3. Remote Office Problems are Converging
Remote Office users want high-performance access to corporate data, but corporate IT wants to cut costs and needs to control and protect critical data
Storage Problems
Site consolidation of servers and storage
Need to connect islands of storage
Remote site backup
Application Problems
Web, , FTP, Notes, ERP, Database, etc. applications experience slow response times, and so are not often used – too slow
Networking Problems
Need “More Bandwidth”
Latency kills throughput
To meet the performance demands on the edge, many companies have deployed resources—mostly servers, but some support; thus, there’s a lot of data scattered over a lot of remote offices.
But now that data has become very difficult to manage and protect—it’s very fractured.
Develops seemingly opposing goals:
Performance to central data for the remote sites.
Lower costs and more control over critical data.
Moreover, distributed infrastructures run into a variety of other pain points.
Storage Problems
Islands of storage make it very difficult to collaborate / share information.
Very difficult to protect scattered data—often the cleaning staff, admin assistant, or mechanic is tasked with swapping tapes. How reliable is that? And what about losing tapes in the mail?
Application problems
Applications are chatty, and with high latency, their performance suffers drastically.
One customer (Insurance company) reported that agents stopped signing up new customers because the web app took 20 minutes to respond.
Networking problems
“More bandwidth”: Many WAN performance issues are perceived to be bandwidth related (it’s latency!), so many customers are paying for expensive wider pipes that they don’t need.
Latency kills throughput: Typical cross-country latency is 100ms. 10 requests, even at infinite bandwidth take a full second—and it adds up fast!

Important: slide animation!
We stated on the previous slide that WAN performance issues can be fairly neatly divided into three categories: Network-related, storage-related, and Application related. There are thus many solutions from several competitors in each category:
Network Centric solutions:
Network Compression appliances
TCP Optimization appliances
Measurement & Monitoring
QoS
Storage Centric solutions
File caches aka Wide Area File Services (WAFS)
Application Centric solutions
Web caches
Content caches
Mail caches
But we know it’s not just a network problem; it’s not just a storage problem; it’s not just an application problem—it’s a remote office problem. That’s why competing solutions are beginning to converge.
HP has introduced a new category: Wide Area Data Services (WDS) that is a superset of the existing categories. Only HP’s technology addresses the majority of WAN performance issues, and isn’t focused on a narrow category.

6. Wide-area data services (WDS) is an integrated approach
Applications
LAN-like WAN performance
Networking
Overcome bandwidth and latency constraints
Our approach exceeds all three previous generation WAN optimization technologies, but in one device.
Riverbed Steelhead appliances:
Accomplish WAFS, and much more
Accomplish network compression and TCP optimization, and more
Accomplish application acceleration, and more!
An additional technology, discussed later, enables Steelhead appliances to operate even with a WAN failure. Even with this functionality turned off, Riverbed accomplishes the goals of ALL THREE of these older types of technology.

11. How does HP EFS WAN Accelerators Provide WDS?
Accelerate TCP traffic over WANs – CIFS, NFS, HTTP, FTP, MAPI
Enables site consolidation for servers & storage
Speeds up backup & replication over WANs
Increases capacity of low bandwidth WAN links
Increases utilization of high bandwidth WAN links
Completely transparent to clients and servers – preserves the client-server relationship
Use multiple technologies working together
Byte-level caching
Best-in-class compression / data reduction
Latency optimization
Predictive traffic analysis
Accelerate applications used on WANs by up to 100 times, excelling at CIFS and MAPI.
Enable site consolidation for servers and storage by creating LAN-like performance on the WAN. Reduces TCO by up to 40% and complexity of distributed IT infrastructure; more control over data and easier regulatory compliance.
Speed up backup and replication over WANs – eliminates the need for local remote office backup and the headaches it creates.
By increasing the capacity of low bandwidth WAN links – puts off expensive WAN upgrades or enables cost-effective WAN downgrade.
Unlike file cache solutions, the HP EFS WAN Accelerator preserves the client-server relationship, rather than spoofing the server.
No changes to current IT infrastructure, clients or servers - up and running quickly with little or no interruption to the network
Byte-level caching is not a file cache! But it provides the same benefit.
This is not simply a compression appliance! But it performs compression and data reduction techniques.
WAN performance issues are often not for lack of bandwidth - it’s the latency! Chatty protocols (requiring many round-trips) suffer from high WAN latency.
The appliance can predict what request is coming next (an open is followed by a read, for instance), thus keeping those client-server requests off the WAN.
Why we replace caching:
Like a cache, we store data locally, which improves the performance for data sent across the WAN
Unlike a cache, we handle all TCP traffic, not just one type (like files, web or mail for example)
Unlike a cache, which is a proxy server, WAN Accelerator appliances are not proxy servers
We send every client request to the origin server in real time
We never “serve” anything from the edge; our box just decodes requests and reassembles requests that were served by the origin server
Best-in-class compression
WAN Accelerator appliances far outperform (by a factor of 5-10x) the next best compression appliances on the market. While other WAN compression appliances offer up to 10:1 compression (Peribit claims up to 7.2x compression in their latest white paper (see ). Riverbed can achieve compression ratios as high as 400:1 in single transactions.
Our technology is sometimes described as being more like data “suppression” rather than “compression”
Our objective is to never send data across the WAN that has ever been across before
We don’t compress existing TCP payloads; rather, we examine payloads and determine whether we even have to send data at all
We address the impact of application level protocol latency (compression appliances do not)
Even new disk-based products announced by some customers do not have application-level protocol optimizations (which we refer to as “Transaction Prediction”), so they will have little to no impact on Windows or Exchange performance over the WAN
Adding a disk to a compression appliance does not solve all the problems. There are two dimensions to consider
How far back in time can you look for repeated patterns (how much data do you store)
When repeated data is found, how much of it can be represented by a “code” (or a “reference” in our case)
We believe that our algorithms outperform our compression competitors on pure WAN optimization. They can introduce a product with an equivalent amount of disk, but that alone will not deliver the performance.

