My best translation would be 'Stopped signaling'. Say I have an alarm button. I can push this button to send a signal. Then I release the button to stop sending that signal. Replace 'push' with 'assert' and 'release' with 'de-assert' and you get the meaning.

As a general rule, wherever you have SAS drives you can use SATA. There are exceptions, but they're more commonly in SAN type setups. The Dell caddies are easy to swap over between SAS and SATA I've done so many times, although on 1950's.

From my experience it is not necessary. I have a couple dozen Dell servers and all of them have a base windows install. Occasionally, there there may be a driver or tool (RAID monitor/managment) that you need to install, but as far as I know nothing is strictly necessary. Pretty much everything in the bundle can be separately downloaded from ...

Further to ErikA's answer... This terminology carries "up" from digital logic. When you say that a digital signal is "asserted" it's the same as saying it represents a binary value of 1. De-asserted is the same as binary 0. In your case, the message means that signal IERR was set to 0, i.e. turned off.

I'm not sure where this term started gaining usage in regards to error conditions, but I've seen it with several vendors. Basically, an error condition is present if it is "asserted". Then if at some point the error condition ceases to exist, a message is logged that said condition is deasserted.

openmanage is most useful for seeing the status of your raid, temps, etc that arn't available directly to the OS Several of the drivers will improve performance/functionality over the default windows ones. Usually you want at least chipset, networking and graphics

Yes... you can just swap them.

You first have to figure out where your bottleneck is, i.e., disk IO. Then figure out your usage patters and see if there is anything that might improve your situation. The sysstat package which has sar and iostat is a good place to start to collect the information. Chances are, the defaults are probably best :-)

Unless the VM's actually need that much CPU horsepower, I'd very seriously consider dropping them to one or two processors each. When a VM wants to use a processor cycle, all four cores of one of your physical processors have to be ready, which can cause some pain if anything else is going on (dom0 in this case). I'm more familiar with the VMware side of ...

This means you've either got existing E/L5310 Xeons or possibly new E5603 chips. I'm struggling to figure out what you want to move to as the only chip in that speed range that the 5310 can be swapped for is the E5460 but that's 3.17Ghz not 3.1. And if they're 5603's then the closest is the E5667's at 3.07Ghz but then if you're going to them you may as well ...

VMWare only support SAN LUNs as RDMs over FC/FCoE and iSCSI, there's no official way of doing this with local disks. HOWEVER if you google about a bit you'll find a few hacks that seem to work for some people, though there's no certainty that your kit will work until you try it, and even then you'll be in an unsupported situation. Serverfault is a site for ...

Try disabling the framebuffer in your GRUB settings. You can add a "nofb" to the end of your boot string. We ran into this exact problem on either a Dell 2950 II or III.

Since I haven't gotten anywhere trying to monitor the condition of the PERC 5i with MegaCLI in Nexentastor (I also tried Dell's Openmanage software but they don't have a version for Solaris), I've since installed a Dell SAS 6/ir controller in the 2950. This allows Nexentastor to see the disks individually in JBOD mode, and therefore Nexentastor can directly ...

What version of XenServer? If it is 5.6 FP1, install hotfix006 and hotfix007 and retry. About the cpu allocation, you shouldn't allocate more than you have, otherwise you're load the hypervisor scheduler with a huge amount of requests from the VMs. Also, when the VMs are running sluggish, if you run top on dom0, is there any process taking a huge cpu load? ...

I had the same question a few weeks ago. The Dell support person I talked to claimed you could not just swap the drives, but had no explanation for the fact that there was not a separate part number for a SAS backplane. My own research on the PERC part, the backplane, and the SATA/SAS specs would seem to indicate that they are completely interchangable.
