FAST (FULLY AUTOMATED STORAGE TIERING)

FAST made a debut in the storage market yesterday (12/08/09). Finally after the market buzz we got a preview of the product in terms of its features, functionality, characteristics, possible shortcomings and use cases.

This blog post focuses on the features, the drawbacks and some applications around FAST.  By no means is this a comprehensive or an exhaustive list of the above.

After all, FAST makes a debut, (The previous post on FAST).

Imagine the possibilities of FAST with this infrastructure

Imagine the possibilities of FAST with this infrastructure

NOTE: Out of the box thinking by EMC, imagine the flexibility one would have with a large infrastructure and FAST moving data based on policy. Its all about the big picture.

..

..

Here are some features, highlights of FAST and how it operates.

  • FAST will perform data movement based on IOPS, average I/O size and write percentage. This is currently true for the Symmetrix V-Max, Clariion CX4 and Celerra NS.
  • Three elements that define FAST: Storage Type, FAST policies and Storage Groups.
  • FAST is based on user defined – configuration policies.
  • The configuration of FAST is typically done through FAST wizards (Symmetrix Management Console) on Symmetrix V-Max, FAST LUN Migrator for Clariion CX4 and Rainfinity File Management Appliance or VE for Celerra NS.

  • User defined analysis period for FAST. That will enable FAST to recommend or perform data analysis and then a data move based on policy.
  • FAST created policies will associate with Storage Groups.
  • FAST policies will be configurable at a LUN / drive / drive type / speed etc level.
  • Data movement will take place based on a time of the date policy called “COLD” move or on usage policy called “HOT” move.
  • Data movement will take place between various drive types, various LUN types and LUN sizes. (LUN types, LUN sizes will need to be same for the source and destination LUNs). For example a 9GB FBA LUN being migrated from Fibre to FLASH will need similar source and destination LUN properties.
  • FAST data analysis will be performed in the background.
  • For Symmetrix V-Max platform FAST will perform all analysis without the use of Symmetrix Performance Analyzer. Understanding is there will be some sort of API plugin available on the Service Processor of the V-Max that will enable Symmetrix Management Console (FAST plugin) to interface with the Symmetrix through the SYMAPI interface.
  • For Clariions, the performance data of the array will be monitored and collected by Navisphere Analyzer.
  • Based on the source LUN analysis, FAST will recommend the user to move the data either a faster speed drives or a slower speed drives.
  • FAST will enable roll back based on user preferences (automated).
  • FAST will be configurable by Symmetrix Management console wizards or SYMCLI
  • FAST configurable by Clariion Naviseccli and installed on a host connected to Clariion, Host software called FAST LUN Migrator.
  • FAST configurable by Rainfinity File Management Appliance GUI or CLI for Celerra NS “out-of-box data” movement. This enables the Celerra to move data to another Celerra or Centera or Atmos.
  • FAST configurable by Rainfinity File Management / VE (Virtual Appliance) for Celerra NS “in-the-box” data movement.
  • FAST can be installed non-disruptively on all platforms.
  • FAST will operate both at an FBA and CKD level supporting open systems and mainframes for V-Max.
  • FAST will operate at a LUN level on Symmetrix V-Max
  • FAST will operate at a LUN level on Clariion CX4
  • FAST will operate at a file level on Celerra NS
  • FAST v1 users will be able to purchase a FAST v2 upgrade when it’s released in second half of 2010.
  • FAST can be purchased as a FAST suite or part of an ATSM (Advanced Tiering Storage Management) suite with bundled discounting prices.
  • For a unified storage system like a front end NAS (Celerra) with a backend SAN (Clariion), FAST can coexists at both levels. But it is not recommended to deploy FAST at a Celerra LUN level.
  • FAST integrates with Symmetrix Management Console and with Rainfinity GUI (Celerra) for simple management. Though Clariion implementation will need one to specialize in CLI.

FAST Drawbacks

Here are some drawbacks of FAST as I see it today.

