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.

Hi experts.

We're upgrading from Exchange 2010 to 2016 and I already have the design on my head, which will be similar to what we have on 2010, but I'm unsure regarding how many servers will we need to accommodate our mailboxes and run smoothly.

I've tried to use the  Exchange Server Role Requirements Calculator v9.1, but I'm not sure why it keeps giving me so many servers that it can't be right!
The idea is to have enough servers to run smoothly even in the case of 1 of them failing (DAG)
If someone could give me some thoughts on the below, that would be much appreciated.


Resources:
Six databases, with around 200GB each
Total number of users is 1800, around 300 mailboxes per database
Average size of each mailbox is around 400mb (limit is 3GB) (they're small because we have a third-party archiving solution stubbing messages)
Growth: I don't expect us to grow a lot in mailbox numbers, let's say 25% in the next 2 years. In terms of mailbox size, I would say each mailbox could grow up to 50% in the next 2 years, so, each database would go up to 300GB or 350GB.
Outlook - 80% users will work in Online Mode and 20% in Offline Mode.
Daily email flow - Average of 5000 outbound and 12000 inbound emails. In terms of size, they're mostly small emails with a few kb.
Servers will be virtual machines in VMware.
Hosts servers have CPU Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz (logical processors 32) and no RAM restrictions (can go up to 92GB).

Hello,
We have an HP ProLiant ML350 Gen9 E5-2620v3 Server using a Smart Array P440ar controller. Smart storage administrator shows the Logical Drive 1 is queued for rebuilding, this is a RAID 1 array.
We can find no reports of a problem with either of the hard drives, our managements system does not show any evidence of faulty drives.
This is a 2012 R2 server, has anyone seen this? And if so what did you do to correct it?

Thanks All!

As a technician in some cases I need to access a hard drive externally, so I am looking for a USB Hard Drive Docking Station. there is lot of them on the market but looking for one that has the best capabilities of reading (even troubled hard drives to the best possible), also Dual-Bay with Offline Clone [reliable]. and if available (not sure if there is) from a larger size drive to a smaller size [as long the date is less than the target drive].

Any recommendations from experience?

Hi,

I am planning to upgrade to Ryzen and wanted to have a low cost but reliable motherboard brand like ASUS.

My requirement is I need to connect five 3.5 inch desktop SATA hard drives and one Internal SATA Blu Ray Writer.

Does AM4 ASUS PRIME B350-PLUS Motherboard support six 6 gbps/sec SATA devices?

Please reply asap whether I can connect five SATA desktop hard disks and one SATA blu ray DVD writer using the AM4 ASUS PRIME B350-PLUS Motherboard?

Thanks for your support.

Hi,
 
 If you have several USB 3 ports on your Hyper-V server hardware and like to tie some of external USB hard drives to one or more virtual machines to run daily backup from the virtual machine, is that recommended?
 What are the pitfalls?
 I have been running Windows Server Backup from the virtual machine to an external USB 3 hard drive connected to Hyper-V server USB port (so that I can do incremental backup) and I have not had any issues so far.
 But I like to know if there are known issues in this kind of setup.

Thanks.

We have a bunch of old SAS drives from retired servers and they need to be erased or destroyed, so we figured the most cost effective solution would be to get an old desktop, drop an SAS card in it, and use it as a designated drive eraser. We've got no time frame for when this needs to be done so if we can only two a handful each day, it's no big deal.

Has anyone ever used a rig like this before and will it work as intended?

Here's what we were looking at buying - https://www.amazon.com/SAS9211-8I-8PORT-Int-Sata-Pcie/dp/B002RL8I7M

Additionally, I assume we'll need one of those breakout cables so we can connect multiple drives at once.

Will Darik's Boot and Nuke detect the SAS drives and erase like normal, or is there another app I should use?

I have a 128 6g/s ssd c:/ drive. I also have another spare 128 6g/s drive. I know that I can slave them together to make one 256 c:/ drive. The problem I have is I only have one 6d/s motherboard port. What is the best way to slave these drives together?

The motherboard also has a usb3 port. Can I use the spare ssd drive connected to the usb3 pot to slave that drive to the editor c:/ drive?