Text on slide pretty self-explanatory--more notes below.
What are the features, functions, benefits?
EFS WAN Accelerators are based on HP ProLiant server hardware, ensuring seamless integration into established ProLiant environments. The complexity of distributed IT infrastructures and costs are reduced when file and application servers are centralized from remote offices to data centers.
EFS WAN Accelerators can be easily integrated into any enterprise network (either in-path or out-of-path), and are typically installed in less than ten minutes. These installations in remote offices provide a means to eliminate backup headaches there by enabling remote data to be copied across the WAN to a server in the data center, and then go to tape there.
EFS WAN Accelerators can remove repetitive traffic from the WAN; they will typically remove 60% to 95% of traffic allowing increased bandwidth of up to twenty-fold in an existing WAN. These appliances deliver high performance and near-real-time access to centralized storage – with faster files transfers and no bottlenecks, allowing consolidating servers and remote office backup to the datacenter. With the HP Enterprise File Services WAN Accelerator Manager, a fleet of up to 500 distributed EFS WAN Accelerator appliances can be centrally managed.
Ensures seamless integration into established ProLiant environments, including support for HP Systems Insight Manager and Integrated Lights-out (iLO) features.
In the event of hardware, software, or power failure, EFS WAN Accelerators have a dual port NIC that fails through to wire. In that event, clients still have access to remote servers, albeit at the original slow performance.
In new remote offices, instead of deploying local file servers, a local server, and local tape backup, you can deploy an EFS WAN Accelerator, and minimize the remote office infrastructure that needs to be deployed, maintained, upgraded, and patched.

13. HP WAN Accelerator Models

14. HP StorageWorks (EFS) WAN Accelerators LAN-like application performance over the WAN
HP StorageWorks Enterprise File Services (EFS) WAN Accelerators help customers put information to work by removing repetitive traffic and dramatically reducing latency effects on wide-area networks (WANs), delivering LAN-like performance for file, , web, and other TCP-based applications and protocols. Unlike WAN optimization products that focus solely on improving WAN bandwidth or on locally caching protocol-specific traffic, EFS WAN Accelerators deliver not only the industry’s highest bandwidth optimization for all TCP traffic, but work also address the effects of high latency on TCP and the applications that run on TCP. The IT appliances enable consolidation of distributed IT infrastructure from remote sites, resulting in savings by reducing equipment, IT staff needed, and the complexity of a global network.
RSM is the only replication management interface that integrates both remote and local replication. It also provides an interactive topology manager to graph the replication environment and allow actions on those objects. The comparative EMC GUI for CX called Replication Manager only provides local replication management and does not deliver graphical views of the replication environment; does not offer customizable views and does not provide integrated wizards to fully complete end-to-end replication tasks.
RSM’s “one click, no manual” approach makes it the fastest and easiest replication management available! As an example, to create a basic snapshot of a volume HP does this in one simple step with just 5 clicks of the mouse. Comparatively, EMC requires 5 discrete, non-integrated steps and 35 mouse clicks to do the same. That is an 85% reduction in user workload compared to EMC along with a significant reduction of risk in input errors.
Best of all, HP includes this capability as part of both Business Copy and Continuous Access at no additional charge. EMC (and others) charge for their advanced management GUIs with EMC topping the charts at $50,000
RSM along with Business Copy and Continuous Access brings even more value compared to EMC
HP provides free - Integrated and Remote local management – EMC Replication Manager for the CX is local only
True space efficient snapshots – HP provides instantaneous Vsnap where space is dynamically allocated as needed; EMC requires the user to create a dedicated “save area” that can only be used for snapshots and other replication needs. This is wasted space and if the user does not plan properly, the snapshots can become invalid if the save area space becomes full
HP can change Vsnap and Snapclone RAID types and even place Snapclones on different disk groups that contain FATA drives for better storage utilization. Ask EMC if they can do this- the answer will be NO
HP provides instantly available Snapclones– EMC requires prior synchronization making planned point-in-time replicas more difficult.

