Remote Desktop Manager, by Devolutions

March 10th, 2010

No te acostarás sin saber una cosa más, si Señor.

Estaba yo tan contento, preparando mi post de este jueves (éste, si, éste) y pensaba que versaría sobre una herramienta que me ha dado muchos alegrías. Hablo de Mremote, una herramienta que hace de cónsola / Shell para RDP, VNC, SSH, HHTP y alguno más.

En un proyecto me han pedido especial hincapié en tener una herramienta de este tipo, y buscando por esas webs de Dios, me encuentro con esta maravilla, Remote Desktop Manager by Devolutions, que encima es Freeware.

Integra los siguientes clientes: RDP and TS, MS Remote Assistance, Real VNC, TightVNC, UltraVNC, Citrix,LogMeIn, Team Viewer, Dameware, VMware Player, Workstation, vSphere, Hyper-V, Virtual PC, Virtual Server…. Add-ons para HP graphics, y SQL studio …. me dejo alguno que te interese? pues seguro que me lo he olvidado y seguramente está disponible. Increíble

Se puede hacer download aquí , bajas el .msi y lo instalas como un “my wife”, Al arrancar no te asustes, no te pide licencia, tan sólo te pide si lo quieres arrancar en modo Standard (Freeware) o Enterprise (de pago, básicamente con gestion de usuarios y soporte para SQL Server, Amazon S3, Multiusuario, etc). Obtendréis una vista como ésta.

Remote Desktop Manager

Pero no terminan aquí las sorpresas. “File, Import, Import from another application, mremote” . Pues sí, te vas a tu Mremote que tienes funcionando, exportas un XML de la configuración de las conexiones y te lo importas a tu nuevo entorno (algún cambio tendrás que hacer, no todo es tan “directo”.

Aquí podéis ver el impresionante “pop up” de configuración con las herramientas que podemos integrar

Remote Desktop Manager

Pero fijaros la lista que tiene especificamente para virtualización

Rmote Desktop Manager

Recordad que hay que instalar los clientes en la máquina donde vais a ejecutar la cónsola, y si no sabéis donde encontrarlos, en la pagina de download de la aplicación están los links necesarios, mas fácil imposible.

Le ha llegado la hora a mi fiel Mremote veo. Hasta la semana que viene.

Whats going on in VMware View land part II

March 10th, 2010

Mucho going on in View (and more generally VDI) land.   My first part I was posted here.

If you’re interested in a quick catch-up, read on…

View 4.5 beta

The existence of this has been discussed by others (here, and here) – I will neither confirm nor deny.   What I can say is that the ongoing march of improved simplicity, scale, function in the hosted virtual desktop use case is well underway, and that every day, more and more customers are starting to embrace it.

I’m part of the internal EMC View 4 pilot rollout.   For me personally, Windows 7 and check-in/out is a huge deal (and neither supported in View 4).  Then again, I wouldn’t describe me as the idea target user (at least right now) for Client Virtualization (as an extremely mobile laptop user, who is also constantly building my own environment – I’m using Office 2010 beta also right now as an example).

That said – expanding the use cases out to these types of users are very important.

I do use it all the time – but not as my primary machine.   How do I use it?  The vSpecialist team uses View as the front-end to much of our demo lab gear.

If you want to hear about our own experiences with View 4 in our internal rollout – their was a recent EMC IT webcast which was recorded.  You can see that here.

VMware View Launch Tour

The VMware View/EMC Launch tour is coming to a city near you… I should have posted this earlier, as there were dates I missed, but there are several left in Canada and the US.    You can register here.

The “who’s better for View vendor histrionics” continue…

At Partner Exchange – my colleagues from NetApp claimed that “9 of 10 customers using VDI use NetApp” .  As you can imagine, that caused some eyebrows to be raised.  Vaughn reiterated that claim recently at Mike Laverick’s blog/”chinwag” here… (35 minutes in)  as well as making some comments about me (calling me “Rupert Murdoch” for hiring good folks, and EMC the “Evil Galactic Empire” about 10 minutes in :-) 

BTW, correcting one comment in the recording – as EMC, I can’t hire from partners who are focused and committed EMC partners.  But I will also say this – people are the thing that make the world go-round, and I’m certainly OK about taking top-notch people from competitors and competitive partners!

