Vol. 17, #41 - October 8, 2012 - Issue #900
This week's issue of WServerNews is all about hybrid drives, which Wikipedia defines as "different from standard hard drives in that it integrates a cache using non-volatile memory or even a small solid-state drive." Yes I just quoted something from Wikipedia--you can now see the depths to which this newsletter has plunged.
But hybrids are really nothing new. Consider the Terminator for example, who as a cyborg might best be described as a hybrid of Arnold and a Meccano set. Terminators are commonly considered destructive, but did you know they can also be MOTIVATED BY LOVE?

Before we get to this issue's main topic, let's briefly dig into our Mailbag:
An anonymous reader has added to our growing list of deprecated and removed features in Windows Server 2012 with the information that the following command-line tools have now been marked by Microsoft as deprecated:

You missed the best company of them all Aruba Networks. I know they make wireless gear, but the VIA client and the Remote Access Point (RAPs) are excellent. I love having all my work SSIDs broadcast for me to use if I need to connect.

Todd, an IT manager with many years of experience, voiced his response to the term "cloud" as follows:
When management hears all the annoying "Cloud" hype, they get all glassy eyed with big smiles, thinking that some IT miracle has landed. The term "Cloud" has clouded many senses of reality into thinking this is some new invention. Of little importance is the origin of the term: a cloud was an icon we placed on network diagrams indicating that there was a connection to the Internet. Now suddenly any online service, (email, data backup and storage, document management, etc.) to which you are willing to relinquish control, security, and reliability becomes a "Cloud" service.
So, other than the catchy new "Cloud" name, what has really changed? Did I fall asleep and miss out when we suddenly built an entirely new Internet infrastructure? Seems this is more of an ingenious marketing ploy to convince the unknowing that they absolutely must move their company's IT needs to the "Cloud" or they will be in the stone-age.
I am already hearing the grumblings of those who didn't fully realize that productivity now depends on the reliability of their ISP and those "me-too" service providers.
Thanks for listening to my grumblings and chuckles. As you can probably tell, I have been in IT for over 32 years :)
I definitely agree that from a marketing standpoint "cloud computing" has been overhyped to the point that almost any Internet service now constitutes a "cloud service" from the typical provider's perspective. But my point in the last issue was that NIST has come up with a clear definition of what "cloud computing" should look like from an enterprise perspective, and the more serious vendors basically agree with this definition. I suggest that it's useful to have the NIST definition at your fingertips so when a vendor comes to you and starts babbling cloud this, cloud that, you can hold your fingers up and start counting them off with questions like these:
But I'm sure all you 30-year-plus MIS types already know what the right questions are to ask of vendors ;-)
Hybrid drives have been around for a few years now, and enterprises have started using them for both clients and servers. Why? What's so special about the hybrid drive?
Understanding the need
A traditional hard disk drive (HDD) can consume about 15% of the power for a laptop. HDDs are also shock prone, slow to spin up, and create a performance bottleneck because of their seek time and rotational latency. HDDs are basically the most common point of failure for mobile computers, and failure isn't good because it can mean loss of data which can impact business productivity.
Hybrid drives on the other hand combine magnetic platter storage with a relatively large non-volatile solid-state cache. The key here is the non-volatile cache, which can store information when the spindle is spinning. This means data stored in the cache can be accessed instantly at startup, which results in faster boot and resume times for computers that use hybrid drives. Data in the cache can even be accessed when the spindle isn't spinning, and this means hybrid drives can work in a "low power" mode where the OS spins down the spindle and data is retrieved only from the cache. This low power mode typically utilizes only about 2% of the system's total power. Shock resistance is probably about the same between HDDs and hybrid drives however, so try not to throw your laptop against the wall when you get mad at your boss.
Not for every computer
One thing worth mentioning is that replacing the HDD of an existing computer with a hybrid drive may not always result in significantly faster boot times even if the operating system is optimized for hybrid drives (as every version of Windows since Windows Vista has been). This is because the BIOS comes into play here as well. Ideally, on a system that has a hybrid drive the BIOS should exit the POST stage of the boot process as quickly as possible. The BIOS should also be able to resolve the mappings between cache and disk before the drivers load. And of course the boot order in the BIOS should also be configured to boot from the hard drive first to avoid any further boot delays.
Should I use a hybrid drive or SSD?
Let's say you want to purchase a new desktop, laptop or server. Should you buy one with a hybrid drive installed or a solid state drive (SSD) installed?
It depends on your needs:
Where can I find some hard data?
A good place to look for raw benchmark data about the performance of hybrids and SSDs is Storage Review. For example, check out this review of the Seagate Momentus XT 750GB hybrid:
You can tell it's probably a good review when they actually take the thing apart piece by piece :-)

The following tip was submitted to us by Don, who is a CISSP working in Information Security at a university in Minnesota:
I was searching for information on anyone trying to find a way to get Port Reporter working on Windows 7 and Windows Server 2008. I finally gave up because no one has been able to. It just doesn't work and won't work until Microsoft updates the tool, which I doubt will happen.
I saw your article on using Port Reporter (on the O'Reilly website) to monitor network traffic. I realize that the article is 7 years old, so it isn't up-to-date. And I certainly agree with you that Port Reporter is a very useful tool….on XP or Server 2003. It comes in very handy for those OS's. But it doesn't work on anything else (I don't count Win2K because, after all, who still uses Win2K).
[Editor's Note: Here's a link to the article by me that Don is referring to:
The article is indeed old, but like soldiers it seems that old websites never die.]
I just thought I'd point out, in case people contact you looking for an alternative, that there is an effective alternative. Not one you would want to run 24x7 forever but one that is very useful for troubleshooting the cause of unusual network traffic. That is Mark Russinovich's Process Monitor (Procmon.exe). It monitors all activity related to processes, including network activity and logs it to a file for as long as procmon is running. So unlike snapshot tools like TCPView for Windows, it keeps a historic log of the activity that you can go back through to look for whatever network traffic, on the system in question, that you are trying to find. I just recently used it to track down some mysterious Apple traffic that a Windows box, with no Apple software on it, was generating out to a computer on Apple's presence on the Internet.
Of course, if you were to try and run it permanently (like Port Repoter), it would quickly eat up all your available disk space. But as a per incident troubleshooting tool, it works exceedingly well and does everything Port Reporter does.
[Editor's Note: You can download Process Monitor from the Windows Sysinternals site:

Here's a really fun book from O'Reilly that you can use to learn the basics of forensic science hands-on at home:
Illustrated Guide to Home Forensic Science Experiments: All Lab, No Lecture
The book is just one of several in their All Lab, No Lecture series. What I like about them is that the experiments aren't dumbed down in any way, they're accurate and the procedures are rigorous (to a degree) and well-detailed. Check out the above link and you'll see other titles from this series listed as well.
