comcast as my ISP and a Motorola SB5100 cable modem and can't understand why I'm able to raise over the internet using the spare port settings I specified.  I have spent a lot of time on this, I'd appreciate any help or other suggestions on how to make.

    As far as I know, all Comcast modems are just bridges... no firewall in them at all... The other possibility is that your IT Department at work blocking traffic... have you tried this in any other place outside your local network?

  • Replaced the hard drive, need help with drivers and utilities!

    Hello

    Yesterday, I replaced my old hard drive with a new WD, and I reinstalled Windows Vista.  Everything goes fine until I jumped in the utilities and drivers (Resource CD) supplied with the laptop.  I guess I thought that the CD all the work, would do to reinstall all the necessary drivers and utilities...  Now I'm stuck with a laptop computer that cannot connect to the internet, and the screen is too big.  I don't know there is more wrong with my laptop than meets the eye.  On the CD of drivers & utilities there the list of drivers and some of them have check marks, others do not.  I tried following some online course on which those who/what order to upload, but I don't even have some recommended drivers on the Dell.com site (specific to my Inpiron 1545 model)!  I know that I could download them immediately the site, but I don't even have wifi to do.

    In addition, I read the performance of a Dell Factory Image Restore and I tried it.  When I get the black screen with no option, I have to click on "Repair computer" but the option is not available either... I thought that maybe it would be an easy way to restore my laptop (readers and all) to the original settings.  Maybe the option is not there because my computer is practically empty, with nothing to restore? All I have on my laptop at the moment is Windows Vista 64 bits and drivers a couple that I don't know much.

    Bit of help and advice would be great.

  • Several uses for the final product, need help with Render & output parameters

    Aloha, this is my 1st time in this forum... posted this question in Premier Pro and has been mentioned here.

    I created an effect straight project. I want to make four 4 very specific uses.  Unfortunately, I don't know anything about these formats to be given options in AE - CS4.  One of the many 'rendering settings' and 'output module' settings 'make model '.  This seems the best option for me given my future use: 1) for the DVD; (2) for electronic mail; (3) for YouTube. (4) my web site.  I read and reread the rendering and export options in the manual of use-AE CS4 without success in understanding what each option should be used for.  I need help in the translation of pixelpicker-talk.

    Can someone help me about these accurate "rendering settings" and "output module" parameters listed in AE in the option "make and model"?

    Thanks a lot... come visit the watrer is warm and clear as always.

    KonaDon

    I understand - I think the article using After Effects is a very complete resource, explaining the various features and their purposes. But the real world is full of special cases that are very difficult to address in a manual. In addition, it is a moving target. Different best options today probably the best choice, next year.

    Let's see if we can help here:

    1-. DVD: on the technical side, it is always MPEG-2. A very specific taste of MPEG-2. But while After Effects will let you export a file of this type (choosing the MPEG - 2 DVD is predefined in the output Module), it is also true that most of the applications (such as Adobe Encore DVD) DVD authoring are very friendly in terms of letting you wear one (ideally, uncompressed) Quicktime or AVI (which in no way is compatible DVD) and do the encoding in MPEG-2 for you. So it is up to you: you can encode EI using the preset DVD MPEG-2, or you can use an application of coding specialized (such as Adobe Media Encoder in stand-alone mode) or simply let the DVD authoring application do the encoding for you. This should be very simple and in this case, you can simply render a Quicktime or AVI file without loss (there is a model of output Module called "Lossless" who will take care of everything. You can use the default value, the 'best' model to make settings in most cases).

    2-. E-mail: on the one hand, you need something that is really light and as good quality as possible. In the other, you want something universal compatibility, which can be read in all or almost all computers. H264 (advanced version of MPEG-4) format is really good in terms of efficiency, but its ' adoption is perhaps not as widespread yet. Flash Video (FLV) is really good in this regard. In this case, you could choose Adobe Flash Video (FLV) as the format in the output Module and then choose preset FLV 'Flash 8 web small' for this purpose.

