And data deduplication is the key to using more disk more cost effectively! Deduplication technologies have evolved considerably over the last few years and have delivered the promise of improving backup and recovery operations while consuming less storage and utilizing infrastructure, such as network bandwidth, more efficiently and improving SLAs. The benefits provided by deduplication deliver a very compelling ROI, reduce TCO and provide opportunities to save money and accomplish backup and recovery goals more efficiently. And unlike some other technologies, difficult economic times actually magnify the value propositions delivered by deduplication. Now is the time, when budgets and spending are tight, for deduplication, a technology that can actually save you money.

How ProtecTIER works Backup with Inline deduplication New Data Stream Repository HyperFactor™ Memory Resident Index ProtecTIER™ Server The major difference between ProtecTIER and other standard VTLs is ProtecTIER’s unique patent pending factoring algorithm called HyperFactor. HyperFactor is the data de-duplication technology developed by Diligent Technologies that allows you to store a lot more backup data onto a smaller amount of disk. Here’s how HyperFactor works. As we build the slide, you’ll see that there are unique blocks of data in the repository. HyperFactor keeps track of this data with a memory resident index, like a table of contents, that can map the contents of a 1PB repository in only 4GB of memory. That 250,000:1 ratio between the repository and the index is a significant differentiator and has orders of magnitude greater granularity than anything in the market place. And as we build the slide, you’ll see a stream of data coming from one of the backup servers. This stream contains some data that already exists (as represented by the multi colored icons) and some data that’s new (as represented by the tan icons). HyperFactor is an inline data de-duplicator. As the data stream passes through the HyperFactor data de-duplication engine, HyperFactor will be looking for data that is “similar” to data it has stored before. PAUSE I use the word “similar” because it’s not identical, and that’s because part of the algorithm’s power is that it uses similarities instead of identicals to achieve unmatched performance. The most similar pattern in the repository is found with no I/O operations and then that data into brought to the server to do a computational compare and then store the delta. This is performed without impacting the search time, regardless of the repository size. Because there is no I/O required, we’re actually performing a memory search on an index, the search time difference will not be noticeable whether it’s 10TB or a petabyte. The location and similarity of the data isn’t affected by naming conventions, shifts or offsets in position, because we are looking at the byte level of the data. Customers often ask “What happens if the index disappears?” Remember the index is used to locate similarity in the repository, and in fact it’s not used in the restore process at all. If the backup applications data stream needed to be restored, this data that exists in the repository is self describing which means that a restore can be done without the index since the data itself tells me what is required to restore the stream. As we said, the index is important in finding similarity, not only is it in the server memory, but it’s also duplicated in two places on RAID protected disk and synchronized. “Filtered” data Backup with Inline deduplication Up to 1400MB/sec per server or 2000MB/sec with 2 node cluster! Only 4GB needed to map 1PB of physical disk! Backup Servers

ProtecTIER Deduplication Operation and Results Example Backup application writes data to ProtecTIER as it would to tape Only unique data is stored, existing duplicate data is referenced When data objects expire, references are removed and free space is reclaimed and reused Backup Amount Amount Dedupe Event Received Stored Ratio First Full Backup 1 TB 250 GB 4:1 Incremental Backup 100 GB 10 GB 4.2:1 Incremental Backup 100 GB 10 GB 4.4:1 1 2 3 4 5 Second Full Backup 1 TB 10 GB 7.8:1 Backups, especially full backups, are notoriously inefficient processes that repetitively send large amounts of data, mostly redundant, over and over again. Deduplication can eliminate redundant data and dramatically reduce the amount of storage needed for backups An important point to note about this slide is that the effect of deduplication is not instant but grows over time. The more data that is stored and the longer it is retained, the greater the deduplication ratio (the difference between the received over the amount actually stored) becomes and the more capacity is saved.

ProtecTIER Many-to-One Replication Overview Up to 12 Branch Offices (spokes): Gateways and/or Appliances 1 target (hub): Appliance, Gateway, single or two-node cluster IP based NR links This slides shows the power of deduplication to protect data stored at a large number of smaller remote site and replicate that data back to a central location for additional protection and Disaster Recovery purposes. The amount of bandwidth needed is very small because only new unique data needs to be transmitted over the line since existing data is already stored at the hub.

