H730P with more than 8 drives

We have a range of R730xd servers with 2 x controllers RAID H730P, each with a 8 x 6 GB/s SSD attached. Servers are sold as servers '12 + 12' drive, and the chassis has bays for 4 more disks per controller.

When I read the H730P specification, I see that it is described as a controller to 8 ports, that raises questions.

(1) are all the bays of 12 drives in each "section" usable? So, I guess because the server is sold as '12 + 12'.

(2) are all 12-Bay by controller managed by the H730P, or 4 of them accompany the ports on the motherboard? If so, which of them are that they have limited (put in cache, RAID support, performance,...)?

Best regards
Brian

pcore
Can all 12 drives operate at full 6 Gbps?

Yes, all 12 drives can operate at 6 Gbps. If you want to get the full 12 GB/s SAS drives then you could fill a maximum of 8.

pcore
I thought 1 player would use 1 port, or does he shares somehow port? If so, 8 drives operate at full 6gbps any berries I use or do I have to consider?

Yes, 8 ports use a form of port sharing. If you fill in more than 8 records 8 ports can divide. You can fill up to 16 drives per controller to achieve 6 Gbps. If you fill more than 16 that they will work to 3 Gb/s. Each port can support up to 4 devices.

Thank you

  • Any laptop computer, with more than one drive Bay?

    Latitude D400 a friend needs more storage, the thing in there is a {cough} 40 concert and she really needs more.

    I thought I read earlier that Latitudes had place for a 2nd disk, either stacked on each other or a 2nd Bay or something. I see that in the documentation anywhere, so I guess it was simple elucubration on my part.

    To preserve its OS etc then, I suppose that there is no way around using some utilities like ghost to save far picture of current player and then restoring it in a new HD?

    Hello

    First of all I must say it is really hard to say something about it without having heard this noise you want to say.

    Generally speaking, it of normal that you hear some noises during writing or reading process of the HARD drive.
    You can test your HARD drive for bad sectors using Drive Fitness Test. Which is a freeware tool that can check the HARD disk.

  • Cannot start a virtual machine with more than 1 CPU socket added

    I've set up a few boxes of ESXi 5.5 with the free license in recent weeks, they have all been without problems so far. All 4 servers have the same exact hardware

    Environment:

    Dell Poweredge T620

    E5-2630 2 Intel CPU

    40 GB OF DDR3 ECC RAM

    ESXi is installed on 2 x 146 GB 15 K SAS drives RAID-1

    Data for virtual machines store are 8 x 600 GB 10 K SAS RAID-10 disc

    Guest operating system is Server2012r2 on all virtual machines

    Installed it on ESXi 3 previous were conducted with custom ESXi 5.5 Dell without problem.

    The 4th is where I will have questions. I used the following ESXi installed just in case there is a bug somewhere

    5.5 of VMware ESXi

    ESXi 5.5 customized by Dell

    5.5 U1 of VMware ESXi

    Any version of the ESXi I use I can't have a virtual machine to begin with more than 1 CPU socket added to it. The virtual machine does not start even the VMWare BIOS. I tried the Bios EFI as well with no luck. The error message I get in the events is ' fatal error VMware ESX: vcpu (vcpu-X)-X:VM - entry failed; Valid VMCS (error code 8). The vcpu-X is always another. I have attached the log file is created. If I give the VM 1 single processor TI starts very well. I'm at a loss as to what could be the issue.

    Problem is solved. I caught another server with identical hardware, verified it worked properly, then started to swap parts between them. Turned out to be CPU1. Once this has been replaced from a working server I have not had any problems. Warranty has been appealed.

    Thanks for all the help!

  • need to vmdk with more than size of 2 TB

    Hello

    I install ESXi5 on 2 x 72 > RAID 5 and create VMs on it (2008), now I have to create vmdk and assign it to this virtual machine with more than 2.5 TB of size.

