ExEcutIVE SuMMAry

Te storage industry is undergoing a transition. Inrastructure and operations (I&O) execs know that

storage is a core component o enabling private cloud environments. But to achieve cloud exibility and

economics, the storage architectures in place needed to change. With many acquisitions taking place, as

well as new solutions on the market, I&O proessionals must prepare their storage environments. Tis

document will walk you through the drivers shaping the midrange storage market, the 10 criteria that

I&O teams should ocus on when selecting a solution, and a summary o the top 11 solutions in the space.

New BuSINeSS INITIATIVeS FORCe New STORAge SOLuTIONS

Most organizations today have SAN deployments in their environments. However, in the past year or

so, weve seen I&O teams start data center consolidation and look to deploy a private cloud (see Figure

1).1 Te goal is to leverage their technology platorms as part o their competitive advantage. Tis has

generated a number o dierent initiatives in I environments, including: 1) converged inrastructures,

which couple server, storage, and network together, and 2) re-evaluating the storage equipment, either

because it has reached end o lie or because I organizations are suering rom capacity growth and

task overload. Private cloud requires a level o automation and eciency that traditional storage

solutions havent delivered in the past. As a result, I&O teams ace three primary challenges:

Te business has no idea what its data is. Much o the data stored today hasnt been touchedin some time and is sitting idle. Its important to assess data and rationalize which data truly

requires primary capacity.

I&O and broader I silos still exist. Silos cant continue i your organizations initiativessuch as private cloud are going to succeed. Yet most storage purchasing decisions are made

separately rom other technology purchases, and the storage teams dont always communicate

with enterprise architecture, application development, or even other I&O teams like server and

networking.

Te wrong solution can hinder a bigger initiative. Oen, I&O teams dont communicate withlines o business and thereore dont know what kind o solution is needed or the initiatives at

hand.

Tese challenges and new business initiatives require much more than just hardware. Tey requirea simplifed and exible way o deploying storage in order to maximize resource eciencies.

Although most environments are Fibre Channel today, recent Forrester survey data shows that

organizations are actually moving orward with adopting various protocols. raditionally this has

required two dierent solutions, but I&O execs are now approaching unifed architectures that

simpliy the way o deploying and managing storage (see Figure 2).

A MIx OF 10 CRITeRIA ShApe The MIDRANge STORAge LANDSCApe

Although the market is evolving quickly, and the line between midrange and high-end storage

continues to blur, we have established 10 criteria to categorize a solution as midrange (see Figure 3).

Fir 3 How Midage Soage Soves Kow Poems


Emerging criteria

Criteria Business problem solved

Thin provisioning Helps avoid capacity being underutilized,therefore buying capacity when trulynecessary

Asynchronous and synchronousreplication

Both allow for data to be replicated moreeciently depending on the requirements

Multiprotocol support Allows for exibility and tiering; not tied toFibre Channel environment

Primary deduplication Eliminates duplicates, saving capacity

Automated tiering Tiering maximizes resources, allowing forhigh-end disks to be used for highperformance.

VAAI integration Tie between server/storage to determinesthe capacity needed for workloads; higherpeformance on servers

Storage virtualization Accessing data regardless of physicallocation/structure, managing storageeasier for dierent requirements

Stretch clustering Cluster nodes geographically dispersedacross distance, providing redundancy

Established criteria

Multihypervisor support allows fororganizations to leverage dierenthypervisors for dierent workloads,

depending on the business need.Object storage support Allows for metadata to be applied for

extracting more easily

Multihypervisor support

Fiv establisd Critria Driv Midran Stora Dcisions . . .

Tere are a number o proven storage technologies that have been on the market or some time now.

Although these eatures are not massively adopted just yet, they do oer the unctionality needed or

a successul private cloud deployment. I&O teams should prioritize these fve capabilities:

Tin provisioning. Tin provisioning is designed to optimize storage capacity in a sharedstorage environment. It allocates capacity on-demand as opposed to pre-allocating, thereore

increasing use. Capacity is normally oversubscribed, but it is only dedicated when data is


6/14




5

actually written on the application. Although thin provisioning has been on the market or

some time, I&O teams have yet to widely adopt it.

