The latest update to this is included here in the Final Reprise! EMC 20% Unified Storage Guarantee: Final Reprise

After all of the brouhaha and discussion from a recent post EMC 20% Unified Storage Guarantee !EXPOSED! I thought it valuable to dive a little deeper into our own calculator.

I’m sure like me, some of you may have tried to use the calculator and found it to be really cool, but you also may have experienced a few bouts of frustration.   It’s okay, I completely get it.  I get it so much that I’m writing this article to help reveal some of the challenges and how to overcome them.

For starters, one of the coolest bits about the EMC Unified Storage Capacity Calculator… is the fact it has a –help- option right there on screen.  I totally get it if you didn’t notice it, or feel you’re above ‘help’, I’m with you wholly! But I decided ‘Why not.. what does the “?” unveil? Wait for it… it unveils secrets to your success! And a breakdown of the ‘sauce’ so to speak!

When you first launch the Capacity Calculator for the first time, you should see a screen which looks like this – It defaults to a NX4 with nothing configured or set up.

Configuration and Templates

Regardless of which System Model you choose, NX4, NS-120, NS-480 or NS-960, the “?” help text for the NAS/SAN/Breakdown will be the same across the board.  Exceptions being that the help file will specifically declare whether you’re looking at a specific/respective model.   

As you start to fill the system with disks you may at some point come across an error such as ‘not enough space’, this will usually come up when you’re playing around with SAN configurations, or NAS (Custom) configs.    There is no need to be worried or alarmed when this happens.   All this is saying is that based upon the configuration you have ‘defaulted’ in the column/tab you’re working in, there is not enough “space” in that particular tray to add the disks.  

There are two ways to resolve this.    Either change to a disk format you can work with (Such as HS (Hot Spare)) as seen above, or using the arrows in the System Model diagram, you can move to another tray entirely!

System Models

What I find to be particularly useful and cool is the fact that when you select a particular system, hover over the “?” in the System Model section is that it will give you a breakdown of details about the system. (No more needing to go search the internet or call your TC asking “How many drives will my system take!?”  Not only that, but it also provides you with details of how you’d go about building this configuration – both in this simulator so to speak, and respectively when you go live with this as a real configuration.   Sweet if you ask me!

Total Usable Capacity

One particularly useful and cool bit about this is it not only tells you specifically what kinds of disks are required of the system, one particular complaint I’ve heard from some folks was about not knowing how many Spares were recommended in their configuration.  Well, check out the ‘caution’ symbol!

I built the following un-realistic configuration so we could drill down in to the system to see what it will report for ‘spares’ required.  Based upon this example, it looks like I need spares of every type, EFC, FC and ATA!    (I populated a tray of each type of disk to make this as unrealistic as possible :))  Pretty cool if you ask me!

But for the most part, this accounts for all of the ‘errors’, common or otherwise which I am noticing are encountered using this calculator.

Feel free to give it a good run through, but I’m so glad to see that a majority (read:all) of our concerns of how it operates and functions are actually solved right here in the help file! And in the case of SAN Custom Configuration (read:lack of templates) the little workaround for ‘lack of space’ above seems to address that in whole!

I hope you find the EMC Unified Storage Capacity Calculator to be as cool as I do, and that you get the best out of it!

Thanks and for those of you who haven’t played with the Celerra Virtual Appliance yet – Go download the Uber version here! Besser UBER : Celerra VSA UBER v2 (That’ll give you the ability to play around with the Celerra today without having to buy the hardware… nothing spells getting familiar than actually playing with a fully functioning system!)

Thanks, and good luck!

The latest update to this is included here in the Final Reprise! EMC 20% Unified Storage Guarantee: Final Reprise

So, I promised you guys in Iomega ix4-200d data reconstruction, ssh and more! that I would expose the password to login to the ix2 and ix4 as soon as I could.    Well, your wait is finally over!

Let’s start as you normally would, by logging into the support console!

http://192.168.1.1/support.html

Whoa, what’s that I highlighted there and even tossed in an arrow?! Can I MAKE it any more straight forward? Psst.. Click on Support Files :)

Ooh, what’s that little guy down there? Dump? Yea, I didn’t even notice this before (because I had shell access myself ;)) but this is for your benefit!

