GestaltIT Tech Field Day 2010: VBlocks Presentation

April 13th, 2010 No comments

This was surely the most debated discussion – presentation at the GestaltIT Tech Field Day 2010 in Boston, MA. Both the rock stars from the VCE team (Scott Lowe and Ed Saipetch) did the presentation and did an amazing job presenting on this topic.

Though I see a lot of value with the whole concept of VBlocks (VCE) towards the journey to the private cloud and means to compete with the Oracle’s, Dell’s, IBM’s and HP’s of the world, many in the crowd did not buy into this and thought was more of a marketing package without the necessary meat in it….

I am composing a post on VCE – Vblocks for release later this week, where will highlight many pros and cons of this technology based on what we heard and where we see the Vblocks architecture going.

Asked this same question to both Cisco and EMC during the UCS and VBlocks presentation as to how many customers are running UCS and VBlocks in production environments today, unfortunately got no answers. Three large customers I know of today, are practically using it in pre-production / test / development environments.

Here is the reaction from twitterville during and after this presentation.

GestaltIT Tech Field Day 2010: EMC – Vmware Vision

April 12th, 2010 No comments

The presentation on EMC – Vmware Vision was done by EMC – Chad Sakac, VP Vmware Alliance at EMC. Here Chad covers the issues around Storage efficiency, management, capacity and performance.

There was a 20 min piece where the cameras were turned off since the information is on embargo. Stay tuned related to that information later in the year. There is also some information that Chad discusses related to some new technology announcements from EMC and Vmware in the near future, product demostration, etc.

There were 15 delegates in the room from GestaltIT and around 12 to 15 from EMC including Barry Burke, Steve Todd, Chad Sakac, Rob Callary, Nick Weaver, Ed Saipetch, Gina Minks, Stu Miniman and many more.

GestaltIT TechFieldDay 2: The Delegates, the Presenters and the Technology Innovators

April 7th, 2010 No comments

GestaltIT TechFieldDay is being kicked off on Thursday 8th of April 2010, a two day event by GestaltIT. The pre event party is being hosted at the Hyatt in Boston, MA on Wednesday evening.

.

Previous post on TechFieldDay 2, here

So here are the delegates attending this event.

All the delegates come from different facets of IT and bring a varied background in terms of technology and experience. Most of the delegates focus around Storage, Virtualization, Servers, Networking and Enterprise IT. Being in the trenches they have learned a lot, want to share the experience and bring a unique perspective on what Enterprise IT is all about and possibly help address some next generation issues.

.

Here are the delegates with their own areas of expertise.

  • Virtualization Experts
  • Jason Boche
  • Carlo Costanzo
  • David Davis
  • Edward Haletky
  • Simon Long
  • Simon Seagrave
  • Gabrie van Zanten
  • Networking Experts
  • Greg Ferro
  • Storage Experts
  • Robin Harris
  • Greg Knieriemen
  • Bas Raayman
  • Not sure if I can call myself an expert…but sure storage centric
  • Enterprise Experts
  • Scott D. Lowe
  • John Obeto
  • Matt Simmons

Totally a very heavy focus on Virtualization this time around based on the heavy weight Virtualization experts we have in the team.

.

As for the Presenting Sponsors, here is the list of Companies we know so far that are attending

  • Cisco Systems
  • Data Robotics
  • EMC Corporation
  • HP
  • VKernel

And sure, many more non-presenting sponsors of dinner and GestaltIT parties.

.

So some of the technology we are looking forward to hear and talk about this week

  • Cisco Systems:
    • UCS, Nexus, Cisco OTV and Long Distance vMotion.
  • Data Robotics:
    • Drobo Elite, Drobo Pro and Drobo FS
  • EMC Corporation:
    • Unified Storage, Federation, vBlocks, VCE Acadia, FCoE, Symmetrix
  • HP Company:
    • IBRIX or now called the HP X9000
  • VKernel:
    • Optimization and Capacity Tools for VM environments

.

Be Prepared, if you are coming to the GestaltIT Tech Field Day and are on either side of the fence….

So after attending the Tech Field Day in San Francisco, CA late last year and having attended some Storage Tech days at HP, here is my advice to everyone either attending as delegates or presenters.

