Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Hi, I have a Dell PowerEdge R630 with 6 disks (2 virtual disks with 3 disks each, both RAID5). Controller is PERC H730P Mini
One of tray caddy is broken, and I need to replace it.
I could put disk in "fail" state and replace tray caddy.
Since I can afford a downtime, I wondering if I can simply shutdown server, extract disk, replace tray, and power on again.
Will controller raid "notice" anything?
Thank you!

I'm running a domain controller using windows 2008 r2 in a raid 1 setup. This morning it crashed and won;t startup past a cursor on a black screen before crashing again. I've tried
 1 ,starting in safe mode  2) using redundant boot records 3)booting to second drive without any different result.
I then tried windows 2008 r2 install disc and repair computer option. No image was available. I then went to command prompt and tried SFC /scannow, I got error msg "A system repair is already pending..." I then tried "dism.exe /revertpendingactions" It tells me that ScratchDir may be too small to work, but I have atleast 3.5 gigs free on a 186gb SSD.

So now i'm stumped. Can someone give me a suggestion of what to do next?  Thanks

I have a Windows 2016 server and it is running Windows Server Backup on a multiple times a day schedule and dumping the files to a USB drive.  everything is working but what I am trying to figure out is this.  Most backup software will keep x amount of copies on the storage device than then start over writing the oldest FIFO.  There is no way to tell WSB to do this so does it just run until the USB drive is full then crap out or does it run until full then start over writing?

Thanks

I would like to ask about the HDD which are currently will be use as external drive and in the future will used to NAS.
I saw that some HDDs has the spec : for nas 8-16 NAS storage and some other HDDs for nas 1-16 NAS storage ( this is coming from their description)

I don't understand what is the different?
Can i use  a hdd  which is build for NAS 8-16 with only 4 bay nas ?
what else is mean?

Short description: Dell PowerEdge T300 logical drives keep disappearing about an hour or two after boot!

I've got a Dell Poweredge T300 server with 20GB RAM, 1.50TB storage, and running Small Business Server SBS 2011. The main function of this server is handling Exchange 2010. Roughly 1 to 2 hours after boot the server slowly begins to crash.

At first it looked like the SQL server database was full and something was possibly swamping the processes causing the server to freeze. While watching the disk accesses in the Resource Monitor I saw that the logical drives (C: and E:) would suddenly disappear . Once that happened all functions on the server would slowly crash and I would have to do a hard reboot. The reboot would take about 20 minutes before I could get to the actual desktop to view the event logs, task manager and resource monitor. Everything would run like normal then after about an hour or two the crash process would happen all over again (e.g. - logical drives would disappear, explorer freeze, need to do hard reboot, etc.).

This led me to check the RAID controller (Dell SAS 6IR). At times it froze while I was trying to go through the menu options. Having dealt with this before with another Dell server I suspected that the RAID battery might be failing. Looking at Array SAS1068E it shows a status of Degraded and and 0% Syncd. As I type this I'm about to return to the office to confirm which physical drive has failed.

On Friday afternoon I got in touch …

Hi,

Parent and child processes are accessing same content from nfs share. based on some logic parent process deleted files which are already opened by child process. I think, it's internally created files which are .nfsxxxxxxx. These are with c++ application. Is there any settings or configuration to handle such issues to avoid .nfsxxxx files.

Thanks,

Recently a user brought an old WD MyPassport 2TB drive to me.  It is an external drive and has a double connector (it looks like the one in this video - https://www.blogtechtips.com/2016/10/27/how-to-open-a-western-digital-my-passport-external-hard-drive/).  When I connect it to a windows machine it just makes a grinding noise and does not appear anywhere.  The same is true when attaching to a Debian Linux distro.  I was going to take it apart as in the video, but when I got it apart I realized it could not be put into my drive bay, which would take any normal drive, but not one with that connector.

Does anyone have any ideas about how to get the data off of this?

