Any advantages to using a VPN accell card?

are the accellerator cards worth purchasing?  other than offloading the IPSEC onto the card from the maincpu is there any netwrok speed benefits i would see from using them on our devices? 
i'm thinking of getting a vac plus card for my pix 515.  i already have a card in the remote 2821 that came with the router.  (abeit old, AIM-VPN/EP)

  • Any advantages to using .mac vs. AIM account?

    I have both a .mac account and an AIM account. Currently I use my AIM account almost exclusively for iChat, and I was just wondering if there are any advantages to using my .mac over the free AIM.
    Also if friends of mine wanted to add my .mac name to their AIM what information would I give them? just [email protected]?

    hi Sup909,
    Encryption. Mac to Mac with both having @mac names
    Otherwise, No.

    Is there any advantage to use database helper class ( e.g. database.bookDB in Duke's bookstore)in servlet design? What if I setup a DB connection for every servlet?

    If there is not much relation between servlets.For example one servlet working on authentication againist user name/password in database another one work on searching book by keywords?
    and if we want to have servlets written by difference programmers?

  • Are there any advantages of using Secure Empty Trash over regular Empty Trash?

    Are there any advantages of using Secure Empty Trash over regular Empty Trash?

    If you are going to run around with sensitive files on your file system, you might be better off using a whole disk encryption so that every file is encrypted, any deleted file contains encrypted contents.  As long a no one can access your files using your encrytpion keys, all your data is secure.
    Also secure delete is not really going to do much on a Solid State Drive, and again whole disk encryption would be a better choice.
    For a moderate amount of data, secure erase does not take too much time. But if you have a ton of file and/or a few really large files to erase, secure erase can take a long time to complete as it is doing multiple pass to write and overwrite the file's storage with patterns of data that make it extremely difficult to recover the original data.  That takes time.
    Finally, if you have been updating a document, previous editions may have been given over to free storage as new versions are written, such that when you decide to erase the file you may only be doing secure erase on the most recent copy.

  • Is there any advantage in using Vault over Time Machine?

    Hi all,
    Yesterday I imported around 6000+ pictures from iPhoto and consolidated them into my Aperture library. After much re-organisation into projects, folders etc. I decided to update my backup Vault to preserve all my hard work. The Vault is located on a connected external drive with plenty of spare storage. I had previously backed up successfully to the vault when there was only a few dozen pictures in my library.
    After initiating the Vault update process I then left it to get on it (and to have dinner and then watch the football...) and after several hours was dismayed to find that the process appeared to be stuck at just over 50% completion. It was obvious that no further progress was being made.
    I was also concerned that there appeared to be no mechanism to cancel the process and the only course of action I could take was to apply a Force Quit against Aperture - not something that I care to do, if I can possibly avoid it.
    After a rudimentary search of this community I saw that several others had experienced the same problem - although some suggested that a fix had been applied in recent versions (although I am running the latest version).
    Given this, I'm reluctant to use the Vault again - particularly as there appears to be no means of cancelling a stuck job. I do however use Time Machine, so my questions are:
    1) Do I really need to use Vault if I have Time Machine making regular backups of my Aperture library to an external drive?
    2) Does using Vault give any advantages over Time Machine?
    3) Is anyone else experiencing this problem with the current version of Aperture (v3.3)?
    4) Is there anyway of cancelling a stuck Vault update other than the sledgehammer approach of Force Quit?
    Thanks in anticipation,
    Simon.

    SImon,
    Vault and Time Machine address different needs. Probably you will want to have both.
    The advantage of Time Machine: incremental backups of previous versions, very compact storage. And you can integrate it into your regular backup of the whole system and include the regular masters as well. But the disadvantage: Time Machine decides for you, what will be deleted, if the backup drives get full. You do not have control over what will be saved and what not from the previous versions.
    The advantage of vaults: You can make full backups of your library for well defined moments in time - snapshots of important states. I'd create a vault, whenever I make a major upgrade of the system at least.
    Is there anyway of cancelling a stuck Vault update other than the sledgehammer approach of Force Quit?
    If the graphical user interface is unresponsive, like when updating a vault, you can use the Terminal to send the "termination signal" to Aperture: Sometimes this will succeed, even if the "Quit" button does not work:
    Look for the Process ID of Aperture in the Activity Monitor (launch Applications > Utilities > Activity Monitor" and click the CPU heading. This will bring Aperture close to the top of the list. Make a note of the PID number in the first column, in this case 66550.
    Launch a Terminal window and enter the following command:
    kill -TERM 66550           (insert Aperture's PID instead of 66550)
    This will send the "Software Termination Signal - TERM to Aperture, the same as pressing the "Quit" button should do, but send it directly, and not from the GUI that is unresponsive. This way I always succeded in cancelling a vaul update without force quitting. Not all processes can be terminated this way, however. The Terminal.app is also in the Applications > Utilities folder.
    Regards

