It should be noted, that there may be other steps needed, depending on the distribution. Most notably the drivers (thanks for pointing that out @ewwhite). Boot the new server from livecd/usb. Prepare partitions and bootblock on the new drives. Depending on setup, this could be done by copying MBR/bootblock. Make the filesystems. Do an rsync from old ...

Two things: I would build anew and rsync data. Your downtime allotment/window seems to be too short. 30 minutes can work in specific situations, but shouldn't YOU be dictating the realistic downtime requirement based on what it takes to actually accomplish the work? Depending on the data contained within each server, the amount of data churn, and your ...

Yes, enterprise SAS disks spin at a fixed rotation speed. They will not go into power or energy-saving modes like certain consumer drives.

It's almost like there's a guide you can follow for this :) But the quickest option for you may be to bootstrap your Windows 2012 R2 installation by using the HP Intelligent Provisioning Utility baked into the system BIOS. Use the opportunity to update the system BIOS and firmware as well. The Smart Array RAID controller on the Microserver is the culprit ...

Don't do it. There's no reason to pursue trying to convert an 11 year-old server to SATA. There's absolutely no upside to it. The backplane is not required to power the server on, though.

I don't have any 12-bay servers to test with right now, but understand that there's an expander backplane in between your disks and your controller. From the HP SSA utility: Enclosure SEP (Vendor ID HP, Model DL18xG6BP) 248 Device Number: 248 Firmware Version: 2.20 WWID: 50001C1071540013 Port: 2I Box: 1 Vendor ID: HP ...

I'd recommend buying from the manufacturer of the server and matching the specifications of the existing power supply, assuming you're looking for a replacement. If the manufacturer is no longer reachable or in business, I'd try to source components from eBay or off-lease/used hardware vendors. Can you provide any detail on what you're working with?

You don't even need the ILO for this. If you have access to the operating system, you don't actually need to do this through the ILO. You can download the HP Service Pack for ProLiant DVD .ISO to the server and run it, following the instructions along the way. You can download the individual firmware updates for that platform piecemeal from the ML370 G5 ...

Do you know the IP to the iLO in question? Do you know the credentials? If not, you'll need to use one of the following methods, up to and including powering off the server and using the dip switch block on the motherboard: http://h20564.www2.hp.com/hpsc/doc/public/display?docId=mmr_kc-0115524 Then access the iLO via https on the IP you have set with the ...

Please examine the ILO log and the IML log. The server will tell you exactly what's wrong. But really, I wonder if you may have caused another issue while swapping components looking for a solution. If you're seeing an error on a particular DIMM slot, there may actually be a problem with the CPU socket for the processor associated with that memory ...

You need to provide more information, especially log entries right before the system rebooted. However as far as I can see it may not provide more information. Check other logs such as syslog. The most common causes in my experience for sudden restarts without any indication really of what went wrong is often hardware related. Otherwise the kernel mostly ...

The motherboard you are using calls for RDIMM (Registered RAM). You are using UDIMM (Unbuffered RAM). ECC Registered RAM is standard for most Xeons except for the E3 models.

Resilvering is a vdev optionation, as you implied only the storage devices in that vdev are used to rebuild the new device. I'm not sure why it quotes the full size of the zpool, but I suspect the developers borrowed code from the scrub functions, or that it simply quotes the full zpool size as that would be the worst case scenario.

The mainboard has a super IO chip that in addition to doing prehistoric stuff like handling floppy drives (even though the board itself doesn't even have a connector soldered for it) has several analog inputs that can measure voltage. The rest is just some resistor magic that's used to lower the voltage range (the chip I linked can only accept up to 2V), ...

The others are spot on about the sensors but here's a short answer to what you're really asking: 144 watts seems quite low for a system with 4 disks and 2 quad core CPUs. Yes, 144 watts represents only the via-the-motherboard draw, not the draw of anything else connected to the PSU directly. It won't include, amongst other things, disks. 144W sounds ...

There is something wrong with your hardware - this can be the hard drive itself, the motherboard, or maybe the cable connection is noisy. Use badblocks to check the drive. But I suggest to back-up all the data beforehand, as comprehensive tests can kill a dying drive.

If your previous OS version is able to handle the new Hardware (mostly RAID controller) you can give a try to CloneZilla. To check if it is possible to move from one hardware to another you cad pass all data from old to new server doing some tricks with dd. Boot the new server with a live distro like SystemRescueCD, configure with an IP address and a dd ...

Ask your co-location facility or datacenter for their suggestions on how to approach this. If the bandwidth is really expected to require 10Gbps, you'll need to scale up your firewall and networking infrastructure to meet the need. So if that means a better firewall, it is what it is. Your budget option would be an open-source firewall built on commodity ...

Dual-ported SAS disks are not intended for performance, but rather resiliency when used in multipath SAS array configurations (e.g. external JBOD or SAN situations). For single server or internal storage purposes, there's no benefit or gain achieved by using both ports. If you need better storage performance, please scale with disk count, RAID controller ...