Vaughn is good guy, and you can hear that in Mike’s podcast (which I would recommend listening to).   He and I are both passionate about virtualization, and love our gigs.  I personally agree with almost everything he said, particularly around “stack”… and disagree vehemently with the characterizations about me and EMC, View market share, and implying that the VCE Coalition (integrated tech, selling, support, and joint venture) and the partnership between Cisco and NetApp are equivalent.  but then again, you’d probably expect that :-).

First things first… there is no data (none) to support the NetApp claim.   I was going to let it go and not respond publicly, but it keeps getting broad up, so…

While I think NetApp has great technology, and a strong View go-to-market, this claim didn’t sound right to me, so I pinged the View product team.  Their comments:

"based on our VDI run rate and overall VDI market size, also supported by what we are hearing from our software partners, we don't see how this can possibly be true."

On a similar thread, I also ran into several customers in Southern California who were told by NetApp that “VMware runs their internal production View deployment on NetApp”.   This is also not correct.  If anyone would like to the VMware IT folks about what they deploy internally, I’m happy to arrange that discussion.

NetApp has solid solutions and is a fine company – I don’t think they need to do these things.  I suppose in some way it’s effective, as it forces me/us to spend time correcting things.

IO scaling in the VDI use case

More on this front… The question of IO scaling point is very real, particularly at larger scales (thousands of clients) and came up at the two biggest financial customers in NYC who I visited last week 

To recap: "while the focus on VDI storage costs tends to focus on $/GB (as people are not knowledgeable about storage in general think in “GB”), the question of cost of configuration that supports the IO load through the lifecycle of the client community is often governed by many factors – including BOTH capacity and performance  as well as functional use cases”.

Vaughn’s posted on his blog here some comments about the VMware Express van (the van itself is very cool – I would highly recommend checking it out if you can).   I think it was interesting to see the comments in response to the thread.  

Personally, I was blown away by the claim Vaughn initially made about “12U, two disk shelves, 5000 users”

So, just like any extreme claim (like the incorrect statements in the section above above), I did some digging.   I happen to know the fellow in the VMware GETO team he was talking to, and I asked him.   His comment:  “we currently have enough *compute* capacity to run around 5000 desktops”.  He also took umbrage at being taken so out of context, but I won’t post the rest of his comments as they weren’t nice :-)

I did also personally followup with Vaughn – as a statement implies that 28 disks could support 5000 VDI seemed… “off”.  

To understand why they seemed “off”, quick back of napkin math assuming the users drive 10 IOps on average, and assuming a 50/50 read/write mix, that’s  25,000 random read and 25,000 random write IOs per second coming into the storage array.   Assuming no magic (and there is some magic) between the host and the back-end disks (this is the most conservative assumption) – this would mean each of those disk drives is able to do 1785 random IOps :-)   This is about 10x the amount you would expect them to do.   Array magic can make the backend do more than it should be able to do with no magic.

So, let’s talk about array magic.   

  • Caching techniques… To understand cache better (in a generic “across vendors” way) I would highly recommend this post, which is correctly title “Storage Caching 101”).    These get positioned furiously as magic that solves everything. 
    • Read cache can help, but only help in some of the desktop’s life-cycle –in the view case, the biggest win is in reading the common blocks of the boot disks.  Vaughn points out in his post a partner’s data (here) that shows a ~38% improvement in the bootstorm case based on dedupe and PAM.   Conversely, read cache help far less for things that are more random (remember that a read-cache doesn’t help on the first read, only on the second).  So – read cache impact on patching, far less.  Reading the more random elements (apps, OSTs, far less).  
    • Write cache can help in the VDI use case, particularly in absorbing periodic bursts.
    • Greater cache efficiency comes from a) more efficient caching algorithms which squeeze more utility out of the same amount of cache; b) deduplication/compression of blocks in the array means you fit more of them into the read cache; c) deduplication of the files above the array (aka composition techniques) mean that the base replica only points to a small number of blocks, meaning they fit into the read cache – aka View Composer or Xen Desktop mean that the read cache on most current midrange arrays can contain the bulk of the boot data; d) application of very large, low-cost cache models.
  • Write Caching means you can coalesce and restructure IO patters…  When the host I/O write is decoupled from the array actually writing the IO, a bunch of optimizations can happen.  
    • Restructuring IO patterns: the amount of “randomness” can be reduced if you accept that back-end structure and the front-end structure don’t match.   The idea of “Locality of Reference” (LoR) is slowly dying out – thin-provisioning schemes, deduplication, and journaling mechanisms (which transmogrify the IO pattern to try to maximize sequential magnetic media performance).  Are there still cases where having the host “view” of blocks and the array “actual location” being related helps?  Sure, but it’s a declining set, and some of the disadvantages of ditching LoR (performance losses in narrow use cases that are sequential read dominated) tend to overrule the advantages (large cost savings).   It’s handy if you can do both, but that usually comes at the cost of more operational complexity.
    • Coalescing:  as write IOs come down from the host, the write cache means they can be “batched” from smaller (think 4-8K) host IOs to larger (think 64-1MB) backend IOs, reducing the backend effect.

