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.

How delete an app that is locked?

I no longer use CrashPlan, but can not delete it, since it's locked. (Mac)

CrashPlan Locked
I can not log in since the account is gone.

I do seem to be able to access CrashPlan Service Preferences, but doubt they would do anything since there is no connection to the host.

IT Pros Agree: AI and Machine Learning Key

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Hi,

We use Git to manage all of our code for our client’s projects etc.

I’m looking for a solution that will do the following:

01 - backup Git (just in case)

02 - auto backup databases for each client’s project to the same backup service

Thanks in advance for your help.

Cloud Computing: Modern day Architecture of Data Storage
37.jpg
Cloud computing is a general term for the delivery of hosted services over the internet. The availability of high-capacity networks, low-cost computers, storage devices as well as the widespread adoption of hardware virtualization along with service-oriented architecture has led to growth in cloud computing. Cloud computing is the on-demand delivery of computing power, database storage, applications, and other IT resources through a cloud services platform via the internet with “pay-as-you-go pricing”.

The Basics

Running applications that share photos to millions of mobile users or supporting the critical operations of your business, a cloud services platform provides rapid access to flexible and low cost IT resources. With cloud computing, you don’t need to make large upfront investments in hardware and spend a lot of time on the heavy lifting of managing that hardware. Instead, you get the provision of exactly the right type and size of computing resources that you require to operate your IT department’s data storage. Most importantly, you can access as many resources as you need with quick access and only pay for the services that you have utilized.

Cloud computing has three main types that are commonly referred to as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), …

I am betting that an expert here has the answer that Dell cannot solve. It probably will not be easy but I want to see if anyone is up the challenge. I had a Dell 5810 workstation. It failed and Dell could not fix it. They sent me a new 5820 workstation. 32 gigs ram and a one TB ssd. The ssd was supposed to be a class 40 1TB m.2 type drive. They had none in stock so they decided to install a class 20 1TB NOT m.2 type. I refused the lower performance class 20 due to the fact that I paid for a class 40 drive. The class 20 is in an enclosure that slips into a caddy that fits into one of four slot bays in what Dell calls the "Flex System". They decided to send me a 1tb m.2 ssd. I removed the class 20 drive from  the flex bays and installed the 1tb M.2 drive on a daughter board, That seems to work fine EXCEPT that I am getting an error sequence of 4 amber and 6 white flashes on the power led. That indicates a failure having to do with raid. I do not use raid at this time. Dell has no idea  how to fix this error indication.  The computer seems to think it wants to see a raid array. I have no raid. I do not want a raid system. They had me reset the bios to factory. That did nothing. I updated the bios 4 days ago. Yet, there was another bios revision posted today. I loaded that one also with no apparent difference. I feel confident that it is simply a setting that is wrong. When I put the class 20 ssd in and boot from that there is no error light sequence. Dell does not have any more…

Can I use a 172.47.x.x range IP to communicate point to point with an EMC device and a storage server network adapter?

If I add static routes for both they should work right? Despite the 172.47 being a public ip range

Last week we had a issue with our exchange environment where we were unable to send and receive email both internally and externally.

When I ran this command
Get-MailboxDatabase -Status | Select-Object Name,@{N="DatabaseSize GB";E={"$([math]::round($_.DatabaseSize.Tobytes() /1Gb, 2)) GB"}},AvailableNewMailboxSpace | Sort-Object Name | fl

It returned a value that looked like this:
Name                     : Mailbox Database ######
DatabaseSize GB          : 541 GB
AvailableNewMailboxSpace : 84 MB (84000000 bytes)


I checked the drive that exchange resides on and found it to have plenty of free space (365GB).


From all of the research I had found everyone said that exchange will just continue to grow and there is not a (soft limit) in place for Exchange 2013.  I found one anyway and gave it a try
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<Server Name>\Private-<database GUID>
I then added a DWORD key for Database Size Limit in GB setting the value to 700.

After restarting all exchange services I ran the command again and it didn't show anything really different other than the MB remaining continued to dwindle.

So, I figured this must be since the actual "size" didn't change but now it could grow.  Well, when we hit 0MB remaining the DB did grow slightly and the countdown begain again somewhere in the upper double digits.

This continued throughout the day.  I could get mail flowing again with a restart of services or …

I have 5 ESXI hosts. All EXI Hosts can see/have connections to 2 HP fibre Sans and a few ISCSI SANS.
Each ESXI has an add on HP 8GB FC to PCI Express HBA Card.

one of the ESXI host had the system board replaced. When ESXI came back up, it had no problems seeing the ISCSI SANS. But it was unable to see the 2 HP fibre SAN. Looking at the storage adapters, Vsphere client shows "VMHBA1 fibre Channel unknown" while "VMAHBA2 Fibre Channel online"

I have rescan for hardware changes. I see no options to re-attached/mount storage back. How do I get the VMHBA2 to reconnect to the HP SAN? All the other ESXI hosts can see it.