    I creat new RAID set and now I have data store with 3 TB space, but I can't to creat 2.5 or more to vmdk

    How can I create?  How can I activate the RAW Disk Mapping on the local storage?...

    you will not see local hard drives, it is already in the RAID, then only you can see the raid volume. Which is given below

    MPX.vmhba2:C0:t0:l0<-- disk="">

    MPX.vmhba2:C0:t0:l0:1<-- partition="">

    MPX.vmhba2:C0:t0:l0:2<-- partition="">

    It is not recommended to violate the recommended settings and rules given by vmware, it will raise many problems and if it is in production you will be screwed. On the thing you can do, is to create dynamic disks and create a split volume.

    http://www.Techotopia.com/index.php/Creating_and_Managing_Simple_and_Spanned_Volumes_on_Windows_Server_2008

    If you still want to go for RDM local pause, the RAID and see if it detects the ESX or not and if you can see the individual disks and if you are able to make RDM with these discs, then back to the VM will intervene only individual HDD so no raid and protection? So it is very risky

    Reference:-issue voting disk

    answered by Silva

    (1) why don't we not create an odd number of voting record?
    With regard to the vote of the disks are concerned, a node must be able to access exclusively more than half of the discs with the right to vote at any time. So if you want to be able to tolerate a failure of n disks to vote, you must have at least 2n + 1 configured. (n = 1 means 3 discs with voting rights). To you can configure up to 32 disks with voting rights, to the providing protection against the 15 simultaneous disk failures.
    Oracle recommends that customers use drives 3 or more with right to vote in Oracle RAC 10g Release 2. Note: For best availability, 3 files of voting should be separate physical disks. It is recommended to use an odd number as 4 drives will be more highly available than 3 disks, 3 1/2 is 1.5... rounded up to 2, 4 1/2 is 2, once we lose 2 discs, our cluster fails with 4 disks with voting rights or 3 discs with right to vote.

    (2) only the cluster checks actually for the counting of the votes before node eviction? If so, could you expain this process briefly?
    Yes. If you lose half or more than all your discs with right to vote, then nodes get evicted from the cluster, or nodes to expel from the cluster.

    (3) what is the logic behind the documentaion note which says "each node must be able to see more than half the disks with right to vote at any time"?
    The answer to the first question is will also answer this question.

  • After using groups of tabs earlier today, now whenever I close FF with more than 1 open tab, FF don't ask me to confirm before closing

    After using groups of tabs earlier today, now whenever I close FF with more than 1 open tab, FF don't ask me to confirm prior to closing. FF always asked me to confirm in the past and no settings have been changed before you try tab groups. Then when I open FF it again all the tabs I had open are still there. I tried refreshing FF and erase history, but that did not work. It's almost as if FF think windows and tabs I have open are a group of tabs, and he won't let me get rid of this group. How to stop groups of tabs now that I have them? Or is there something else? None of this was going on until this morning, I played with tab groups. I was curious what it was - it's going to make me kill one of these days lol.

    Note that using "show my windows and tabs from last time" as the start setting will also prevent Firefox to display an alert when you close the window.

  • Hello, I want to build several video clips with more than 500 images (pictures) of each clip. I need to apply a different video transition effect to each photo. It might even be random effects. I see that I can apply a unique to all p transition effect

    Hello, I want to build several video clips with more than 500 images (pictures) of each clip. I need to apply different transitions video effects by alternating each photo. It could be random effects. I see that I can apply a unique pictures transition effect at the same time, but how to apply different transitions not one by one? I could do a clip applying different transitions manually as I wish between hundreds of photos, but I would like to be able to repeat all the transitions of a new video by changing only the photos. Is this possible? Or a tool to apply random transition effects between photos? Or a way to automate the actions to apply different transitions similar to what we can do in Photoshop? Thank you!

    But how to apply different transitions not one by one?

    You can not.

    If you wish to make a slideshow with all the transitions better fantasies use something like Pro Show gold.