Hi,

I was wondering if anyone can share a light on this,  have been asked to transfer/migrate Microsoft Stream Video files to Vimeo.

I have no experience in MS Stream or even where the videos files are stored but I presume would be in Sharepoint or Onedrive storage.

Thanks in advance

NFS on netapp filer - very slow only when over a hop


hi out of the blue. - juniper in the core  CIFS has slowed to crawl off a netapp - engineer did put a route in but only in prep for a change - it seems from that point on NFS browse to the netapp is soo slow its unusable
we since removed the route - but its just as bad no difference
dont even know if what he did was related

anyway if you are on the same subnet as the cifs netapp filer  (eg on a server in the same subnet )CIFS  performace is fine!!!
as soon as a hop to get to filer cifs share - its hopeless

Hi,

  I  tried to find the free space on mounted volume which is aws elastic filesystem. used statvfs api to find, but statvfs_obj.f_bavail and statvfs_obj.f_blocks are 13digit numbers, statvfs_obj.f_files and statvfs_obj.f_ffree are zeros.

  How to retrieve correct details from mounted aws efs on linux by using statvfs( mounted_filesys_path, &statvfs_struct_obj).  Th path looks like /mnt/efs_mounted_from_xx_city.

  OS: RHEL7.4,

  mount details:  nfs4, rw,relatime,vers=4.1,rsize=1048576,wsize=1048576,namlen=255,hard,noresvport,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=xxxx,local_lock=none,addr=xxxxx 0 0

In Azure I am creating a storage account, but need it to be accessible from our vNet's only.  During the Storage Account setup you can specify a vNet. The problem is we have two separate vNets in two different regions that needs access to this account. Instead of using vNet can we create a NSG for our Storage Account?

Hi,

My system volume\dedup\chunkstore\{... }.ddp\data path has grwon to over 1 Ter.
How can u go about cleaning up or limiting the Amount of space that the sys vol is allowed to use?

i had already set a limit on the size which shadow copies can grow to as also re-directed the location of the shadow copy for the drive in question to another drive.

I have an HP Proliant G8 server.  Dual 12 core AMD processors.  It has 94 GB of ram and 16TB of local storage.  I would like to  use this in our test lab.  I have attempted to install ESXi 6.5 update 2 (HPE build) to in installed internal thumb drive, using a external flash drive and a USB connected DVD drive.

I have rebuilt the flash drive twice, once using Yumi and once using Rufus pointing to the VMWare ISO file.
I have reburned the ISO image twice using ImaBurn.

In every case, the server boots without any errors, but indicates no bootable media available.

I have altered the boot device from internal to external USB and made sure it was enabled.

I have also altered the boot sequence to CDRom when trying it from the DVD player.

Never had this issue before.  Anyone have any idea.

Hello,

We have requirement to delete million of temp attachments from  windows server to ease up the storage space.
This attachment had been since in existence since 2014 - until as of date.

Can you please advise on the following points

a) To begin with we will be interested in going with 6 months delete from 2014 onwards. Once the six month
   delete is complete from 1-1-2014 - 6-30-2014, then afterwards we will proceed with next 6 months and so on.
   Approx count will be around 3 to 4 millions for every 6 months.
   We will be interested to proceed with phase delete instead of big bang delete as this is production environment.

b) Can you provide if there are any tools or command available to perform the above requirement.


Regards
Tom

I'm configuring a VMware vSAN  on a few Dell PowerEdge R720s with a PERC H710 Mini RAID Controller (embedded) running vSphere 6.5.  I'm trying to surface the drives (2 SSD and 6 HD) but there are restrictions on the H710 not allowing me to convert to non-RAID.  VMware documentation indicates that drives must be set up in a "pass through RAID" configuration.  So, do I get another RAID controller that allows for no-RAID drives or is there a way of creating Raid 0 drives or can I mirror the 2 SSDs (RAID 1) and RAID the other 6 HDs.  Maybe I'm old school but I tend to trust controller RAID more than software raid, but it's required so not sure I can get around it.

