EMC 20% Unified Storage Guarantee !EXPOSED!

May 20th, 2010

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

For those of you who know me (and those who don’t, hi! Pleased to meet you!) I spent a lot of time at NetApp battling the storage efficiency game, always trying to justify where all of the storage space went in a capacity bound situation.   However since joining EMC, all I would ever hear from the competition is how ‘space inefficient’ we were and frankly, I’m glad to see the release of the EMC Capacity Calculator to let you decide for yourself where your efficiency goes.   Recently we announced this whole "Unified Storage Guarantee" and to be honest with you, I couldn’t believe what I was hearing. So I decided to take the marketing hype, set it on fire and start drilling down into the details, because that’s the way I roll. :)

EMC Storage Guarantee

I decided to generate two workload sets side by side to compare what you get when you use the Calculators

I have a set of requirements – ~131TB of File/Services data, and 4TB of Highly performing random IO SAN storage

There is an ‘advisory’ on the EMC guarantee that you have at least 20% SAN and 20% NAS in order to guarantee a 20% space efficiency over others – So I modified my configuration to include at least 20% of both SAN and NAS (But let me tell you, when I had it as just NAS.. It was just as pretty :))

Using NetApp’s Storage Efficiency Calculator I assigned the following data:

Storage Efficiency Calculator

That seems pretty normal, nothing too out of the ordinary – I left all of the defaults otherwise as we all know that ‘cost per TB’ is relative depending upon any number of circumstances!

So, I click ‘Calculate’ and it generates this (beautiful) web page, check it out! – There is other data at the bottom which is ‘cut off’ due to my resolution, but I guarantee it was nothing more than marketing jibber jabber and contained no technical details.

Storage Efficiency Calculator

So, taking a look at that – this is pretty sweet, it gives me a cool little tubular breakdown, tells me that to meet my requirements of 135TB I’ll require 197TB in my NetApp Configuration – that’s really cool, it’s very forthright and forth coming.

What’s even cooler is there are checkboxes I can uncheck in order to ‘equalize’ things so to speak. And considering that the EMC Guarantee is based upon Useable up front without enabling any features! Let me take this moment to establish some equality for a second.

Storage Efficiency Calculator

All I’ve done is uncheck Thin Provisioning (EMC can do that too, but doesn’t require you to do that as part of the Guarantee, because we all know… some times… customers WON’T thin provision certain workloads, so I get it!)   Also turning off deduplication, just so I get a good feel for how many spindles I’ll be eating up from a performance perspective – And turning off dev/test clone (which didn’t really make much difference since I had little DB in this configuration)

Now, through no effort of my own, the chart updated a little bit to report that NetApp now requires 387TB to manage the same workload a second ago required 197TB. That’s a little odd, but hey, what do I know.. This is just a calculator taking data and presenting it to me!

Now… with the very same details thrown into the EMC Capacity Calculator, lets take a look at how it looks.

image

According to this, I start with a Raw Capacity of ~207TB and through all of the ways as defined on screen, I end up with 135TB Total usable, with at least 20% SAN and about twice that in NAS – Looks fairly interesting, right?

But lets take things one step further. Let’s scrap Snapshots on both sides of the fence. Throw caution in to the wind.. No snapshots.. What does that do to my capacity requirements for the same ~135TB Usable I was looking for in the original configurations.

clip_image005[4]I updated this slide to accurately reflect more realistic R5 sets for the EFD disks.  In addition I introduced an ADDITIONAL spare disk, which should 'hurt' my values and make me appear less efficient.

On the NetApp side I reclaim 27TB of Useable space (to make it 360TB Raw)- while on the EMC side I reclaim 15TB of useable space [150TB Useable now] while Still 207TB Raw.

But we both know the value of having snapshots in these file-type data scenarios, so we’ll leave the snapshots enabled – and now it’s time to do some math – Help me as I go through this, and pardon any errors.