The system will go through "Gathering system state…"

Why yes, I did go mad with clicking colors and arrows in the win7 version of MSPaint.. Okay, but I digress. :)

Click that bad boy, which will include dump data about your system! Download it, and open it!

Drill down into the dump –> config –> etc –> and open up the file named “shadow”   (dump-20100107225620.tar.gz\dump-20100107225620\config\etc)

Find your shadow File in there, and lo and behold, you will have your Iomega root users hash!    Now it’s just a matter of cracking it!

It is beyond the scope of this article to tell you how to actually crack the pwd.. (giggle) go here, download john the ripper and you’ll do just fine :)

Taking my seed from my system and running it through a simple alphanumeric search, I come up with username root, password soho! That was easy! That works if you have NO Password set!

Through a collaborative effort with @randyjcress @Kiwi_Si @VirtualisedReal and @gabvirtualworld we were able to determine that by using soho and whatever password you use on the system, that should do it! And really, the credit does primarily go to @randyjcress for leading us in that specific direction so props randy! :)

ie: admin pwd is apples, so login using sohoapples – This is still undergoing verification, but I thought I’d share it out there, while we sort it out!

Disclaimer: The means to perform all of these tasks has been replicated and verified in the wild without requiring any intimate knowledge of the inner workings of the system. 

So for those of you who know me, you know I initially complained about a data reconstruction problem with my ix4-200d! I accidently pulled the power cable out (doh!) and then my system came up JUST fine, and said “Data reconstruction, 2%” Yea, it said that FOREVER – And it did nothing and got nowhere! Regardless of how many reboots I made! (Though my data access was fine!)

And even going to the “Update Device Software” tab, it always reported “The device software is up to date” Which I now know is a LIE! LIES I SAY! :)

I did a little searching and came across an updated firmware! (oh my!) however it didn’t say it’d do anything about data reconstruction problems! But hey, I always like to be running the latest/greatest, so I downloaded and installed the latest firmware! StorCenter ix4-200d Firmware Version 2.1.25.229: Read First (You’ll find this to be quick and painless!)

Well, some minutes passed and all of a sudden the system was all “DATA RECONSTRUCTION IS HAPPENING IN THE HIZZY!” Okay, not in those exact words.. but I don’t feel like pulling my power to try to reproduce the problem – needless to say, my data reconstruction resumed and finished in short order! Score one for the bucko! (dated reference much?!)

So I deep dove into the system to see what else had changed! (nothing consequential that I could find) but my journey to find a way to ssh this box had not ended! I was determined! I must.. I must.. I must increase my SSH ability! And while searching I came across not only this webpage SSH/Shell access to iomega StorCenter ix2 but that little gem of a webpage included this little link at the bottom! http://ip-of-nas/support.html – Which when you browse to it on your ix4, you end up seeing a page which looks like… this!

This has a few little gems, only two of which will I look at in any detail – Support Access and Recover Disks

Well, Support Access looks pretty damn straight forward! Check the box, reboot, and SSH will be enabled (permanently!)

The Storage Recovery Verification is a bit more interesting – my “guess” is that it allows you the ability to force the data reconstruction many of us complain of! Again, I have no intention of forcing the deal to try to see what happens if I fail my system – You simply let me know if this works for you – with data reconstruction woes :)

Sweet, eh! So, I feel comfortable sharing the process on how to do this.. because frankly, I had to find it from the outside looking in! So I definitely grant you good luck on solving your data reconstruction, firmware updating, and enabling SSH on your NAS!   Until I find an externally cited source though.. I cannot share with you my passwd I used to log in to my ix4 ;)

As promised!  Shell access to your ix2/ix4 exposed! “Get yer red hot ssh here!”

If you come across a site referencing it though, I’d be glad to add it to the mix!  Thanks for your patience.. and look forward to a future post around getting my ‘gigabit runs at 100mb’ problem :)

Welcome to the ix4-200d! This single device is a life changer for both the active home user as well as the SOHO business user who wants to take things to the NEXT Level!

If you’re not familiar with this little beast in a box, here are some of the high-lights which this brings to bear!   NFS, CIFS, iSCSI, AFP Support, BitTorrent client, Xbox Media Services, Printer, USB, Rsync, Celerra integration, dual gigabit Ethernet?!   Oh, and did I mention it’s –VMware- Certified out of the box?!?

