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.

Connecting ESX Host to SAN switches.

I would like to know how you set up SAN Switch for ESX Hosts. I believe the VLAN where the ESX hosts are on, for instance VLAN 10, should also exist on SAN switch.
How do you configure SAN switch (Cisco) for each VLAN matching the VLANs on ESX Hosts. I have heard about Zoning, then heard about the recommendation  to have ESX Hosts in each VLAN map to the same VLAN on SAN switch. Now it  is like I am confused which one should be done? Zoning or VLAN to VLAN mapping, or they are 2 different tasks?

Thank you

We have a legacy ESX 5.1 cluster that has a 2TB disk limit. We are approaching situations on file servers
where we need to go beyond that. We're looking at disk pooling and disk spanning to do so. Which technique
is considered to be safest?? OS is Win2k12 R2.

Windows 10 Pro index options window is frozen. I got hit with some bug but I'm unsure what it was, it mostly affected my windows explorer functionality. I've ran the latest malwarebytes (3x after reboots) and selectively removed everything that I know wasn't mine. Explore.exe works for the most part but sometimes it is just blank and in task manager ONLY allows the restart option, indicating its busted. It only seems half busted, because if I navigate to a dir via shortcut it works fine. Another symptom is that not all filetype icons work in folders. Initially, none worked. Slowly some have restored themselves. I'll get to rebuilding that later since right now other things have priority.

I'm having trouble finding reports of similar issues to help me troubleshoot this. When I open Indexing Options, the container opens up but stays frozen saying "waiting to receive indexing status" and will not show any locations to index. I have 3 drives, one SSD for boot and two for storage. It won't allow clicking Advanced Options or closure of the container, short of ending the task via task manager.

I successfully ran chkdsk and sfc but no errors were found or corrected.

Other than that... I've never fixed this kind of issue before having never experienced it.
Have an old 2950 dell server and it has gone done, the raid error is reading -Raid Status offline. Would like to know if there is any way of bringing the system back online. below are screen shots. Thank you.

Server: HP ProLiant DL360e Generation 8
RAID Controller: Dynamic Smart Array B320i RAID Controller
RAID Configuration: RAID-1 (2x1TB drives)

Ubuntu 16.04 <or> Ubuntu 14.04

Hi All,
I am trying to install Ubuntu Server on the HP ProLiant, but even thought I set up the RAID configuration during the Pre-boot, the Ubuntu setup does not show that any drives are detected.  *See attached screenshot*.
I will also note that I am NOT a Linux guy.  But in the Windows world, if you can't see the drives it's because the driver for the RAID controller is missing.  The fix is getting the driver from the manufacturer website, put it on a USB, and boom.  But I'm having difficulty trying to determine if that's the exact issue and how to obtain the right drivers for Linux.  Am I even on the right track?

Any help would be greatly appreciated!
At our small Catholic school we are looking to utilize Network Attached Storage for  backup of our server. We have two building, one where the server resides and the other where we would install the NAS device. We don't need anything really fancy and 2TB would be sufficient or several years to come. What I am looking for is suggestions on what equipment to buy keeping in mind our budget is fairly limited and we need something simple to setup and maintain.

Thank you

On a Dell PowerEdge T110, shipped in Nov, 2011, we have this 1 of 4 hard drive with predicted failure.  It's set up as RAID 6, I think I saw (no spares... but raid 6 you can lose 2 drives before failure? Not that I want to get to that : )


Replace the drive? Right away?  You can wait? Any indication of failure predicted today vs. next month vs.....
If you are going to replace the drive, I thought I heard that you have to get it from Dell? They build / built? their systems to require dell branded hard drives to work?
Where do you get a drive like that from? I don't see it on the dell website?

Or is this the argument to replace the server?  1 of 4 drives failing.... the others are as old, the whole machine is 6 years old (SBS 2011 standard OS)
Our customer has very old backups, 20 or more years.
Those where done with WINRAR and winzip of those days.

there are two issues.
1. Are we able to read those formats today ? Or are we supposed to, lets say, every 5 years convert those backup files to latest formats?
    Is there any software that will do that for us automatically? Auto update itself and auto migrate the backup files to the new format ?

2. The second point is the storage device, usb connections improve they get faster and better, devices need drivers updated, according to new versions of OS
    So I guess we have no choice than to move all every 5 years to new devices ?