Hey guys,

I’ve two PowerConnect 6224 switches which are linked to a Dell SAN (for redundancy) and one of the switches are then plugged into the local LAN.  I’m changing the local LAN switch but when I connect the Power Connect SAN switch to the new one, it doesn’t work - I can’t access any of the servers on the SAN - it’s a big odd, as there’s no config on the previous LAN Switch- what am I missing?

I have a physical HP DL 380 G7 server 80 GB of memory, 900 GB storage, 1 CPU (Processor cores per socket 4 and total logical processors 8, with hyperthreading enabled).

Every client (5 guest in total) are working via their own terminal server, connected via a remote desktop gateway and asa 5510 firewall on their own vlan. OS is WIN 2008 r2,VMWare version is V6, with latest HP servicepacks on it.

Memory total is 26 GB used

Harddiskspace used is 576 GB

I gave all the guests a total of (vsocket x cores per socket =) 14 VCPU. But as i can see i have only 8 VCPU available, so am I overprovisoning?

My clients are complaining about peformance and freezing of the Remote desktop they run on. I can also see it sometimes. The screen stops, my ping times are rising to 15-25 ms in 2 seconds and than it disappears again and they can work. (i did this from a terminal server from a client and pinged the firewall and the internet).

Is this because of the over-provisioning (14 VCPU in stead of 8 VCPU available ??) does anyone has a solution or has experience with this kind of slowness in VMWare?

Hi. I am attempting to install 16.04 server on a hardware raid 1 array. I created a boot partition (1 mb - I also tried larger, but same error), main disk (3.8 TB) and a swap partition (.2 TB). I am able to install on this configuration, but when the system boots for the first time I receive the error:

"error attempt to read or write outside of disk 'hd0'"

Then, it dumps me to the grub rescue prompt. At this prompt, I have tried setting the root and path to the boot partition, but I am never able to ls see anything in that directory, nor can I get back to the grub menu.

I have read several others with the same problem, but have not been able to recover from this error. Is the main disk too big, possibly? Should I install on a smaller partition? Thanks.

Greetings,

I am running several VMware 5.5 hosts on OEM servers, with each using a MegaRAID LSI 9260-4i SATA RAID controller card with accompanying battery backup unit.   Hosts are managed by a VCenter 5.5  virtual server.  Drive configurations on each host are SATA drives paired in RAID-1 configurations.  I recently got an alarm sounding on one of the servers that 1 of the SATA drives had failed.  I installed the Avago StorCLI utility, and using a  SHOW HEALTH command saw that the state of the virtual drive was degraded, and that the failed drive was on the LSI controller's connector P1.  I shut the system down, pulled out the failed SATA drive, and replaced it with a same-size SATA drive.  On startup the controller card began to beep again, as it was still detecting the degraded virtual drive.  I hit CTRL-H to enter the LSI controller's WEB BIOS and went to add the replacement drive to the degraded virtual drive.  Unfortunately, I could not remove the failed drive from the original RAID-1 Drive Group 0, as it still showed the failed drive in the original mirror setup, as a MISSING PD.  As such I could not add the replacement drive into the original Drive Group 0.  When I tried to add the replacement drive into the Logical Drive setups, the interface created a new Drive Group 1 and wanted to add the new drive to that.  Ultimately I had to declare the new drive as a Global Hot Spare, and I then saw the system start  to rebuild the Drive Group 0 using the new hot spare …

Greetings EE'ers,

I am looking for a good solution for file management and  data storage options for a small Law Office.  There are several "canned" solutions out there that are mostly hosted solutions, which is fine, but they all seem to be pretty expensive.  Does anyone know of any good solutions for this?  Either on prem storage or cloud solution is ok...or even a combination of both, as long as it's compliant for legal documents security requirements.

Thanks!

Thick LUNS and THIN VMDKs

This is how this new environment ive just acquired last month has all their storage setup.

They are using all THICK LUNS at the Array/Block level,  and THIN at the VMware level.

Is this a good idea?  best practices?  

I would like to hear your thoughts

Here is our SAN and VMware environment details:

SAN = all Fibre chanel EMC Unity550F's  All Flash SAS Flash 4

VMware= Vcenter 6.5 10000 Build 6816762
Esxi hosts = 5.0, 5.5, 6.0, and 6.5

The EMC Unity550F's have capability  profiles for VVols but we are not using them.

Last night our SBS 2011 server (with Exchange 2010) had a RAID failure. Would not boot but I could run repair / command prompt and actually copy all of the data to an external drive. RAID drive status is "uninitialized".

 I setup a new SBS server and recreated the 20 or so user mailboxes. The users are back to receiving and sending email on their phones. Outlook clients are the next thing to look at...

I have the entire Mailbox Database folder on an external hard drive. Is there someway that I can dismount the Exchange Store; empty the mailbox Database folder; copy everything from the external drive and mount the Store again?