    3 YouTube: it's not that simple. The ideal format for YouTube is not quite exist, they insist on the re-encoding each file that you download, even if your file is technically identical in every way to their versions. So what you want here is something that looks good and it isn't huge to download. This all spells 'H264', in my opinion. The details depend on the question of if your Composition is HD or SD, 4:3 or 16:9, etc. Strange as it may seem, the big "iPod" preset for the format H264 is a good starting point. You can customize it to increase the speed of transmission a little (maybe 2 or 2.5 Mbps, against 1.5 Mbps).

    4 website: even once, you need something that most people already have in their computers. Flash Video is an excellent choice, since about 98 percent of users have the Flash plugin. But in this case, you can have more great heights and flow rates, so you can use the "Flash 8 big' defined by default as a starting point. Once the Flash 10 plugin (which now supports the H264 in addition FLV) spreads in the future, you could standardize on H264 in a delivery format, with different settings for each type of destination.

    I hope this helps.

    My price range is around $100-$200 for processor and graphics together.

    I looked at cela processor and graphics card

    They will make a big difference and improvement than what I have at the moment?   If this isn't the case, then can you guys give me some suggestions on the choice of the better ones out there?

    Thank you!

    You have only a 300w ATX PSU (Power Supply Unit), then you will need to update if you plan to install a good graphics card.  Check the manufacturers minimum power required for the card you decide on getting.  As for the CPU, it does not require the upgrade - the graphics card is what causes your performance problems (in the games).  I would like to spend more money on a power supply and graphics card and leave the CPU alon (so far )

  • USBOTG and Charge at the same time on Stream 8

    To keep this thread as productive as possible and efficient for those who find it useful to:

    Unless you have under your eyes

    1. a schematic representation of the 8 Stream USB port (USB port and battery electric circuit etc.)

    2 source code for the firmware BIOS and kernel that controls the material

    Please DO NOT respond or say "is not possible".  In view of the above is true, you do not have enough information to say '' not possible. ''

    If no one replys with a solution, what he calls not possible by default.

    Also please do not answer to say ' I don't know how "or" but I know how to do anything else that ' is also not that useful.

    An update of the BIOS or other software update may be required by HP, Microsoft or both to offer this feature really intuitive and quite possible.

    And I hope that this thread can be an effort consolidated by all who have the 8 flow to make the necessary changes.  The majority of the other tablet PCs are capable of it.  It seems that only the 8 Stream and a few others have trouble with her.

    ~~~~

    I want the ability to use a simple, inexpensive cable and perhaps standard (with electronic active minimum inside) which allows me to host and to use one or more USB devices on the Stream via its USB port B microphone 8 while this cable can also be connected to a charger standard and charge 8 flow simultaneously.  This means that the cable has a minimum of three connectors.  One of the possible configurations are as follows (apart from the normal charging cable):

    1 cable Micro USB B Male - connect to the stream 8

    2 USB male A - connect to the AC charger (IE one that came with the 8 Stream)

    3. USB A female - one or several connectors to plug into the key of USB data, keyboard, mouse or even a hub.

    Connector # 2. above shall provide a power supply to recharge the 8 Stream via conn. #1 and the power supply for external USB devices via conn. #3 so that they are in use - all at the same time.

    A and if the same cable can act as a normal OTG no charger for when no external power supply is available.  This may necessitate a switch or an electrontics active inside.

    The last part of this goal is unimportant for various reasons.  I wish that HP, the manufacturer of 8 flow, to State in writing good mode necessary to do this, so that other manufacturers or even-it yourself can make maximum use of their tablet HP equipment.

    ~~~~

    The neat thing it will alow a person to do with their tablet, it is to work at home using the Tablet as a desktop PC by connecting a keyboard, mouse, perhaps external screen (with USB to the display adapter) and knit for a long time without time limit prescribed by the battery life because the charger provides energy to all involved.

    If there is only a single connector on the cable #3, then an additional node of coarse had to provide support for these multiple USB devices at the same time.  However, it would be better if there were several #3 connectors integrated in the cable itself.  This would be better as a suitable USB hub also requires its own power.  That an adapter is necessary if the whole thing were integrated into one.