All arrays have technologies that apply in varying cases to the above.

After the outreach about the number of disks, Vaughn asked some of his technical folks and they ran it through the NetApp sizing tool for VDI.   His correction on the post (thank you, Vaughn – and BTW, there have been times where Vaughn has corrected me – like he found an error in our VM alignment docs that got fixed) is that for a 4IOps/user, 50/50 (read/write mix), the configuration would need 56 spindles, not 24.   I’m assuming these were 15K drives.   

I will note that 4IOps per user is much lower than I’m seeing in practice.    In practice, I tend to see 8-15 per user, and it’s not unusual to see 25 at peak…. But – let’s continue with an assumption of 4.   If it were larger, the number of drives just scales up.

This makes more sense, as that number translates to 357 IOps per drive (4 per user, 5000 users, divided into 56 drives).  This is something to be proud of because absent “array magic” max for a 15K drive would be around 180 IOps – so if they can get 360 “effective IOps” that’s a 2x improvement.   Of course, I want to note that the calculations involve no RAID loss considerations.

If a vendor (NetApp or EMC – we do seem to be the ones most focused on the VDI use cases) says they can do a 2x “array magic” reduction in IO in their processors that sit between the host and the spindles, lean forward and listen.  Poke at it a lot – because 2x is still a big number, but listen.   If they claim 10x “array magic”, walk away slowly – they are dangerous to you as the customer, and themselves as the vendor :-)

Here’s my advice:

  • Step 1. Figure out how much you need for your performance envelope,
  • Step 2.  THEN figure out the capacity angle (drives * capacity/RAID loss * capacity efficiency gains that come from user data dedupe/VMDK compression/thin and more) and see if you need more.   

There’s a certain break-point where configurations tend to be capacity-gated vs. performance gated.  

Then, go through and look at the cost-to-serve a desktop with that given configuration.

When you go through that process, I’m confident that EMC’s VDI solutions can prove competitive cost-to-serve-a-client (that and functional use cases, and availability requirements).  I know because I (and my team) do it every day.

BTW – the way (IMO) to achieve order-of-magnitude capex improvements are to:

  • Spend a little time profiling your users.   You can use VMware Capacity Planner.   I dig a tool from LiquidwareLabs for this purpose (does a lot more, but is not free).   You’ll save a lot of money by doing a LITTLE up front design.   knowing this answer is critical to Step 1.
  • increase the user density per blade (this is one of the largest economic drivers in scaled-up view use cases as it affects all factors, including VMware licensing).   Today, this means optimizing around RAM per blade for the most part.
    • In the near future, an order of magnitude improvement may be possible by placing vSwap on SSD – expect more support for this from VMware later this year.   If confused, think of how much it costs to put 128GB of DRAM in a blade.   Then, lookup the price for a consumer 256GB SSD.   Then, do the math, and extrapolate to mid-summer.   If further confused, read this post.   Note that vswap on local SSD performed almost as well as no overcommit.
  • Look if you can apply composition and application virtualization techniques – while impacting how you deploy and manage your clients, this is a huge win on both capex and opex, even if you apply it to just SOME of your users.
  • Put user data on cheap, deep, deduped, compressed, SATA-based NAS storage.   Offload anti-virus to that platform, and use that to make archiving and backup orders of magnitude cheaper.
  • Apply VMware’s guest best practices.   These can take you from 25 IOps per guest to 10 by making simple, and free changes (silly little things like turning off guest defrag and disk layout optimization, and making swap a fixed size, and avoiding vswap – if not using SSD :-)

Then, move on to “tens of percentages” optimizations.