Also what is the best/cheapest way to slave these drives without erasing the data?

I hope this question is clear enough, if not please let me know.

Thanks
John

Wanting to squeeze a bit more life out of an old home server.

Is it possible to replace the disks in a RAID 1 array with SSDs?

Current raid uses Sata drives on sata 2.

Replace one drive, let it rebuild, then replace the other.

Like the title says I need to upgrade the drive capacity of the SAN. I'll be taking the 8x450GB SAS (currently in RAID6) drives out and replacing them with larger drives. I am unfamiliar with this process (and SANS for the most part) and wondering what all it entails. I know how to physically replace drives I'm just talking about within the configuration of the SAN what I need to do.

The SAN is running the StoreVirtual OS  w/ HP StoreVirtual Centralized Management Console version 11.0. The data is all backed up on the companies BCS appliance so no worries there. I'd just like to know hopefully in a step by step manner what I need to do. Are there services and other things that need to be stopped prior to shutting it down and exchanging the drives etc? When I setup the new volumes how do I configure it so that my production server can see them (again I'm a SAN novice).

Thanks for any help here.

I get the feeling that I don't understand hard drive test results very well.  Or, maybe I do!!
It seems that all of my fellow experts suggest using the manufacturer's own test.  So, OK, I've done that.
I'm using the WD Data LifeGuard Diagnostics here.
The first result says that the WD hard drive gets a "PASS" with a big green checkmark!
Here it is, just to confirm:
SMART Status is PASSThe second result, the Threshold for Raw Read Error Rate is 51 and the Maximum is 200.
That sure sounds like the Threshold has been exceeded.
Also the Warranty flag value is "1" here whereas the others are "0".
The Threshold for Reallocated Sector Count is 140 and the Maximum is 200.
That sure sounds like the Threshold has been exceeded.
Also the Warranty flag value is "1" here whereas the others are "0".
SMART Data
So, is this a problem, as it appears, or not?

We have an new LSI mega raid 9341-8i. This card comes with 2x internal ports. 8643 SAS ports. We need to connect 24 Drives to the card. However we are connecting theses drives through a backplane.

The card says it can connect up to 32 drives in a RAID configuration. How can we connect more than 2 banks of drives using this card. Can we use a SAS Expander and how do we go about doing that?

Thanks,
Robert

Hello!
 Have a client that had 2 drives fail on a HP 212 Smart Array which caused a rebuild.  Upon opening the U1 rack HP server (DL120 G6) I see the raid controlled circuit board looks a little brown, like its beginning to burn up.  The system with the replaced drives is operational and the server reinstall is completed.  For the extra $50 for the controller I don't mind replacing it, however, my concern is will replacing the controller wipe out the array config (3x1tb raid 5).  I don't want to go through the install again. The cables will stay in the same spot, and the array controller only has 1 connection which then branches out to the hard drives.
 Anyone know for certain if replacing the raid controller will be a safe and non-destructive swap?
 Thanks in advance.

The Seagate STDR5000200 external hard drive we have contains every piece of data for our business such as databases and Microsoft office files.

It is locked in a safe for a month at a time.

For a few hours, this Seagate drive would be out of the safe for backing up PC and server data.

The data to backup is on Windows PCs and servers with operating systems such as Windows 10, 7 and XP.

This drive is replaced each month at a time by another drive which contains backup data.

The Seagate backup drive is not connected to a PC or to the cloud.

I believe this drive may not need encryption.

The reason being that if a thief steals it, the fact of them being a hacker is a billion to one.

What is the best password protection for Seagate STDR5000200 external hard drive?

Thanks,
Robbie

Would like to do the above and see two 'banks' of 14 drives, when/if I get that  solved will go to learning how to configure raid arrays in at leaet one to them.
New to all this but the powervaults while old to work in that I can see them in the system, but only one box connected at a time to single port SCSI  card.

Can anyone recommend a company that's proficient in recovering data from failed SSDs? We've tried Ontrack and Secure Data Recovery and they couldn't revive the drive. Does anyone have any insight in regards to what could fail on these drives and how data is recovered from them?  Any SSD recovery experts?
