Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Hi

Info on server :
DL 385 G8
Server is running VMware ESXi 6.0
Controller card P420i

We rebuilt 2x600GB SAS drives in a raid 1 to 2x1200GB without any issue.
When trying to expand the disk space on the logical volume it prevents us of doing this or there is no option as it complains there is a 600 GB Hot-spare drive configured to the same array (Array A).
I do not have any option in ACU on removing of Hot-Spare drive, i have the option to erase the drive.
Will an erase of the drive tell it that it is no longer a hot spare drive ?

How can i remove the Hot-Spare drive ? I would like to repurpose it to another Array B as a hot-spare.

Update, i tried to do this from ESX console using hpacucli using command ./hpacucli ctrl slot=0 array A remove spares=2I:2:8
but got Assignable spares not available (see attached screenshot).

Show command on Array A

I am tryiong to backup a Western Digital NAS to 2 external USB hard drives. The NAS is running Windows 2008 Storage essentials.

The drives need to be rotated with a drive being taken offsite on alternate nights.

It also needs to send an email notification on job completion or failure.

I have tried using the built in backup utiity in Windows but it doesnt have email notification. I have tried using task sacheduler to send email when certain criteria are met but it just wont work for me.

Does anyone have any suggestions for a simple, free backup solution that will do these 2 things?

Thanks

Hello,

I'm trying to extend the volume on Server 2012 R2, but for some reason the Extend Volume is grayed out. I tried to do this under Disk Management and under the Server Manager but it says it only has 1MB of Unallocated space even though it has 371.50GB of Unallocated space. Any clues as to why it won't let me extend?

Please see screenshots attached.

NIce article although the author doesnt seem to know that there are two measures of a disks performance
1) Throughput - measured in MBytes/sec
2) Bandwidth - Measured in IOPS

These two measures are mutually linked ie 100MB/s can either be 1*IOPS*100MB, or 100*IOPS*1MB

The figures seem to also show a lot of cache effects, or have dubious provenance,  otherwise how does a USB connected drive achieve 2289.5 IOPS (how do you get .5 of an IOPS anyhow)

Hi Gerald,

I do understand there are several things to take into consideration when measuring the performance of any hard drive, however going into depth in so far as eliminating cache effects would go beyond the scope of what this article is attempting to achieve. You may have also noticed that I didn't mention or talk about the effect FSB speeds can have on a hard drive's performance either?

As I mentioned at the start of the article;
The reason you might want to skip the QD32 tests is that they're not particularly useful for real life scenarios and just take additional time to run. QD stands for "Queue Depth" so the software also measures "separate thread" transfer speeds. Information not of much use for our purposes. I only include the results that I got below for the sake of completeness.
I think the general flow of the article from that point forward clearly shows it is targeting beginners to hard disk performance measuring and not representing any type of advanced hard drive performance analysis.  
The figures seem to also show a lot of cache effects, or have dubious provenance, otherwise how does a USB connected drive achieve 2289.5 IOPS (how do you get .5 of an IOPS anyhow)

Indeed.  How do you get a .5 of an IOPS ?  

Or even a .7 or .8  

How about you tell us?  :-)

Thanks for your feedback.  Always great to hear back from ones readers.

Best regards,
Andrew

Hi

Can someone give me the CLI cmd to shutdown a HP MSA 2040

Thanks

We have a 4 usb external hard drives need to connect them to our PC.  We have a usb hub with no ac adapter.  We were told that since there is no ac adapter on the usb hub, the small electricity supplied to the hub will nit suffice to power all the drives.

Our notebook has a USB which supply power.  We can power down the notebook and connect a phone to the usb port and it will charge.

Question, if we use a non-ac usb hub and connect it to the power usb of the notebook, will it be the equivalent of a ac-usb hub?

Please advice.

Hi All,

I got the below important VM that cannot be down, during the migration (Exchange server) setup as MBR - NTFS.

it is currently running very low on disk space about 1.945 TB, how much more I can extend it from the vSphere level and from the Windows Disk Management level without breaking it or causing it to go offline ?
MBR-NTFS

I need to know what;s the exact safest limit to extend this disk.

Thanks,

Hi there, I have a MacBook Air that was written off after having water spilt on it. I suspect the SSD hard drive is OK and I want to try and recover the data off it. I have searched the net and found plenty of adaptors for connecting earlier mac dives (2012, 2013 ect) but the interface is different for the 2015 drive.

Does anyone know what this drive interface is called and an adaptor I can use to connect it to another computer (Prefer USB3) to recover the data? .

Hi,

How do i find the drives in my computer are locally attached or external harddrives or some nas or through IScsi  ?
Is there anyway to find out .

Thank you.

Recently my one and only 1 TB hard drive failed.  I bought a 2 TB hard drive to replace it and was able to restore my system via a Carbonite image.  

My confusion is that when I open "My Computer" and look at drive C:, its size is reported as  919 GB.  However, using the Disk Management tool tells me the following regarding healthy partitions:

78 MB, OEM partition

12.25 GB NTFS Recovery partition, system, active, primary partition

1850.69 GB NTFS OS (C: ) OS partition boot, page file, crash dump, primary partition


So what is actual size of drive C: ?  Is there any way to access the entire 2 TB of disk space?

