IBM ProtecTIER: Optimized for Tivoli Storage Manager

Deduplication took the market by storm several years ago, and backup hasn’t been the same since. With the ability to eradicate duplicate data in duplication-prone backups, deduplication made it practical to store large amounts of backup data on disk instead of tape. In short order, a number of vendors marched into the market spotlight offering products with tremendous efficiency claims, great throughput rates, and greater tolerance for the too often erratic throughput of backup jobs that was a thorn in the side for traditional tape. Today, deduplicating backup storage appliances are a common site in data centers of all types and sizes.

But deduplicating data is a tricky science. It is often not as simple as just finding matching runs of similar data. Backup applications and modifications to data can sprinkle data streams with mismatched bits and pieces, making deduplication much more challenging. The problem is worst for Virtual Tape Libraries (VTLs) that emulate traditional tape. Since they emulate tape, backup applications use all of their traditional tape formatting. Such formatting is designed to compensate for tape shortcomings and allow faster and better application access to data on tape, but it creates noise for deduplication.

The best products on the market recognize this challenge and have built “parsers” for every backup application – technology that recognizes the metadata within the backup stream and enables the backup storage appliance to read around it.

In 2012, IBM introduced a parser for IBM’s leading backup application Tivoli Storage Manager (TSM) in their ProtecTIER line of backup storage solutions. TSM has long had a reputation for a noisy tape format. That format enables richer data interaction than many competitors, but it creates enormous challenges for deduplication.

At IBM’s invitation, in November of 2012, Taneja Group Labs put ProtecTIER through the paces to evaluate whether this parser for the ProtecTIER family makes a difference. Our findings: Clearly it does; in our highly structured lab exercise, ProtecTIER looked fully poised to deliver advertised deduplication for TSM environments. In our case, we observed a reasonable 10X to 20X deduplication range for real world Microsoft Exchange data.

HP StoreVirtual Virtual Storage Appliance - The VSA for scalable VM density (TVS)

Virtual Storage Appliances (VSAs) have been around for a while – just over 5 years ago, the earliest vendors started to sample market interest in this technology.  In theory, the market was interested, but perhaps more so on paper than in actual adoption during those early days.  Regardless, that interest drove more vendors to release VSAs and today there are dozens of Virtual Storage Appliances on the market.  Many of these are focused on capabilities such as backup, but at least a handful can serve as primary storage beneath the virtual infrastructure.

The primary storage VSAs on the market came about as product or marketing experiments; perhaps to let customers experience a storage system without making a full investment, allow customers to ingest rogue virtual infrastructure storage back into their existing storage infrastructure, or enable consistent storage management as customers deployed workloads with remote service providers.

For certain, many of these primary storage VSAs have never found their footing, and still languish as a neglected technology in a dusty corner of a vendor’s product portfolio.  But there have been exceptions.  One is HP StoreVirtual.  HP has been quite serious about delivering StoreVirtual as a real storage solution with hefty capabilities.  StoreVirtual is one of HP’s several converged storage technologies that is blurring the boundaries between storage and compute, and helping customer infrastructures to scale and adapt while maintaining maximum efficiency.  The popular StoreVirtual product line comes in a variety of physical formats, from entry-level 1U 4 drive systems to extremely dense BladeSystem SANs.  Approximately 5 years ago, the StoreVirtual software foundation was also released in Virtual Storage Appliance form.  This StoreVirtual VSA is a full storage system that looks, acts, and functions just like its physical StoreVirtual brethren.  The intent behind HP’s StoreVirtual VSA is increased ease of use, increased storage functionality in the virtual infrastructure, and greater adaptability, within a dense footprint that can make use of any available storage resources (direct attached server storage or networked storage).  HP claims that StoreVirtual VSA leads the market in ease of use, performance, efficiency, and storage capabilities – all of which makes it ideally positioned to service primary workloads in the data center.

In this Technology Validation, we set out to examine StoreVirtual VSA, and through comparison to another leading virtual storage appliance (VMware’s vSphere Storage Appliance – VMware VSA) evaluate the effectiveness of StoreVirtual VSA’s architecture in enabling superior, primary-workload-ready storage in the virtual infrastructure.  With an eye on ease of use, efficiency, and flexibility, we put StoreVirtual VSA and VMware vSphere Storage Appliance through a detailed examination that included both a review of functionality and a hands-on lab examination of performance, scalability, resiliency, and ease of use.
