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 have a hp z800 and want to setup esxi 5.5 on it as a home lab but i am not sure what kind of disks to purchase and how to configure the built in intel raid (is this considered as software raid? If so i dont think ESXI supports software raid and I may need to purchase a physical LSI - pcie raid hardware card)  so that vmware will be able to see my hard drives as a datastore. I will also be running esxi off of a usb thumb drive.

I also believe 2TB drive is the largest siz drives i would get (i know some of it gets lost but how many 2 TB drives would i be able to use and what would be the expected available size after setting them up in raid and what it the best raid configuration to put it into Raid 5, 10?

Thank You in advance for your time!

Prepare for the PMI Agile Certified Practitioner (PMI-ACP)® exam, which formally recognizes your knowledge of agile principles and your skill with agile techniques.

Server 2008 Standard -- SQL 2014 -- Need to recover two folders from RAID 5 (4 disks).    System failed to boot and rather than spend incredible amounts of time (beyond attempting to boot to 'last known' or attempt 'safe mode'), just popped in four new drives and reinstalled operating system and SQL2014.

However, I need a couple of folders off the broken array.   Any suggestions on how to get these rather than send the drives out?   It sure would be nice to get the server back online so staff can come back to work.  (sigh).

We currently have Dell PowerVault MD3220i in our office. It's setup with two Dell PowerEdge R620 servers in a fail-over cluster configuration.
We purchased the PowerVault with only half of the disk slots occupied. I recently purchased 12 more drives in order to expand the volume capacity.
I've been told that this is a seamless process which should not incur any downtime. I have looked at the owner's manual but don't find the instructions to be clear.

Does anyone have a set of clear step-by-step instructions on how to add additional hard drives and expand the volume on the PowerVault MD3220i using the Dell Management software without any downtime?

Great appreciated!!

I had this question after viewing So many files still in DfsrPrivate\Staging folder.

Server A and Server B have a large difference in space used on the hard drive. Server A is primary and replicates to Server B. I have determined the difference is 100% due to Server B D:\System Volume Information\DFSR\Private location. I am afraid to just delete those files and I am unsure how to check "ConflictAndDeleted". How do I clean this up and why did it happen in the first place?

I am building a mini media player for a friend in a very rural area without internet. It is progressing well. I got a 32” monitor and use it’s usb to power a raspberry pi 3 B+ running raspbian stretch with the hdmi connected to the monitor for video and audio. This all works. I added Kodi and using wondershare video converter I’ve been capturing my dvd’s And converting to MP4. This also works fine. My friend had an old dead Mac with mp3 music so I’ve been scraping the hard drive to recover songs and plug those into Kodi music and this works.
What I can’t get to work is Bluetooth audio from Kodi to a Bluetooth anything. I can get pairing and connect at the raspian level but Kodi ignores it.
Help?

I need the .inf file for a WD hard drive WD5000LPLX in order to run Acronis Universal Restore.   I have looked on the WD website and also in Device Manager under drivers, but I cannot find the .inf file.   Acronis needs this in order to restore to different hardware.

Hi

I am about to do a server refresh.

thoughts on a HP Server running PureStorge and underpinned with DATTO Siris all flash backup device.

OR..

DELL EMC running DELL EMC SAN (all flash) and DELL DataDomain to store the Veem backups.


Any thoughts....

Hello all,

My office is having a planned power outage and will need to shut down our 8 year old Dell EqualLogic PS6110 and start up after outage.
The SAN is connected to 3 ESXI hosts with total of 44 VMs.

I am wondering if anyone has a SOP on SAN shutdown and start-up process.
From what I know, the sequence goes like all VMs > ESXI hosts > SAN array > power off SAN.

Does this sound right? Am I missing any steps?

I am also curious about the start up process for the SAN array. Do I just power on SAN then use DB9 console to connect to array and start it?

Thanks!

We have HP HPE P4300 G2 Storage Systems, i have made 2 arrays, in first array i have put operating system (Win 2012), second array it has 13TB.
I am trying to add this new SAN server in HPE StoreVirtual Centralized Management Console, but its not picking it up, i have attached screenshot.
Do i have to add Initiator Node Name? i tried to look through i didn't find that information.
How can add the new SAN Storage to HPE StoreVirtual CMC?

Thanks.

I have DELL SAN Equallogic 6100 and showing amber light on the front panel. In the console, there are two members and when I click on controller1 has got control slot 0 on fw version 9.1.2(secondary) and control slot 1(active) on fw version 8.1.1. Controller2 has only one slot 0(active) with fw version 8.1.1

warning shows "control module cache syncing. do not turn off power to this member during this operation" How to fix this amber light/warning?

Copying contents from one hard drive to another with this command

xcopy j:\ d:\ /h/i/c/k/e/r/y

How can i verify that everything copied and if not identify the files that did not copy

In MS environments we manage, we often use virtual drives for storing WSUS updates, system backup dump files, security video and so forth.  I create a folder on the storage device, build a virtual drive in that folder, initialize and mount the drive; all is well.  The problem is that the drives will not stay mounted.  I haven't been able to focus in on what causes them to disconnect, but it seems like something as mundane as a reboot will cause the drive to disconnect and it will not connect again unless it is reconnected manually.  Meanwhile, WSUS, backups, and cameras have issues due to storage problems.

I've tried to have scheduled tasks periodically dismount and remount the drive, but that has not proven to be reliable, either.

