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.

I'm looking for a bigger SSD for my current desktop setup and I'm finding the pricing all over the place.  It appears to be tied to the read, write and IOPS speeds.

My question is will I be able to notice and IOPS difference of 10-20k or a read/write difference of 50MB?

I'm trying to decide if spending and extra $100-$200 is worth it.  I know my hard drives are biggest bottleneck on the machine, so looking for suggestions.

Current Drive I'm looking at: https://www.newegg.com/Product/Product.aspx?Item=N82E16820147361

Any better suggestions welcome as well.

I have an old PowerEdge 1900 that has a Perc 5/i in it.  I go into the configuration utility and select RAID5 for setup.  I have 4 750gb hard drives, so it comes out to 2.2 tb, or close to it.  I initialize the disk and when that is done I step through the rest of the process and on the last page I select "APPLY" then CTRL+ALT+DEL to reboot.  Upon rebooting there is a message that says "All of the disks from your previous configuration are gone".  It tells me that there are 0 logical drives on the host adapter, and obviously, 0 logical drives handled by BIOS.  What is the issue?

I have purchased plenty of external drives and never had a problem making them work with Time Machine. Until now.

I pleaded in the drive, selected "Encrypt", added the password...

I was then told it would delete everything on the disk and said OK.

Then, it generated an error.

When I insert the drive get the attached error:

Disk error
What shall I do next?

Thanks

(Disclaimer: I'm not an Oracle expert, I'm a sysadmin assisting our DBAs with this issue)

So this is a real head scratcher.  We're rebuilding an Oracle analysis cluster after a major storage hardware failure.  There's a shared staging iSCSI mount that's set up to be shared between all the compute nodes and set up through multipath/ASM as an OCFS2 partition.  When we attempt to load the previous backups from the staging partition, we get the following error:

The head scratcher is that:

1. We attempted this with one of the backups and it failed, so we ended up making our own test dump file to further test to make sure it wasn't the backup file that was bad.

2. This error ONLY when loading files from the OCFS2 partition.  I set up a second iSCSI share that was just formatted as ext4 and impdp loads the dump file just fine.

3. We've deleted and recreated the OCFS2 partition with several different cluster sizes and whatnot and we always get the same error back.

4. I can read and write to the filesystem on the staging partition just fine.

File permissions are as follows:

-rw-r----- 1 oracle oinstall 184320 Jul 13 10:17 TEST.DMP

System is Oracle Linux 6.8 (clone of RHEL/Centos)

Any ideas...?

I have an HP MSA 2040 and I just inserted a replacement drive and I want to start the rebuild.  I know it's supposed to be automatic, but is there a way to manually start the rebuild and is there a way to monitor the rebuild?

Thanks

what is the best was to ensure that you get the correct component needed for a machine?

i typically need to replace or upgrade RAM, hard drives and display screens.

i have used cruicial.com for RAM and hard drives as the side has a scan feature but was told that isnt a great idea for security reasons.

i mainly work on windows machines (running win 10 pro) but also work on some imacs

This drive clicks constantly, about once every two seconds. I am suspecting a driver problem as

a. the drive checks out as being sound
b. the problem doesn't happen when it's being used under Linux

Any suggestions?

I typically configured my spinning hard drives for the OS and Data files as Raid 1. If something happened then I just swapped out the drive and kept working.

When I got the SSD drive for the OS I could only afford the one drive. Now the prices have come down and I was thinking of again using Raid 1, for availability.

Talking with Samsung Tech Support they said that it would work but that they don't recommend it due to the fact that it would shorten the life of the SSD.

Having just had the drive fail and while waiting for the replacement I am thinking of getting my system up with a new SSD and when the replacement ships putting it in a Raid 1 set.

Recommendations?

Thanks,

Steve

Hi All,

I'm using HPE Lefthand P4530 G2. My current free unused disk space on the array is 1600 GB, since I'm using RAID-10 (2-way) so effectively it is just 800 GB available.

Since my backup software using Storage Array Snapshot as per this article: https://helpcenter.veeam.com/docs/backup/vsphere/backup_from_storage_snapshots_hiw_hp.html?ver=95

Therefore based on this discussion: https://forums.veeam.com/veeam-backup-replication-f2/lefthand-snapshots-t20207.html

I have been told by the support team to use Thin LUN to utilize the Storage Snapshot with less disk space usage.

My current LUN for all VMware VMs are on Thick LUNs to avoid over-provisioning, so what're the steps to convert it back to Thin LUN with no data loss?

Does the converted LUN will be reduced in size or will it be at the same capacity as it is now?

Hi All,

I've got QNAP iSCSI LUN that is presented as 46 TB NTFS LUN, it is intermittently causing data corruption hence it is quite annoying for me to delete all backup job and then starting it again from the beginning.

When I run the CHKDSK on my existing backup repository, I got this error below:

People,

Due to Veeam backup requirement for the Storage Array snapshot on my HPE Lefthand, I can only use Thin Provisioned LUN for my VMFS datastore and thin VMDK (All thin).

So how do I set the monitoring system to email me when certain threshold is reached ?

I need to prevent the free disk space to become 0% to avoid the LUN becoming read only.

Is there any way to do it on the ESXi level as well to know about the Thin LUN provisioned space ?

Thanks in advance.

I've been tasked with disabling access to USB storage devices - not just denying access, but keeping the devices from being recognized and assigned a drive letter - on computers in a domain.  I've already set the Start value to '4' for the USBSTOR service and used file system restrictions to change the access of all users to 'Deny.'  But still, if a device is new to the system, it assigns it a driver and resets the Start value in the registry to '3' until the machine is restarted.  What am I missing here?

Looking for a article that give a understanding in the main hardware of a computer (processor i5/i7-hard drive sata/ssd) so I can make the right choice type of computers to buy depending on its use.

For example I need now a computer for a client that uses heavy outlook downloading from multiple accounts total around hundred emails per day. QB thy have on their server 75 company files and the users switch consently between files heavy printing and scanning and other light applications I was planing to go with a i5 but wondering if will be enough.

Hello and Good Evening Everyone,

          A coworker and good friend gave to me a Seagate 1TB Backup Plus Portable Drive.  Unfortunately, there was not any cables that came with it which brings me to this forthcoming question.  What will be needed to interface this portable drive to my laptop?  

           Any suggestions will be greatly appreciated.

           Thank you

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

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.

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? .
