Hey guys

I setup 2x SSD's samsung 1TB on raid1 that is gonna be used for a few VMs for the next 2 months.

i setup raid 1 with BTRFS. Setup a single lun with advanced features. connected to it with ms iscsi initiator.

Everything works. I see the drive, i initialize it and format it with NTFS.

The Rackstation is connected with 1 gb cable to a gigabit switch. Jumbo frames 9000 enabled.

Big files transfer really really fast. back and forward. (maxed out 125 mb/s)

What i have an issue is, when i run atto benchmark on it, all the READS are maxed out at jokingly 5 to 11 mb/s??

The write speeds are doing better but not by much until i reach bigger files.

I am monitoring cpu and network usage on the GUI but there is absolutely no load / stress on the machine.

Supposedly this rackstation can do better than that?.

Here is what i have tried:


- Enable / disable jumbo frames = no change

- Trying out EXT4 instead of BTRFS = Gave around 20% boost but reads still stuck at 11 mb/s

- Trying different allocation sizes with NTFS (4k to 64k all the way) = small difference

- Trying ReFS = No difference

- Tried SMB3 mapped drive = no difference.

- Turning off all unnessercary services = no difference.

- Tried 3 different machines with different OS (server 2012R2, server 2016 and server 2019) = No difference

- Tried the raid "Sync faster" options = gave better results with normal operation but benchmark still shows bad.

- Tried directly …

I have a problem with server HP DL380 G4. My server does not show anything in display/monitor.
I removed memory/RAM and started the server I am not getting the beep sound. So I arranged another motherboard and I still didnt see anything in the screen/monitor.
What could the issue I changed power supply as well. I just want  to start the server and run P2V and convert to virtual.
Appreciate your guidance.

Our current RAID devices are getting end of life, and I’m looking into the possibility of upgrading to a more robust system. The important goals are high availability.

The image shows one possible route. I'm investigating:
1. Is there a better way to do this? (Or is this a bad way to do it).
2. The best tools for accomplishing this.

IF POSSIBLE, when all four enclosures are working – I’d like all 4 ethernet cables to be serving data – to overcome bandwidth problems.

On the left (current) is our current setup.
Top: RAID controller with 24 slots (+ 2 SSD slots in the back for the OS).
Middle: The 12 slot chassis (which may be failing)
Bottom: chassis (without motherboard) with 24 slots.


Can you advise a setup for something like this?

I have inherited a Megaraid SAS 2208 RAID (24 drive slots) with two additional external enclosures (one 12 slot, and one 24 slot)

The problem is; the 12 slot enclosure is demonstrating hardware problems. It is well out of warranty and has no support contract.

I'm considering buying a new enclosure and moving the disks. However, I don't know how to recreate the RAID6 virtual drive WITHOUT losing the data on the disks.

Is this even possible?

Restoring a ShadowProtect backup on to a new RAID5 array. This is Thinkserver TS430 with LSI Megaraid 9240-8i controller (no cache or battery backup) supporting a 3-drive RAID 5 with 450 GB Cheetah drives. Original array has been having issues, and We decided to replace with a set of 3 identical but "refurbished" drives from ServerSupply.
Backup of full 650 GB system volume (server only has one voluem) on to a SATA drive on same controller takes 2.2 hours. We attempted a restore to the new array and found that restore times were a full day or more- the transfer rate was only 5.75 MB/s.  Is this normal for this hardware or are we missing something in our configuration of Shadowprotect?  We have a bootable USB stick that is allowing us to do the restore.
My options are
1. Stick with the original plan and do the restore over a weekend to not have business impact to customer
2. Change configuration for restoring to another destination, like a Single or RAID-1 SSD

Hi. I have an older HP ProLiant server and have a quick question about RAID.
The server has 8 hard drives.
The first 2 were used for a RAID1 setup and that's where the OS was installed (Server 2008 R2).
The other 6 drives were setup in a RAID10 config and housed a COPY of the company's data.
I decided to replace the first 2 drives with SSDs and was thinking that the other 6 drives would still be accessible after the OS was reinstalled on the 2 x SSDs.
I noticed when I initially booted into the RAID setup, I saw a message stating that some drives and configs were removed and such.
It's not a HUGE deal to recreate the RAID10 config on the other 6 drives and copy all of the company data again, but it is very time-consuming.
Just wondering if I have any options before I recreate the RAID10 config and copy everything all over again.
Thanks in advance.

Hi,

System is a PowerEdge R710.with PERC H700 integrated controller.  The virtual drive in question is RAID 5 with 3 drives. I have been monitoring controller logs weekly, and running consistency check for the past 3 months with 0 issues.  Suddenly yesterday, OMSA is showing 1 drive as predictive failure.  I went through logs and see a bunch of unexpected sense logs many of them stating "corrected medium error", but I do not see any unrecoverable errors.  I went onsite, offlined drive, then inserted new Dell branded drive.  Rebuild completed, but the new drive is also reporting as predictive failure.  I went through logs again, and notice many more unexpected sense logs during rebuild process.  I then ran consistency check, which again had many unexpected sense logs.  Drive is still in predicted failure state, so I replaced drive again with a new drive.  This time, after rebuild drive was not showing predictive failure.  Just to be sure, I ran another consistency check, which put same drive in predictive failure state again.  There are again a bunch of unexpected sense logs many of them stating "corrected medium error".  I am unsure how to proceed.

The firmware for controller, drives, & BIOS are all up to date, but IDRAC6 & Lifecycle are out of date.  IDRAC6 is at 1.92.00 (build 5) and Lifecycle is at 1.4.0.445

Please let me know your thoughts.  If you recommend updating IDRAC6 & Lifecycle, please let me know where to find updates and steps for updating.  I am a …

What is the best config for VMWare 6.7 for the following hardware: HP DL380 gen 10, 2 processors (8 core) with 64 GB memory each, 6 x 960 GB SSD, 2 x 4 ports networkcard

I am talking about :

1) Which raid config (Windows servers and some Linux machines will run on as a guest, 10 in total)
2) Network setup (teaming or not),
3) How to get the best performance out of this hardware config

I have dell t620 with a perc h710. It is configured raid five with 6 930g sas drives with a capacity of 4.5t.

A few days ago i saw on a reboot the there was a foreign config on the drives. as the os was booting properly i cleared the foreign config.

After hat I noticed that the virtual drive is in a degraded status. Drives 1-5 are online but drive 0  appears unassigned with a status of "ready". the only option the controller gives me is to set it up as a hot spare. I tried that and it set up that way but it wont integrate to the basic drive. How do I get it to reintegrate?


Thanks

What's the difference between a Data Center Internal Hard Drive vs a Network Attached Storage Internal Hard Drive? Can a Data Center Internal Hard Drive(s) be used in RAID? Out of curiosity, what brand hard drive(s) does Google in use their Data Center?