  • PIX 525 UR With 1 4-Port FE, 1 VPN Accel Card

    Good day;
    I have a PIX 525 Unrestricted with failover.
    802.bin IOS
    There is 1 4-port FE and a VPN Accelerator card installed in each unit.
    I tried to install a second 4-port FE in both prime and secondary units and the following is the result.
    Once I power up both units the second 4-port FE mimics the first one. Although there are no physical connections to the second 4-port FE's, the port lights on the second FE's light up as the ones on the first 4-port FE.
    Example:
    1st 4-port FE
    Fa0/2 - physical connection - Light on
    Fa0/3 - no physical connection - Light off
    Fa0/4 - physical connection - Light on
    Fa0/5 - no physical connection - Light off
    2nd 4-port FE
    Fa0/6 - no physical connection - Light on
    Fa0/7 - no physical connection - Light off
    Fa0/8 - no physical connection - Light on
    Fa0/9 - no physical connection - Light off
    Also, when the second card is installed the first card will not function and this sets both PIX's as active.
    I'm somewhat baffled.

  • Any advantages of using HD in an SD project?

    Hi there,
    Apologies if this question has been asked and answered - I ran a search but couldn't find a "specific" answer if you will.
    I've been given the proposal of producing an SD project but utilising HD footage; which I know is possible!
    But the guy who is handing over the job is insisting we can take advantage of the HD footage within the SD project as it'll be larger than our PAL SD "canvas" [which I know is true], which means we can [and I quote] "zoom in and retain detail".
    I'm really not so sure this is possible!? As I was under the impression that any HD footage brought into an SD project would be automatically resized to fit the project dimensions!
    Could anybody kindly point me in the right direction? And to be honest I'd rather we have the piece shot as we intend it to look [or as close as] in the final edit, ie. cut aways, close-ups, wides, etc., rather than relying on a probable myth of the above!
    Many thanks in advance.
    Regards, Mark.
      Mac OS X (10.4.7)  

    Hi there Jerry,
    Many thanks for the reply and the warm welcome -- I've been lurking around these parts for months now, but it's my first post!
    Well, I'll be honest and admit to being shocked -- don't you hate when you're wrong?!
    I was absolutely certain that importing HD into SD would simply be re-sized to the SD dimensions! Oh well...
    But [and as you rightly said] I would rather see the material shot correctly for "correct use" in the first place rather than relying on the fact that we could possibly zoom-in [which is often an unatural move in interview situations].
    I need to convince the "guy" [as we shall now call him] of the need to storyboard and script [of which they will be rather than vox-pops] the end use of the interviews.
    Another day, another dollar... Or pound sterling in my case!!
    Many thanks once again.
    Regards, Mark.

  • Are there any advantages to using a Data Value Reference for LabVIEW Classes?

    Hi
    I recently came across an example where the developer had used a data value reference for the class cluster in LabVIEW.
    What are the advantages of doing this?
    Doesn't the use of LV objects already avoid the creation of multiple copies of data thereby reducting memory usage?
    Thanks

  • Encoding music video for Youtube - any advantage of using Pro (AME) over Elements?

    I am in the process of encoding some music videos for youtube.  I'm currently using Steve Grisetti's suggested settings from mid-2011 here:  http://forums.adobe.com/thread/623549
    What I'm wondering is if the Adobe Media Encoder provided with Premiere Pro (or another such program with more features than the Premiere Elements 7 encoder) would provide better results?   For example, I noticed those programs have options such as 256kbps audio, 2-pass, and Variable Bit Rate (which PE7 doesn't seem to have).  Would that provide better quality?  Of course, I need the very best audio possible. 
    Also, I've read from various other people's suggestions, that FLV is a better export choice than h264 since less recoding by Youtube is done- any truth to that?
    Lastly, would exporting to 1080 instead of 720 (and therefore giving youtube users the option of choosing either 1080 or 720) be better for the long term, or is there any reason why 720 is suggested?
    My videos are short and were edited from DVD vob files.  I've very new to encoding so really appreciate the suggestions!
    Thanks!

    I doubt that even a discerning ear to tell the original source Audio, after YouTube gets through Transcoding it for display. Also, viewers will be listening through their computer's speakers, and not a full home theater setup, where the Bit-Rate might make a slight difference. Also, most folk today, think that MP3's through ear-buds are "high fidelity."
    The only plus for using AME is that once you have queued the Project up, you can do other things, while it is processing the file.
    Good luck,

  • Advantages to using iMessage?

    Hi, are there any advantages to using iMessage if you're on a plan with unlimited taik and text? iMessage uses data on the 4GLTE network if one is not on a Wi-Fi connection, so why use iMessage when you have unlimited text messages? I'm curious; I like iMessages, but why use data if you're on a tiered plan if you don't have to?

