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.

Dear Experts,

I am a new starter to a job, and have been given an initial project to work on that I'm hoping that you can help with.

The customer has an ageing archiving solution with SAN storage that archives email from their MS Exchange platform. There is a separate project that is almost complete that will replace the solution.

I have been given the task of overseeing the decommissioning of the SAN storage.

The customer believes that the only solution using the SAN storage was the legacy email archiver, but cannot be 100% sure that other applications haven't developed dependencies on the SAN storage during it's lifespan, and I've been asked to perform some due dilligence on the SAN to try an identify any unexpected connectivity.

My initial thoughts are to run something like WireShark on that network segement to identify any traffic with the SAN IP as a destination.

Is that the right approach?

If not, what do you recommend?

If it is, could you give me some guidance on how what config I should put into Wireshark to help me see the right results?

Many thanks in advance.

Newly released Acronis True Image 2019

In announcing the release of the 15th Anniversary Edition of Acronis True Image 2019, the company revealed that its artificial intelligence-based anti-ransomware technology – stopped more than 200,000 ransomware attacks on 150,000 customers last year.

Hi Experts,

This morning we conducted a high availability test on our virtual infrastructure. We have 2 esxi 6.0 hosts connected to a dell md3400 direct attached storage. When our esxi host was shutdown the HA worked fine, but the LUN from the storage was gone.

All looks well on the Storage Array itself, the host is in the group and LUN and port identifiers for the host appear to be fine on the MD3400. On the host the PCI storage adapter is there, but no storage.

I did a re-scan on the host and rebooted the host again and still no storage.

Thank you

We are trying to migrate from vCenter 5.1 to vCenter 6.7.  We will create a new vCenter 6.7 environment with 6.7 ESXi hosts. The best way to move VM to the newly built VMware vCenter 6.7 environment is to -

1. Share storage between ESXi 5.1 and ESXi 6.7 hosts.
2. Do storage vMotion to the newly shared storage.
3. Register the VM in vCenter 6.7 console.

However, we have a major problem with sharing storage between ESXi 5.1 and ESXi 6.7 because of some compatibility issues.

I heard that we can do this with a VMware tool. Can you please help me with that tool name?

Or is there any best approach to migrate VM considering our situation?

Hi,
I am using ESXi 6.0 cluster with few hosts.
I need to umount/detach datastores related to an old storage that should be removed from datacenter.
Basically I am following this:
https://kb.vmware.com/s/article/2004605

While umounting specific lun from one specific host, I encountered a waring message (like this lun is used somewhere).

I noticed a VM which seems to have references to such datastore:

lun
storage1 lun 9 and storage2 lun 1 are definitely empty.

I suspect this could be related to some previous snapshot, but I am not sure.

How can I "force" the umount in that case?

Thank you!

Hi

I’ve had two PC’s have an issue where I get the error
From the RAID controller:

RAID -foreign configuration found all drives lost.

The 1st time, not being familiar with the error. I gave the user a new PC, thinking the HD failed.

The 2nd time, I imported the foreign configuration and all seems well.

So my basic question is, does the error:

RAID -foreign configuration found-all drives gone


Mean the drives or controller is failing or unreliable or something else?


Any insight into this issue would be greatly appreciated


Thank you

Hi I wanted to use software mirroring to mirror a Windows 10 drive, system actually.  I'm going to use like a 250 ssd, don't think that matters.

I know the older version of windows didn't let you software mirror unless you had Ultimate, or maybee Pro.  

Question, Windows 10, what version comes with the mirroring capability.

Amazon Web Services

Are you thinking about creating an Amazon Web Services account for your business? Not sure where to start? In this course you’ll get an overview of the history of AWS and take a tour of their user interface.

Do usb storage devices have any sort of internal clock on the device itself, or do the date modified/accessed/created dates shown on files stored on the device get populated by the PC's they have been plugged into?

We use Office 365 for office email and Dropbox/Egnyte for shared file storage.
When a user leaves the company, I want to be able to easily access/search their email but I do not want to maintain their account indefinitely.
I also do not want to maintain multiple 2 to 10 GB PST files.

I am looking at using Migrationwiz to migrate old employee O365 accounts to a single O365 account under a shared email account (I.E. xstaff@somecompany.com).
This would also allow me to set their email addresses as an alias on the shared account.

Does anyone have a better solution?

I have several Network Attached Storage (NAS) devices on my network which all support iSCSI.

How can I setup Microsoft Data Protection Manager to backup to one of these NAS devices? Can this be done by installing and using iSCSI Target Server?

Or can I do this by creating a virtual VHDX disk that is stored on the network share of this NAS?

I understand this will probably take special configuration within Server 2016 to connect to the NAS device using iSCSI and I am hoping to get all the steps on how to do this.

I am using Veeam 9.5 and a Quantum iScaler i40.  I was wondering if anyone had connected one of those to a Veeam server and if yes, how?

I can get Veeam to "see" the drives in the iScaler, but not the iScaler itself.  Veeam can "see" the drives, but when I try to inventory a tape, I get an I/O error.  I'm thinking I need to load up the iScaler itself, rather than the drives.

Anyone work with these at all?

