I have a desktop computer (Alienware) with four internal hard disks, with a RAID motherboard.  Two of the disks are striped (the c:\ drive) and the other two disks are mirrored (the d:\ drive) and contain all my data.  The c:\ drive contains my operating system (Windows 7) and all my programs.  I want to replace the c:\ drive disks with 2 SSDs.  I want to clone the c:\ drive and then transfer this clone to the 2 SSDs, which will constitute the new striped c:\ drive.  I have cloned and transferred an old hdd's content to a new SSD, but without RAID.  It was easy.  But how do I do the same with a RAID system?  I'm at a loss as to how to proceed.  

Thanks, WmABradnan

Hello everyone.

For starters, I do not make a lot of money in my self-business.
So, I have to get what I can get, in order to grow.
With that said.

I have just purchased an Intel SR2500ALBRP
The motherboard: S5000PAL

In the following image, you will see a BLUE set of SATA cables with a single PLUG at the end.

Now, The PCI riser assembly has only a NIC Card on it with DUAL 1G nics.
My question is simple.
WHAT RAID Card do I need to get, to connect this with?

Thanks.

Hi, I have an odd question that would like to know what others are doing these days.  I know keep doing the same thing because that is they way it has always been done, isn't the best choice.

I am setting up a RAID 1 array on a HPE ProLiant DL360 Gen10 server with Smart Array P408i-a.  In addition, I have 3 HPE 300GB SAS / 12Gb/s HDD's.

So, my intent is to setup a RAID 1 array with a hot spare.

This will be supporting a Windows Server 2016 - Standard domain controller.


With all that being said, what strip size would you use in this scenario?  64KiB?  128KiB?  256KiB?


Currently, the default is 256KiB.


Just curious.


Thanks in advance.

RAID levels 0 and 1 can be combined to make a stripe of mirrors (RAID 10) or a mirror of stripes (RAID 01) configuration.  Which implementation would you prefer to use and why?

Good day,
We have a VM host that runs two server machines.  The first is the DC/FS and it works great.  The second machine is a terminal server.  It constantly is freezing on the users and it is getting frustrating.  Here is some info:

Host machine is running Server 2016 Standard.  Its specs are:

HPE Proliant DL380 G9
Xeon E5-2620 v3
32GB RAM
RAID 10 for the virtual disks

Server is stable, no issues.

The host machine allocates a large portion of RAM to the DC and the TS.  The DC currently has 8GB and 8 virtual processors.  The TS has 10GB RAM, and also 8 virtual processors.  Originally I had the TS with less RAM and processors, but in trying to fix the freezing issue, I increased the resources.  I plan on bringing them back down.

The TS has only 3 users signing in.  They use the same domain account to log in to the server.  The TS is configured to allow the same user to log in multiple times.  It is light usage.  The TS exists to run only one program.  While using that program, the users may open Word or Adobe, but not much of anything else.  About 4 or 5 times a day, the server just stops responding to that user.  The other users logged in do not experience the same.  It will just spin and spin.  The remote connection never breaks.  Frustrated, they just click the x on the top blue ribbon, and re-log back in.  Then its totally normal until it freezes again.  

During the freeze, the internet is working normally, the others users aren't affected.  A VPN …

Can i convert a mdadm from raid 6 to raid 0

I have a machine with 10&10TB of data in raid 6.

I'm looking to convert to Raid 0

I dont really care if I lose the data (I have several copies) I just would prefer daving the time off wiping machine - raid 0 - then transferring it all back again.

Physical Disk 0:0 was replaced. There was an option to make it part of a RAID and once I selected that option the "State" immediately went to "rebuilding".
I look at this 3 days later and this is what I see:
Hovering over either triangle shows Status: Non-Critical
The only available tasks for disks 0 and 1 is offline
There are no other tasks listed for disk 2 (just shows Available Tasks) or disk 3 (just shows No Task Available)
I inherited this server. It is set up in a RAID 10... not sure which disks belong to what though
I think my first concern is disk 0... then the foreign issue with disk 3.
Thoughts?