I also have multiple Server Backups but they are from 11/30 and before.

I'm trying to determine where my bottleneck is as I'm seeing some very poor performance when doing a Storage vMotion migration (migrating VM's to a different host and datastore)

My Vmotion IP subnet is the same as my Management Subnet.( Esxi host management IP subnet on the same subnet as Vmotion)  Is this what is causing the problem?  It is the way this environment was setup before I got here.  Normally I would always separate the Vmotion vlan from the management vlan but that is the way it is here.  

Anyway Is here is my setup

Vcenter 6.5 u1b Build 6816762

Esxi hosts are mixed 5.0, 5.5 and 6.5

Is there a good tool to use to discover the bottleneck?  

I was googling and found iPerf that comes with Esxi 6.5 but ive never used it before.  

Any suggestions?  I really want to improve the storage vmotion performance

thanks

Hi,

I am in the process of cold moving a number of vm's from our old 5.5 platform to our new 6.5. Our storage server comprises of two disks, boot and storage. The storage disk is 2.7tb and is a separate virtual disk on a separate datastore, thin provisioned. When I register the vm on the new 6.5 host the storage disk doesn't get recognised correctly and has an alert icon next to it. The capacity on the disk is listed as zero, and I cannot increase the capacity as the option is greyed out. In the maximum size option it states: N/A Maximum virtual disk size will not be validated if datastore cluster is selected as storage. In the disk name section it identifies the file location in the following format []/vmfs/volume no xxx.vmdk

If I add the disk as an existing disk all seems fine apart from the fact the  maximum disk size is listed as only 67gb (The actual disk size of 2.7tb is picked up) and I cannot change it. The disk file location is listed as expected: datastore name\disk name.vmdk.

Any clues as to why the second disk settings are not picked up correctly? Will the storage disk work/ be safe to use if I dd it as an exisiting disk with the above settings?

Cheers,
Paul

Hi Team !

I just wanted to ask if there is a way to back up SMS ,call logs and contacts from your android smart phone in increments (like dropbox) ?

Is there a way to retrieve SMS , call logs and  contacts if ever you lose the phone  ?

Is there a way to trace the device if it is offline  ? If not what would be the best options as far a tracking the  device and remotely wiping off the data ?

New Samsung phone ,and I don't want to go through it again......

I have a client who set up a Seagate Blackarmor NAS box a number of years back.  It has 4 Seagate 4T SAS drives in a RAID-5 configuration.
I was in their office last week and took a look at the device as it was running very slowly.  I looked at the front panel information (scrolled through the menus) and all four drives were listed as "Good".  The volume was listed as "degraded".

I looked at the web interface and saw that drive 3 was no longer part of the array (not sure if it said offline or bad).  I used the Action button to remove it.

I have since rebooted the box and now the volume is shown (on the front panel) as "Failed".  All four drives show as "good".  On the web interface, all four drives are listed as "good" but there is no volume shown.  I'm hearing no odd noises from any of the drives.

The client's backup is not as recent as he'd like, so he is very interested in trying to get this back up.  I realize that the safest option is to go to a (rather expensive) data recovery service.  He's not likely to want to go that route.

If these were NTFS-formatted drives, I'd have numerous options to analyze and possibly recover the data.  I'm assuming that the box runs Linux and that's not something I deal with except in very rare situations.

One option is to replace the drive that was removed from the array and see if it will recreate the volume.

I'd appreciate any suggestions on how to proceed.

I am having problems moving a virtual drive from one storage location to another on one of my VM Machines but can't understand why. The VM I am trying to move the drive on is our Production SQL server that serves up data for our ERP system. The data and all drives currently sits on a SAN we purchased but the 10K drives cannot handle the requests so I thought I could move that drive that contains the SQL database to a HOST that has a bank of SSD drives. That datastore is 735GB and the drive I want to move is 400GB so it should fit however when I go to Migrate the drive it says that there is not enough room. What am I doing wrong? Can I move a drive off a SAN to a local Datastore on a host? Do I need to move the whole VM drive structure to a new datastore? I was under the impression I could move just one drive which it looks like can be done but I don't completely understand the process.

When I am in the advanced settings of the migration process do I need to tell the application where all the drives need to stay and where to move? I mean In the Advanced window do I need to tell the system to keep all the drives on the current datastore (SAN) and change the one drive to the new location? I was just telling it to move just the drive but each time I would click next it would tell me that there isn't enough space.

Hi
I talked with a Fujitsu storage representative and he quoted out a Fujitsu Eternus DX100.
Afterwards i have spoken with a Dell rep and he quoted out a Dell EMC ME4024.
Now I would like to know why the Dell storage so much cheaper is then the Fujitsu Eternus DX100 with the same config? Are the specs from Dell just advertisement? Does Dell tiering mean the same as Fujitsu tiering?
Does anyone here used this products or is familiar with it?