Configuration NetApp RAW NetApp Useable Raw v Useable % EMC RAW EMC Useable Raw v Useable % Difference
FILE+DB                
Default Checkboxes   197 TB 135 TB 68% 207 TB 135 TB 65% -3%
Uncheck Thin/Dedup   387 TB 135 TB 35% 207 TB 135 TB 65% +30%
Uncheck Snaps   369 TB 135 TB 36% 207 TB 150 TB 72% +36%

However, just because I care (and I wanted to see what happened) I decided to say "Screw the EMC Guarantee" and threw all caution to the wind and decided to compare a pure-play SAN v SAN scenario, just to see how it’d look.

clip_image007[4]

I swapped out the numbers to be Database Data, Email/Collaboration Data – The results don’t change (Eng Data seems to have a minor 7TB Difference.. Not sure why that is, – feel free to manipulate the numbers yourself though, it’s negligible)

clip_image008[4]

And I got this rocking result! (Yay, right?!) 202TB seems to be my requirement with all the checkboxes checked! But this is Exchange and Sharepoint data (or notes.. I’m not judging what email/collab means ;))… I’m being honest and realistic with myself, so I’m not going to thin provision or Dedup it any way, so how does that change the picture?

clip_image009[4]

It looks EXACTLY the same [as before]. Well, that’s cool, at least it is consistent, right?

However, doing the same thing on the EMC side of the house.

I want to note a few differences in this configuration – I upgraded to a 480 because I used exclusively 600GB FC drives as I’m not even going to lie to myself that I’m humoring my high IO workloads on 2TB SATA Disks – If you disagree you let me know, but I’m trying to keep it real :)

RAID5 is good enough with FC disks (If this was SATA I’d be doing best practice and assigning RAID6 as well, so keeping it true and honest) And it looks like this:

image

(Side Note: It looks like this SAN Calculation has only 1 hot spare declared instead of the 6 used above in the other configuration – I’m not sure why that is, but I’m not going to consider 5 disks as room for concern so far as my calculations go – it is not reflected in my % charts below – FYI!  I fixed the issue and introduced 6 Spare disks.  I also changed the system from 14+1 R5 sets to 4+1 and 8+1 R5 sets which seems to accurately reflect more production like workloads :))

Whoa, 200TB Raw Capacity to get me 135TB Usable? Whoa, now wait a second. (says the naysayers) You’re comparing RAID5 to RAID6 – that’s not a fair configuration because there is definitely going to be a discrepancy! And you have snapshots enabled too for this workload. (Side note: I do welcome you to compare RAID6 in this configuration, you’ll be surprised :))

I absolutely agree – so in the effort of equalization – I’m going to uncheck the Double Disk Failure Protection from the NetApp side (Against best practices, but effectively turning the NetApp configuration into a RAID4 config) and I’ll turn off Snapshot copies to be a fair sport.

clip_image011[4]image

There, it’s been done. The difference is.. That EMC RAW Capacity has stayed the same(200TB) while NetApp raw capacity has dropped considerably by 30TB from 387TB to 357TB. (I do like how it reports "Total Storage Savings – 0%" :))

So, what does all of this mean? Why do you keep taking screen caps, ahh!!

This gives you the opportunity to sit down, configure what it is YOU want, get a good feel for what configuration feels right to you and be open and honest with yourself and said configuration.

No matter how I try to swizzle it, I end up with EMC coming front and center on capacity utilization from RAW to Usable – Which down right devastates anything in comparison. I do want to qualify this though.

The ‘guarantee’ is that you’ll get 20% savings with both SAN and NAS. Apparently if I LIE to my configuration and say ‘Eh, I don’t care about that’ I still get OMG devastatingly positive results of capacity utilization. – So taking the two scenarios I tested in here and reviewing the math..

Configuration NetApp RAW NetApp Useable Raw v Useable % EMC RAW EMC Useable Raw v Useable % Difference
FILE+DB                
Default Checkboxes   197 TB 135 TB 68% 207 TB 135 TB 65% -3%
Uncheck Thin/Dedup   387 TB 135 TB 35% 207 TB 135 TB 65% +30%
Uncheck Snaps   369 TB 135 TB 36% 207 TB 150 TB 72% +36%
                 
EMAIL/Collab                
Default Checkboxes   202 TB 135 TB 67% 200 TB 135 TB 68% +1%
Uncheck Thin/Dedup   387 TB 135 TB 35% 200 TB 135 TB 68% +33%
Uncheck RAID6/Snaps   357 TB 135 TB 38% 200 TB 151 TB 76% +38%

When we’re discussing apples for apples – We seem to be meeting the guarantee whether NAS, SAN or Unified.