I have decided that Surveillance vs. NAS hard drives are more about marketing and not much at all about technical spec's.
Do you agree or are there technical differences worth mentioning?
I've looked but not found.

I'm interested because I'm about to set up some file server drives that have pretty modest demands re: speed.
So, I don't know that rpm matters all that much and it appears that cache sizes are the same.
I'll likely put in 10TB drives in RAID 1.

Hi
I have a Dell R220 Server running Windows 2012 with a PERC H310 Adapter
The server had 2 x 2TB hard drives in a RAID 1 array
We have replaced the drives with 2 x 8TB drives

Steps:
Replace Disk 0:1 with 8TB drive
Boot into OS and launch Open manager
On the Physical Disk windows, select the available task to convert to RAID type disk
On the Virtual Disks Page, select the available Task to replace Member Disk
Select Disk 0:0 as source and 0:1 as destination.
Wait for Rebuild to complete

Replace Disk 0:0 with 8 TB drive
Repeat process as above but choose 0:1 as the source and 0:0 as the destination
Rebuild now complete

Within the Physical Disks page, Physical Disk 0:0 shows as Online with no available task
The properties of disk 0:0 show
Capacity 7,451.00GB  
Used RAID disk space 1,862.50GB,
Available RAID Disk Space 5,589.00GB

Physical Disk 0:1 shows as Ready with available tasks to Assign Global Hot Spare or Convert back to non-raid. The properties of Disk 0:1 are
Capacity 7,451.00GB  
Used RAID disk space 0.000GB,
Available RAID Disk Space 7,451.50GB


The Physical Disk page shows State Degraded, Layout RAID-1, Size 1,862.50GB
Available Tasks are Delete, Assign/Un-assign Dedicated Hot Spare, Rename, Change Policy and Replace Member Disk.

The Raid has obviously worked as it replicated the drives both times and in the Windows Disk Management console the Drive shows as one drive so all good there.

I am still left though with only …

Hi I have a Dell Perc 740p RAID card I just put in a computer, the computer recognizes it but I can't get in with ctrl + R.  I see the post message, but this one dosen't say press ctrl + R to get into Bios.  it says...

"PowerEdge Expandable RAID controller BIOS copyright AVAGO Technologies"

Then Initializing virtual drives, then goes on it's marry way.

Question: is there another way to get into Bios?  Am I dooing something wrong?

Thanks all

Our domain servers are working on VMware Workstation virtual machine. Recently we decide to move them to ESXi 6.5 that's installed on DELL R720 and T30. But the problem is ESXi cannot manage RAID disks. I installed MegaRAID on ESXi, however it only can monitor status, and I can't find the function to schedule check and report disk status. I also bought a LSI SATA+SAS Host Bus Adapter with RAID Controller and install it on T30, but I still need to reboot then access RAID control page to create/change RAID.

Is there a program based on ESXI to let me manage, control RAID disks without shutdown ESXI? Or at least I need a program to check disk status and email me the check result.

Thank you very much for any suggestion.

Hi I am trying to setup a RocketRAID controller, its a 3740A.  I have three disks on it, and I created the raid 5 array, but it keeps saying it's not initialized.  Also I can't see the disk in the vmware installer.  I am familar with perc controllers, but not this rocket one.  

I clicked on the manual on their site, but it comes up that can't be displayed.  The unit only came with a sheet to download the manual, but it is the same link as on the site.

Question, how to I create a raid 5 array, or at least initialize it?

Thanks all.

High Point has a SSD7103 RAID controller that supports 4 NVMe drives in RAID 0, 1. 1/). Don't NVMe drives have the sames issues with TRIM that others SSD drives have where if you put them behind a RAID controller TRIM just won't happen?

   Are SSD and NVMe drives so reliable that RAID 1 is all the fault tolerance you'll ever need?

   Are there any NVMe RAID controllers that anyone has tried in a small server environment or is that still pushing it?
