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.

I am creating a new Hyper-V setup. Host will hold two VMs. One DC and one RDS. I usually create three vhds; one for each machine and one vhd that I share for the data. When I try to connect my DC through the virtual SCSI controller and add a "shared drive" and point it to the virtual drive I created, I get an error that says, "The storage where the virtual hard disk is located does not support virtual hard disk sharing".

I know I have done it this way in older versions of Server. Is there a new proceduressharing.JPG?

I just purchased a HP ProLiant DL380 Gen10. I have 6 2.4TB drives configured with RAID10 ADM. When I load Windows, I only show I am getting just under 5TB. If my calculations are correct, shouldn't I get over 7?ILO RAID Config

I have 2 of Dell Server PowerEdge R 510.
Both have got Windows 2019 Server as the OS right now.
I have a SAN (Storage Area Network) which is Dell PowerVault MD 3200 (12@ SAS 600GB).
I installed the “MDSM” (management software Dell Modular Disk Storage Manager at each of R 510); accordingly, from both of the R 510, I can see the MD 3200.

The Goal: I want to create some virtual machines at both R 510 which get the storage from MD 3200.

Note: I do have a little knowledge of Dell Server and no experience in VM machines; I have recently worked with Dell servers; This forum has helped me a lot; something like, it is big challenges in installing Win Server 2019 at R 510 which is INSTALLED now at both R 510, ETC.

Question: How to configure the SAN so it can be linked to VM machines at R 510?

I have a Dell Precision desktop T5600.   The two HD drives are connected to SATA 0 and SATA 1 on the motherboard.   The DVD drives are connected to HDD0 and HDD1.   The DVD drives do not show up on F12 boot.   How can I set up the BIOS so they are detected?

Server#1(Dell R510): it is at 135 subnet
Server#2 (Dell R 510): it is at 135 subnet
The SAN (Dell MD 3200): it is at 135 subnet

Server#1, server#2 and MD 3200 are located  in the data center (Colo).

From Office (It is at different location with Colo), I can do the followings:
I can RDP to Server#1 (which from it, I can see “all network drives”),
I can install the Management software for the SAN (=Management Software Dell Modular Disk Storage Manager “MDSM”) at Server#1 remotely, then when I launch the MDSM, I can see the SAN (MD3200)

But from Server#2, I cannot see or connect to "any network drives"

Question: Why i can not see any network drives from Server#2?

I am trying to boot to the DVD drive in my Dell Precision T5600.   The drive is connected to HDD0 on the motherboard.   The hard drives are connected to the SATA 0 and SATA 1 respectively.   When I hit F12 on bootup, the DVD drive does not show up.Bootup ImageBIOS 1BIOS 2BIOS 3
Hi Folks,

I have a file, which I need to sort and segregate the Transaction sets and transfer each transaction set into an FTP folder as a separate file. PFA is the original file "file-a.txt", With the help of other experts in the community using the program "sortingMultiEDIrecords.txt" I am able to segregate the Transaction sets into multiple output files in my example it is "output-1.txt", "output-2.txt" and "output-3.txt". Then I used another program "ftpFileUpload.txt" to upload these output files into an FTP server in a specified folder.
            Now the issue I have is I am having trouble doing this 2 stage process in my server in which I will be deploying. So I am looking for one Java program which instead of genearting the output files into a folder and then picking it up from there to upload into FTP, I am looking a for a solution where in the outputs are directly FTPed in teh FTP server. So instead of the BusortingMultiEDIrecords.txtsortingMultiEDIrecords.txtftpFileUpload.txtfile-a.txtoutput-1.txtoutput-2.txtoutput-3.txtfferedWriter which writes to an intermediate storage should actually directly write it into the FTP folder. PFA all the programs and files. I would appreciate the feedback and sample code if possible.

I am setting up a lab environment following the basis on this article:

My question pertains to the NIC setup.

My Storage Arrays have only SFP+10 GB ports. My host machines have 4 One GB cards. Ideally I'd like 4 Ten GB SFP+ ports on the host machines - and I can obtain new NICs for them but would the heartbeat nic really need a 10GB connection? Obviously the storage NIC on the host would need 10GB SFP+ to communicate to the storage arrays - where the VMs will reside. Is there a way I can utilize some of the 1GB NIC cards for some of the 4 NICs (vEthernet, Production, Storage, Heartbeat) and 10GB for others and not have performance degredation? Which need to be on the 10GB connection to take advantage of performance?
My WD DL4100 NAS device has become inaccesible. I cant ping its ip address and it seems to be stuck in a power cycle loop. The disk 4 disks it contains are setup in a
RAID 5 configuration.