(By the way, I am using Windows 7 Home Premium on a Dell XPS computer.)

What is a recommended software package I can use to test if an SSD drive is failing? Also, would prefer it to have a bootable cd or USB image.

I have used SpinRite and HDD regenerator in the past.

What do you all suggest I get?

We have several PCs that can write to an external HDD, but cannot connect to our network. These machines are locked down and we have no control over them. They save daily backups to external hard drives or flash drives. We would like to get those back ups on our network so that we don't have to manually move the HDD from the PC to the server in order to copy the data.

Is there a way to use a device of some sort that would act as an external HDD, but that has network ability?

PC -->HDD (via USB) -->??Device?? -->Network. That way we can pick up the backup from the HDD through the network.

I looked into Pogoplug, but they are defunct. NAS would work if it had a USB type B port (or micro) that would allow data to be written via USB. All of the NAS' I have found so far that have USB have the type A port that is not designed as an input.

Hi guys,

Scenario:
Dell blade server which has smoke damage due to a fire in the building.
HDD's SATA seem ok.
VMware ESXi

Aim is to get the VM's out.

Is there a way to recover a Raid 10 array of 6 hard drivers, BUT i only have the ability to see one HDD at a time via a PC (maybe I will need some raid recovery software).  I have a dual bay SATA caddy that I intend on using.

Any suggestions people?  Any other ideas?

Many Thanks.

I rebooted our file server which is a 2008R2 used only for file services.  There were two Microsoft updates one of which was a service pack update.  It has now been close to two hours and on the screen it still says that it is shutting down.  The blue circle to the left of the text is solid and not spinning.  It has (8) 2 TB hard drives in a RAID 5 array and the last drive is blinking steady green with no other activity.  My question is: Is it possibly still doing something or is it locked up?  I don't know whether I should force another restart or not. Any thoughts?

I have a LSI SAS 3000 1068E SAS PCI Card... It's used for our tape changer... Recently it started to get an error "The device cannot start code 10" on the device's general tab.  We even tried a new card and same thing...  We are running Windows 2008 R2.  I searched for a new new driver but no luck.  What should we try?

Hello everyone,

I have an IBM DS3524 on which one of the logical drive size threshold has exceeded.
I have freed up some space but the alert is still there and the consumed capacity is incorrect.

Is there a way to force it to refresh ? I have searched but I did not managed to find any solution.

Thanks in advance for your help,

Hi,

I bought HP DL380-G4 server from eBay and it seems to work but I'm having problems installing Win 2003 OS- I've 6-hd @ 146 GB/ - I created the RAID containers- 2-RAID-1 and 3-RAID-5.  I tried to separate 6th had as a spare but I unsuccessful or couldn't figure out how to-?
This is my home network- lab I want to practice with it before joining the server team in a month or so.  
I tried to run SmartStart 8.70B for x64 and booted to the CD but it ran for a good 5-7 minutes loading but then I was left with a HP screen and no activity. So I decided the power down the server.
Windows is not able to see the hard drives? What am I missing here?

I have a  EMC VNX 5300 storage.i connect 4 new servers to the storage and now want to assign the LUNS to the servers.
 i found that there are 3 storage pools already configured with RAID 1/0 and some of the servers are connected to this storage pool.
now i want to create a new storage pool with RAID 5 but when i create a new storage pool it automatically add x number of disks to the storage pool.

q#1 i am scared that if i will create a new storage pool then it will not disturb the other storage pools (RAID 1/0) which are already configured.
q#2 i found that 18T RAW disk space free .how can i use this RAW disk space to create a new storage group and assign all the new LUNS from this storage Group

Hi All,

Can anyone here please share some explanation and the comments on my Lefthand P4300G2 Storage array warning alarm?
LUN Utilization

Event: EID_RECLAMATION_THRESHOLD_STATUS_SOFT E00020401
Severity: Warning
Component: SAN/iQ
Object Type: Cluster

The cluster 'PROD.CLUSTER.2.1' is becoming full.  The cluster 'PROD.CLUSTER.2.1' Space Reclamation value is at 94.13% of capacity.  This value exceeds 90.00%. When the cluster exceeds the Space Reclamation limit, the application writes to thinly provisioned volumes in this cluster may fail, and other tasks that require cluster space may be impacted. Some actions to reduce capacity utilization on the SAN are to delete volumes and snapshots, reduce snapshot retention, add nodes to the storage cluster, use thinly provisioned volumes, move volumes to other clusters, etc.

Open in new window


I have created RAID10 LUN and maximize it as 11.5 TB VMware VMFS in the production environment but I'm worried about the above alarm if it is safe to continue or not?

Any help and comment would be greatly appreciated.

Thanks.

Hi, I have a small 3 user setup, we had an sbs server that got ransomware. We've restored the backup.
But I would like to look at removing a windows server from the network and move to a NAS that syncs in both directions with dropbox.
We aren't heavy users, but require local and remote access to the basic data.

Does anyone know of a NAS that will sync in both direction and not just do the NAS backup to dropbox ?

thanks for your time.

Dear Experts,

I changed my laptop's ProBook 4230s from SATA to SSD.

Now it gives me the 3F0 error.

Any idea how I can resolve this?