If we were to take things to another boundary, out the gate I get the capacity I require – If I slap Virtual Provisioning, Compression, FAST Cache, Auto-Tiering, Snapshots and a host of other benefits that the EMC Unified line brings to solve your business challenges… well, to be honest it looks like you’re coming out on top no matter what way you look at it!

I welcome you to ‘prove me wrong’ based upon my calculations here (I’m not sure how that’s possible because I simply entered data which you can clearly see, and pressed little calculate buttons… so if I’m doing some voodoo, I’d really love to know)

I also like to try to keep this as realistic as possible and we all know some people like their NAS only or SAN only configurations. The fact that the numbers in the calculations are hitting it out of the ballpark so to speak is absolutely astonishing to me! (Considering where I worked before I joined EMC… well, I’m as surprised as you are!) But I do know the results to be true.

If you want to discuss these details further, reach out to me directly (christopher.kusek@emc.com) – or talk to your local TC (Or your TC, TC Manager and me in a nicely threaded email ;)) – They understand this rather implicitly.. I’m just a conduit to ensure you folks in the community are aware of what is available to you today!

Good luck, and if you can find a way to make the calculations look terrible – Let me know… I’m failing to do that so far :)

!UPDATE! !UPDATE! !UPDATE! :)  I was informed apparently every thing is not as it seems? (Which frankly is a breath of relief, whew!)

Latest news on the street is, apparently there is a bug in the NetApp Efficiency Capacity Calculator – So after that gets corrected, things should start to look a little more accurate, let me breathe a sigh of relief around that, because apparently (after being heavily slandered for ‘cooking the numbers’) the only inaccuracy going on there [as clearly documented] was in the source of my data.

However, being that I’m not going to go through and re-write everything I have above again, I wanted to take things down to their roots, lets get down into the dirt, the details, the raw specifics so to speak.  (If any thing in this chart below is somehow misrepresented, inaccurate or incorrect, please advise – This is based upon data I’ve collected over time, so hash it out as you feel :))

NetApp Capacity GB TB EMC Capacity GB TB GB Diff TB Diff % Diff
                   
Parity Drives 4000 3.91   Parity Drives 4000 3.91 0 0

Raw Capacity 28000 27.34 Raw Capacity 28000 27.34 0 0  

What I’ve done here is take the information and tried to ensure each one of these apples are as SIMILAR as possible.

So you don’t have to read between the lines either, let me break down this configuration – This assumes 28 SATA 1TB Disks, with 4 PARITY drives and 1 SPARE – in both configurations.

If you feel that I somehow magically made numbers appear to be or do something that they shouldn’t – Say so.   Use THIS chart here, don’t create your own build-a-config workshop table unless you feel this is absolutely worthless and that you truly need that to be done.   

You’ll notice that things like Parity Drives and Hot Spares are identical (As they should be) Where we start to enter into discrepancy is around things like WAFL Reserve, Core Dump Reserve and Aggr Snap Reserve – Certainly there are areas of overlap as shown above and equally the same can be said of areas of difference, which is why in those areas on the EMC side I use that space to define the CLARiiON OS and the Celerra OS.    I did have the EMC Match the default NetApp Configuration of a 20% vol snap reserve (on the EMC side I call it Check/Snap Reserve) [Defaults to 10% on EMC, but for the sake of solidarity, what’s 20% amongst friends, right?]    (On a side note, I notice that my WAFL Reserve figures might actually be considerably conservative as a good friend gave me a dump of his WAFL Reserve and the result of his WAFL Reserve was 1% of total v raw compared to my 0.07% calculation I have above, maybe it’s a new thing?)