We have an identical NAS device that is being used for another purpose.

Would it be possible to simply move the disks in the broken device and put them in the other identical NAS. Would it then boot up and will I be abkle to access the data?

Any help would be appreciated.
We will be having PetaBytes of Data to store on Premise  in the immediate future and would like to know the best Object Storage in market today and how to evaluate them.

I'd like to install OSX Mojave onto a VM instance (VirtualBox) but am having a heck of a time getting it to work.  I've tried three different .rar files that have the Mojave image on them and have set up my settings correctly on that VM instance i.e. memory, storage, display, etc.  Does anyone have an easy and sure fire method of getting the OSX Mojave image onto VirtualBox?
I'm in the process of recommending a new server for a small office and would like some recommendations on storage.  Cost is rather critical here, so I'm wondering about cost-effective drive arrangements.

There are about 7 users in the office, basic file and print sharing, and an SQL server.  The SQL server is a primary application for them now, but that is getting moved to the cloud and will have very light use in the future.  The data and log file for the SQL application take up about 2G of disk space.

The server will be configured with Server 2019 as a host, with a VM for the DC (with DHCP and DNS), and a VM for file/print/SQL.

Their present disk use (single, non-VM Server 2012) is less than 250G total.

I'm looking at Dell, HP, and Lenovo servers.  Probably 16G of RAM, 8-core CPU, and 900G-1T of storage.

I'm trying to keep the cost down and storage is the issue.  I'm expecting to use RAID1, but am debating using a non-cached "FRAID" controller, using Windows to do the mirroring, or purchasing a PCIe RAID controller with RAM and battery backup.  In most cases, I'd always go with the last choice, but I'm wondering if the cost could be avoided here.

I've not decided between SATA, SAS. and SSD for the storage either.  Whatever I recommend will be enterprise-grade devices.

I don't have hard numbers at the moment, but the cost differences between the two different sets of choices are substantial, both in actual cost and in percentage of overall cost.

We have a Windows Server 2003 PC that has been fine until yesterday.

I noticed that the C Drive storage space on this server had gotten quite low.

I searched and found a large increase in size of folder "Projects" in "C:\Documents and Settings\All Users\Application Data\Microsoft\Search\Data\Applications\Windows".

It seems to have increased from about 1GB to 11GB.

I noticed yesterday after doing a search for large files on server, a file called "SystemIndex.Ntfy" incrementing in size every few seconds, located under above directory under "Projects/SystemIndex".

What could be the reason for the increase in size for these files?

How do we solve this issue?

Hi All,

I may be being silly here. I have a Windows Server 2016 which I am using for file sharing (testing purposes). I have created a share and mapped this share. I can see the shared folder in both the file and storage / shares part of server manager, and if I navigate to the folder via This PC.

As soon as I do anything with this share, ie create a folder etc, I cannot see what has been done either  accessing the drive directly via this pc (nor does the contents show up in command prompt via the dir command unless a specifically instruct it to view the directory. IE a dir of E: shows nothing but I can run E:\New Folder and it will navigate to the hidden folder but will not display its contents)). I see the Shares folder, but nothing within the shares folder. If however I browse via the shares control panel I can see the share and if I explore the share I can see everything I have created. I can also see it via any other machine that has mapped a drive to the share.

Is this a new feature of Windows 2016, or what am I missing? I thought maybe permissions, so I gave the shared folder everyone full control, but it is still hidden from within Windows.

Hi All

We currently have two virtualised Windows file servers. The first has a secondary Virtual hard disk attached (different datastore) that all of the shares are stored on. The second uses the iSSCSI initiator to connect to a volume directly on our SAN. All Volumes on the SAN for both servers are replicated to our dr site. Both servers are backed up using Veaam

I am currently planning one possibly two new file Servers as their replacement.

1. Which offers better performance, direct file shares on the virtual disk or the disk shares via the iSCSI initiator?
2. When Veam backs up the second server will it also back up the data or only the iSCSI initiator config? ie if I had to restore the server but the SAN volume with the datawasn’t available would the recovered server have a folder with data in it or a disconnected data drive?
3. In the event of a problem such as a ransomware attack which is better/ quicker to recover. A window share on a virtual hard disk backed up by Veeam or Windows share with an iSCSI back end from Veam/ SAN volume replication?
4 Which approach would be recommended?

I am trying to backup my FMC4500 to my SCP Server. I am running Windows 10 with SolarWinds SCP Server.

