Will 6Gb SAS kill Fibre Channel?

Storage I/O trends

With the advent of 6Gb SAS (Serial Attached SCSI) which doubles the speed from earlier 3Gb along with other enhancements including longer cable distances up to 10m, does this mean that Fibre Channel will be threatened? Well, I’m sure some conspiracy theorist or iSCSI die hards might jump up and down and say yes, finally, even though some of the FCoE cheering section has already arranged a funeral or wake for FC even while Converged enhanced Ethernet based Fibre Channel over Ethernet (FCoE) and its complete ecosystem completely evolves.

Needless to say, SAS will be in your future, it may not be as a host server to storage system interconnect, however look for SAS high performance drives to appear sometime in the not so distant future. While over time, Fibre Channel based high performance disk drives can be expected to give way to SAS based disks, similar to how Parralel SCSI or even IBM SSA drives gave way to FC disks, SAS as a server to storage system interconnect will at leat for the forseeable future be more for smaller configurations, direct connect storage for blade centers, two server clusters, extremely cost sensitive environments that do not need or can afford a more expensive iSCSI, NAS let alone an FC or FCoE based solution.

So while larger storage systems over time can be expected to support high performance 3.5″ and 2.5″ SAS disks to replace FC disks, those systems will be accessed via FCoE, FC, iSCSI or NAS while mid-range and entry-level systems as they do today will see a mix of SAS, iSCSI, FC, NAS and in the future, some FCoE as well not to mention some InfiniBand based NAS or SRP for block access.

From an I/O virtualization (IOV) standpoint, keep an eye on whats taking place with the PCI SIG and Single Root IOV and multi-root IOV from a server I/O and I/O virtualization standpoint.

Ok, nuff said.

Green, Virtual, Servers, Storage and Networking 2008 Beijing Olympics

Storage I/O trends

How about those opening 2008 Beijing Olympic ceremonies on NBC last night?

If you were like me, I had my DVR capture the event while out enjoying the nice August evening with some friends doing some relaxing and fishing (we did catch and release fish!) on the scenic St. Croix river.

The reason I bring up the Olympics, servers, storage, networking, virtualization and green topics are a couple of themes. One being all the news and content available to keep track of what is happening with the games taking place all of which is being stored on servers, storage and relying on networks to access the rich media and unstructured data via the web or traditional media. The 2008 summer games are also being described as the on-line and virtual olympics. The amount of storage being used to store digital data from the 2008 Olympics for later playback, which then gets recorded on DVRs if not watched in real-time is staggering as are the number of servers and networking capabilities being used. In addition to the video, audio, still photos, text and blogs, then there are the security cameras in Beijing generating massive amounts of digital data.

For those who track or keep an eye or ear open towards data and storage management, the amount of data that continues to grow and number of copies that get created should be a familiar theme. Of course, you would then have heard that the magic elixir is to simply de-dupe everything. That is reduce your data footprint by eliminating all of those extra copies however easier said then done, especially when a copy of the games is being transmitted and saved to millions of DVRs or other forms of data storage servers around the world.

For the time being, I prefer that my DVR support more usable storage capacity and real-time compression so that I can keep more copies of my favorite shows and of course the Olympics all in HDTV, which of course chews up storage space faster than a highly animated PowerPoint slide deck from your favorite vendors most recent, or, upcoming product announcements.

The other theme is in addition to being Olympic time, as well as late summer here in the northern hemisphere or winter for our friends in the summer hemisphere, its also pre-briefing and early product announcement time for the barrage of fall server, storage, networking, I/O, software, virtualization and green related solutions. So far, Im not sure if its the Olympics or what, however the bait line on the upcoming announcements and briefings include the tags “Industry First”, “Industry Unique”, “Only Vendor”, “Only Product”, “Revolutionary”, “First Vendor” or “First Product”, “Fastest”, “Largest”, “Greenest” among other interesting spins and twists that would even make an Olympic gymnast dizzy.

