What is the maximum flow of PERC 5/E + MD1000? Confused in the calculations.

Hello, I have read many articles on PERC 5/E and after the last section of the Dell Web site, I'm totally confused. I don't have much experience with these things.

http://www.Dell.com/downloads/global/power/ps3q07-20070368-Olivarez-OE.PDF

My question is: if I Garland 3 x MD1000 and hang it in a port, which is the maximum flow? How can I type 1 Gbps? Is maximum 300MBps by port (wide port?) or PERC 5/E? How would I go over this?

(the link provided in the upper part) "The PERC 5 is connected to the server through a x 8 slot PCI Express nominal of 2 Gbps (although some systems can use a x 4 PCI Express slot, rated at 1 Gbit/s). The PERC 5 has two wide ports of SAS to connect the controller to expanders. Each wide port is a combination of four ports SAS estimated at 300 MB/s each, providing a flow of 1 200 MB/s per total Expander or 2 400 MB/sec. »

I understand more channels, but what exactly do mean by "four SAS ports?

They mean that each physical port is somehow 4-port SAS? So there x 4 double SAS? Then, each port has a flow rate of 1.2GBps? I understand it correctly?

Please someone explain simply. Thanks in advance!

It would be 1.2 GB/s. 5th PERC has two connectors for two different channels. Each of these connectors consists of 4x300MB/s ports, so each channel is capable of 1.2 GB/s. It's theoretical. Will not actually be able to reach this number as there is overhead to consider. The document States 80% is about the max possible, so that you to put approximately 960 MB/s.

This is the logical ports. This connector is used to a channel. The channel consists of 4 logical ports.

Yes, that is essentially what it means.

Thank you

  • Must be able to enter information where the calculation is present

    I have a form in Acrobat Pro, which is used to provide a fee. If someone is being reimbursed for miles, I need to calculate 0.56 * the number entered in the field 'Miles' that continues automatically in the "Amount" field using the calculate function. However, if someone needs to be reimbursed for anything other than miles, nothing can be entered in the 'Amount' field because a calculation is - even if it is zero... How can I fix a person can enter a different amount if the miles are not used? Is there a way to tell if something is entered in the mile, otherwise leave blank to get into computing, and allow data to be introduced?

    It is not difficult and it could be something like the following:

    Custom calculate script for amount field

    (function () {}

    Get a reference to the Miles field

    var f = getField ("Miles");

    Perform the calculation if a change in the

    Miles field, that's what triggered the calculation

    If (event.source & event.source = f) {}

    Event.Value = util.printf ("%.2f", 0.56 * f.value);

    }

    })();

    If you do not have the read-only field (as you normally would for a computed field), the user will be able to change the value of the field.

  • What is the maximum size of HARD drive, I use in my dc7600 CMT

    I use a HP dc7600 CMT, which works well after the upgrade to a Samsung 128 GB SSD Intel Pentium D 3.4 GHz, 4 GB of RAM and an AMD Radeon HD 6450. I'm under Win 8.1 Pro x 64, with the most recent upgrade and have absolutely no problem. Now, I want to add a second internal HDD and I wonder what is the maximum size that I can go to. I can't go up to 2 TB, or am I limited to a lower number? 1 TB? 500 GB? 250 GB?

    Will be happy to help here, especially if he actually tried to apply in practice.

    Thanks in advance.

    Best regards

    Hello:

    In theory, you'd be limited to 2 TB.

    The biggest HARD drive I have ever installed in my dc7600 CMT was a 1 TB of HDD, so I can't confirm that a 2 TB drive will absolutely work.

  • What is the maximum capacity of the disk for Satellite L300-1EI?

    Hello

    I have a portable Sattelite L300 - 1EI Nodel PSLB8E - 05W013H2.
    Currently, I have a hard drive with a capacity of 120G.

    There a lot of bad sectors.
    I would like to know what is the maximum capacity, by that I could replace.

    Thank you

    Unfortunately, you will not be able to find this information. What you can do is to check this forum using the advanced search option in the hope that you find some similar discussions.

    My advice to you is: buy 300 GB HARD drive, and I'm sure that you'll be happy with it.

  • Satellite 2400-103 - what is the maximum size of HARD drive?

    Hi all.
    New here.

    Nobody knows what the maximum hard disk size is for a Satellite 2400-103? This laptop has a 30GB HARD drive which is complete at the moment and I'm moving to a 160 GB unit.

    Used software - DiskCopy - clone Moose 30 GB of cloning to the new 160 GB drive. This creates a partition on the disk that is the same size as the original (about 28GB). If the new hard drive is installed on the laptop at this point, the laptop will be start OK. If I use a partition manager - Partition Magic - to resize the partition to the size of the new disc (about 150 GB) then the laptop does not start.

    Would it because there is a limit on the size of the hard disk supported by this laptop?
    If so, what is the limit?

    Thank you and best regards.

    Mike

    Hello!

    Satellite 2400 is very old notebook, so I think it has a limitation of LBA 28 bits. This means that you can only use up to 128 GB of free space so the maximum capacity of the disc HARD would be 120 GB. So I think that's the reason why the computer laptop can-t start successfully with the 160 GB model.

    In your case I bring back the 160 GB model to the computer store and ask one another 120 GB one. It should work normally

  • Satellite Pro 4600 - what is the maximum size of HARD drive?

    My age Satellite Pro 4600 has a 20 GB HARD drive. These are now very difficult to obtain, does anyone know if superior capacy HDDs can be used and, if so, what is the maximum size of the HARD drive.

    (Despite his age that I always use the Satellite Pro for some jobs).

    Hello John

    Satellite Pro 4600 is old enough for laptop and it is not easy to find the exact info. The fact is that this laptop comes with 10 and 20 GB hard drives.
    My opinion is that you can use 30 or even 40 GB HDD. I think that 30 GB new HARD drive should be enough for your some jobs.

    What do you think?

  • Portege M200 - what is the maximum HARD disk?

    Hello

    I need to know what is the maximum capacity of the hard drive that is supported by Portege M200.

    Hello!

    I guess that the Portege M200 is equipped with an IDE HDD interface. This means that the laptop has a limitation of LBA 28 bits and so it can only manage s HDD up to 128 GB. If you can use a 120 GB HARD drive in this notebook.
    If you want to learn more about the limitation of the LBA you can look on Wikipedia or here: [www.48bitlba.com].

    I have good experiences with Seagate drive HARD Hitachi s, but you can also buy another HARD drive. ;)

    I hope I could help you.

  • What is the maximum capacity of the disk for Portege M700?

    Does anyone know what is the maximum capacity of disk for Portege M700?

    Thanks for the reply

    As I m wrong not the Portege M700 does support a SATA HDD.
    In this case we must avoid any limitation of the size of the HARD disk
    Usually, you can use almost all SATA 2.5 hard drives in you M700.

    It seems therefore that the laptop is already upgraded to the maximum RAM.

    Hello

    I have to re - install the factory installed Win 7 on my Satellite A500-1 because I'm not able to install SP1.
    The cause is that inside Win 7 product information is missing.

    With regard to what I like to install a new HARD disk with more capacity (400 gb current).

    What HARD drive I can install and what is the maximum capacity (1 TB, 750 GB)?

    BIOS is updated.

    Any advice is welcome.

    Thanks in advance

    Hello

    To my knowledge, there is no limitation of the capacity of the HARD disk since the SATA controller is used and the SATA controller should support over 400GB.