1. I have any/any on windows firewall
2. I can successfully SCP configs and backups from other devices (ASA's and Switches) to my SCP Server
3. I am trying to setup Remote Storage Device under System Configration. It will NOT successfully test.
4. I have tried running the backup and copying file remotely to SCP Server. The backup with run successfully, but the SCP copy will fail.

Hi, i am into a project where i need to setup a car auction or bidding system. Can someone tell me what equipment do i need and how it works in terms of hardware and software.
Hi all

I have a Dell Optiplex 3030 AIO PC running windows 10.

It is randomly blue screening with DRIVER IRQL NOT LESS OR EQUAL iaStorA.sys

I have made sure all the drivers are up to date as per the Dell and Intel website but its still occuring.

I have seen that apparently its to do with the intel rapid storage technology and to remove the software for this, but i cannot see any mention of this on the PC.  And i have also tired to install the latest version of this to which Intel said my hardware isnt compatible with this software.

any ideas?

I have an old 2008 R2 server that is hosting our 8 Hyper-V VMs and I'm looking to upgrade. Just need some sound advice since the landscape has changed a bit.

I want to have some redundancy of the VMs and if possible, run them off the flash based array we have connected to it (This server also shares the array storage to the rest of the network).

Was thinking about this simple solution, but can you provide feedback on what you think of the design?
2 identical servers running Windows Server 2019 (not sure which version would suffice)
Both run Hyper-V for load balancing but mostly for redundancy.
Also wanted to share our storage array (which is currently connected to my 1 server, but want to somehow connect it to these two new ones) to my end users.

Whenever I attempt to connect to the MD3200 Direct Attach Storage device using the PowerVault Modular Disk Storage Manager, I get the following on both nodes that can connect to it:

This storage array contains a RAID controller module you have not added.  You can launche its Array Management Window but any operations that must access the unknown RAID controller module will fail.  Use the Partially Managed Storage Arrays option to display the unknown RAID Controller module and add its appropriate host name or IP address.

The MD3200 shows as OPTIMAL and shows no alarms at all.  It has one disk pool that I can change the preferred path on at will with no problems.  

The Partially Managed Storage Arrays shows the following:

Hi, I’m after some advice on HyperV setup with SAN
We currently have one Proliant Gen10 running HyperV
The first two NICs are Teamed together and plugged into Vlan 1. (Host management network team)
Two further NICs are teamed together and used for the Virtual switch. (Virtual Machine Network Team).
All VMs are currently stored locally on the Server

We will be introducing a second Proliant Gen10 and a HP MSA2052 SAN
The goal is to move the VMs to the SAN and set up failover between the two Hyper V hosts.
Does the second Hyper V Host get setup the same as the first Hyper V Host?
(Host management network team) and (Virtual Machine Network Team) plugged into a switch(s).

Then connect both Hyper V hosts directly to the SAN using the ISCSI controller ports?, or do the ISCSI network ports on the HyperV hosts and the ISCSI ports on the SAN both plug back into the network switches?
If it’s the latter, do we still need the (Virtual Machine Network Team) ?

Some guides mention MGMT, are they referring to MGMT in respect of having access to the server for say ILO access, or are they referring to connecting them to the primary VLAN for normal data traffic

Kind regards
Just specing out a server, single host to run 4 VMs, Going with a Dell Poweredge Perc h 730p.   with 2 GB of RAM on the controller.  How much does the RAM on the controller really impact performance?  Nothing is tremendously I/O intensive.  Would there be a substantial difference if I could update it to 4GB?

To no avail, I have done a ton of reading here and there over the last couple of years on how to get TRIM to work for SATA SSDs in a RAID1 configuration.  I believe TRIM would work fine if I switched to RAID0, but that's not what I want to do.

I'm aware of the pros and cons of simply foregoing RAID with SSDs.  I might go that route and I don't need further convincing.  To skip RAID1, I simply need to be convinced that I won't be able to get TRIM working.

I'm also aware that TRIM isn't completely necessary; I just need to expect that the drives won't perform quite as well over time and won't last as long, kind of defeating the purpose of fault tolerance.  Interestingly, the 1TB Samsung 840 EVO drives I'm currently using have been powered on for over 7 years and each have over 53TB of data written to them.  I guess the age of the drives is why I'm getting more anxious to find conclusive answers.

About a year ago, when I decided to be done with Win7, I destroyed the array, erased and TRIMed the drives, re-created the array, and installed Windows 10.  The temporary performance boost after a TRIM was immediately apparent.

I could accept that TRIM with RAID1 is impossible if not for the last statement at the URL below, which practically proves that it can be done with the right motherboard and possibly with the requirement of using a Xeon processor.
