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.

What's my consideration between the implementation of SAN and vSAN ?  Will there be any performance difference between them ?

Thx

I made a backup copy of a 1TB hard drive on a new, clean 1TB hard drive (let's call it Drive B) a few days ago. No hassles, no problems.

Today, 5/17/2018, I went to move some files from Drive B into my laptop to do a little work on them. These files were in a folder on the first drive:

Past Years/2016/Previous Months/08/27/shows

After I made the corrections I saved the files back to the SAME folder. Later, I went back in to check them and saw that the dates of ALL the files in that folder--including the ones I never touched when I worked on the few that I did--showed the date information as: Date Created 5/17/18.

What the heck is going on here?

How does the date get changed on files like this? This makes replacing some files with the same name a really confuding task!!!

the user and groups are existing and correct but still showing error. I think it is not able to extract user or group information from domain controller.

I recently rebuilt a computer with the following specs:

- Windows 10 Pro
- Asus TUF Z270 Motherboard (UEFI BIOS)
- Samsung SSD 840 Pro 512GB Hard Drive (C:)
- 2 x Seagate SkyHawk 4TB SATA Hard Drive (Storage)

Two weeks ago, the computer suddenly restarted without warning while I was using it and it couldn't boot. Went into BIOS and found out that C: and one of the SkyHawks weren't being detected. So I unplugged the two SkyHawks and rebooted. The OS ran an automatic disk check on C: and I was able to boot in afterwards. So then I decided to try to reconnect one of the SkyHawks (A). No problem there, so I plugged in the other SkyHawk (B). After testing with a series of configurations, I found out that having B plugged in was causing the issue so I left it unplugged.

Two days ago, the computer started doing the same thing again although I still had B unplugged. I went into the BIOS and C: wasn't being detected again. After leaving it turned off for a while, I was able to boot to the OS today. I went and downloaded the Samsung Magician software to find out the status of the SSD and it scanned ok. I restarted again to test it and now it's back to not detecting C:.

Could it be a setting in BIOS? A bad SSD? If it's a bad SSD, is there another brand-specific tool aside from Samsung Magician that I can use to test it? Or is there a dependable third-party software out there for testing SSDs?

By the way, I also replaced the SATA cables but same deal.

I would like to check if data at rest encryption is turned on in my Isilon cluster.

From what I have read Isilon does it automatically with the use of SED (Self encrypting drives).

Is my understanding correct?

And how can I check if the drives on my system are self encrytping?

 

Also if we setup cloudpools then how can we make sure that data will be encrypted on the cloudpool side as well?

We are thinking of using cloudpools to archive data to a third party provided storage service.

The third uses Isilon cluster on their side as well to provide storage for use with cloudpool.

I have read that if cloudpool is being used with another Isilon as the archive location then no cloudpool license is required. Following article says "The CloudPools license for using either another Isilon cluster or EMC ECS will be free to customers." :-

What’s New in Isilon OneFS 8.0 | GeekFluent

Also, one of the EMC documentation mentions the same thing.

 

But the third party vendor is saying we need the license and the config options for cloudpool are greyed out in our system.

Please advise if this is possible without the license requirement?

I want to build a USB drive that boots to a (Grub) bootloader that has a multitude of tools that I have.

1 of the tools would be Windows installation images (10, 7, 8, Server 2016, etc)
Another will be a Windows PE-Based, disk destroyer that wipes hard drives, and Acronis.


I am getting tired of losing drives with 1 tool on it that I need, as well as having multiple 32gb drives that are only using a couple megs to a few gigs.

I have used xboot, WinsetupfromUSB, Yumi, none of these work. None of them write multiple Windows ISOs to 1 USB drive.

Any ideas?

Please help! I have 3 WD 1TB external harddrives, all formatted to Exfat. My mac ios 'saw' all three until recently, when it decided to not mount one of them - it doesn't show up in utilities either. I have done a search, but cannot format the drive as I need to back it up, and can only do this on my mac. I use the drive between windows and mac, but my laptop doesn't have enough memory to back up. So I need to back up via the mac that won't see my drive :(

One of my colleagues moved a Brocade 200E Switch(Switch3) from Fabric2 to newly created Fabric3 in Brocade Network advisor.

As soon as that was done the log in Network advisor says the ISL between switch2 & switch3 was broken.

Switch3 was the master in Fabric2.

Topology of Fabric2 was :

Switch 1 ---> Switch2 ----> Switch3


Also, if I run the "switchshow" command on the Switch2 then all ports show as disabled.


This would explain why ISL is broken but I am not sure why all ports got disabled on switch2?