So enjoy the Olympic , keep those hard disk drives in your DVR cool while managing the usable capacity and watch for more gold medal attempts both from Beijing, as well as from your favorite IT vendors coming to a podium to you soon with their upcoming announcements, some of which may be award winning. Also check out www.greendatastorage.com which is now also pointed to by www.thegreenandvirtualdatacenter.com that has a new look and feel as well as some updated content with more on the way.

StorageIO Spring Keynote and Speaking tour V2.008

Several new keynote and speaking engagements involving myself have been added to the StorageIO events page including among others:

April 8th, 2008 – SNW Orlando FL
Beyond Green-Wash:
IT Data Center Power, Cooling, Floor Space and Environmental (PCFE) Topics and Trends V2.008
This talk will move past what are the issues and reasons for going green and get right to the point of what you can do today leveraging various technologies, techniques and best practices to address PCFE and green environmental issues including EHS, low power and economic sustainment in an environmental friendly manner as well as what to include in a long term green strategy for your data center.

Chicago, May 13th-15th – StorageDecisions
Clustered Storage:
From SMB, to Scientific, to Social Networking and Web 2.0
The growth of structured and unstructured data continues at an explosive rate in most environments resulting in a constantly expanding data footprint requiring data and storage management resources. Similarly, the relative ease of use of NFS and Windows CIFS file sharing based storage, also known as Network Attached Storage (NAS), has led to a proliferation of NAS and Windows file servers which are not all that different from how the ease of use of personal computers (PCs) resulted in desktop and server sprawl. With the focus of many IT organizations today to do more with less, or, do more with what you have, clustered storage and clustered file serving have become a popular option to support modular, scalable and flexible growth. Clustered storage including clustered file serving, grid and web 2.0 based storage solutions are no longer confined to the specific high performance scientific applications they are commonly associated. Clustered storage serving is commonly being deployed to support a wide diversity of applications including commercial, entertainment or media, Web 2.0 and social networking along with grid, cloud and traditional scientific needs.

This session takes a look at among other topics:
? Look at what different clustered storage vendors are claiming and how their solutions differ
? Fact vs. Fiction, Myths and Realties of clustered storage
o Grid vs. Clusters, Cluster vs. Grid, what?s the differences
o Clustered storage is only for ultra large environments like Google
o Clustered file serving is only for high performance (HPC) environments
o SMBs and bulk storage applications can not benefit from clustered storage
? What are the caveats to be aware of when deploying clustered storage?
? What are some emerging trends and solutions to keep an eye on for clustered storage
? What are some questions that some vendors do not want you to ask about their solutions!

Green and Environmental Friendly Storage:
Practical Ways to Achieve Energy Efficiency
Green is in-and every storage vendor out there has a green story to tell. Despite the vendor and industry hyperbole about the environmental benefits of their products, there are still no standard metrics by which to measure and compare power consumption or energy efficiency claims. The challenge is sorting out and closing the gap between vendor green messaging and IT data center issues including power, cooling, floor space and other environmental topics including RoHS and e-waste disposal. This session looks at several practical techniques and technologies that you can leverage today to achieve an energy efficiency data center to sustain business growth in an economical and ecological friendly manner.

Topics that will be covered include among others:
? How truthful are vendor claims and what is ?Green wash?
? Facts and Fiction, Myths and Realities:
o Storage is cheaper to buy than to power
o Power avoidance vs. energy efficiency
o Are Solid State Devices (SSD) the silver bullet?
o Dedupe vs. Archive vs. Compression vs. Consolidation
? What?s real and achievable today, what are your options?
? Measuring and determining energy efficiency with emerging metrics
? How to do more with what you have and avoid forklift upgrades
? Who is the ?Greenest of them all? and where to learn more

I will also be keynoting at several TechTarget seminar series events around the U.S. including

Chargeback for storage

TechTarget SearchStorage recently put out a piece on chargeback for storage that includes some commentary by myself on the topic including some common myths about chargeback of what it is and how it is done.

A common misperception is that chargeback requires actual invoicing and monetizing of IT resource use including servers, storage and networks where in some cases, charge back is not as much about generating invoices as it is for accounting and resource usage tracking.