Asynchronous and synchronous replication. Most environments require synchronousreplication. But I&O should select solutions that have both capabilities and can identiy which

data needs which type o replication to drive more perormance eciency.

Multiprotocol support. Most SAN environments sit on Fibre Channel; however, we see anincrease in interest or other protocols such as NFS and iSCSI. Solutions with support or all

protocols are much more exible or eciency purposes and allow or eective tiering.

Primary deduplication. Tis is a process that looks or any redundant data. I it fnds aduplicate, the storage system will point to the original copy and eliminate the redundant data,

reeing up capacity. Although widely used in backup, its much more benefcial in a primary

storage environment, as it will signifcantly reduce the amount o capacity used.

Automated tiering. iering is a key unction to enabling a private cloud and has been a manualand tedious procedure or a long time. Automated tiering places hot data on high-perorming disk

and warm data, which isnt accessed as much, on cheaper disk, balancing out the cost eciencies.

. . . Bt Fiv emrin Critria Ar Ncssary To Sort N, Dynamic workloads

oday, the server, network, and storage environments are becoming more integrated than ever.2

Te impact o initiatives such as server virtualization and VDI undamentally change the way

storage and network resources are dynamically allocated. Most organizations suer today because

o lack o preparation in designing their server/desktop virtualization environments. As a result,storage growth has spiraled out o control, and perormance or deployments on both the network

and storage side have suered. As these initiatives continue to roll out, the server, network, and

storage environments must understand the impact on each other and work in sync to deliver the

necessary resources or exible and intensive workloads. Te solution is not to continue adding

more hardware but to begin to understand the dierent eatures and unctionalities that can help to

address some o these concerns. We recommend that I&O teams ocus on fve emerging capabilities:

Storage virtualization. Similarly to server virtualization, storage virtualization eliminates thedependencies between data and where its stored. Tis allows or exibility in how capacity is

managed.

Stretch clustering. Stretch clustering is critical when one or more cluster nodes o a SAN aregeographically remote. Dierent rom vMotion, this is a group o ESX/ESXi instances within

vCenter where at least some o the hosts in the cluster live in separate locations. vMotion, on the

other hand, is the live migration o a guest virtual machine rom one host to another.


7/14




6

Multihypervisor support. Despite VMwares dominance in hypervisors, storage admins mustplan or growth in alternatives. As the hypervisor and storage become more interdependent

on each other, storage systems must be able to support all hypervisors or environments where

there are more than one in production.

Object storage support. Objects allow or a more granular way o identiying data. Tey usericher metadata to easily retract data when needed based on soware capabilities with languages

such as RES or Java.

VAAI integration. For VMware-based environments, vStorage APIs or Array Integration(VAAI) is an API that allows VMware hypervisors to hand o storage unctions to storage

arrays, alleviating workload strain on the servers.

The MIDRANge STORAge LANDSCApe CONSISTS OF TwO VeNDOR CATegORIeS

Te storage vendor landscape has evolved, mainly due to consolidation. I&O teams are ocusing on

data center consolidation in the short term and enabling a private cloud long term.3 Tis is driving

vendors to oer a new set o capabilities as highlighted above. But it also led to the massive M&A

action we saw in 2010, where billion-dollar deals were struck.4 Although this report ocuses on

midrange solutions, in reality, the lines are blurring between high-end and the midrange space. Te

level o perormance and amount o capacity or midrange solutions have increased in recent years.

Tey are spilling over into the higher end range in terms o unctions and eatures. o navigate this

market, I&O teams should ocus on two basic categories o midrange storage vendors (see Figure 4).