So, this is a whole bunch of math.. a whole bunch of jibber jabber even so to speak.   But this is what I get when I look at RAW numbers.   If I am missing some apparent other form of numbers, let it be known, but let’s discuss this holistically.     Both NetApp and EMC offer storage solutions.    NetApp has some –really- cool technology.  I know, I worked there.   EMC ALSO has some really cool technology, some of which NetApp is unable to even replicate or repeat.   But before we get in to cool tech battles, as we sit in a cage match watching PAM duel it out with FAST-Cache, or ‘my thin provisioning is better than yours’ grudge matches.    We have two needs we need to account for.

Customers have data that they need to protect.   Period.

Customers have requirements of a certain amount of capacity they expect to get from a certain amount of disks.

If you look at the chart closely, there are some OMFG ICANTBELIEVEITSNOTWAFL features which NetApp brings to bear, however they come at a cost.   That cost seems to exist in the form of WAFL Reserve, and Right sizing (I’m not sure why the Right Sizing is coming in a considerably fat consideration when contrasted with how EMC does it, but it apparently is?)  So while I can talk all day long about each individual specific feature NetApp has, and equivalent parity which EMC has in that same arena; I need to start somewhere.  And strangely going back to basics, seems to come to a 23% realized space savings in this scenario (Which seems inline with the EMC Unified Storage Guarantee) Which frankly, I find to be really cool.  Because like has been resonated by others commenting on this ‘guarantee’, what the figures appear to be showing is that the EMC Capacity utilization is more efficient even before it starts to get efficient (through enabling technologies).

Obviously though, for the record I’m apparently riddled with Vendor Bias and have absolutely no idea what I’m talking about! [disclaimer: I have no idea what I’m talking about when I define and disclose I am in this post and others ;)]   However, I’d like to go on record based upon these mathematical calculations, were I not an employee of EMC, and whether I did or did not work for NetApp in the past, I would have come to these same conclusions independently when presented with these same raw figures and numerical metrics.   I continue to welcome your comments, thoughts and considerations when it comes to a Capacity bound debate [Save performance for another day, we can have that battle out right ;)]  Since this IS a Pureplay CAPACITY conversation.

I hope you found this as informative as I did taking the time to create, generate, and learn from the experience of producing it.  Oh, and I hope you find the (unmoderated) comments enjoyable. :)   I’d love to moderate your comments, but frankly… I’d rather let you and the community handle that on my behalf.   I love you guys, and you too Mike Richardson even if you were being a bit snarky to me. {Hmm, a bit snarky or a byte snarky… Damn binary!}  Take care – And Thank you for making this my most popular blog-post since Mafia Wars and Twitter content! :)

Farewell, but not goodbye! (Transitioning from NetApp to EMC)

September 7th, 2009

September 4th, 2009 was a beautiful yet fateful Friday.   The sky was clear, lunch was good, and it also happened to be my last day working at NetApp.

Yes, it was my last day at NetApp – breaking up is hard to do, and this was a particularly challenging breakup!

I didn’t have the opportunity to send a formal farewell message to folks internally, so this will serve as my farewell (but not goodbye!)NetApp Teamwork Award

For those of you who don’t know, I worked for NetApp in the Chicago District – Yes, this is the very same Chicago district who recently won Teamwork Award across all of the Americas in the hardest Q4 most businesses had to deal with in their entire business!   So, it goes without saying that I had the opportunity of working with a cohesive family which embodied teamwork.

 

Fortunately, I worked with, met and interacted with so many intelligent and passionate individuals, the entire experience of working for Fortune magazine’s #1 best company to work for was an absolutely great, engaging and rewarding experience like no other.    In the short time (2 years) I was with NetApp I have seen extraordinary change, the ecosystem of business and the economy go on a rollercoaster adventure.   Never once did these individuals stray, but instead stepped up to the occasion and became better for their actions.   I know in my stead, this trend will continue and I look forward to seeing the growth within the community over the passage of time.