Now, seriously! Let’s take a tour of this little system which has taken quite a step or integration in my household!

When I first powered this system up, it sat there for awhile without me doing anything to it.  Why? This thing is SILENT! I forgot I had powered it up, and as a result didn’t even bother to check what the IP address was that it assigned itself!   Well, out of the box, it came with a RAID protection I was fine with! I had options to change it, but I’m comfortable with it!

Frankly, this covers most of what you need to do with the device and you’re set! –Done!- But that doesn’t mean you need to stop there!

Most of the features in this unit can be configured by simply checking a box and poof! You’re done!

I have mine configured in the following fashion: AFP for my Macbook to backup, NFS and iSCSI for my ESX Servers, CIFS for local network file access, Media Services to interface with my Xbox360 to stream content and pictures, rsync Server to strangely replicate the box between this ix4 and an ix2 as well as to replicate over to the Celerra VSA :)   (Oh, and the Avamar Virtual Edition running in a VM backing up all of my home machines while taking up far less space with inline deduplication :))

I don’t have Video Surveillance enabled yet, but it’s nice to know the integration is built in there! (Printers also nice, but this lives in a closet, so I’m not sure I want to do that :))

So, hopefully you get the opportunity to play around with this power house in a box, and with the ix2-200d offering the same services (but with less disks and less IOPS) Oh, and if you’re interested in buying one, it’d help if you knew the “retail” costs!

So, that gives you an idea of “retail” cost, now I’d say, go to Fry’s and try not to pay more than $599.99 for the 4TB model (Fry’s is your friend! ;))

For another great review of this, check out Stephen Foskett’s review!

I’m sure by now you’ve read my introduction to RichCopy– Introducing RichCopy – your Robocopy replacement!  Well, today I spent some time doing speeds and feed tests over numerous protocols in my lab environment.  I want to establish a disclaimer that this is no way a reflection of the ‘speed’ you will get, or not get respectively – More that the sheer differences between single threaded operation (re:xcopy, robocopy, rsync for windows) will be infinitely improved when using this tool! Oh, and I’ll also go into some of the cool depth you can cover!

I ran a number of very small file copies (<4k file size files) in the 15,000 to 90,000 file range and got the following results!

The specific items I want to call out here are – when doing a single threaded copy (such as the CIFS job which took 57:16 – well, frankly that is as close to a ‘robocopy’ or ‘xcopy’ we’d get and when you compare it to slightly increasing the number of simultaneous threads – OMFG look at the results! Cut down by a lot of the time! Imagine if that were your production data migration – Cutting that seriously by 1/6th or even more depending upon the workload! The same can be said if you have ‘changed’ data that it is looking to update only the changed blocks.  So much potential!  This particular host was a slooooow VM which can somewhat explain why in general it was slow.  However the slowness is reflective across the board, so the 1/6th speed improvement is likely to be the same if not better in any other situation or circumstance! 

I definitely encourage checking it out, as well as the numerous advanced features this tool offers.

These advanced features… I’m going to discuss in a few moments as well ;)

For those of you who are new to RichCopy – Honestly you can get by with the simplest of actions by simply modifying your thread numbers.  But if you want to get into the special details of it, let me reveal to you a number of VERY cool functions and features.  Oh and might I add, ADVANCED features that let you take it up a notch, not to mention the amazing HELP file too!

Starting with the mothership of all functions! The Advanced option! Which enables a whole series of new options enabled when you go to your File Copy options!

The Process Control lets you really dive down into some functions such as your cache sizes and more! Really quite cool.  Though frankly as I jump to the “Others” section, one of the coolest features if the fact that when you modify your options in the GUI, you are presented with your CLI parameters!

Though don’t get me wrong, File Attributes, Error handling, inclusion and exclusions, FTP and other things themselves –are- quite cool!

Though hands down, the most important part of this tool is the fact that it EXISTS, it is FREE and it is fricking COOL!   So, there’s no reason to sit idly by paying for SecureCopy, or watching your serial operations SLOWLY move by as you migrate data! Get out there, and play around with RichCopy today! It’ll make you wish you had this tool for the past 10 years like MS had!