Catory 1: Systms Vndors Tat Can Or Srvr, Stora, And Ntorkin

We examined six solutions rom fve vendors in this space. Tey are:

Compellent Storage Center 5.4. Compellent represents one o the core values o storage inprivate cloud models. Automated tiering creates resource eciencies that allow or a system

to identiy hot and cold data and place it on the most cost-ecient disks. Dells enhanced

capabilities place it in the top with its competitors. But Dell still needs to round out Compellent

with sel-service unctionality, orchestration, and more robust resource management

unctionality, to meet all I&O cloud needs. As most vendors look to do this, we expect Dell to

evolve Compellents capabilities to meet these requirements.

Dell EqualLogic PS6000XVS. Te technology o the ormer EqualLogic has always beencompetitive in this segment. oday, EQL Firmware 5.1 supports iSCSI and NFS protocols,

which are relatively less expensive than Fibre Channel, reducing the cost o storage capacity. Its

support o NFS is benefcial to the server virtualization environment, as NFS is a much more

ecient protocol to leverage or this. Although it doesnt support Fibre Channel natively, it does

support Fibre Channel-like unctionality over DCB Ethernet, or organizations that are willing

to go down this route. Since most organizations primarily leverage Fibre Channel or their

entire environment, much consideration needs to be made in choosing a solution that natively

supports Fibre Channel.

Hitachi Data Systems (HDS) AMS. Although better known in the high-end storage arena,HDS oers a midrange solution, which oers the basic unctionalities such as thin provisioning,

snapshots, and cloning, but is oen overshadowed by its competitors EMC and NetApp. It

provides support or FC, iSCSI, CIFS, and NFS. However, HDS still alls short with automated

tiering and management capabilities as they relate to virtualized environments.

HP 3PAR. HPs acquisition o 3PAR was strategic to its position as a vendor that could ulfll theI/O requirements needed or virtualization and private cloud environments. Automated tiering,

a core criteria or the eciency o a private cloud, is 3PARs strength. i has been a leader in this

space, and HPs addition has made it a midrange solution that can enable I/O requirements oreciency. HP will need to urther integrate 3PAR into its overall portolio and help customers

into the transition rom its traditional HP EVA solution to a more robust solution that will help

customers in the private cloud journey.

IBM V7000. Te midrange market has evolved to include a number o the larger vendors,which have traditionally been in the high-end storage space. IBMs acquisition o V7000 delivers

midrange capabilities and meets all the established criteria with the exception o primary

deduplication. However, it lacks in the multiprotocol support area, a key requirement or

enabling private cloud environments.

Oracle Sun Storage 6000. With its acquisition o Sun, Oracles 6000 became its midrange solution.oday, the 6000 supports both synchronous and asynchronous replication. However, it doesnt

provide any thin provisioning, primary deduplication, or multiprotocol support all criteria that

should be a part o a midrange solution designed to enable simplifcation and eciencies.


10/14

Catory 2: Stora pr plays Or T Bst Ovrall economics

Te storage pure play market is dwindling because o all the industry consolidation, but its still the

sweet spot or I&O teams looking to meet aggressive storage needs with midrange solutions. Te top

players include:

EMC VNX. EMC has long been a ollower to NetApp in the midrange market. However,its recent release o VNX comes one step closer. It brings a great deal o the eatures and

unctionality that enable private clouds, including thin provisioning, primary deduplication,

automated tiering, and VAAI integration. Although EMC considers VNX a unifed solution,

it in act still runs separate operating systems DAR and FLARE in one device. Te

Unisphere management console eases the complexity and does alleviate a great deal o the

manual tasks, but the act is that its still two dierent environments.

Fujitsu Eternus DX440. Te company has maintained a storage solution within its portolioor some time but hasnt made much traction in the midrange space. Te solution oers all thebasic unctionality considered in our criteria, with the exception o primary deduplication. We

expect Fujitsu to ramp up on its storage solutions as it sets out to provide a cohesive server and

storage solution.

