SFF-8484 to 4 x SATA Cables

I just purchased a Dell PERC 5/i (basically an LSI 8404) RAID card off eBay and I needed to purchase two SFF-8484 cables to connect it to my SATA hot swap bays.

There seems to be a great deal of confusion on eBay from vendors that have these cables — many of the vendors just don’t know what they have; and it’s important to know, since there are two different cables fitting the general description — and they are not interchangeable.

The cable I needed could be identified by a Trip Lite part number S502-01M or an Adaptec part number 2167000-R (discontinued) or a StarTech part number SAS84S450.

The description should contain the key phrase that the cable is used to attach a SAS (or SATA) HBA (Host Bus Adapter) to individual SATA drives.  The description should not mention anything about hooking up a SATA controller to a SATA/SAS back plane.

What’s the difference in the cables???

Well, the SAS controller to SATA device cable is straight through; the SATA controller to SAS back plane has the RX and TX swapped… and generally speaking there’s not a lot of call for the SATA controller to SAS back plane so those will be the least expensive, and the most prevalent on eBay.

The sellers who do know what they have, and advertise it as such want a phenomenal price for the cables (they’re only $19.99 on Amazon, buy the two you’ll need and they ship free)…

Do your home work and ask your questions before you commit to buy on eBay — particularly if it’s from China or Hong Kong (it’ll take several weeks to get the item, and returning it will be half the price you paid).  While Amazon’s gone down hill a great deal recently; it’s still easy to return, and in the long run you might save both time and money.

Color Nook

Barnes and Nobel showed it’s color Nook Tuesday in San Francisco – the press seems to like it; 15.8 oz, 7” screen, 8GB storage (plus uSD slot), WiFi, uUSB power, Android based…  available for pre-order on 19 Nov.

Not clear that you have access to Android marketplace, but it sounds like it (since there were references to installing games and such on it)… this could be real competition for the iPad (and the Kindle).

ASUS Eee PC

ASUS has release a series of “thin client” devices that they call the Eee PC, it comes in three basic models (the Eee PC Surf and Eee PC look identical, but the Surf versions apparently aren’t easily upgraded; and then there’s the Eee PC 900 which has a larger display).

The Eee PC Surf is available with either 2GB or 4GB; the Eee PC is available with either 4GB or 8GB — both have a 7″ screen.

The Eee 900 is available with either 12GB (Linux) or 20GB (Windows) and has a 8.9″ screen.

All of the use Intel processors… for more information just go to ASUS, and I’ll save you the pain of going through their cute presentation:

ASUSTek Computer Inc (Asus)

This is from one of my friends, send to Teresa Perdue ( tsd@asus.com.tw ) of ASUSTek Computer Inc ( http://www.asus.com.tw/ or http://usa.asus.com/ ).

I’d considered buying an Aus Eee PC… but I think I might be happier with a sub-notebook from one of their competitors.

I’ve removed the personally information (except for Teresa’s).

Teresa,

Thank you for informing my that my motherboard is out of warranty and that you will not replace then fan.

In my opinion, this is not a warranty issue.  Warranties generally protect one from a product that happens to be bad.  Most reputable companies replace any item that is poorly designed or has an unusually high failure rate regardless of the warranty period.

I would like for you to know that I am very disappointed with Asus.  On your website you even say that the original fan did not work properly.
Also, there are numerous forums on the Internet that talk about the problem s with the AN8SLI chipset fan.

I have already had one Asus motherboard fail because of a chipset fan that failed.

I have probably built about 100 computers in the last ten years almost all of which used Asus motherboards.  It now seems that you are having quality control issues and that I will have to use a different brand of motherboard in the future.

I have just ordered two fans from your eStore.

Please understand that it is not the cost of the fans that is an issue.  My total charge, including shipping, is $22.00 which is insignificant.  What is significant is that I have learned that I cannot rely on Asus to replace faulty products.  I am unwilling to risk purchasing products from a company that doesn’t stand behind the quality of their workmanship.

This email is being copied to all of the other system builders with whom I work and will be copied to all system builder forums to which I belong.

Sincerely,

XXXX XXXXX

Promise NS4300N NAS (Update)

Looks like Promise has “fixed” the issue with Seagate 1.5TB drives in the NS4300N NAS…

They’ve replaced Compatibility List NS4300N_SR5_Compatibility_List_v1.0-20081031.pdf with NS4300N_SR5_Compatibility_List_v1.0-20081126.pdf on their support web site — the never revisions of the V1.0 Compatibility List omits the Seagate 1.5TB drive (interesting that they choose to call it V1.0 rather than V1.1 and remove the previous V1.0 list from their web page)… but the firmware release notes still contains the statement that they’ve added support for 1.5TB drives (the only 1.5TB drive I know of is the Seagate).

Promise’s actions are a little suspect… maybe it’s time for a trip over to Alameda’s Small Claims Court…  I’ve retained copies of both versions of the compatibility list as well as the firmware release notes.

And for the record, I have still yet to receive any update to my online support inquiry even though I’ve updated it a number of times with “additional” comments and information; and I’ve called Promise as well.

Computer Tid Bits

I haven’t sent one of these tid bit emails out in a long long time — this is just a collection of little points that you might find comes in handy.

