Oracle claims 640 KB granularitiy as "most efficient data granularity" - well, Netapp has 4 KB granularity for Snapshots, SSD- and Card-Caching, replication and so on. So NetApp is 160x more efficient than Oracle and 64.000x more efficient than the other competitors? Not that bad...
Oracle says "[Columnar] Compression is supported only on Oracle storage systems". This is the case only for some years now. It used to be supported before they bought SUN. Why? It is a software feature! It works with every 2.5" IDE/SATA/SAS/whatever Disk.
Disclosure: NetApp Empl.
is a Netapp. Chris, I'm disappointed that you're not aware of Netapp's most basic functionality. We do dedup in primary storage for more than 7 years now. And we can replicate all data and Snapshots deduped to a second and even third array. So absolutely no need for a dedup Appliance (and moving terabytes around for hours during backup) as everything is already deduped (and by the way: compressed too). And if you have a different primary storage and look for a dedup appliance for backup with heavy added value - go for syncsort with Netapp, it rocks :-)
NetApp does this on top of just stuffing virtual machines with storage:
- replicating data around on their gear, small to medium to large boxes and vice-versa > consolidation, intercontinental data protection - multiple topologies, old to new boxes and vv
- doing hundreds of snapshots on all data > uncomparable RPO, massive testing and development environments setup quick means excellent time to market, top sla's
- doing metrocluster transparent site failover in case of hardware component error > uptime increased
- having integration software for snapshots/clones for many major business apps > ease of use
- having some thousand engineers worldwide to provide worldwide 24/7 support for all class of business
- virtualizing other vendor storage to integrate it into new netapp feature ecosystem > investment protection
- delivering block and file storage from one system with the complete feature set below it (snaps, dedup, compression, worm)in all system families >> true unified storage, nobody else has it
btw, who were this tintri-guys?
Still the same old story
This product does this, that product does that. And we call it unified because you will get your 150 position invoice from one supplier.... EMC is creative in just one thing: creating new names for old stuff.
Dilbert Style CIOing
I have a vision....
CIO: we just bought that 3 million SAP Licenses and Consulting so storage must be cheap - could't get a discount with SAP
CIO: cheap! every disk is the same!
Admin: buys FATA Array, "cheap".
Years later, SAP performance hurts business much, new CIO in place. The former went on to new challenges - he is known for implementing SAP at low cost...
new CIO: my iPAD has flash memory - at least I read so - and it runs fast --- so why don't we buy flash for SAP?
Admin (still the same poor Guy): yes, but it is very expens...
CIO: buy it! I want iPad style performance in SAP!
Sounds smart. Because every Customer pre-orders new NAS Equipment without testing... Ah, I forgot, they assure....
EMC cant do Software
Even if they claim to be one of the largest sw manufacturers. I worked for emc for 7 years as a consultant and i saw navisphere, control center, symmetrix manager (which was already outsourced from cc very early cause the couldnt get cc to control their main storage, the same with navisphere) powerpath, geospan/srdf-ce and so on. They all sucked, were more then heavy to install and support was bloody bad even for internals. Its still the same. Emc cant do usable storage management software. The only stuff that was and is working are their command line tools - not very 2011.... Have a look at Dells storage or others shows you where to buy.
I.e. When upgrading CC in minor or major steps all historical data was lost! This was fact from 5.0 to 6.0 over several version and couldnt be fixed although there was an oracle db below...they needed to drop it. Customers liked this.....
Performance management is historical and ancient - for clariion and vmax. Collect data and get a zip file. Visualize the data in a sucking java gui that slows down even the fattest ram/cpu combo. Customers still complain about this.
I would never buy an emc system again, others just can do muuuch better.
Lets use real world Math
Assume that in the future these drives will mostly be used in tiered storage scenarios to provide suffcient io in front of a sata bunch (or marketing-speech "nearline-sas", sounds faster but isnt).
Then writes will go down on ssd but some algorithm will stage data to tier 2/3 from time to time. so the ssd will never fill up to its maximum. Lets say half the disk will be filled before the data is staged. You end up with 36.000+ ios per cell, right? Does it mean it will just last 2.5 years?
If my Name creation Guy would Name my newest hispeed Disk System After a MODEM from the stoneage I would Know what to do.... And If you ask the 25 year old hiflyer Sales guy about this He doesn't even Know about this....
Whatever, Renaming a product is often Done because of a Bad Reputation of the product....
grows by 150 ;-)
Hmm, maybe it leads to an invisible blackhole in the end. It is sucking up all data around and this is why we have so much growth in data out there...