  • Does not support Virtual provisioning. So the Virtual provisioned LUNs will not be FAST enabled. Sub-LUN expected in second half of 2010
  • FAST is not free and is charged based on RAW CAPACITY of the Storage Array.
  • FAST will only work with similar LUN types (example FBA LUNs can be migrated to FBA) and LUN sizes (9GB LUN can be migrated to a 9GB LUN) only.
  • FAST will require Professional Services and is not recommended for customer self implementation at least for the Clariion and the Celerra platforms. EMC is making a claim that FAST can be self provisioned on the Symmetrix V-Max platform.
  • FAST works only on current generation systems like EMC V-Max Enginuity 5874, Clariion CX4 Release 29 and Celerra NS.
  • With Clariion CX4 and FAST implementation, requirement is to have Navisphere Analyzer.
  • With Celerra NS and FAST implementation, requirement is to have Rainfinity File Management /VE or Appliance.
  • With Symmetrix V-Max FAST implementation, requirement is to have Symmetrix Management Console (Not free any more starting with the V-Max)
  • For the Clariions, FAST only analyzes Fibre drives and LUN movement has to initiate from Fibre channel to FLASH or Fibre channel to SATA drives only. Movement from FLASH to Fibre or SATA to Fibre has to be initiated manually.
  • A customer implementing Virtual Provisioning on Clariion CX4 and Symmetrix V-Max that is using 50% Thick Provisioning and 50% Virtual Provisioning. FAST will not work with Virtual Provisioned LUNs. But the customer will probably pay for 100% of Storage Raw Capacity when it comes to paying for FAST either non-bundled or bundled in an ATSM (Advanced Tiering Storage Management).
  • FAST does not support IBM System I platform currently.

Some real world FAST applications

vBlock

vBlock

  • Acadia Service Model can now add granularity with offerings around on-demand resources using FAST at its core.
  • On Demand application and workload needs can be met for OLTP, Data Warehousing, Mainframe compute and Virtual compute using FAST driven policies.
  • Multi-tenancy with Private Clouds
  • Move high demand data on faster drives while rarely used data goes on slower drives.
  • Sell ITaaS based on SLA’s. Higher SLA’s can mean higher price. All automated processes controlled by policy.
  • Higher transactions typically mean low overall cost; mean higher efficiency means higher profits all achievable through FAST policy engine.

Need to see some real world implementations of FAST now. In theory and on paper, FAST looks pretty compelling but practically will it do the magic.

..

..

Some unanswered questions today

  • How does it prevent from LUNs jumping between Fiber, FLASH and SATA if the application has un-expected performance that day?
  • Manageability of FAST interfaces.
  • Usability of FAST interfaces.
  • Granular configuration policies associated with analysis.
  • Future upgrades.
  • Current implementations and how long and how effective are those.
  • Can you improve performance without using SSD’s. Example with Fibre and SATA drives only.
  • With future upgrades from FAST v1 to FAST v2 what happens with current user defined policies.
  • Would Symcli scripts change with FAST implementation?
  • During lockout periods (Where Symmetrix configuration cannot change, eg before a BIN file change) would FAST still operate.

..

FAST is a bit of a new subject for me. Any experts please feel free to correct me if my understanding of FAST is incorrect at any level.

Stay tuned for a series of FAST posts over the next few days talking about various topics and how FAST plays within those areas.

After all, FAST makes a debut

December 8th, 2009 4 comments

So EMC has proved critics like me wrong and have introduced EMC FAST (Fully Automated Storage Tiering) as an offering in Dec 2009. There were many skeptics like me that saw this product release being stalled because of various reasons, here.

FAST (Fully Automated Storage Tiering)

FAST (Fully Automated Storage Tiering)

Truly this was one of the most awaited products of 2009 from EMC after the initial announcement by EMC back in April 2009 along with the release of Symmetrix V-Max.

I have dedicated a separate deep-dive section for EMC FAST on the StorageNerve Blog, here

Along with FAST, EMC has also introduced some new enhancements to the EMC Symmetrix V-Max, Clariion CX4 and Celerra NS platforms. Currently FAST will be available on the above 3 platforms at debut and will provide automated storage tiering “in-the-box” for Symmetrix V-Max, “in-the-box” for Clariion CX4 and “out-of-box” for Celerra NS platforms.

As expected EMC has not made this feature free but rather offers a pricing model based on bundled software. FAST will be an available feature within ATSM: Advanced Tiering Storage Management bundle and will be charged based on RAW Capacity of the Array (Symmetrix, Clariion and Celerra)

FAST will not be supported on EMC DMX-4 and Clariion CX3. In essence FAST is only compatible with EMC Symmetrix V-Max Enginuity Microcode 5874.xxx.xxx and Clariion CX4 Flarecode Release 29.

FAST is a software only feature and integrates with existing hardware / software on the associated platforms.

