New enterprise 14 TB HDD options cater to cloud-scale users

The latest wave of helium-based 14 TB hard disk drives shows there’s still innovative life in the storage media, mainly for cloud-scale users in need of economical, high-density drives.

Seagate Technology this week launched its new 14 TB helium hard drive portfolio. It includes the 12 Gbps SAS- and 6 Gbps SATA-based Exos X14 designed for hyperscale data centers and SATA-based IronWolf for NAS, SkyHawk for surveillance systems and BarraCuda Pro for desktop workstations and DAS.

Toshiba recently disclosed that it’s sampling 14 TB and 12 TB helium-sealed 7,200 rpm SAS HDDs with 12 Gbps data transfer rates. They join Toshiba’s previous helium-based 14 TB HDD that uses the 6 Gbps SATA interface.

Earlier this year, Western Digital began shipping helium-based 12 Gbps SAS- and 6 Gbps SATA-based 14 TB HDD models to select hyperscale cloud customers. China-based internet service provider Tencent, a customer of Western Digital’s 12 TB HelioSeal HDDs, confirmed it was qualifying the latest 14 TB Ultrastar DC HC530 drives. The 14 TB HDD models use helium instead of air to reduce aerodynamic drag and turbulence inside the drives. Helium-based HDDs require less power and enable manufacturers to use thinner disks and squeeze in more tracks to store more data per HDD.

Shingled magnetic recording

In June, Western Digital disclosed Dropbox as a customer for its 3.5-inch helium-based 14 TB Ultrastar DC HC620 HDD. The drive — formerly called the Ultrastar Hs14 — uses host-managed shingled magnetic recording (SMR) technology, in contrast to the two-dimensional magnetic recording the Ultrastar DC HC530 uses.

Dropbox qualified and deployed Western Digital’s SMR-based HC620 HDD for its custom-built Magic Pocket storage infrastructure. A Dropbox blog noted the SMR HDDs offer higher bit density and lower cost per GB than HDDs that use conventional perpendicular magnetic recording technology, which aligns bits vertically rather than horizontally.

Conventional magnetic recording enables random data writes across the entire disk, whereas SMR is best suited to writing data in sequential mode. Dropbox chose the host-managed SMR HDDs for the Magic Pocket workload because its storage architecture is geared for sequential writes.

But the Dropbox scenario is not the norm at this point. John Rydning, an IDC analyst who focuses on HDDs, said demand is low for SMR technology because customers would need to tweak their systems in order to use drives designed for sequential rather than random writes.

“With SMR, tracks on the disk are partially overwritten intentionally — like shingles on a roof — to increase the number of tracks on the disk and increase the storage capacity per disk,” Rydning wrote in an email. “Yet, it’s difficult to change or modify data once it’s written to the disk.

Seagate 14 TB HDD
Seagate’s IronWolf 14 TB HDD is designed for network-attached storage.

“Think of what it’s like to change a shingle in the middle of a roof. You have to peel off a few rows to change one shingle. Similar for SMR HDDs. To change data already written to the disk, you have to read several tracks to cache, modify the data in cache, then rewrite to the disk.”

Rydning said the competition for 14 TB HDD market share in the near term will center on drives that use conventional magnetic recording rather than SMR technology.

Additional high-density HDD technologies in the works include heat-assisted magnetic recording and microwave-assisted magnetic recording (MAMR), but those options have yet to emerge in commercially shipping products. Western Digital said last year that it expects to begin shipping ultra-high capacity MAMR HDDs in 2019 and claimed that MAMR has the potential to enable HDDs of 40 TB and beyond by 2025.

Toshiba’s nine-platter 14 TB HDD

In the conventional magnetic recording space, Toshiba’s new MG07SCA 14 TB HDD uses a nine-platter helium-sealed mechanical design unlike the eight-disk 14 TB options from rivals Seagate and Western Digital. Toshiba uses eight platters with its helium-based 12 TB MG07 model, after using seven platters with its traditional air-based MG06 10 TB generation, said Scott Wright, the company’s director of HDD marketing.

Toshiba lagged competitors on previous product generations with 8 TB, 10 TB and 12 TB HDDs, IDC’s Rydning said. The company is now time-to-market competitive with Western Digital and Seagate with 14 TB HDDs for cloud-scale customers and positions itself well for higher capacities in the future, he said.

But Toshiba’s nine-platter 14 TB HDDs carry a higher manufacturing cost per drive for the extra disk and two heads than the eight-platter 14 TB HDDs from Western Digital and Seagate, Rydning said. “On the other hand, given that Western Digital and Seagate are using the higher areal density heads and disk, they may encounter production yield challenges in the first one or two quarters of production,” he said.