Hi,

We are having a new Dell ME4024SAN specced out and they have quoted for 10k SAS disks( 10x1.8 HDD 10k 512e SAS 12 2.5) and also they have added 2.62TB ssd for auto tiering.
If I go with 15k SAS dHardisk  and will it make noticeable speed difference.
Any  help much appreciated
Thanks

Hi

We are going to upgrade our UPS on site.

We currently have a single Eaton 5PX and Eaton 5130 UPS running our single and only cabinet at head office.  We recently had a power cut which flagged issues.  These are the run time & load on the 5px and also a battery warning message.  We would now like to increase the wattage and run time, along with managing the UPS and also shutting down our on-premises vmware hosts if required.

We also have 2x old managed APC PDUs.

We have worked out that we have c6000 watts to cover.  Rather than buying a N=1 UPS at a steep cost are we able to use two 5px 3000 eatons splitting the load across the dual powered devices (switches, storage and servers) and use the 5130 for non-critical systems.
Is this possible?

Would you also replace the APC PDUs for eatons, would we requires x2 and how best to configure?

Thanks

I have been trying to backup my Netgear ReadyNAS Duo to an external hard drive that is connected to my PC, using Syncback Free. AVG has reported many threats while Syncback is attempting to do the backup. Most of them include "SBS" in the name of the supposedly infected file. When I take a look in the location where the infected file is meant to be, I find sometimes that is not even there. For a PC that is regularly having AVG run full scans, it seems very odd that it would discover so many infected files as soon as I start a backup. Could it be that Syncback is generating files that are causing AVG to consider them to be malware?
Can anyone suggest what they think might be going on here?

Hi

I have been looking to replace our storage infrastructure. One of the IT companies suggested Fujitsu DX100 S4 would be suitable for our environment.

Please can you let me know a equivalent storage model in DELL and HP.

Thanks

Need to make a VM out of a CentOS 6 asterisk box with 3 500GB SATA drives in RAID 5.  This gives me a 1TB drive that has 42GB used.
After some googling, it looked easy to use "dd conv=sparse" but that produced a 1TB disk image.  I loaded the dive on /dev/loop0 and tired to use gparted to shrink it, but gparted said it need gpart to see inside and gparted was nowhere to be found.  (The disk image in on a Centos7 machines.)

I have used TestDisk on the image with a few different parameters but it always comes up with results that don't match fdisk -l on the original machine.  (I have attached the output.)

I was going to try Clonezilla next, but I thought I would ask some expert advise before wasting more time.

So, what is the best way to get a 1TB RAID 5 image with multiple partitions into a VirtualBox VM with only the 42G of data? (I would make a 60GB virtual drive anyway.) fisk-output.txt

We us NFS as our storage protocol and have seen very poor performance on our VM’s from time to time. On our SAN, the average latency is around 2 – 4ms which is ok. What I have observed is when our host our pegged at 95 – 100% CPU usage, our DAVG time goes up to 15 – 25ms. With that being said is the following state correct. With file level storage when the host is CPU constrained it will cause delays in the NFS calls to the SAN which in turn causes poor performance. In short, the CPU usage on the host has a direct result on NFS performance. This is not the case with block storage though correct?

Is it possible to have data stored on a Windows server and when it starts to fill up it overwrites the oldest data.  e.g. like a DVR.  We are looking into a surveillance system and they want to store the video data on a server.

Or is there a better way to store the data?  It will be streaming over the internet.

Hello,

We have standard virtual switch that has 2x40G fibre links that are a  portchannel and are tagged with  the ISCSI vlan on both the switch and the hypervisor ends. The San is connected to untagged ports on the same ISCSI vlan.  The San and the hypervisor internall settings have MTU of 9000. However, the physical switches between them  have MTUsettings of 9024 and 12000
 Is this likely to cause issues?

Are there any implications for a frame that starts at MTU 9000 untagged at the San end, and then has a vlan ID added to it?



Thank you!