  • Expect hectic two and a half days
  • Be prepared for less sleep
  • Mental exhaustion
  • No time to blog
  • Network with fellow Delegates
  • Roundtable discussions
  • Record, Record, Record
  • Come armed with your Twittering and Blogging tools (Camera, Video Cam, microphone, batteries, memory sticks, etc…

Here is the post by the previous TechFieldday delegates, talking about being armed with all the necessary tools and the expectations with Techfieldday

.

For the presenters…

  • Stop the crap
  • Be heavily prepared
  • Give information that people are looking for
  • Expect the unexpected
  • Have answers ready, not let me get back to you

And if you are presenting, I would highly recommend reading this post by the previous TechFieldday Delegates, as to what is fair…

The technology innovators, I would highly recommend pick the brains of these invited delegates, get them to share some of their experiences, understand what they see in the industry, where they see things are headed, where they see issues, what they consider as your organizations positive and negative points. Share!! Share!! Share!!

.

So…………… are you ready for the action, tweets, technology talk, deep dives and an opportunity to learn more about Enterprise IT? The after effects of TechFieldDay are typically seen for weeks in form of twitter chatter, blog posts and vendor communication.See you all soon……delegates, vendors, presenters and technology innovators…

.

For the fellow twitter friends, you can follow me on Twitter @storagenerve, Twitter hashtag for GestaltIT Tech Field Day is: #TechFieldDay.

EMC Symmetrix: Calculations for Heads, Tracks, Cylinders, GB

March 22nd, 2010 No comments

Symmetrix Disk Drive

Here is the quick and dirty math on EMC Symmetrix Heads, Tracks, Cylinder sizes to actual usable GB’s of space.

Based on different generations of Symmetrix systems, here is how the conversions work.

Before we jump into each model type, lets look at what the basics are, with the following calculations.

.

.

.

.

There are s number of splits (hyper) per physical device.

There are n number of cylinders per split (hyper)

There are 15 tracks per cylinder (heads)

There are either 64 or 128 blocks of 512 bytes per track

.

All the calculations discussed here are for Open Systems (FBA) device types. Different device emulations like 3380K, 3390-1, 3390-2, 3390-3, 3390-4, 3390-27, 3390-54 have different bytes/track, different bytes/cylinder and cylinders/volume.

.

Symmetrix 8000/DMX/DMX-2 Series

Enginuity Code: 5567, 5568, 5669, 5670, 5671

Includes EMC Symmetrix 8130, 8230, 8430, 8530, 8730, 8830, DMX1000, DMX2000, DMX3000 and various different configurations within those models.

GB = Cylinders * 15 * 64 * 512 / 1024 / 1024 / 1024

eg: 6140 Cylinder devices equates to 2.81 GB of usable data

6140 * 15 * 64 * 512 / 1024 / 1024 / 1024 = 2.81 GB

Cylinders = GB / 15 / 64 / 512 * 1024 * 1024 * 1024

Where

15 = tracks per cylinder

64 = blocks per track

512 = bytes per block

1024 = conversions of bytes to kb to mb to gb.

.

Symmetrix DMX-3/DMX-4 Series

Enginuity Code: 5771, 5772, 5773

Includes EMC Symmetrix DMX-3, DMX-4 and various different configurations within those models.

GB = Cylinders * 15 * 128 * 512 / 1024 / 1024 / 1024

Eg: 65520 Cylinder device equates to 59.97 GB of usable data

65540 * 15 * 128 * 512 / 1024 / 1024 / 1024 = 59.97 GB

Cylinders = GB / 15 / 128 / 512 * 1024 * 1024 * 1024

15 = tracks per cylinder

128 = blocks per track

512 = bytes per block

1024 = conversions of bytes to kb to mb to gb

.

Symmetrix V-Max

Enginuity Code: 5874

Includes EMC Symmetrix V-Max and various different configurations within this model.

GB = Cylinders * 15 * 128 * 512 / 1024 / 1024 / 1024

Eg: 262668 Cylinder device equates to 240.47 GB of usable data

262668 * 15 * 128 * 512 / 1024 / 1024 / 1024 = 240.47 GB

Cylinders = GB / 15 / 128 / 512 * 1024 * 1024 * 1024

15 = tracks per cylinder

128 = blocks per track

512 = bytes per block

8 bytes = 520-512 used for T10-DIF

1024 = conversions of bytes to kb to mb to gb

Drive format on a V-Max is 520 bytes, out of which 8 bytes are used for T10-DIF ( A post on DMX-4 and V-Max differences).