        MaceWindu57, we want you to take advantage of every benefit available on our wireless network. The iMessaging feature works great for group text conversations and sending/recieving messages to iPads or iPods. Additionally, this option is also awesome when you're in a location that has no wireless reception as you can send iMessages over Wi-Fi instead. Lastly, iMessaging is a free way to send/recieve text messages for those that don't subscribe to a Messaging Plan.

  • Any advantage to dojng an A & I with retail Leopard vs. Upgrade Leopard?

    My Intel iMac came installed w/ Tiger and a "CPU Drop-In" DVD of Leopard. I need to do an Archive and Install to see if I can fix a hanging Finder. I previously bought a retail copy of Leopard for my G5, which I understand will install on either PPC or an Intel machine. Is there any advantage to using the retail version on my Intel iMac? I've read that the CPU Drop-In Leopard is not a complete version of Leopard, which doesn't make sense to me.
    Any advice would be appreciated.
    Message was edited by: WildBill

    a brody,
    Thanks for posting and your offer to advise.
    As for a backup, I have most of my data still on the G5. I've already done an A&I on the Intel iMac once witch did not fix the Finder issue. In getting ready to give an A&I another go, I backed up my Intel last night to an Ext. HD using CCC. There are three users on the machine. The other two users are not experiencing the Finder issue.
    Background on why I did an A&I in the first place: ran my newly acquired updated version of DiskWarrior on the Intel iMac. Turns out this version can build the directory but can not fix permissions because it's based on Tiger. I did not know this (wrongly assumed DW was entirely compatible with Leopard).
    DW tech suggested I do an A&I which did not fix the problem. An Apple tech yesterday suggested that since the Finder is only hanging on my (admin) desktop, that I create a new admin account and drag over my files either by using target Mode with G5 or getting them from the Ext. HD. However, I thought that maybe if I do another A&I, it might fix the problem. I'm also concerned that even though the other users on the Intel do not have the hanging Finder, that the previous ?A&I might not have corrected all the corrupted permissions.
    BTW, initially the Apple tech guy suggested that I do a complete Erase and Install, but in thinking further on it, thought just creating another admin account would be sufficient.
    What do you think?

  • USE 2 identical creative cards (XFI-Ti, ZS2, ...)

    Hi everyone, I?m currently testing Windows 7, news drivers of creative works fine and Microsoft allows to play the same sound on multiple cards/channels; different sounds on different channels witch is really nice.
    My problem is, and was also the case on Xp, if I connect 2 Creative identical cards, even if it's recognise by the system in the system management, it's impossible to access to the second one. Creative console is disable and also no more upgrade from creative website (hardware not recognise or detected)
    Do someone know any issue to use 2 identical creative cards?
    <p class="MsoNormal"><!-- [if !supportEmptyParas] -->?<!-- [endif] -->

    Now I must say, that is a great idea..........two cards in the machine at once? Please keep reporting on your results. I have seen users in other forums use the Microphone of their onboard chipset, but not the sound, and then use a Creative or Auzentech for sound. Two cards of identical brand and make though? I am curious... title="Smiley Happy" src="http://forums.creative.com/i/smilies/6x6_smiley-happy.gif">

    Hello KGDJ,
    Thanks for using Apple Support Communities.
    When there is a mismatch between the iTunes Store's records and your credit card company's records, you will receive an error message
    For more information on this, take a look at:

  • Any Advantages With A Mac?

    Are there any advantages to using an iPhone with a Mac, as opposed to using it with a PC? Does the iPhone work better/faster with a Mac, or is there no difference?

    I'm no Windows fan, but let's not make this look worse than it is.
    * For e-mail, you need to buy Outlook, 'cos the iPhone doesn't work with Windows XP Outlook Express or Windows Vista Windows Mail, right?
    It's supposed to work with Outlook Express. (Free)
    * For the Address Book, you need to buy Outlook (again) 'cos the iPhone doesn't work with Windows XP Address Book or Windows Vista Windows Contact, right?
    Doesn't work with Address Book, but not needed. (See above.)
    * For photos, you need to buy Photoshop Elements. I guess the new Windows Photo Gallery in Vista doesn't work with the iPhone?
    "iPhone uses iTunes to sync your photos from...any picture folder on a PC."
    A final question, how do you get photos taken with your iPhone onto your PC? I imagine there isn't a clever automatic way of syncing them from the iPhone to your PC. Is there the facility to manually drag the files off the iPhone and onto your desktop?
    See above. I believe Windows also see it as a USB camera, so it should automatically open it as a folder so you can drag the files to the folder of your choice. Since in IS a camera in Windows, I would guess other photo processing software in Windows would work too, just like any other camera.
    But you really do WANT a Mac.
