SNWUSA Spring 2013 summary

SNWUSA, SNIA, partyFor starters the parties were a bit more subdued this year although I heard Wayne’s suite was hopping to 4am last night (not that I would ever be there that late).

And a trend seen the past couple of years was even more evident this year, many large vendors and vendor spokespeople went missing. I heard that there were a lot more analyst presentations this SNW than prior ones although it was hard to quantify.  But it did seem that the analyst community was pulling double duty in presentations.

I would say that SNW still provides a good venue for storage marketing across all verticals. But these days many large vendors find success elsewhere, leaving SNW Expo mostly to smaller vendors and niche products.  Nonetheless, there were a\ a few big vendors (Dell, Oracle and HP) still in evidence. But EMC, HDS, IBM and NetApp were not   showing on the floor.

I would have to say the theme for this years SNW was hybrid storage. It seemed last fall the products that impressed me were either cloud storage gateways or all flash arrays but this year there weren’t as many of these at the show but hybrid storage certainly has arrived.

Best hybrid storage array of the show

It’s hard to pick just one hybrid storage vendor as my top pick, especially since there were at least 3 others talking to me under NDA, but from my perspective the Hybrid vendor of the show had to be Tegile (pronounced I think, as te’-jile). They seemed to have a fully functional system with snapshot, thin provisioning, deduplication and pretty good VMware support (only time I have heard a vendor talk about VASA “stun” support for thin provisioned volumes).

They made the statement that SSD in their system is used as a cache, not a tier. This use is similar to NetApp’s FlashCache and has proven to be a particularly well performing approach to use of hybrid storage. (For more information on that take a look at some of my NFS and recent SPC-1 benchmark review dispatches. How well this is integrated with their home grown dedupe logic is another question.

On the negative side, they seem to be lacking a true HA/dual controller version but could use two separate systems with synch (I think) replication between them to cover this ground?? They also claimed their dedupe had no performance penalty, a pretty bold claim that cries out for some serious lab validation and/or benchmarking to prove. They also offer an all flash version of their storage (but then how can it be used as a cache?).

The marketing team seemed pretty knowledgeable about the market space and they seem to be going after mid-range storage space.

The product supports file (NFS and CIFS/SMB), iSCSI and FC with GigE, 10GbE and 8Gbps FC. They quote “effective” capacities with dedupe enabled but it can be disabled on a volume basis.

Overall, I was impressed by their marketing and the product (what little I saw).

Best storage tool of the show

Moving onto other product categories, it was hard to see anything that caught my eye. Perhaps I have just been to too many storage conferences but I did get somewhat excited when I looked at SwiftTest.  Essentially they offer a application profiling, storage modeling, workload generating tool set.

The team seems to be branching out of their traditional vendor market focus and going after large service providers and F100 companies with large storage requirements.

Way back, when I was in Engineering, we were always looking for some information as to how customers actually used storage products. Well what SwiftTest has, is an appliance to instrument your application environment (through network taps/hardware port connections) to monitor your storage IO and create a statistical operational profile of your I/O environment. Then take that profile and play it against a storage configuration model to show how well it’s likely to perform.  And if that’s not enough the same appliance can be used to drive a simulated version of the operational profile back onto a storage system.

It offers NFS (v2,v3, v4) CIFS/SMB (SMB1, SMB2, SMB3) FC, iSCSI, and HTTP/REST (what no FCoe?). They mentioned an $8oK price tag for the base appliance (one protocol?) but grows up pretty fast, if you want all of them.  They also seem to have three levels of appliances (my guess more performance and more protocols come with the bigger boxes).

Not sure where they top out but simulating an operational profile can be quite complex especially when you have to be able to control data patterns to match deduplication potential in customer data, drive markov chains with probability representations of operational profiles, and actually execute IO operations. They said something about their ports have dedicated CPU cores to insure adequate performance or something similar but still it seems to little to hit high IO workloads.

Like I said, when I was in engineering were searching for this type of solution back in the late 90s and we would have probably bought it in a moment, if it was available., the domain/web site services provider was one of their customers that used the appliance to test storage configurations. They presented at SNW on some of their results but I missed their session (the case study is available on SwiftTests website).


In short, SNW had a diverse mixture of end user customers but lacked a full complement of vendors to show off to them.   The ratio of vendors to customers has definitely shifted to end-users the last couple of years and if anything has gotten more skewed to end-users, (which paradoxically should appeal to more storage vendors?!).

I talked with lots of end-users, from companies like FedEx, Northrop Grumman and AOL to name just a few big ones. But there were plenty of smaller ones as well.

The show lasted three days and had sessions scheduled all the way to the end. I was surprised at the length and the fact that it started on Tuesday rather than Monday as in years past.  Apparently, SNIA and Computerworld are still tweaking the formula.

It seemed to me there were more cancelled sessions than in years past but again this was hard to quantify.

Some of the customers I talked with thought SNW should go to a once a year and can’t understand why it’s still twice a year.  Many mentioned VMworld as having taken the place of SNW in being a showplace for storage vendors of all sizes and styles.  That and the vendor specific shows from EMC, IBM, Dell and others.