The following are some of the features FAST will support at GA on the EMC Symmetrix V-Max, Clariion CX4 and Celerra NS platforms.

EMC Symmetrix V-Max

Symmetrix V-Max Data Movement

Symmetrix V-Max Data Movement

  • Volume / LUN based data movement (Automated Storage Tiering) for open systems and CKD – mainframe volumes.
  • Management of FAST through Symmetrix Management Console or SymCLI
  • Data Movement can be accomplished between FLASH, fibre channel and SATA drives within the V-Max platform. Data can move in any direction and on any type of the drives based on policy.
  • Data movement within a single frame or serial number only.
  • FAST suite can be purchased as a standalone software suite but will be available at a discounted price based on a bundled option with Symmetrix Optimizer, DCP: Dynamic Cache Partitioning and SPC: Symmetrix Priority Controls.
  • Symmetrix Performance Analyzer will be required for FAST to operate on Symmetrix V-Max platform. (Based on the comment from Barry Burke below, Symmetrix Performance Analyzer is not required for FAST to operate on the Symmetrix V-Max platform.

EMC Clariion CX4

Clariion CX4 Data Movement

Clariion CX4 Data Movement

  • LUN based data movement (Automated Storage Tiering)
  • Management of FAST will be enabled through CLI only. Not supported as an integrated part of Navisphere today.
  • Will work with Flarecode Release 29 (Clariion CX4) only.
  • Unlike the Symmetrix, the automated data movement will only be supported between fibre channel drives to FLASH or fibre channel drives to SATA. There is no automation related to data movement from FLASH to fibre channel or FLASH to SATA or SATA to FLASH or SATA to fibre Channel drives.
  • Data movement within a single frame or serial number only.
  • FAST suite can be purchased as a standalone software suite but will be available at a discounted price based on bundled option with Navisphere Analyzer and NQSM: Navisphere Quality Service Manager.
  • Navisphere Analyzer is required for FAST to operate.

EMC Celerra platform

Celerra in the box data movement

Celerra in the box data movement

Celerra in the box and out of box data movement

Celerra out of box data movement

  • File based data movement (Automated Storage Tiering)
  • Management of FAST can be accomplished through Rainfinity file management appliance GUI or CLI. Customers also have an option to purchase Rainfinity File management/VE (Virtual Appliance), which has some limitations.
  • Data movement can be enabled to another tier “in-the-box” or to another Celerra or Centera or Atmos.
  • Celerra FAST is most interesting as it enables out the system data movement, like to another Celerra or Centera or Atmos.
  • FAST suite can be purchased as a standalone software suite but will be available at a discounted price based on a bundled option with Rainfinity File Management Appliance or Rainfinity File Management /VE.

Based on EMC heat index charts, a before and after picture of a FAST implementation would look like this.

Here is a post, back from August 2009 on Gestalt IT describing how EMC’s Unified Storage vision and federation may work. It is good to see, some of those things come to fruition now, and at least FAST with Celerra proves it.

Stay tuned for a series of FAST posts over the next few days talking about various other topics and how FAST plays within those areas.

GestaltIT Techfieldday 2009: Post 8 (Day 1)

November 16th, 2009 No comments

Today marks the first day of the two day GestaltIT Techfieldday 2009. As described on previous blog posts, this is a very unique event and will be an industry trendsetter. A very nice blog post by John Troyer from Vmware describing GestaltIT #Techfieldday and the wave it is creating in the industry, here

We had an action filled day today, 18 hours of non-stop techno-geek talk so far.

Vmware

The day started early morning today at 7 AM, we all left to go to Vmware first, where Xsigo Systems and MDS Micro were presenting. Expectations with both these presentations were very high, and they absolutely managed to deliver on it.

Met up with John Troyer first at Vmware headquarters in Palo Alto, CA. The bus took us from the hotel to Vmware and will be the means of transportation throughout the event. After a great breakfast this morning, they gave us a tour of the Vmworld DataCenter – Lab (hundreds of VM’s running within a single cabinet with Clariion, Xsigo, MDS running as a Converged Infrastructure).

IMG00187-20091112-0816


Then we went for a walk around the Vmware campus to another building where the event was being hosted. Walking there, we ended up taking some funny pictures…

Then Stephen Foskett took the stage to present us on the concept of GestaltIT TechFieldday 2009. He then passed on the mic to John Toor from Xsigo Systems who explained us the agenda for the rest of the morning.

