HDS Dynamic Provisioning for AMS

HDS announced support today for their thin provisioning (called Dynamic Provisioning) feature to be available in their mid-range storage subsystem family the AMS. Expanding the subsystems that support Thin provisioning can only help the customer in the long run.

It’s not clear whether you can add dynamic provisioning to an already in place AMS subsystem or if it’s only available on a fresh installation of an AMS subsystem. Also no pricing was announced for this feature. In the past, HDS charged double the price of a GB of storage when it was in a thinly provisioned pool.

As you may recall, thin provisioning is a little like a room with a bunch of inflatable castles inside. Each castle starts with it’s initial inflation amount. As demand dictates, each castle can independently inflate to whatever level is needed to support the current workload up to that castles limit and the overall limit imposed by the room the castles inhabit. In this analogy, the castles are LUN storage volumes, the room the castles are located in, is the physical storage pool for the thinly provisioned volumes, and the air inside the castles is the physical disk space consumed by the thinly provisioned volumes.

In contrast, hard provisioning is like building permanent castles (LUNS) in stone, any change to the size of a structure would require major renovation and/or possible destruction of the original castle (deletion of the LUN).

When HDS first came out with dynamic provisioning it was only available for USP-V internal storage, later they released the functionality for USP-V external storage. This announcement seems to complete the roll out to all their SAN storage subsystems.

HDS also announced today a new service called the Storage Reclamation Service that helps
1) Assess whether thin provisioning will work well in your environment
2) Provide tools and support to identify candidate LUNs for thin provisioning, and
3) Configure new thinly provisioned LUNs and migrate your data over to the thinly provisioned storage.

Other products that support SAN storage thin provisioning include 3PAR, Compellent, EMC DMX, IBM SVC, NetApp and PillarData.

EMC Better At Acquisitions?

I was talking with an EMCer the other day about the Data Domain deal and he said that EMC does very well with acquisitions. Just about every EMC product line other than Symmetrix (and possibly Celerra, Invista, PowerPath and maybe others) came from an acquisition in EMC’s past.

The list goes something like this Clariion from Data General, Centerra from FilePool, Control Center from BMC, Networker from Legato, RainFinity, Avamar, Documentum, RSA all from companies of the same name. There are other examples as well but these should suffice for now. One almost starts to forget about all these separate companies that existed prior to EMC’s acquisitions. Over time EMC manages to succeed in advancing and integrating the various technologies and products into their portfolio.

On the other extreme is Sun. They have almost a perfect record of acquiring companies and burying the technology away. Often the technology does emerge after a gestation period in another Sun product somewhere else but just as often it just fades away never to be seen again.

Today’s companies have to do acquisitions well. They can no longer afford the luxury to acquire companies and then see their investment die away. Those days are long gone

What makes EMC so successful while others can do so poorly? One thing I have learned is that EMC leaves a new acquisition pretty much alone for 12 months or so. During that time presumably they are assessing the current management team for EMC cultural fit and determining the best way to sell, advance and integrate the acquired technology into the rest of EMC’s product and services portfolio.

The other thing I have noticed is that EMC’s most recentr acquisitions have retained at least portions of their original brand names. Networker, RainFinity, Documentum, and RSA are examples here.

I don’t know what it is about retaining a brand name but 1) it makes it harder to let it fade away because it’s so visible, 2) employees who have a personal interest in the brand fight to keep it alive and advancing, and 3) customer base and loyalty is retained better.

Just pieces of the puzzle but no doubt there is more to this than is visible externally.

How well NetApp will do as an Acquirer is another question. I know they have acquired Spinnaker, Alacritus, Decru, Topio, and Onaro over the past five years. Most of these products are still being sold. Rumors point to Spinnaker technology being merged into NetApp’s mainline product soon. All in all, I would have to say that although NetApp has retained the product names for most of these products Onaro’s SANScreen, Decru’s DataFort and others, they haven’t necessarily done a good job keeping the brandnames alive.

What NetApp will do with Data Domain however, is another matter entirely. First, the price being paid is much higher than any previous acquisitions. Second, the market share that Data Domain currently enjoys is much larger than any previous acquisition. Finally, it’s crucial to NetApp’s future revenue growth to do this one right. Given all that, I truly believe they will do a much better job with retaining Data Domain’s brand and product names, thereby keeping the product alive and well for the foreseeable future.

Data Domain bidding war

It’s unclear to me what EMC would want with Data Domain (DD) other than to lockup deduplication technology across the enterprise. EMC has Avamar for Source dedupe, has DL for target dedupe, has Celerra Dedupe and the only one’s missing are V-Max, Symm & Clariion dedupe.

My guess is that EMC sees Data Domain’s market share as the primary target. It doesn’t take a lot of imagination to figure that once Data Domain is a part of EMC, EMC’s Disk Library (DL) offerings will move over to DD technology. Which probably leaves FalconStor/Quantum technology used in DL today as outsiders.

EMC’s $100M loan to Quantum last month probably was just insurance to keep a business partner afloat until something better came along or they could make it on their own. The DD deal would leave Quantum parntership supporting EMC with just Quantum’s tape offerings.

Quantum deduplication technology doesn’t have nearly the market share that DD has in the enterprise but they have won a number of OEM deals not the least of which is EMC and they were looking to expand. But if EMC buys DD, this OEM agreement will end soon.

I wonder if DD is worth $1.8B in cash what could Sepaton be worth. They seem to be the only pure play dedupe appliance left standing out there.

Not sure whether NetApp will up their bid but they always seem to enjoy competing with EMC. Also unclear how much of this bid is EMC wanting DD or EMC just wanting to hurt NetApp, either way DD stockholders win out in the end.

Data Domain and NetApp

Data Domain has been a longtime partner of NetApp’s, which is probably one reason that NetApp finally decided to make them an offer. Another reason why it’s right to do this now is that in today’s economy, NetApp could get the best price.

The final reason that NetApp and Data Domain should hook up is that there are not many other major storage vendors that don’t already have a dedicated deduplication appliance or two. If Sun were still around it might make sense for them to think about buying Data Domain but they are out of the picture until Oracle figures out what to do with their storage business. EMC has bought Avamar and invested significantly in Quantum. IBM has purchased Diligent, Symantec has PureDisk. HP already has a deduplication product. The only major vendor without dedupe today is HDS.

Data Domain had a lot going for them. They practically defined the target deduplication appliance market. Diligent (now with IBM), Quantum, Sepaton, and others notwithstanding, Data Domain had the largest market share out there and was continuing to experience rapid growth. The fact that Data Domain both supported NAS as well as VTL access modes coupled with their excellent market share made them a prime acquisition on many fronts.

NetApp, of course, has their own deduplication technology which has been very successful in supporting virtual server environments primary storage and was also used to support secondary storage. No doubt over time these two technologies could conceivably merge into one. But don’t hold your breath, some companies have way more than two distinct deduplication technologies which are used for their various products and NetApp may not feel its worthwhile to combine the two technologies in the near future given there two different markets.

All in all, consolidation is necessary evil today.