 HOw reliable would it be if we store in the Cloud? and is it advisable only the cloud ?
How are companies doing this around the world ?
I've been having a hard time with this for several days, hoping someone can help me with this.  

Here's the setup; got some Optane P4800X PCIe drives and I want to RAID the boot drive in Server 2016 for resiliency.   From what I understand hardware RAIDing PCIe drives simply doesn't exist yet, so we're stuck with software RAID.  Here's where it gets fun.  

I can RAID 1 the C: volume just fine.  That's all dandy.  But when I remove the primary plex, the secondary doesn't boot.  I have tried all sorts of methods to get the secondary drive bootable, including;

  • DISKPART and XCOPY the EFI and Recovery partitions from the main drive- no dice, BCD error
  • This
  • handy document was looking promising, but when trying to rebuild the secondary BCD we have no ramdisk entry in Server 2016, so that ended up a bust.
  • Fresh install of Server 2016 to establish a good Recovery and EFI partition, then delete the OS partition and replace it with a mirror- no dice, BCD error

All the fun of this points back to the BCD.  Problem is, I can't edit the BCD in recovery mode since the disk is showing up as foreign because it's dynamic (required to do MS mirroring).  If I import it, it instantly becomes unbootable.  Bootrec /scanos

I need to upgrade my HDD's for my physical server due to space restrictions on the original HDD's.  It is running Server 2008 R2 Standard and the Raid Controller is a PERC H710.  Is it possible to do this by simply removing one HDD at a time, letting the VD rebuild until all of the HDD's have been replaced and then expanding the VD?

We are looking for an alternative to SharePoint Foundation 2010 which is coming to end of life.
There is the possibility to move to Foundation 2013 (still free), but this also has only a few years of life left.

There are a confusing amount of possible alternatives out there and before I start sifting through them I thought I would ask the Experts what they thought.
We are happy to have either a cloud based or on premise solution and although what we have now is free we would be prepared to pay a little for something that has wow appeal.

We are a construction company and use SharePoint as a document store, photo gallery and very basic workflow (question/answer lists) for each of the 5 - 10 projects we are working on. What we like most is it is storage with meta data (who posted, who modified, when and various custom columns we have created) much more useful than just storing in folders as we did in the past. More document management than collaboration.

Our Intranet (only AD users are ever likely to to use it) needs are:

1. Storage for Word, Excel, PDF files with meta data we can add (Who, When, Where, Custom Columns etc), and batch upload/download.
2. Very simple Workflow. An uploaded or emailed document sits there until it has been actioned, after which it becomes easily identifiable as complete.
3. Photo Gallery - Single or multiple uploads, Albums, Thumbnail views, Auto Date stamping, Indexing.
4. Custom permissions on each site and within each site for …
Hello all,
Last night Veeam Backup Job has given an error for a virtual machine. When I looked at this virtual machine in the morning, I saw that it was closed because there was no space on the hard disk (retry / ignore screen). however, there was enough free disk space. At the same time, Veeam could not delete the temporary snapshot that it created for this virtual machine.
for this reason the virtual machine needed disk consolidation.
I increased the disk size through the storage and I could open the virtual machine.
then I started the consolidation for the virtual machine with vSphere. but every time I got this error. "an error occurred while consolidating disks: 5 (input / output error)

I shut down the virtual machine and tried again.
I manually deleted the temporary snapshot, my attempt failed.
I tried to manually take the snopshot and it failed.
I manually deleted the SnapShot that I took manually and tried again.

how can I get rid of this situation? I really need help. because in this case the virtual machine is over-consuming hard disk. Today I made a 100GB disk increase in total, but it quickly consumed this space too.
Thank you in advance for your support.

My Dell Poweredge R720 uses the PERC H710P Mini BIOS config utility 4.03-0002 and has been running RHEL 6 on a RAID1 array (Made up of 2 3TB WD SAS HDs). I installed 2 more SATA drives today as a separate RAID1 array (With the intent of using dd to clone my older drivers to these new drives), and now RHEL6 on my original RAID array won't boot. In the RAID utility, they show up as unconfigured physical disks, and my new ones show up as the new virtual disk 0. I couldn't see anywhere to tell the utility that I still need my old drives to be the primary virtual disk/boot device... Thanks in advance for your time.
I imagine encrypting server drives would slow down RAID. But what happens if a drive fails and needs to be replaced?
Will the encryption allow hard drive replacement?
Are there any other problems with encrypting Windows servers?
Just recently replaced a failing Server 2003 server with a Buffalo NAS unit running Server 2012 Storage Server R2 - this is a small shop so this unit is working nicely so far with the following exception.