Server 2008 is indeed out and available. I think I’m going to wait a few months (and I’m just about out of funds for MSFT store purchase, so doubtful I can get a copy for anyone else — I’ll probably do the MSDN OS subscription again). Hyper-V has not shipped as of yet.

Service Pack 1 for Vista can be downloaded or you’ll get it from Windows Update. If you’re updating more than a single machine, download the whole thing (Windows Update will swamp your connection). There are separate packs for 32-bit and 64-bit (you may need both if you have both machines). Also, copy the update file to the local disk (it will need elevated privileges to install).

Virtual Server 2005 R2 can be installed on XP, XP-64, Vista-32, or Vista-64. The management interface requires IIS, so that’s a little different with PWS version on non-server platforms. If you have VS installed on a server, you should be able to manage _all_ of your installations from one management interface (though Vista doesn’t make that easy).

Google GMail allows you to host your domains for email there for free… you basically get GMail accounts in your own domain. I’ve moved my mail services over there for the time being (I still archive all my email on my own server at home, but the active send/receive is done via GMail).

Parallels is coming out with a new server (64 & 32 bit) to compete with Hyper-V; I looked at the beta (definitely a beta, but useable), they may be able to get some of the market share — but my guess is they’ll get the share from VMware (I didn’t care for the Mac-ish look of the product on Windows).

2.5″ SATA disk drives continue to fall in price; Seagate 250GB drives were $104 @ Fry’s, and they still had some on the shelf on Monday!!!

Intel hasn’t release the most of the 45nm processor family yet; the older Core2 dual and quad processor continue to be a great buy. Remember that really none of the current Intel chip sets take advantage of the higher transfers the newer processors are capable of (well the X38, but that’s supposed to have major issues) — so you might want to wait for the next generation of Intel chips and motherboards to hit the market. FYI: Intel delayed the release because AMD missed their ship dates… their new cores had some rather serious flaws

Notebook and desktop memory are nearly on par with each other. You can purchase 2 x 2GB for under $100 (easily — even the really fast memory). $60 is actually the low price and $80 get’s you high quality with heat spreaders (notebook memory doesn’t have heat spreaders — no room). 2 x 1GB can be purchased for $40!!!

Tablet Wars

A long time ago in a galaxy far, far away…

Not really — and it doesn’t have much impact without a score playing — but, that doesn’t take away from the fact that the Apple iPad appears to have sparked an all out battle for control of the tablet market.

A number of “new” tablets (and tablet prototypes) are being shown, some with a price tag as low as $199!!!

Maybe the competitors won’t be quite as “slick” as Apple’s iPad, but they’re all guaranteed to be more powerful, more affordable, and more open.

Hackers

I’ve noticed that here lately my SSH server has had an increasing number of hackers trying to log in.  Mostly they’re from the APNIC (Asia-Pacific) region, but a fair number from other regions (include North America) as well.

Since I have no plans to travel abroad in the near future I went ahead and blocked out all IP addresses registered through any registrar except ARIN, and I also added several hosting companies that seem to to have customers that either don’t secure their servers well or they themselves launch cyber attacks.

It’s generally a good idea to make sure that any server that can be used to gain entry to your network is as secure and limited as possible.  Obviously you don’t want to go overboard and make it impossible for you to do what you need with relative ease; but that said, you don’t want to make it easy for others to do things to your computers.

Microsoft Streets and Trips 2008 with GPS and Connected Services

I picked up a copy of Microsoft Streets and Trips 2008 with GPS and Connected Services; basically the package includes the same Pharos (re-branded) GPS module that Microsoft has been using along with a Pharos (re-branded) FM side-band receiver (similar technology as to what you can get on a number of all-in-one GPS units that provide real time data).

I haven’t tried all the wizzy new features for real yet, but in service areas I should be able to get real time data on traffic, construction, gas prices, weather, etc… the real question is how well S&T uses that data to auto-magically re-route.

I have a Pharos all-in-one GPS-150 receivers that’s a nice little unit, but it’s difficult to enter address information (there is not a sync to the PC option), and it doesn’t get real time data feeds. The Pharos all-in-one uses their Ostia software rather than Streets and Trips; but you can hack Tom-Tom PDA software to run quite nicely on it (the problem is getting the maps).

__________

A bit of trivia for those that don’t know the connection between the word “Pharos” and mapping / navigation. Pharos was the name of the light house at Alexandria, Egypt. And “Ostia” was the ancient port of Rome at the mouth of the Tiber river.

Vista Activation

Over the past couple weeks I’ve had to “reactivate” two copies of Vista; now I did update the video cards and the optical drive (which is likely what triggered it), but interestingly enough, these are the two oldest copies of Vista (the first two computers installed with it).

It’s not difficult…

You try the online activation, it fails.

You call the automated telephone activation system, it fails.

You request a transfer to a Microsoft activation specialist, you read them the codes, answer a couple simple questions, and they give you the activation code which you type in and then you’ve activated.

Hopefully my activation is good for another twenty months (or more)!

NOTE:  While I’m sure that changing the hardware triggered this, I suspect that Microsoft has implemented a more rigorous inspection of the computer fingerprint to defeat bulk copies of Vista by questionable computer manufactures.