Thanks

I purchased a "YK838 - RAID Controller PCI-E SAS 2-Channel SAS6/IR PowerEdge R510 by Dell."

The Amazon URL of where I purchased this adapter from is here.

What kind of cable adapters will I need that will allow me to connect two Serial Attached SCSI (SAS) hard drives to this PCI controller card?

For enabling mail archiving on Exchange 2010, can we prevent user to delete any emails on the archiving storage ?

Alternatively, is there any better way if we want to ensure that we need to keep emails for at least 7 years ?  Is there any size limitation for the archiving mailbox ?

Thx

Exchange 2010 has been enabled for archiving mail on another server. What kinds of storage device is normally used to save this archiving mailbox ? Should we use RAID-6 Dell storage ? What sort of backup does we normally use to backup this storage ? Main consideration criteria is cost saving.

I have two disks in Predictive Failure on a Dell Poweredge C2100 (Using Open Manage 8.2). We got new SAS drives to hot swap in. I started with the Global Hot Swap (in Predictive Failure) and replaced it with the new drive.

At first it gave the Green Check Mark, "ready" and i could assign it to the Global Hot Swap in the Physical Disks Section but got the attached Caution message. It still allowed me to assign it as a hot swap but was not being recognized as a virtual Disk in the Raid Array. Prior to swapping we could see disk 12 in it's own "Global Hot Swap" section under the other 11 disks in the array.

When i tried the "Create Virtual Disk" and "Assign/Unassign Global Hot Swap" options in Virtual Disks it would not show up as an disk i could select.

When i went back to the "Physical Disks" section the new drive is now showing as "Foreign" and i don't see an option to reconfigure it.

Help is very appreciated.

Hello I recently changed some GPO's at domain level, now when a HDD that's encrypted with BitLocker in plugged in we get a message that say's "Group Policy requires that for this drive to be writable, either  auto-unlock must be set or a smart card must be used.  A password alone is not sufficient."  Not sure what policy controls this, also on my DC running server 2016 when i click to unlock drive nothing happens.

Hi

I have a Dell R720XD running a Perc H710p raid card.

I am in the process of setting it up and want to ensure i can increase the raid capacity at some point down the line.  I have read the H710p user guide (attached) which states that if i use Raid 6 i can add more disks and do an online capacity expansion.

To make sure i have setup a Raid 6 using 4 x SAS drives.

I have then turned the server off and installed a further 4 x SAS drives (Same model and capacity).

When i then go into the raid config using either the OSMA or the CLI there is no reconfigure option or even tasks option as per the below link.

https://www.oxfordsbsguy.com/2017/11/26/how-to-expand-a-dell-perc-h710-raid-array/

The server and raid controller are running the latest bios versions.

I have also attached a screen shot of what i see in the OSMA.

Please help, thanks

Hi experts, one of our clients wants to setup file server clustering. DFS is not a route they want to pursue. They have an existing 2012 server (non R2) and they want to add another 2012 file server and setup clustering. Both servers are VMs setup on VMWare and they want to use the same shared storage from a Dell Equalogic SAN. Is this a good article to follow to set this up? - https://clusteringformeremortals.com/2012/12/31/windows-server-2012-clustering-step-by-step/ 

Also the change needs to be transparent to end users, will in the process of setting up clustering end users get disrupted? Currently there is a login bat script which maps the drive

All end user clients are still using Windows 7. Will the users notice if one the servers they are connected to goes down?

Thanks

Client's iPhone 8 was lost Friday night.  Soon after it was lost they got their iPad and put the iPhone in Lost Mode.  A few hours later, they found the iPhone.  It suffered major damage to the screen.  The screen is black and doesn't appear to be responsive to touch.  It was still online when Lost Mode was disabled on the iPad later that night.  Client upgraded their storage space from 50gbs iCloud (photos hadn't been backed up since June 4th, 2018 because there was no more iCloud storage space) to 200gb iCloud in the hopes that the phone would somehow connect to wifi and the photos would upload to the cloud.

Two days later the iPhone was connected to the client's macbook.  The device was recognized, but iTunes couldn't do anything else because it was still in lost mode.  I went on the iPad and tried to disable lost mode, but the program acted like it never put it in lost mode.  The iPhone was shown as offline now in Find My iPhone app.

I tried iMyFone software to see if I could recover the photos.  It won't get passed the step asking to trust the computer because the screen is unresponsive and the client's thumb on the home button isn't doing anything either.  iMyFone won't work.

The iPhone still makes noises when its connected to a computer and the home button still buzzes when pressed.  It appears to have battery life just fine.  I've tried restarting and hard reset, but doesn't appear nothing happens.

We are trying to recover the photos on the device.  Is …

We have cluster of vmware esxi 5.5 hosts and they are connected to HP LeftHand storages.
LeftHand storages are planned to be updated with the latest version.
Because there is a possibility storage update to failed,  and Lun presented from the storages to ESXi host to appear as not available, I was wondering is there anything(any advanced settings in esxi 5.5) that I can configure in esxi 5.5 so I can protect VMs in case of this scenario(PDL and APD). From v6 and above it is easy, we have a VMCP module and settings for PDL and APD down scenario, but what about version of esxi 5.5.
Could you recommend me something, or should I stay with the default settings of esxi5.5 hosts.