Transferred files off the Server 2003 box onto a NAS share and all operations are functioning properly for all users.....EXCEPT 2 MAC users who access files off a share setup for these MAC users to work with. When these users browse the Window share using "Finder" - they do the initial connect fine. The drive is mounted and an alias is setup on their desktop. All the files will display in the share for a few seconds..and then the file share window will do a refresh...and all the files disappear. The files are still on the share..they just disappear from the MAC view. It's the oddest issue. No problem for any of the Window users...just happening to these 2 MAC users.

My last effort today was to add the username/password these MAC users use when they log onto their MAC systems (they don't have to put in the password..the MAC's boot straight to a desktop after a restart/power-up) - I added these same username/password to the "Local Users and Groups" on the Server 2012 - re-propagated permissions on the share...still no go.

Looking for a life-line as I'm out of

I have a Norco RPC-4216 server case (I know cheap as you can get) but I have an Areca RAID Card in it and the RAID Card reports every once in a while that an entire enclosure is getting dismounted. This is causing database corruption and the server ceases to run reliably and reboots until I recreate the database
See attached Picture.

Do you think this could be back plane related. I have replaced the RAID card with a brand new one even a different model Areca Card (updated card) and it seems to be the same problem I had with the first.

Any help is greatly appreciated.

Dear Experts, we tested this concept: but did not see the difference in backup speed.

Test1: We backed up a Mail Exchange server (VM) with VM snapshot:

Test2: With Storage backup

but the result was not so different

I believed Test2 should have quicker time (based on the article's suggestion)? Could you please explain and suggest? Many thanks as always!

Hi Experts,

       I am working on an web application (wagtail cms) like django-cms, which is in aws ubuntu.  Its backend is postgres, with elastic search few modules reactjs and nodejs.
The application is deployed in docker containers.  uwsgi is the upstream server for nginx.

      I get lots of errors with npm build, i am not able to run the application.  sometimes ports are not accessible. postgres is using 5432, elasticsearch is 9200. react is rendering on 9009. I get lots of dependencies error.    At what situation I have to use dockers?  sometimes I get errors in nginx configuration. could please tell what is good practice for npm build, run deploy.  

    What is the best way to architect the development and test environment?

    Will I be able access the postgresql, elastic search and nginx in linux ubuntu on aws with cms source code and contents on windows local pc?   or having the copy of postgresql, elastic search, cms contents and nginx all on a windows pc as development environment environment.   Elastic search has huge data.  and how to deploy the application on dockers in linux environment.

    What is the best way to have a development environment?  what is best test environment

   could you please tell me on how elastic search data is stored on postgres and what is network host setting in elastic search how it accessed from outside application.

    Could you please throw light on how to create development and test environment.

I have a VMware ESXi lab in my home using two physical hosts and a Synology NAS device. I've been using this for some years now without issue.  I am setting up a newer lab on two ESXi "hosts" that I'm running on my Mac using VMware Fusion. I set this up the other day and created the VCA on the Synology datastore and it was working just fine.  The only issue I had was speed since my Mac and the two new hosts are living in one part of my house and the Synology device is in the basement connected by a wireless network. While it ran OK, it was obviously a little slow and I decided to move the Synology box to the GB connection near my Mac. There is no routing going on here... it's all one big happy network and the wireless devices just create a mesh network to connect everything together in my house.

Before I moved the Synology box, I noticed that I was woefully behind on my updates so I applied all of the waiting updates. I didn't notice what version of DSM I was on before I started, but I'm on 6.1 now. After I did that and moved the box, I fired everything back up on the new lab and that's when the problems began. The hosts recognize the iSCSI setup and it sees the Synology device and the Synology device sees the iSCSI connections from the lab, but it no longer sees the datastore. I've tried doing everything i can think of in the ESXi environment to get the datastore back and nothing works.  I even took the box back to the basement and fired up the old lab and it also fails …
Starting clean with an external TimeMachine drive that's full

I have multiple TimeMachine drives and found I get informed when older backups are deleted. I like that. But today, I was told the disk is full and can not do the backup.

I did move my machine to a new MacBook, then back to my old MacBook, so it is trying to do a 312GB backup. Those are likely files it already has, but from a different machine ID.

How do I simply start over with that drive?