NetApp FAS3270. NetApp provides the leading unifed solution. It continues to expand itsportolio and grow within the market. Multiprotocol support and ease o use remain the most

valued capabilities by I&O and storage teams. However, primary deduplication continues to

gain adoption and will do so increasingly, as its a key eature or eciency within private clouds;

NetApp leads in making this unctionality work without signifcantly aecting perormance.

Te acquisition and integration o Akorri was a good step to urther extend NetApp capabilities,but more needs to be done in this area or building private clouds.

Pillar Data. A company partially owned by Oracle, Pillar Data has been a staple in themidrange solution space. Its solution oers the required criteria, but the value o its solution

lies in its automated tiering capabilities. Its tiering allows you to set policies around your data,

instead o just basing the requirement on use alone. Being partially owned by Oracle challenged

the company in the area o innovation, as it competed to some extent against Oracles own

storage solutions.5

Xiotech ISE. Te ISE storage solution represents a new architecture or enabling the eciencieso cloud. It oers a hybrid storage environment that allows or automated tiering rom SAAto SSD, and its management capabilities help determine where data can reside most eciently

and eectively. Its sel-healing capabilities also allow or drives to be repaired within a datapac

without the need or taking everything out o service. However, Xiotech has suered rom

management changes and the perils that come along with changing strategy. Xiotech will need

to ocus on delivering the capabilities needed or a private cloud environment and ensuring that

it can integrate into other core areas to this environment, such as server and networking.

OTheR VeNDORS TO CONSIDeR

Forrester believes that the tie between server, storage, and network will continue to occur. Tere are

a number o innovative start-up vendors that are pushing the envelope to change the way storage is

built out and managed today, bringing together the server and storage worlds. Tey ocus on areas

that have changed the storage requirements and contribute intelligence to the virtualized or cloud

environment. Tese include vendors such as Virsto, whose virtualization management soware sits

within the hypervisor, bringing a better understanding o the virtual server environment; Nutanix,

which brings server and storage closer together; and SolidFire, which is oering SSD with Flash,

driving down the cost o SSD, while still providing a high level o perormance. Tey are all oering

a new way o creating eciencies within virtualized and cloud environments.

1 Recent Forrester inquiries rom enterprise inrastructure and operations (I&O) proessionals show that

theres still signifcant conusion between inrastructure-as-a-service (IaaS) private clouds and server

virtualization environments. As a result, there are a lot o misperceptions about what it takes to get your

private cloud investments right and drive adoption by your developers. Te answers may surprise you; they

may even be the opposite o what youre thinking. For more inormation, see the May 25, 2011, Q&A: How

to Get Private Cloud Right report.

2 I pros have most o the basic ingredients to cook up their own cloud-like inrastructure or support

complex applications but theres no recipe, and many ingredients just dont combine well. Complicating

the story are the traditional inrastructure silos around servers, networks, and storage that must work

together in a new, truly integrated way. Vendors like Cisco Systems, Dell, EMC, HP, and IBM have had basic

converged inrastructure (CI) oerings or several years but many I&O teams hesitated to deploy them,

as they required higher levels o integration. For more inormation, see the May 17, 2011, Are Converged

Inrastructures Good For I? report.

3 Inrastructure and operations (I&O) teams are acing a dicult challenge in the data center: tossing out

the rules o networking architecture. Aer years o just throwing bandwidth at the problem, todays I&O

teams are fnding they need to build undamentally dierent networks that accommodate advances in

server virtualization and storage networking and pave the path to cloud computing. odays traditional

three-tiered architectures are giving way to atter, converged Ethernet abrics. Why? A abric-based

approach provides the necessary exibility, perormance, and reliability to support new shared resources,

soware, and data models. Te goal o data center convergence and virtualization is to remove redundancy

in SAN networks and ineciencies in the compute spectrum and oer them rom an inormation grid,

AKA the cloud. For more inormation, see the December 15, 2010, Te Data Center Network Evolution:Five Reasons Tis Isnt Your Dads Network report.

4 Acquisitions have long been a part o the storage vendor landscape. But 2010 and the frst part o 2011