The fall show is moving to Long Beach, CA. Probably, a further experiment to find a formula that works.  Let’s hope they succeed.



New cloud storage and Hadoop managed service offering from Spring SNW

Last week I posted my thoughts on Spring SNW in Dallas, but there were two more items that keep coming back to me (aside from the tornados).  The first was a new startup called Symform in cloud storage and the other was an announcement from SunGard about their new Hadoop managed services offering.


Symform offers an interesting alternative on cloud storage that avoids the build up of large multi-site data centers and uses your desktop storage as a sort of crowd-sourced storage cloud, sort of bit-torrent cloud storage.

You may recall I discussed such a Peer-to-Peer cloud storage and computing services in a posting a couple of years ago.  It seems Symform has taken this task on, at least for storage.

A customer downloads (Windows or Mac) software which is installed and executes on your desktop.  The first thing you have to do after providing security credentials is to identify which directories will be moved to the cloud and the second is to tell whether you wish to contribute to Symform’s cloud storage and where this storage is located.  Symform maintains a cloud management data center which records all the metadata about your cloud resident data and everyone’s contributed storage space.

Symform cloud data is split up into 64MB blocks and encrypted (AES-256) using a randomly generated key (known only to Symform). Then this block is broken up into 64 fragments with 32 parity fragments (using erasure coding) added to the stream which is then written to 96 different locations.  With this arrangement, the system could potentially lose 31 fragments out of the 96 and still reconstitute your 64MB of data.  The metadata supporting all this activity sits in Symform’s data center.

Unclear to me what you have to provide as far as ongoing access to your contributed storage.  I would guess you would need to provide 7X24 access to this storage but the 32 parity fragments are there for possible network/power failures outside your control.

Cloud storage performance is an outcome of the many fragments that are disbursed throughout their storage cloud world. It’s similar to a bit torrent stream with all 96 locations participating in reconstituting your 64MB of data.  Of course, not all 96 locations have to be active just some > 64 fragment subset but it’s still cloud storage so data access latency is on the order of internet time (many seconds).  Nonetheless, once data transfer begins, throughput performance can be pretty high, which means your data should arrive shortly thereafter.

Pricing seemed comparable to other cloud storage services with a monthly base access fee and a storage amount fee over that.  But, you can receive significant discounts if you contribute storage and your first 200GB is free as long as you contribute 200GB of storage space to the Symform cloud.

Sungard’s new Apache Hadoop managed service

We are well aware of Sungard’s business continuity/disaster recovery (BC/DR) services, an IT mainstay for decades now. But sometime within the last decade or so Sungard has been expanding outside this space by moving into managed availability services.

Apparently this began when Sungard noticed the number of new web apps being deployed each year exceeded the number of client server apps. Then along came virtualization, which reduced the need for lots of server and storage hardware for BC/DR.

As evident of this trend, last year Sungard announced a new enterprise class computing cloud service.  But in last week’s announcement, Sungard has teamed up with EMC Greenplum to supply an enterprise ready Apache Hadoop managed service offering.

Recall, that EMC Greenplum is offering their own Apache Hadoop supported distribution, Greenplum HD.  Sungard is basing there service on this distribution. But there’s more.

In conjunction with Hadoop, Sungard adds Greenplum appliances.  With this configuration Sungard can load Hadoop processed and structured data into a Greenplum relational database for high performance data analytics.  Once there, any standard SQL analytics and queries can be used against to analyze the data.

With these services Sungard is attempting to provide a unified analytics service that spans all structured, semi-structured and unstructured data.


Probably more to Spring SNW but given my limited time on the exhibition floor and time in vendor discussions these and my previously published post are what I seem of most interest to me.

Super Talent releases a 4-SSD, RAIDDrive PCIe card

Not exactly sure what is happening, but PCIe cards are coming out containing multiple SSD drives.

For example, the recently announced Super Talent RAIDDrive UpStream card contains 4 SAS embedded SSDs that can push storage capacity up to almost a TB of MLC NAND.   They have an optional SLC version but there were no specs provided on this.

It looks like the card uses an LSI RAID controller and SANDforce NAND controller.  Unlike the other RAIDDrive cards that support RAID5, the UpStream can be configured with RAID 0, 1 or 1E (sort of RAID 1 only striped across even or odd drive counts) and currently supports capacities of 220GB, 460GB or 960GB total.

Just like the rest of the RAIDDrive product line, the UpStream card is PCIe x8 connected and requires host software (drivers) for Windows, NetWare, Solaris and other OSs but not for “most Linux distributions”.  Once the software is up, the RAIDDrive can be configured and then accessed just like any other “super fast” DAS device.

Super Talent’s data sheet states UpStream performance at are 1GB/sec Read and 900MB/Sec writes. However, I didn’t see any SNIA SSD performance test results so it’s unclear how well performance holds up over time and whether these performance levels can be independently verified.

It seems just year ago that I was reviewing Virident’s PCIe SSD along with a few others at Spring SNW.   At the time, I thought there were a lot of PCIe NAND cards being shown at the show.  Given Super Talent’s and the many other vendors sporting PCIe SSDs today, there’s probably going to be a lot more this time.

No pricing information was available.