Has creating Fabric3 in Network Advisor introduced a third fabric with a different Fabric ID?


Is it safe to enable the ports on Switch2(especially ISL port)?


And can we safely remove switch3 from Fabric3 and discover it back in Fabric2?

Would it retain its config if we do that?

Would this cause any other problems?

UPDATE: While some of these solutions looked promising, none resolved the issue. I had to send the drive back to Samsung who cleared it. I only  hope my experience helps someone else.

Hard drive locked after moving HD to another computer.

I know the story I'm about to relay is going to be challenged as impossible, so if that is your response, please just save it for someone else. What I'm about to tell you is exactly what happened.

I have an HP EliteDesk with Win 10. When I got it first thing I did was clone the slow HD to an SSD drive. That want flawless. About a year later I got an M.2 drive for another computer but that computer would not work with the M.2 drive so I tried it out in the HP and it worked great with an adapter card ($20 on Amazon). The SSD M.2 benches at a full 3.3G/s using Crystal Mark.

So now I had the 2nd drive (the first SSD SATA3) extra. I kept it for a few months just in case and as a backup.

I was working on a new build. I was having problems with HDD activity. It was another Samsung SSD drive. I thought maybe it's the drive. So I pulled out the spare SSD with Windows 10 and attached it and booted. I did not expect much, I figured Windows would come up in safe mode or ask me to authentic, etc. But instead nothing happened. Zero boot. I unhooked it, put the original drive in and it booted fine.

So I thought  "wow, that's weird, I guess I didn't really have a good backup or something went wrong with the drive... " So I took it back …

I have an old Dell PowerEdge 2800 domain controller sitting in my office that is collecting dust.  I was thinking about converting it into a server that we can use to backup the hard drives of the individual workstations in my office.  It has a boatload of hard drive space in a hardware RAID array, which I believe is large enough to hold the workstations.  There are 9 workstations that would need to attach to the server.  Right now, it has MS Server 2003 installed on it, but not much else.   Our workstations are a mix of Windows 7, Windows 10, and I think we have one Windows 8 laptop.  On a suggestion from a guy who does some IT for us now and then, I was thinking about reformatting the server with Linux to do this job, but I don't know if that is the best way to go about it because I haven't used Linux since college.  

My question is this:  Is there a software solution available that will allow us to automatically backup our workstations to an old server that is relatively simple to install and maintain?  We have a small business and don't have dedicated IT staff, so I will probably have to do this myself and I don't want to have to learn something really complicated.
 
 We don't need the domain server anymore and I am willing to install a different operating system if necessary.  Thanks for any suggestions.  If the suggestion is to go with another operating system, please let me know the build or the version.  Thanks.

Hi,

 I like to know if there is a software tool that shows how many hours a hard disk has been used. The reason is that I need to get some Seagate 15K 600GB SAS hard drives and Seagate does not make them anymore. I can buy "NEW" Seagate 15K 600GB SAS hard drives from Ebay or AMAZON, but I like to be able to check whether these hard drives are really new or have some hours on them.

Thanks.

I have a Sarbent Hard Drive Docking Station (DS-UBLK) and it was working perfectly fine. A few days after I updated OSX (10.13.3), I no longer see the icon. I can't find it anywhere.

I talked to the support at Sarbent and they just sent me another docking station which doesn't work either.
They have a driver for windows, nothing for mac.

I borrowed another docking station (Thermaltake BlacX): nothing.

Could there be a problem with the new OSX update? Or maybe that's not the problem at all. Could my harddrive just be dead?

I found a similar question here: https://www.experts-exchange.com/questions/26572667/Why-doesn't-my-laptop-recognize-the-Thermaltake-Blacx-hard-drive-docking-station.html

But I'm not computer literate enough to know if I have the same problem.

Also, I tried to downgrade the OS to before the update. And you need Time Machine for that.
The problem is that the hard drive I use for my docking station IS the Time Machine.

Thank you.

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

Robert

Hello all,

We are planning to upgrade our ESXi infrastructure, with new hosts, a new vCenter server and a new SAN.

Our current setup is: Running VMware Essentials with 3 hosts connected in a cluster with a SAN. We are planning to have the same setup as the old one but with newer hardware. What would be the best approach to migrate the virtual machines from one environment to another? Would it make sense to purchase another VMware essentials license and stage new infrastructure along the old, and migrate between the two? What would be the best approach in this situation?

Old SAN is a Dell MD3600i and the new SAN will be a NetApp FAS2620. Old servers are Dell R710s and the new will be Cisco UCS C200 M5's.

Thanks in advance!