  • Leverage read cache to deal with mass reads against the same blocks.
  • Leverage write cache to let the array do some magic, but remember that you must be able to sustain the baseline steady state load (or even long bursts).
  • Squeeze out more by putting the base replica on EFD.  If your array can auto-tier, this will happen automatically.   If not, future View composer releases will allow you to put the base replica in one datastore, and the linked clones in another.
  • At the end of this process, further capacity savings for VMDKs may apply via VMDK dedupe and compression.

Remember – whether it’s VMDK block level dedupe (which regularly shows 90% capacity savings), or VMDK compression (which shows 40-60% on top of thin), the question isn’t how much capacity is saved, but rather how much the total configuration costs, and the $/VM, physical space/VM and so on..)   You should challenge every vendor (this certainly applies to EMC) to express the solution in those types of metrics.   Not in any given feature.

Here’s data from lab analysis of the effect of the base replica being on EFD…

 

image

Here’s data from a customer (in this case a Citrix case of user.dat files where behavior is governed by CIFS operations per second, but applies similarly to the View use case).   Here we have an NS-960 with 5 EFDs, compared with the older NS-80s with 20 15K drives.

image

Not only were the NS-960s able to sustain 80K CIFS Op/Sec (which is a LOT) -  the EFDs were able to do 33x more random IO per backend spindle, and do it with a 1.5ms response time rather than 93ms response time at the filesystem level observed on traditional 15K RPM disks.

I hate to be so pedantic about this topic (VDI storage design), but it’s important to me for the reason I mentioned back in this post.   This IO density question is the number 3 reason I see View projects not starting (#2 being total TCO; and #1 being client experience), and #1 reason why they go sideways in late stage scale-up.  Bunch of interesting startups here – Atlantis and others….

These two blog posts discuss this in good detail and additional perspectives:

It’s OK to disagree but please be civil about it

March 10th, 2010

I see it frequently on Twitter, here’s an example:

  • Vendor A - Our product does this and supports this, Vendor B’s does not
  • Vendor B - Oh yeah well our product does this and this and your product doesn’t
  • Vendor A - Your product is way behind ours, you have a lot of catching up to do
  • Vendor B - Then why are so many people using our product, our product is the best

If you’re on Twitter you’ve probably experienced this first hand, you also see it on blogs. Vendors that are rivals frequently bait each other by making claims that there product is better in one way or another. Of course the other vendor can’t resist this challenge and takes the bait and you have a back and forth debate that usually gets nasty and that all of us must experience while each vendor tries to throw punches and claim victory. This kind of non-professional banter has no place in a professional business. Everyone is vulnerable to this, I’ve even seen C-level executives get caught up in this. You may think that you are only defending your company and products when you respond to this kind of stuff but to everyone else that is watching you go back and forth it seems very childish and benefits neither vendor. Because of this kind of behavior you almost have to question who to trust and who to believe, vendor A or vendor B. Some people may choose to trust neither vendor because of the mudslinging and go with vendor C instead.

If you really want to sell your products and impress people try taking the higher ground when challenged by another vendor. Yes we know you are proud of your products as you should be and believe them to be the best but arguing with and insulting other vendors in public forums is not the way to prove it. Instead use your websites or blogs to inform those who are interested why your product is good and why they should buy it. There is a damn big pool of customers out there and plenty of room for multiple vendors to thrive. I do not work for a vendor and I can tell you from my personal experience that seeing that kind of immature behavior makes me not want to deal with that vendor regardless of how good their products are. On the other hand I have a great deal of respect for vendors that take the higher ground and act in a classy manner.

So vendors, knock it off, please act professional and people will notice and more importantly will listen to you. You may not like your competitors but at least respect them, they’re trying to make a living just like you are. Vendors that have mutual respect for their rivals get real high marks in my book and that type of friendly, non-confrontational  interaction between vendors is productive and very beneficial to all. Now I’m not saying you shouldn’t debate your points on social media, I like a good debate and can learn from it as long you keep it civil and professional. Just try and remember that we’re all professionals and try not to get caught up in the heat of the moment and lash out in a insulting or derogative manner at someone who challenges you. The people reading and following you will take notice and you will score higher marks than getting caught up in a Twitter piss-match. Social media is a wonderful tool when used correctly, when used incorrectly though it can really hurt your business. I really enjoy the great information that I gather on social media, so lets keep it civil so everyone enjoys what you have to say.