Toshiba didn’t disclose retail pricing for the MG07SCA 14 TB HDDs.

Enterprise HDD market leaders

Seagate and Western Digital lead the market in nearline enterprise-class 7,200 rpm SAS and SATA HDDs, according to Trendfocus vice president John Chen. Seagate has the edge in units shipped, and Western Digital leads in exabytes shipped, Chen said. SATA is the dominant interface for nearline HDDs, with SAS at only about 20% unit share, he said.

SATA HDDs are single ported, but Toshiba’s Wright said there’s still demand for dual-ported SAS HDDs among users who want to map redundant paths to each storage device for high availability. He said some customers want to be able to support SSDs and HDDs in a common architecture, with the same 12 GBs data transfer rate.

Wright doesn’t expect the new wave of upcoming 3D NAND flash-based SSDs that store four bits of data per cell — known as quadruple-level cell (QLC) — to eat into the nearline enterprise HDD market that is “all about cost of capacity.”

“Where we see solid state challenging HDD is in very low capacities, at the lower end of the notebook PC market, and then also, of course, on performance at the high end of the enterprise market where some SSDs are being used in place of the traditional 15,000 rpm types of high-performance [hard disk] drives,” Wright said.

PowerShell commands to copy files: Basic to advanced methods

Copying files between folders, drives and machines is a common administrative task that PowerShell can simplify. Administrators who understand the parameters associated with the Copy-Item commands and how they work together will get the most from the PowerShell commands to copy files.

PowerShell has providers — .NET programs that expose the data in a data store for viewing and manipulation — and a set of common cmdlets that work across providers. These include the *-Item, *-ItemProperty, *-Content, *-Path and *-Location cmdlets. Therefore, you can use the Copy-Item cmdlet to copy files, Registry keys and variables.

The example in the following command uses variable $a:

Copy-Item -Path variable:a -Destination variable:aa

When working with databases, administrators commonly use transactions — one or more commands treated as a unit — so the commands either all work or they all roll back. PowerShell transactions are only supported by the Registry provider, so the UseTransaction parameter on Copy-Item doesn’t do anything. The UseTransaction parameter is part of Windows PowerShell v2 through v5.1, but not in the open source PowerShell Core.

When working with databases, administrators commonly use transactions — one or more commands treated as a unit — so the commands either all work or they all roll back.

PowerShell has a number of aliases for its major cmdlets. Copy-Item uses three aliases.

Get-Alias -Definition copy-item

CommandType     Name           Version    Source

———–     —-            ——-    ——

Alias           copy -> Copy-Item

Alias           cp -> Copy-Item

Alias           cpi -> Copy-Item

These aliases only exist on Windows PowerShell to prevent a conflict with native Linux commands for PowerShell Core users.

Ways to use PowerShell commands to copy files

To show how the various Copy-Item parameters work, create a test file with the following command:

Get-Process | Out-File -FilePath c:testp1.txt

Use this command to copy a file:

Copy-Item -Path C:testp1.txt -Destination C:test2

The issue with this command is there is no indication if the operation succeeds or fails.

When working interactively, you can use the alias and positional parameters to reduce typing.

Copy C:testp1.txt C:test2

While this works in scripts, it makes the code harder to understand and maintain.

To get feedback on the copy, we use the PassThru parameter:

Copy-Item -Path C:testp1.txt -Destination C:test2 -PassThru

    Directory: C:test2

Mode          LastWriteTime    Length Name

—-          ————-     —— —-

-a—-       13/08/2018  11:01    40670 p1.txt

Or we can use the Verbose parameter:

The Verbose parameter
Administrators can use the Verbose parameter to see detailed output when running PowerShell commands.

The Verbose parameter gives you information as the command executes, while PassThru shows you the result.

By default, PowerShell overwrites the file if a file with the same name exists in the target folder. If the file in the target directory is set to read-only, you’ll get an error.

Copy-Item -Path C:testp1.txt -Destination C:test2

Copy-Item : Access to the path ‘C:test2p1.txt’ is denied.

At line:1 char:1

+ Copy-Item -Path C:testp1.txt -Destination C:test2

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+ CategoryInfo          : PermissionDenied: (C:testp1.txt:FileInfo) [Copy-Item], UnauthorizedAccessException

+ FullyQualifiedErrorId : CopyFileInfoItemUnauthorizedAccessError,

Microsoft.PowerShell.Commands.CopyItemCommand

You need to be a PowerShell Jedi to overcome this. Use the Force parameter:

Copy-Item -Path C:testp1.txt -Destination C:test2 -Force

As part of the copy process, you can rename the file. You must include the new file name as part of the destination. For example, this code creates nine copies of the p1.txt file called p2.txt through p10.txt.

