EMC Says Dedupe, Cloud and SSDs Will Dominate Storage
May 20, 2009
By   Drew  Robb

ORLANDO, Fla. — EMC (NYSE: EMC) stressed afew key themes at this week's EMC
World show, among them public and private cloudcomputing, data
deduplication,virtualization and solid state flash drives
The data storage giant
expanded its dedupe productofferings, held something of a love fest
with Cisco (NASDAQ: CSCO) and VMware (NYSE: VMW),and EMC CEO Joe Tucci
heldforth on a range of issues in a Q&A session with the media.
EMC's backup product portfolio is getting anumber of new deduplication
features and upgrades. The latest version of EMC Avamar,for example,
hashad its deduplication and recovery capabilities extended across
more platforms. It can now dosource-based deduplication on Microsoft
(NASDAQ: MSFT) SharePoint Server 2007 and IBM LotusDomino.
"Backup to disk is
much better than tape forrecovery, but it costs more," said Tucci.
"Technologies such as data deduplication andcompression, along with
largerdisk drives, are bridging that cost gap."
Source-based products deduplicate data whereit resides, at the client or virtual machine(the source), rather than deduplicating itthrough a device (known as targett-based deduplication). Target-based tools areeither inline or post-processing (delayed).
"Source-based
deduplication is effectivewhen you are seeking to maximize compression
ratios or you need to deduplicate before youtransport data over the
network,"said Mark Sorensen, senior vice president of the Enterprise
Storage Division (ESD)in EMC's Storage Software Group. "Source is more
CPU intensive, but you getbetter dedupe efficiency."
He said source-based tools are ideal forVMware, remote offices and NAS, while a target is more appropriate for SAN-based
backup, where performance is more important thanthe deduplication
ratio.He gives the example of a database, where you don't usually get
as good a dedupe ratio.Anything where bandwidth constraint is a
concern, he said, is better for source-baseddedupe.
EMC Disk Library — the
company's target-based dedupeoffering — is another product that has
received a "wax and shine" this year.Better management and monitoring
have been added through integration with EMC DataProtection Advisor.
Strongerperformance and replication, as well as enhanced deduplication
capabilities, have also beenthrown in. According to Sorensen, Disk
Library models 1500 and 3000 have had theirreplication throughput pace
increasedby as much as 80 percent. The product line now comes with EMC
Networker path-to-tape andreplication support, Open
StorageAPI support
forSymantec (NASDAQ: SYMC) Veritas NetBackup, and API support for
Oracle (NASDAQ: ORCL) RecoveryManager, which optimizes the
deduplicationprocess on Oracle.
Sorensen believes that
target-based deduplication isalso a good idea for primary storage —Tier one in an EMC Celerra, for example,could be deduplicated to free
up space in that tier to maximize itseffectiveness.
EMC Networker, too, is
included in this round ofbackup upgrades. It now has source-based
deduplication, which is achieved by integrating itwith EMC Avamar.
Thisenables it to provide source-based deduplication for several
Microsoft products —SharePoint Server, SQL Server and Exchange Server— as well as Oracle databases.It continues to support VMware too.
Effectively, this adds data protection anddeduplication to traditional
backupenvironments.
"Most backups will beon disk by2012," predicted Sorensen. "Deduplication technology is
driving disk-based backup frompurely mission-critical data into the
backup mainstream."

Tucci Not Touchy

Tucci fielded severalthorny questions at a Q&A session with the media. He stressed that
R&D spending would stay thesame this year despite lower revenues. He’s also looking for what he terms"opportunistic acquisitions" to consolidate and strengthen thecompany's competitive position.
"Any possible acquisitions would be inand around virtualization, storage and security rather than enteringinto a new space," said Tucci.
What about the company being a target foracquisition by, say, Cisco or another tech giant? He brushed that one asidewithout any apparent discomfort, saying that few could afford EMC's market capof $25 billion.
"We are not for sale, and we see plentyof opportunities for growth," said Tucci. "Although we are obligatedto do what is in the best interests of shareholders, such an acquisition is notin our plans."
Another potentially contentious questionabout storage chief David Donatelli's defection to HP (NYSE: HPQ) was dealt with, again, withoutany change in demeanor or defensiveness.
"It happens that good people arepoached," he said. "Dave was a good leader, but the technologiststhat developed our key storage products are still alive and well."
He revealed the company’s long-term brandingstrategy, too. The name Documentum is no longer being used, and other brandssuch as Avamar and RSA Security are probably going to dwindle steadily in thecoming years.
"Apart from EMC and VMware, most brandswill be consolidated over time," said Tucci. "We don't want to be ahouse of brands."
While he is bullish about the concept of thevirtual data center, VMware, Symmetrix V-Max, deduplication, FCoE and several other technologies, for the second yearrunning he placed heavy emphasis on flash-based solid state drives (SSDs).
"Solid state drives will be the biggestchange in storage, a total game-changer, and flash will be the dominant type ofSSD for the foreseeable future," he said.” Within a year, it will beunusual to see a system like V-Max go out the door without SSD technologyinside."

Cisco, VMware Share EMC's Virtual Vision Forall the speculation about Cisco acquiring EMC, it was interesting to seeEMC,VMware and Cisco united in a panel on next-generation virtualizeddatacenters. The three have also been working together on Cisco's new Unified Computing System.
Ed Bugnion, CTO of the server access andvirtualization business unit at Cisco, Parag Patel, vice president of alliancesat VMware, and Chuck Hollis, vice president and CTO of global marketing at EMC,discussed the private cloud and what it will mean to the future of the datacenter.
"All three companies are working towardsa private cloud and the key technology behind this is virtualization,"said Hollis. "VMware provides the evolutionary path to the private cloud,which will be the dominant model."
One result of all theses that Cisco's Nexus1000V products, for instance, were designed with VMware in mind to take thisvirtual data center and virtual network concept a step further.
"The Nexus 1000V was designedspecifically for VMware and extends the network into the vSphere layer,"said Bugnion.
Patel termed VMware's
vSphere "an OS for theentire data center" that abstracts the infrastructure. In essence, ittakes the advantages of an internal datacenter and marries them with cloud computing to create a more dynamic and flexibleinfrastructure.
And big government could be the area thatreally pushes the cloud model into the mainstream. Hollis noted that thegovernment of Japanand the U.S.Department of Defense were already building their own privateclouds.
"Complex, process-driven environmentslike those big government are so inflexible that the cloud's flexibilitybecomes really appealing," said Bugnion."This will drive the creationof an internal federal cloud."
Attendance at this year's EMC World was downby about 2,000 to 7,000, but the role of social media was up, including some 2,000 tweetson Twitter.

A eloquent doubt, a certain that is conceivably most excellently answered prior to the start of trading is, 揾ow much do
you have a yen for to hazard on each trade?