    ~~~~

    I really want answers from anyone who has already accomplished USB OTG delivered with simultaneous load with flow 8. (independent of any published 'proper' way is also welcome)

    Today's date is 2015-01-16.  If in 2015-02-16 (one month), nobody has posted a solution and then starts to bug HP and Microsoft on it's us?

    ~~~~

    Technical training:

    I understand the possibility the tablet software and firmware must take a decision on the manner in which power flows on the power port USB microphone B pins.

    I know that with a proper design of the electronic circuit carring these signals of power inside the Tablet could be sensitive to what is connected and without risk to decide for himself what to do without needing to control software.  For example by testing/detecting periodically differential voltage or current management to see what sides of the connector can supply.

    But this is only one of the many "could bes".

    In addition, this can be no standard regarding the standard USB.  What seems to be actually the case with a lot of cables OTG + fresh, is that physical clues embedded in the cable or charger are used to signal to the Tablet what the situation is.  Then the signal of software/firmware of the Tablet, interprets what the situation is intelligently and responds by flipping the bits of correct hardware control to activate, or deactivate the power flow in the port and also control its direction in or out.

    I'm not familiar with the standard USB.  Maybe I could do more research, if I believed that HP followed with 8 Stream or even the standard covered this situation explicitly.

    But to a certain extent, it seems I'll have to invent something that should be intuitively just like it does with other tablets. Isn't it?  Maybe I'm overthinking, but I can't find any USB OTG + cables load that specify compatibility with 8 HP flow.

    In any case, I was familiar with both methods other use of tablets to send the highest mentioned signal to the hardware/firmware/software of the tablet to the idea that it's time to load / time of OTG or both.

    The first method is a 0 Ohm to 200 ohms short between pin USB A 2 and 3.  This is the bidirectional data differential lines D - and D + respectively.  In data mode, all the data passes back and forth on those lines.  When you load with a cable, it's the charger module that puts this short, not on the cable.  I measured the short on three different Chargers.  It is 0 Ohms on two of them, one of those who are the charger that came with the 8 HP flow.  The others 0 ohms was generic.  The third was for an apple iPad and it measured on 53KOhms.  It's probably not the resistance ohms 0-200, but probably it is impedance termination indicating that there is some intelligent serial port communication in the charger itself.  Leave it to Apple to be different.

    This method is somewhat questionable, as this signaling mode would prevent OTG + fee because it seems unlikely that you will be able to OTG when the data lines are shorted each and overloaded with such low impedance.  I could be wrong on this subject...

    The other method I have seen suggested to work with some tablets and phones other than the 8 stream is too short the USB microphone B pin 5 to Terminal 4 with 0 Ohms to 100 000 Ohms.

    USB B has 5 pins.  USB has only 4.  The extra pin on B moves the GND pin 4 pin 5 pin to and makes pin 4 PIN ID.

    If this signal applies to a drop in the ID pin (4) or in some cases, I saw that she proposed, he runs down with 0 Ohms.

    Dead shorting things always makes me nervous.  If ID is a simple normally high impedance high input, resistance could be used to make voltage well below the low or zero threshold while also preventing the risk of damage when cheat on him with a device that you do not have the diagram for.

    Yet, 100K is a bit high for a 'pull down' in most of the situations that I'm used to.  Even a 10K would be uncertain. A 1 K or 2 K seems reliable enough, but then things are weaker and in know more nowadays low...   All but a dead short but if possible.

    So, it seems possible that the device might be able to "indicate" by the specific value of the resistance, which can be found here.  In other words the resistance is not a pull down but in fact a signature analog ID, in which case the exact value will be crucial. So if this is the case, a guess is not going to work.

    Obviously in such a system as described above, a chip inside the Stream 8 should be responsible to support this information. I hope the 8 Stream has such a chip.

    Probably a register inside this chip would be at all times what the State of the pin ID is a binary number.  All that is needed is for the BIOS to the chip and the registry in it and read this number via the bus to determine what happens to the port. Finally, he would use that signals of info to send the order of material to the electrontics of power set the appropriate direction to take etc.  (and change the State of the icon on the screen of the rude)

    I don't know if the PIN ID method described is a standard USB or not either.

