3. Business Continuity Some basic terminology
Recovery Time Objective (RTO)
How long after a failure can your business stand for an application to be offline?
Recovery Point Objective (RPO)
When the application comes back online, how current does the data need to be?
Cost
How much are you willing to spend on this insurance policy?
Unlike Infrastructure Simplification and ILM – which are generally choices – BC is often a required part of IT operations, demanded by stock holders, regulators and governments. It’s sort of like the insurance we take out on our auto, home, health and life. When we talk about BC, there are some key terms we all need to understand.
RTO
RPO
Cost 
It’s a game of probabilities. We would all like to have an RTO and RPO of zero – meaning no failure was ever noticed – but most of us aren’t willing to pay for those kind of BC solutions. So, we make trade offs. We balance the value of our information and probability of failure against the damage a failure would cause and determine what we are willing to spend. (click)

I’ll step through the kinds of technologies that can be deployed to provide these BC solutions – starting at the high end of the cost curve.
(click)
RTO and RPO’s that approach zero – Continuous Availability -- require a combination of geographically separated disk mirroring technologies – so that natural or man-made disasters can’t affect both the primary and recovery locations – combined with server clustering and automation software that integrate the storage, server and network failover – resulting in an integrated, automated site switch.
As we move down the curve toward Rapid Recovery, multi-site storage mirroring can be deployed without automated integration with server and network failover – manual intervention is required.
Metropolitan or inside-the-datacenter mirroring coupled with local clustering for protection against localized disasters
And simple mirroring without clustering integration
As we move away from Rapid Recovery to Backup / Restore we enter the realm of what has traditionally been thought of as tape backup. With newer low-cost disk technologies like S-ATA, this notion has been expanded to include disk-to-disk and disk-to-disk-to-tape backup with both manual and electronic offsite vaulting. (click)

At IBM, we think about the available BC solutions in three groupings. Generally, the lower the cost, the longer the RTO and RPO. As you approach RTO and RPO of zero, the cost of the solution escalates. (click)

6. Why Business Continuity? Protect your business
Remember that the average Fortune 500 company has something like 150TB of storage…
Why Business Continuity? Protect your business
Continuous Availability
I have to buy duplicate storage AND transfer across some network
The Problem
Rapid Recovery
I have to keep duplicate storage for all the FlashCopies
Backup/Restore
I have to daily transfer those TB’s across some network and store multiple copies on some media
Which data goes where and how do I get it there?
So, if BC is one of those things that most IT environments have no choice but to do, why are we talking about it? The reason is scale and cost. Storage is growing – rapidly. And BC solutions grow in cost with scale. (click)
If you choose Backup / Restore solutions, you have to provide a pile of tapes to copy all your growing data to. And generally two or three piles of tapes for the two or three copies you keep. On top of that you have to provide a network to send all that data over. (click)
If you choose Rapid Recovery solutions, you have to provide duplicate disk for all the copies. (click)
And if you choose Continuous Availability, you have to provide duplicate disks AND a network to replicate all that data across. (click)
And then there is the poor administrator who is left with the question. He would like everything to be Continuous Availability but he can’t afford that. What he can probably afford is Backup / Restore for everything – but that’s not good enough. The goal is to pick and choose some data to move up to higher levels – but how?
IBM has some unique technologies that can help you reduce the cost of providing each level of BC and help you get the right data into the right tier. (click)

One of the unique features of TSM is its Disaster Recovery Manager (DRM). One of the things we learned from recent natural and man-made disasters is that often times a disaster that impacts the computing infrastructure also impacts the people that operate that infrastructure. Recovery must be performed by people not necessarily familiar with the normal operations. This is where TSM DRM comes in
Depicted her as a gray circle, DRM encapsulates all the backup information required to recover along with an automatically generated DR plan and makes it available for manual or electronic vaulting.

IBM Tivoli Continuous Data Protection for Files, is a "data safety net" that provides real-time back up for important information such as Word documents, MP3 files, digital photos, presentations, and spreadsheets containing sales and tax records.
With people today more likely to be connected to a network through high-bandwidth wireless connections in coffee shops, parks and even entire cities, continuous backup of data is now practical. Previously, users have had to back up data through a scheduled backup session. With IBM’s new software, it happens continuously with one simple package that can be installed on laptops, desktop PCs or enterprise file servers.
“Nearly 90% of our employees are mobile, which means that we are constantly looking for ways to improve operational efficiencies, decrease costs and administration and protect important information stored on their systems,” said Winston Grey, IT manager, Consigli Construction in Milford, Mass. “With this new software, IBM is providing instant and automated backup of data and the added capability to restore deleted files with just a few clicks of the mouse.”
The software creates a copy on the local machine within milliseconds, and then sends another copy to a remote server. People on-the-go can protect and restore files that are corrupted or accidentally deleted, back to any point in time, even before they were lost – adding multiple layers of defense against data loss.
Imagine someone stuck in an airport, working wirelessly, who loses hours of work when a file freezes. Using the IBM software, that information is protected, even within the last few seconds of being entered. Additionally, while the user is working during the flight, the software continues to automatically save changes to documents locally. Once on the ground and back on the network, the software automatically sends those changes to the server for additional protection.
IBM Tivoli Continuous Data Protection for Files is easy to install in a matter of minutes. A CD takes users through a few simple steps, from determining where the data should be saved on the laptop, to configuring the remote server to receive the copy. Such fast, step-by-step installation makes it easy for people who lack advanced IT skills or do not have access to help desk support while on the road.
IBM studies show that loss of data, including time wasted while attempting to restore the information, is among the top problems for mobile workers. While larger companies often have system administrators who handle periodic data backup, that is often not a viable option for people working outside traditional office environments, such as sales people traveling between airports or telecommuters who work from home part-time.
IBM Tivoli Continuous Data Protection for Files can protect corporate data on enterprise servers, with the same fast and easy installation. The software simplifies heterogeneous storage management among enterprise servers and provides integrated data protection across all types of data formats. Working together with IBM Tivoli Storage Manager, the software provides complete file protection by automatically making copies of data locally, or across the network. Data can be guarded against deletion and alteration and protects against viruses and file corruption.
The software involves more than 10 patents pending on technologies for capturing continuous changes to data in tandem with remote scheduled back-up. A beta version of the software has been available to developers via IBM's alphaWorks site for emerging technologies. By providing developers with early access to emerging technologies, alphaWorks has become a breeding ground for IBM products and initiatives that have turned into market-leading solutions.
“With this new technology, IBM is providing customers and their mobile workers with an instant backup and recovery solution to protect information on demand," said Al Zollar, General Manager, IBM Tivoli Software. "We are extending our technology in storage management software to help people access all the information they need, when and where they need it."
IBM Tivoli Continuous Data Protection for Files is part of IBM's storage management software portfolio, including IBM Tivoli Storage Manager, which has been on the market for more than 10 years and was among the first backup and recovery software solutions in the industry.
IBM Tivoli Continuous Data Protection for Files will be available on September 16, 2005, at $35 per laptop or desktop, and $995 per server processor. The software will be sold direct through IBM and IBM business partners. For additional information on this product, please visit