MDS Micro

MDS Micro took the stage and went through the entire set of technical marketing presentation on the MDS Micro set of products and how the blocks compete in a converged infrastructure. Quite a compelling story from MDS.

Then Vmware took the stage next, the group called GETO (Global Engineering Technical Operations). These are the guys that worked on designing the Datacenter at Vmworld 2009. On a dinner table in Florida, they created the concept of the next datacenter at Vmworld 2009. Amazing 45 min technology talk.

Xsigo

Then Xsigo took the stage. Wow…..what a presentation, Cam Ford from Xsigo was on the stage, this guy has a passion and believed in what he was presenting. I was really really impressed.

At times its just not only walking up to the stage and presenting on a technology, believing in something and presenting the technology is completely different. That is exactly what we saw with this presentation. Tons of questions were asked and Cam Ford was able to answer each one of them……..Loved the techno talk. I am now believing that Xsigo will in a short duration be a take over target. They have a great technology in their hands.

IMG00196-20091112-1150

3Par

Had lunch at Vmware and then we all headed to 3Par. Now after the Xsigo presentation, we were expecting a lot from 3Par.

Craig Nunes, Marc Farley and John D’Avolio were at the 3Par lobby to receive us as we reached to their headquarters.

We were looking for the famous Pooja Desai – the “Check it out Girl” from the StorageRap Videos and the joke @edsai made on the Infosmack – Storage Monkeys – Vmware Wrap up Podcast.

3Par brought in Siamak Nazari on the stage to talk about various 3Par technologies.

This guy was amazing!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

One thing I would like to emphasize again, please make sure all the presenters for the GestaltIT #techfieldday are technology experts. We need to talk to “the best of the breed”, I have typically seen based on all the presentations at GestaltIT Techfieldday and HPTechday so far that the engineering / technical marketing folks have been very well received amongst the audience. There are aways people in the group ready to chew the presenter if they are not aware of the technology they are presenting on.

Siamak Nazari started the presentation and within a few mins, had questions from the audience, but he started going into details, white boarding, diagrams, explaining chunklets, buses, clusters, software, architecture and he won everyone in the room. This presentation was scheduled for about 45 mins, but by the time the presentation was done, we were well over 90 mins.

Its hard to write about the technology in one blog post and will not be fair to 3Par and its technology. So what i will do is provide you all with a detailed architectural overview of the 3Par technology over next couple of weeks, showing a video of the presentation and the architecture around the 3Par clusters.

Siamak Nazari wanted to go into a lot of details, but i believe since this was a non NDA session, the folks in the room had to stop him going into architecture and futures.

Then Craig Nunes along with Marc Farley presented on the 3Par Thin Technology and Zero Page reclaimation. I truly believe they have a great team of people there that are driving the product.

IMG00197-20091112-1512

IMG00198-20091112-1737

We then went to the 3Par Test and Development labs. This lab has to at least be warehousing about 200 to 300 3Par systems. At times it is great breathing the data center air…..

Symantec

Then Symantec took the stage with its Storage Foundations suite. Some nice technical chat around filesystems, how Symantec integrates with 3Par for Zero page reclaimation, how customers can drive the storage they already have in data centers with the use of Storage Foundations suite. There were quite a few questions asked and contradictions made in this presentation, where the GestaltIT Bloggers didn’t understand the complete strategy of Symantec in relation to Storage Foundations product. Though from my perspective I felt it was a complete solution but not a lot of market applicability.

GestaltIT Party

We then left there to head to the Computer history Museum in San Jose for the GestaltIT Party. What a crowd of people there. This event was sponsored by TechValidate (Brad O’Neil’s new venture). Tons of people from various Tech PR companies, HP, Nirvanix, 3Par, Vmware, Data Robotics, Ocarina Networks, Bhava Communications, MDS Micro and many more were present.

Met up with Murli, CEO from Ocarina Networks, he is just a magnificent personality. Very humble and approachable. Met up with Brad O’Neil and many others from the Storage industry.

IMG00202-20091112-2026

Then was the video presentation by Sunshine Mugrabi and Marc Farley as a tribute to Stephen Foskett. This is a great video.

The Bar

We then headed back to the hotel…..the night was just beginning. At the bar, people were just dissecting everything that they had heard today and putting it into perspective.

Around 2 AM in the morning the night finally finishes (at least for me) and looking forward for a new day tomorrow, more TECHNO-GEEK talk to continue…..

My eyes are barely staying up now, All I can say is Goodnight!!!!!!!