    Eventually, there may be a third way. But I do not suspect that it would be possible with a non-active external device. In any case too complicated for the novice DIY for sure.

    The device would need to act is a kind of extension of bus.  As an active hub.  But she would use the negotiation of data USB serial lines and in addition to reproduce one or more additional USB ports, intelligently inform the tablet to get with the program which is "now we're going to otg and recharge at the same time."

    This requires a smart external device with a processor Inside, no doubt.

    It seems to me that many other tablets have been able achieve avecjoint here the need for a smart external device and thus the flow must also be able to do.

    There is a device that claims to be able to work with the HP Jet 7 and 8 and provides same ethernet and USB and big DVI ports so loads the data stream.  But its expensive because it is active.  Se here:

    It's called a "Docking Station".

    A reference to a product that does exactly what I want (possibly without active electronic components) is here:

    http://AMZN.com/B00LTHBCNM

    It's by Kirin and it is a device of type squid with four USB ports.  Precisely, which is my goal.  But read in the comments stream 7 user indicated that he would not be OTG and load, not really clear if it worked as a hub USB OTG or not.  Another evaluator stated that she would not support even a single USB device much less fees of 8 Stream.  This device has a switch.

    I forgot to mention that some 'hackers' have claimed success with other tablets to deceive their devices by using a multi-step process to plug things in.  Usually in general they would get connected Tablet and load first, then they would return a switch or something remove some resistance or the signal was introduced by the first position of the switch. For some reason any Tablet would continue to require. Then the data lines would be free and they would plug in a usb key and it mounts correctly even if the tablet was always in charge.

    It's like the power circuit has a lock which does not allow it to return to the mode "power flow" as long as he still feels the power flows inward regardless of what software it is telling.  Full proposal here.

    These tips seem dubious to me.  Changes in the BIOS could change the way it works.  Also you can not be sure what actually happens if you do not have a schematic representation.  You could damage your tablet.  Many people will support icon in the operating system whether the Tablet is in charge.  But I'm sort of a low-risk guy and my policy is generally indicators of intereperet not to have meaning at all once a device is functioning in a non-standard setting.  Especially when it's something that I did not built and could not fix if I FRY.

    Hypothetical reasoning: tell me what data sensory discs really the State of the charging light screen?  This reflect the bit of hardware control programs actually feeding management and status on the port?  Or does it measure the direction of the flow of power, said in the section of the circuit battery monitoring?  Point - none of us have a schema because it's owner. To really be sure according to the smart electronic hardware, the port must be mode flow under advisement "of power. If it's in a "power flow out" mode and power will be delivered externally as well you wind upward with both power supplies the same power at the wheel nets.  In this case, the two opposing regulators attempting both to drive 5 V can have slightly different voltage calibrations.  That could lead to fighting between them, with more than 100% of their capacity.  For example if you try to regulate 4.95 real V and the other and other attempts to regulate 5.05 V.  Current then flows to the tune of 100 mV / a few milliohms in the cables linking the two.  This may be several amperes. (many)  In other words, like I said: you want the tablet to know that power is coming in don't go out and automatically hitting the internal switches needed for that to happen. Probably the icon should indicate this with precision, but in some wacky situation, he could not. There may be a chance that the icon could indicate the load and still be burning or focusing on some circuits of the tablet or the charger.

    Another thing, I could see that happening is if you play with these reported resistance types enough you might find a resistance value that winds up place the device in an intermittent condition.  In other words it keeps flipping back and forth quickly between OTG and fresh.  It can give the illusion that it works.  You can have marginal communication with your USB devices and battery could even load.  But will still be a lot of stress on the power circuit.

    It is difficult for me to risk a Tablet perfectly well if I don't know exactly what I'm doing.

    If a brave individual makes their own experimentation and verifies that it charges and OTGs and you tell the rest of us, you're a hero.

    Maybe one of you has a good knowledge on the USB standard to have more confidence in such an experience... like what the ID pin 4 REALLY supposed to work for example?

    That's what I know so far.  If you think you can help, thanks in advance, or if this helped you, then your quite welcome.