16. Customer Impact of WAN Accelerators
Customer Problem
Business/IT
What they do today?
How EFS WAN Accelerators solve the problem & add business value
Why now with HP?
Differentiators…
Remote location IT consolidation
Put off consolidation to continue to provide high performance access to remote users
Consolidate to the datacenter, only to leave remote users with painfully slow application performance over the WAN
Address performance issues affecting WANs by removing repetitive traffic and dramatically reducing latency, delivering LAN-like performance file, , web, and other TCP-based applications.
Enable customers to consolidate file and application servers from remote offices to the datacenter while preserving high-performance access for remote users
EFS WAN Accelerators reduce WAN traffic for all applications running on TCP and combine three types of WAN optimization into one product while other products available in the marketplace typically address only one or two types of optimization or only one type of traffic
Remote office backup
Depend on untrained personnel to manage remote office backup and tape rotations
Lose tapes (and important customer data!) in transit between sites
IT consolidation: file servers
High-performance, two-way access to storage over the WAN means faster file transfers and no bottlenecks--remote data can be quickly copied across the WAN to the datacenter, and then go to tape there.
Transparent support for backup software like HP Data Protector natively.
Preservation of client-server relationship mean no worries about remote/local data coherency
Inefficient WAN link usage
Pay for expensive WAN bandwidth upgrades because of user complaints
Utilize only a fraction of available bandwidth on fat (>100Mbps) connections
Eliminate the need for costly WAN upgrades by removing repetitive traffic from the WAN thereby increasing capacity of low bandwidth links.
Affect TCP flow control to increase utilization of high bandwidth/high latency links
Combine technologies to address bandwidth and throughput shortcomings for both low-bandwidth and high-bandwidth/high-latency WAN links.
Not meeting Backup Window
What they do today
Gamble – run risk of losing data
Impact production environment – accept lower performance until backup jobs have completed
In many companies, nightly backup reports are delivered up the IT management infrastructure. Excessive backup failures (either on success rate or SLA basis) have visibility
How the VLS6000 solves the problem
Accelerates backup performance by allowing more jobs to happen at the same time so the backup window is achieved
Improves process reliability (removes tape handling, bad media, and physical drive related errors)
Removes infringement of the backup jobs on the production resource
Reduces failures and SLA violations resulting in fewer reportable incidences
Slow Restores
Devote storage administrator resources for this task at the expense of other activities (e.g. development)
Accept lower productivity of department that is waiting on resources – LOST $$$
Reduces the restore time thus off-loading storage administrators and help desk operators  more time to do application development!!!
Allows quicker time to productivity by resources that were affected by data loss  more productive workforce!!
Inefficient media usage
Purchasing more media
Over-paying for offsite services – since more media than is necessary goes offsite, the subscription/retrieval costs are higher than necessary
Reduces the number of tape copies required
Many customers are cloning tapes – one for onsite, one for offsite. This eliminates the onsite media expense (onsite media expense is recurring due to media wear-out)
More efficiently fills media resulting in fewer pieces needed
Some customers are not fully filling media for various reasons
Complexities with multiplexing streams from the LAN
Short backups such as Database re-do logs
Copy jobs de-multiplex the virtual media to physical media and put data back to back resulting in better usage
Perishable data is never sent to tape media (database redo logs are only good until the next backup).
Position EFS WAN Accelerators as a way to virtually extend the datacenter LAN to remote sites