Granted, if you are in a services oriented environment, rest assured there is monetization needing to take place, however, informational charge back initiatives are also useful for budgeting, planning and awareness of IT services and usage.Have a read here.

Trains Going “Green”, ah, well, maybe “Blue”…

With all of the global focus on going green, saving the planet, green IT and green storage all of which are good when like so many other things when done in moderation, the focus especially around IT and even aviation tends to be around green house gas (GHG), Co2/Carbon Offsets and so forth. Well, when I read this article about what India is doing to make their trains more green it got me thinking, perhaps a more moderate or balanced approach to green messaging should include more looking down at the ground than up in the sky.

That is, focus on some additional issues including ewaste with rules such as RoHS, WEEE among others in addition to the focus on reducing carbon and GHGs. By spending some time looking down as opposed to just looking up so to speak, you can reduce the chances of stepping in something undesirable as well as seeing real issues including power, cooling, floor space, environmental (PCFE) related items that can be addressed as well as on a go forward basis.

Interested in green IT and storage along with associated PCFE topics? I will be presenting at SNW in Orlando in April as well as Storage Decisions in May in Chicago on those and other related topics, learn more at the StorageIO events page. If you will be at any of those venues, stop by and say hello.

Was today the proverbal day that he!! froze over?

Storage I/O trends

The upper Midwest, well, make that the Midwest in general was hit by high winds and a nasty cold front today, nothing all that unusual for January, especially in the Minneapolis area where the temperature yesterday was 40 to 45 with light rain and by about noon today about zero “F” without the wind chill. So in the face of old man winter and the cold, I had a chuckle today reading the announcement that an SPC (Storage Performance Council) SPC1 (IOPS) benchmark had finally been published for an EMC CLARiiON CX3-40.

Now for those of you who cover or track or cheerlead or dread EMC, you probably know there position on benchmarks, or at least of some of their bloggers and in particular, SPC and if not, read here for some perspective. My position has always been the best benchmark is your actual application in a real and applicable workload scenario, however also realizing that not everybody can simulate or test their applications, there is the need for points of reference comparison benchmarks such as SPC, Microsoft ESRP, TPC, SPEC among others.

Heres’ the caveat, take these benchmarks with a grain of salt; use them as a gauge along with other tools as they are an indicator of a particular workload. I am a fan of benchmarks that make sense, can be reproduced consistently and that are realistic representations, not a substitute for your actual applications. They are tools to help you make a better informed decision however that is all they are, a relative comparison.

Nuff rambling for now on that, why did I chuckle this morning and think that He!! had perhaps finally froze over, and don?t get me wrong, Minneapolis and the Midwest for that matter is far from being He!!!, granted its cold as crap during the winter months. The reason I chuckled is that EMC did not in fact submit the SPC1 benchmarks for the CLARiiON CX3-40, instead, one of their competitors namely Network Appliance (aka NetApp) did the honors for EMC along with a submission for their FAS3040.

So besides the fact that there is plenty of wiggle and debate room in the test for example NetApp using RAID6 (e.g. RAID-DP) and Mirroring on the EMC (I?m sure we will hear EMC cry foul), EMC can keep their hands clean on their party line about not submitting an SPC1 result, or at least that?s a card they could choose to play.I would like to see the DMX4 particularly with the new FLASH based SSDs in a future SPC test submission; however, I?m not going to hold my breath at least yet.

However it is ironic that EMC has in fact submitted other benchmark tests scenarios in the past including for Microsoft ESRP among others. Speaking of SPC submissions, TMS (Texas Memory Systems) also posted some new SPC results the other day.So maybe he!! did not really freeze over today with EMC finally submitting an SPC test, however it made for good warming chuckle on a cold morning.

Now, even though EMC has not officially submitted the SPC1 result, even though it is posted on the SPC website, that leaves only one major storage vendor yet to have their midrange open storage systems represented on the SPC results, and that would be HDS with their AMS series, maybe He!! will still freeze over…