2..10 | foreach {

 $newname = “p$_.txt”

 Copy-Item -Path C:testp1.txt -Destination C:test$newname

}

PowerShell commands to copy multiple files

There are a few techniques to copy multiple files when using PowerShell.

Copy-Item -Path C:test*.txt -Destination C:test2

Copy-Item -Path C:test*  -Filter *.txt -Destination C:test2

Copy-Item -Path C:test* -Include *.txt -Destination C:test2

These commands copy all the .txt files from the test folder to the test2 folder, but you can also be more selective and only copy files with, for instance, a 6 in the name.

Copy-Item -Path C:test* -Include *6*.txt -Destination C:test2 -PassThru

    Directory: C:test2

Mode        LastWriteTime       Length Name

—-         ————-      —— —-

-a—-       13/08/2018 11:01    40670 p6.txt

-a—-       13/08/2018 11:01    40670 x6.txt

You can also exclude certain files from the copy operation. This command copies all the text files that start with the letter p unless there is a 7 in the name:

Copy-Item -Path C:test*  -Filter p*.txt  -Exclude *7*.txt -Destination C:test2

PowerShell copying
Administrators can fine-tune the PowerShell commands to copy certain files from a folder and exclude others.

You can combine the Path, Filter, Include or Exclude parameters to define exactly what to copy. If you use Include and Exclude in the same call, PowerShell ignores Exclude. You can also supply an array of file names. The path is simplified if your working folder is the source folder for the copy.

Copy-Item -Path p1.txt,p3.txt,x5.txt -Destination C:test2

The Path parameter accepts pipeline input.

Get-ChildItem -Path C:testp*.txt |

where {(($_.BaseName).Substring(1,1) % 2 ) -eq 0} |

Copy-Item -Destination C:test2

PowerShell checks the p*.txt files in the c:test folder to see if the second character is divisible by 2. If so, PowerShell copies the file to the C:test2 folder.

How to use PowerShell cmdlets to copy, move
and delete files

If you end up with a folder or file name that contains wild-card characters, use the LiteralPath parameter instead of the Path parameter. LiteralPath treats all the characters as literals and ignores any possible wild-card implications.

To copy a folder and all its contents, use the Recurse parameter.

Copy-Item -Path c:test -Destination c:test2 -Recurse

The recursive copy will work its way through all the subfolders below the c:test folder. PowerShell will then create a folder named test in the destination folder and copy the contents of c:test into it.

When copying between machines, you can use UNC paths to bypass the local machine.

Copy-Item -Path \server1fs1testp1.txt -Destination \server2arctest

Another option is to use PowerShell commands to copy files over a remoting session.

$cred = Get-Credential -Credential W16ND01Administrator

$s = New-PSSession -VMName W16ND01 -Credential $cred

In this case, we use PowerShell Direct to connect to the remote machine. You’ll need the Hyper-V module loaded to create the remoting session over the VMBus. Next, use PowerShell commands to copy files to the remote machine.

Copy-Item -Path c:test -Destination c: -Recurse -ToSession $s

You can also copy from the remote machine.

Copy-Item -Path c:testp*.txt -Destination c:test3 -FromSession $s

The ToSession and FromSession parameters control the direction of the copy and whether the source and destination are on the local machine or a remote one. You can’t use ToSession and FromSession in the same command.

Copy-Item doesn’t have any error checking or restart capabilities. For those features, you’ll need to write the code. Here is a starting point:

function Copy-FileSafer {

 [CmdletBinding()]

 param (

   [string]$path,

   [string]$destinationfolder

 )

 if (-not (Test-Path -Path $path)) {

   throw “File not found: $path”

 }

 $sourcefile = Split-Path -Path $path -Leaf

 $destinationfile = Join-Path -Path $destinationfolder -ChildPath $sourcefile

 $b4hash = Get-FileHash -Path $path

 try {

    Copy-Item -Path $path -Destination $destinationfolder -ErrorAction Stop

 }

 catch {

   throw “File copy failed”

 }

 finally {

   $afhash = Get-FileHash -Path $destinationfile

   if ($afhash.Hash -ne $b4hash.Hash) {

      throw “File corrupted during copy”

   }

   else {

     Write-Information -MessageData “File copied successfully” -InformationAction Continue

   }

 }

}

In this script, the file path for the source is tested and a hash of the file is calculated. The file copy occurs within a try-catch block to catch and report errors.

With additional coding, the script can recursively retry a certain number of times. After each copy attempt, the script can calculate the hash of the file and compare it to the original. If they match, all is well. If not, an error is reported.