11. Business Continuity Rapid Recovery
Now I want to talk about Rapid Recovery…
As I mentioed earlier, the technologies that you deploy to deliver Rapid Recovery solutions generally include disk mirroring.… (click)

12. Reduced Cost and Improved Flexibility for Replication Services
Traditional Storage Hardware
Replication targets must be the same enterprise-class disk as the source
Cost of deployment can be prohibitive for many clients
Lower-cost disks offer primitive, or no replication services
DS4000
Common replication API
Replication targets can be on lower-cost DS4000 disks, reducing the overall cost of exploiting replication services
Traditional disk mirroring technologies were built inside the storage controller – and required the same type of expensive storage for the copy target that was being used for the copy source. Further, mirroring technologies were not interoperable between vendors. This level of cost and complexity prevented IT managers from using mirroring technologies more pervasively. (click)
As we talked about during the Infrastructure Simplification session, physical consolidation onto IBM enterprise storage (DS8000 and DS6000) can offer some relief. Copy services between existing IBM ESS, the vertically scalable DS8000 and the modular DS6000 are all fully interoperable meaning you have the option to use lower cost storage as your copy target.

That means that we are free to make all changes to the physical disks without impacting the host systems, We can bring in new disks and get rid of old ones. We can consolidate small disks onto large ones. And all without impacting the host systems because the virtual disks don’t change. (click)

Now suppose you have two physical disk systems virtualized by the SAN Volume Controller. Let’s say that the green one is a high-end system from vendor “A” and the red one is a low-cost system from vendor “B”. You want to make a Point-in-time copy – what we call FlashCopy – of the primary data on the green. Because you have a virtualized environment (click), you can send that copy to the lower-cost red controller.
(click)
Now suppose you want to keep a continuous replica – what we call Peer-to-Peer Remote Copy (or PPRC) – at a remote site. Over at the remote site you have another high-end “green” disk system but you also have a lower-cost blue system from vendor “C”. Because you have virtualized your environment, (click) your continuous copy target can be on the lower cost system.

Finally, we’ll talk about Continuous Availability.

18. Global Mirror What is Global Mirror?
Designed to provide a continuous, asynchronous mirror of a set of data to a remote location.
Performed at a volume level.
What is Global Mirror typically used for?
For recovery sites at very long geographic distances, Global Mirror provides data integrity at a tight Recovery Point Objective.
Source
Target
Another Advanced Copy Service is Global Mirror – generally used in Continuous Availability scenarios. When you break down the cost of providing long-distance mirroring, one of the larger costs is the network that connects the two locations. Think about it. You spend a good deal of money building a very high speed SAN network for local access – to handle all the I/O’s that applications generate. Now you want to mirror that across the country – or across the continent. Synchronously mirroring all the updates would require a significant pipe. Global Mirror is designed to provide a continuous, asynchronous mirror of a set of data – at the volume level. For recovery sites at very long geographic distances, Global Mirror provides data integrity at a tight Recovery Point Objective without requiring that ever I/O be sent. (click)

So, Business Continuity – something we all have to do. Unfortunately, we can’t make that go away – but IBM does have a variety of unique technologies that can be used to make implementation much more flexible and cost effective. (click)
In Backup / Restore solutions, Tivoli Storage manager offers very efficient use of bandwidth and media utilization. (click)
Enhanced with SAN File System FlashCopy Image, the combined Backup / Restore solution can dramatically improve the RTO / RPO levels previously available for this cost. (click)
For Rapid Recovery solutions implemented on a physically consolidated DS8000 / DS6000 – or a logically consolidated SAN Volume Controller environment, using lower cost storage for copy targets can dramatically reduce the cost and make this level of BC solution more accessible to more of your data. (click)
And for Continuous Availability solutions, IBM’s use of asynchronous Global Mirror technology efficiently uses network bandwidth making these top-end solutions more affordable. Unique technologies from IBM reducing the pain of Business Continuity. (click)

That’s where ILM comes in. ILM not only helps you more effectively match the value of information to the cost of the storage – but also the valu of the information to the cost of the BC solution. Think about the storage pools in terms of BC tiers instead of just storage cost tiers. The left hand storage pool may have Global Mirror turned on. The middle Metro Mirror or FlashCopy. The right hand pool might have tape backup enhanced with snapshot. ILM is about matching value to cost – cost of storage and cost of recovery.