Therefore, I am open for suggestions.

The below is a result of running Gparted on an external hard drive. I wonder what the best course is to repair it?
fwiw there's an ntfs partition on the disk too which i can read fine.

Hello Team.

Does anyone has NetApp OnCommand Unified Manager custom reports you're using in your environment?

What I'm trying to achieve is :

1) Total Storage Raw Vs Allocation vs consumption for each data centre (with 12 months trend).
2) Allocation vs consumption for each aggregate per DC (with 12 months trend).

Also, monitoring AltaVault is a challenge. It does not provide detailed scheduled reports on all Storage stats; just Total vs Consumed. Anyone has any success with that?

Hello!
I have a user who uses a Macbook Air that is on MacOS Mojave 10.14.3. He has an issue where he connects to the network drives on our file server and after some time encounters this exact issue:

http://www.thursby.com/why-does-it-say-connection-failed-when-i-click-server-sidebar

I wanted to ask if anyone has any new information on it since his OS version is definitely a few steps up from what are described as the problematic versions? Or if anyone has found a cause for it that can be mitigated? The only third party softwares he has are Office 2016 for Mac, Webex client with Outlook add-in, and SEP 14. Anyone have any ideas? Thanks!

Hi I have a RAID 6 Adaptec 7805 Controller

https://storage.microsemi.com/en-us/support/raid/sas_raid/sas-7805/

I have 4 SATA drives in a RAID-6 configuration running on Windows 10 Pro for Workstations - under NTFS.

I realize that if a drive fails then the other one takes over.

So here is a few questions

1. How does the RAID controller will help me protect me? (I am assuming it does).
2. Would a bad sector only be detected when it is accessed?
3. If a bad sector is detected - can I assume it is reconstructed from the other good sectors on the other disks?
4. I was considering moving the file system to ReFS with integrity streams on - would this give me any extra benefit?

So what I am looking for is a more detailed explination on how this works. Plus any other info that would be usefull.

Thanks,

Ward.

Hi Everyone,

Last ditch effort here, I think I tried everything but I want to be sure I don't miss any ideas.

I was given a USB external hard drive that isn't detecting. When you hook up the power I think I can feel the drive spin up but after that, nothing. No USB device is detected in Windows 10. So I took the case apart and removed the HD. It's a 1TB Western Digital Black, manufacture date August 2010. I connected it to power and a SATA cable. Drive spins up then down, and seems to do that ad-infenitum.

I think he's dead, Jim. Unless there are other ideas? I already know there is no interest it taking it for professional recovery or trying to get the platters into another shell. I didn't try any sort of drive recovery tools so far, but given the fact that it isn't detecting in Windows at all (nothing new in device manager) is there any chance those will work?

Searching for publisher files using *.pub from the root of about 10 google drive folders on my hard drive does not appear to be working.

Do I need to change the default indexing settings somewhere or do something special since they are google drive folders?

I am on a Windows 10 Microsoft Surface 4 Pro.

Thank you for any assistance that you can provide on this.

My organization currently has a physical server with 256gb RAM and 2 x 4tb internal Intel P4500 SSD cards. It's a Hyper-V host and all of the VMs live on the internal SSD cards. Performance is great but I'm exploring options for expanding our storage.

Rather than having all of the storage within the server box, one obvious alternative is a SAN. But the SAN configurations I'm looking at are over $30,000. Boooo.

It seems like NAS devices are getting a lot more powerful, robust and (with Flash drives) faster.

So my question: Is it feasible to load up a Synology with Solid State drives (or a hybrid combination), connect it directly to the server and then run all of the VMs off of there? And would it be best to connect using dual 10GbE direct Ethernet connections and iSCSI?

I fully understand a NAS is not a SAN. I am trying to consider in-between solutions. I know how my VMs run with internal storage. I know how my VMs will run on a SAN. But what if I ran all of my VMs on a NAS? (the SAN solution I am looking at blows away my current solution as far as IOPS so I might even say a SAN is overkill. With my current solution we are not experiencing any latency or speed issues)

Another question - if this is feasible, then would I be able to connect TWO or THREE servers to the NAS and have them all share the same NAS volume?

White papers or actual real-world examples would be great.

following is my Hyper-v Host configuration.

Hyper-V host running on SSD M.2 and all my VM  VHDX files sitting on local drives (4 x 600 GB Hard Drive - SAS 15K - 3.5" Drives in Riad 5).
I have Two Guest VM's (DC & file server).
I have configured a separate hard disk VHDX (1TB DYnamic) for DATA and attached to my file server.
Then I started transferring my old file server files to new File server DATA Disk.
While transferring data I couldn't access the new file server. The server was in the hung state. But i cold access my other VM which is DC without any issue.

Did the following tuning on Hyper-v setting

Disable VMQ/Enable Jumbo Frame/Disable IPV6
Separate NIC for Management OS and Team NIC for VM's

I am using a Promox VE on my local ML110 xeon 28GB 480GB SSD server. and wish to backup on my Qnap TS-253A 8GB ram nas server.

Normally I log into the local server with: https://snag.gy/RYE3Sm.jpg URL: https://192.168.1.20:8006/#v1:0:18:4:::::: user id: root and then the password. but when I try to log in, it's not working: https://snag.gy/D9zsEx.jpg 

I downloaded nakivo for the backup.