ProtecTIER Differentiation

ProtecTIER Advantage: Data Integrity Unique and patented HyperFactor® deduplication technology The only production proven deduplication solution not based on a hash algorithm Designed for 100% data integrity Bit for bit comparison of data to ensure data is a duplicate Can NEVER lose data due to a hash collision A major differentiator for ProtecTIER versus other hash-based deduplication systems is IBM’s unique and patented HyperFactor deduplication algorithm. HyperFactor was designed to provide 100% data integrity by doing a bit for bit comparison of data before declaring it a duplicate and not relying on a hash algorithm. HyperFactor can never lose data due to a hash collision unlike most other products on the market. Vendors of hash-based deduplication products will claim the odds of losing data due to a hash collision is the same odds as winning the lottery. That analogy is true as long as you admit that with every backup job you get thousands and thousands of lottery tickets. IT organizations have hit “the data loss lottery” in the past and will hit it again in the future. A hash collision will not only result in the loss of some data, it could cause corruption that results in the loss of all your backup data. Are you willing to take that risk? Some vendors claim to have “data Invulnerability” mechanisms to avoid hash collisions. However, performing these optional extra checks significantly slow down system performance and are usually disabled by the vendor and/or the customer to maximize speed. ProtecTIER delivers both high performance and data integrity. You don’t have to choose one or the other. Although the chance of losing data from a hash collision is low, it is NOT ZERO as it is with a ProtecTIER solution

ProtecTIER Advantage: Restore Performance Restoring data from a ProtecTIER solution is even FASTER than backing up ProtecTIER can easily restore at 2800MB/sec! High restore performance not limited to certain backup applications or specific data sets like other vendors High restore performance achieved on real data with realistic 20% change rate in production environments Never requires agents on backup servers The performance stated by IBM for its ProtecTIER solutions is always realistic numbers that are achievable in real production environments. This is quite unlike our competitors who claim exaggerated performance numbers that can not be achieved in real production environments. Most even acknowledge this by hiding in the fine print a disclaimer like “these are maximum benchmark speeds that should not be used for configuration purposes” Other vendor’s “CPU-centric” architectures are optimized for processing hashes not moving data

ProtecTIER Advantage: Scalability A single ProtecTIER system can support up to 1 Petabyte of useable capacity ProtecTIER supports the use of any IBM storage system (DS8000, DS5000, XIV, etc.) and most third party storage systems for the repository IBM has hundreds of ProtecTIER systems with over 100TBs of useable capacity in production environments throughout the world IBM always states “Useable Capacity” and never uses the deceptive “RAW capacity” terms like other vendors The capacity stated by IBM for its ProtecTIER solutions is always “Useable Capacity”. This is the real capacity that can be used by the system to store data. For example, if you have 10TB or useable capacity and achieve a deduplication ration of 20:1, you can store 200TB of backup data. Most of our competitors use “RAW capacity” to make their systems seem bigger than they really are. RAW capacity is all of the disk drives summed up within a system in its maximum configuration. It does not take into consideration the effects of RAID, spares, and capacity needed for the application, metadata and other requirements that take away from the actual useable capacity of the system Some vendors use RAW capacity to deceive you and they should not be trusted. In addition, these vendors often make big claims about “Logical capacity” which is taking the usable capacity and multiplying it by a deduplication ratio 50 or more. While achieving a dedupe ratio of 50 is possible, it is not common. Vendors that use these cheap tricks to deceive you should not be trusted! The hidden costs associated with managing, maintaining, powering and cooling multiple appliances is significant and should not be ignored!

ProtecTIER Advantage: Global Deduplication ProtecTIER Cluster with true Global Deduplication has been Generally Available and in production since 2008 Supported with all major backup applications and available for all Open Systems, System z and System I platforms No agents or backup server upgrades required Other vendor’s Global Deduplication capabilities are immature and incomplete with very few if any systems in production Other vendor’s Global Dedupe restricted to certain models, only with NetBackup OST and require agents to be installed Many vendors claim to have Global Deduplication but create multiple separate repositories that may contain redundant data!

ProtecTIER Advantage: Inline Deduplication Example: Disk activity needed to ingest and deduplicate 10 TBs of backup data Post Process Approach: Deduplicate after Storing Requires: > storage > I/Os > Time > Effort > Admin Hash-based Post Process 10 TB Data Write 10 TB 2x Read 10 TB For every 10 Terabytes of data (for example) sent by the backup application server, a DeltaStor server must write 10 Terabytes of data to disk, read 10 Terabytes of data form disk, and then read another 10 Terabytes of data from disk. It must also read and write from its index database and write some amount of pointers. All this reading and writing will significantly hammer the SATA drives. ProtecTIER, on the other hand, will only read or write 10TBs of data for every 10 Terabytes of data sent by the backup application server. This is at least one third less disk activity on more reliable FC disks. ProtecTIER Inline Approach: Deduplicate before Storing Results: simple faster easier cheaper efficient Read or Write 10 TB 10 TB Data HyperFactor 1x