So, while I will miss you all – this is only farewell, but not goodbye.  Fortunately the community we’re all a part of is a receptive and growing one.  Our paths will cross continually and growth and self-development will always be an agenda we all pursue.   My community involvement will not shrink, and likely will continue to increase.  And my communication back out of offers to the technology community as a whole (whether those be discount vouchers, opportunities, so on and so forth) will continue to flow like a tapped pool of knowledge!

I’m sure given the circumstance many of you may be interested in why I made this particular decision.   Know that through heavy calculation, this was chosen as the best decision for me and my family at this particular stage in my life, and is in no way a reflection of the absolutely amazing organization I am walking away from to the equally amazing organization I am going towards.  

I am particularly excited about the new role I will starting on September 14th, 2009 (My Birthday of all days!)   Yes, while this may read as though it is a rebirth; starting a new job on my birthday, I will be certain to bring the same level of passion, engagement and enthusiasm that every one of you who has ever met me is likely to recall. :)

The next chapter of my life will be living the rock star life of a Senior Technology Consultant at EMC, continuing my trend of raising awareness, education, doing the right thing, evangelizing and informing the Enterprise IT community.     I know what you’re saying “Wow Christopher, you’ve held one consulting role or another for the past 20 years” Damn straight skippy! A consultant is strangely what I grew up knowing and being, and the evangelist side of things is just a further extension of my adopted religion (Re: Facebook Religion status is listed as Technology:))

I will continue to be actively involved in giving back to various technology communities.   Within the Exchange community (there’ll be more to say on that soon ;)), within the Chicago Microsoft space in general (Chicago Windows Users Group), the global Microsoft space (TechEd) and the Training Community (MCT Summits, etc).  I encourage you to reach out to me through any of these avenues, not to mention LinkedIn, Facebook, Twitter, (vouchers ;)) and any number of random Security, Cloud and Virtualization events as they come up! (Oh, email is fine too :))

So, I wish every one of you I’ve had the opportunity to work with, customers, partners and colleagues alike the best! Do keep in touch and let me know how things are with you, and I’m glad to help in the various ways I can and do help within the community!    And to my future customers, partners and colleagues – I look forward to the opportunity to work with you!

Best of luck, I appreciate all of the encouragement and continue to look for good things from me… :)

TechEd09 Partner Night (Or: Dude you’re getting heckled by Dell)

May 17th, 2009

If there’s one thing about TechEd in my experience (Apparently, my experience isn’t everyones experience.. infact, I’m not sure ANYONE else experiences this ;)) is that it is a whirlwind adventure of constantly being on the run, on the go, and occasionally… getting heckled by the competition (Erk, can I call that ‘product’ competition? We don’t sell Laptops and Dell doesn’t sell storage [snicker ;)] :)

I like business cards, as they’re a good way to stay in touch with people you’ve met, definitely, right? Oh and Twitter, that’s good for it too.     But what if you don’t have any business cards? (ran out on the 1st day;)) I adopted the model of taking a photo of you and your badge.. Win?!

Because I wouldn’t want to publish anyone’s image and name without their permission, I’ll instead give you this one! (and this lovely story.. strangely retold many times throughout the show by others ;))

image

Meet mr Dell Guy, I didn’t catch his name (too blurry) but he definitely caught that I work for a competitor (Hey, I’m here as an attendee!) was my common response when assaulted! Even though I did have a number of lengthy and high quality NetApp related conversations, I had just as many good quality Education and Community conversations too.   But you don’t care about that! You care about the heckling! :)

Being at the front of the line, literally in the front as a drawing is called is always a good way to find out if you’re a winner, or… if you’re going to be publicly called out on.   Oh and a competitor being mic’d to a large crowd yelling out NetApp every other word, perhaps that is just good times. ;)

For what it is worth, I did not win the laptop they were giving away (Which mr Dell did say “You can’t win!”) as I scoff being a mere ‘attendee’ :)  Although if you’re interested I did win Flip Mino Ultra from Cisco (Notice Cisco in the background) – I’ll discuss that later in another story ;)

I wish I had more time to get around and enter into drawings or try to win mega-big prizes, but it was not in the cards.. I barely could pack all the swag I DID end up taking home, so no harm no foul! :)
