Oracle StorageTek SL8500 Number One in Big Tape Libraries

As ranked by DCIG 2014-15 Buyer's Guide

Several years ago at a crowded end user focused conference, the latest tape library innovation was unveiled from behind a waterfall curtain and throngs of attendees rushed the stage to catch a glimpse. Fast forward to today, and in spite of what some disk suppliers have been saying, tape is still necessary and projected to grow as the need for storage capacity expands in the new big data era.
 
Tape storage has long had notable advantages such as reliability, security and inherent cost savings, and with the release of the 2014-15 Big Data Tape Storage Buyer’s Guide, it is new and emerging innovations around hardware encryption, partitioning technologies, REST (Representational State Transfer) APIs and secondary cloud storage that are making tape more attractive to end users than ever before.
 
“There are many that may believe that tape is dead, and they are sorely mistaken,” said Jerome Wendt, president and lead analyst, DCIG, LLC. “Tape storage continues to shine for data at rest, and long term data availability continues to keep tape not just appealing but viable. The newest DCIG 2014-15 Big Data Tape Library Buyer’s Guide is the ideal tape library resource available in the market, and represents all the significant solutions. Like our other buyer’s guides, this one will be an indispensable aid for users looking to eliminate unnecessary research cycles and quickly find a tape library that best meets their unique needs.”
 
For the DCIG 2014-15 Big Data Tape Library Buyer’s Guide, DCIG evaluates more than 40 offerings from 8 companies. After an initial survey containing more than 100 questions was completed, product capabilities were assessed based on data provided by the vendor, prior DCIG research, and information available in the public domain. Products were then evaluated on more than 80 features. After scores were compiled, products were ranked Best-in-Class, Recommended”, Excellent, Good, or Basic across functionality and capability relative to the other products included in the guide.
 
The intent for this guide, as with all DCIG buyer’s guides, is to provide an ‘at-a-glance’ comparison from which end users can select the most appropriate solution for their existing needs. It also provides perspective on how solutions from less well known tape library providers compare against established and better known brands.

The Oracle StorageTek SL8500 ranked highest of the models evaluated in the guide, earning the Best-In-Class ranking. It scales to over 850PB raw (uncompressed) data and, assuming the LTO-6 2.5:1 data compression standard is applied, can store a staggering 2EBs or more of data. This coupled with its support for 10GbE and 8Gb FC networking connectivity; redundant robotics, fan and power supplies; active-active I/O controllers; and, support for advanced functions such as REST object storage and tape drive virtualization drove this model to the top of the guide’s rankings.

Oracle StorageTek SL8500 stood out in ollowing ways from other tape libraries:

  • Scales to over 2EB of data (compressed)
  • Scales to hundreds of drives and over one hundred thousand tape cartridges
  • Supports the majority of backup and archive software packages available
  • Supports 10GbE
  • Offers REST APIs
  • Offers tape virtualization

In doing its research, DCIG uncovered some interesting statistics about tape libraries in general:

  • 100% support the LTO-5 and LTO-6 formats
  • 100% support a 8Gb FC and 6Gb SAS interfaces
  • 95% have customer replaceable tape drives
  • 83% support hot swappable tape drives
  • 67% are rack mountable
  • 65% support at least 100 tape cartridge slots
  • 40% support two different tape drive formats
  • 38% support at least 1PB of storage capacity (70% more than the previous Guide)
  • 38% support half-height tape drives
  • 19% offer redundant controllers

DCIG 2014-15 Big Data Tape Library Guide achieves the following objectives:

  • Provides an objective, third party evaluation of tape libraries that evaluates and scores their features from an end user’s perspective
  • Scores and ranks features on each tape library based on criteria that matter most to end users
  • Provides a standardized data sheet for each of the tape libraries so users may do quick side-by-side comparisons of products
  • Provides insights into what features on a tape library will result in improved availability and increased storage capacities
  • Provides insight into which tape libraries are supported by popular archiving and backup software products
  • Gives any organization a solid foundation for getting competitive bids from different providers that are based on ‘apples-to-apples’ comparisons

With nearly one out of every four models surveyed in the Buyer’s Guide supporting the ability to store data directly to tape using REST, and nine models supporting the ability to store data to secondary cloud storage, the combination offers a significant step forward for tape storage,” added Wendt.  “We know our latest Buyer’s Guide will help end users cut both cost and time from the evaluation and purchase process as they look for solutions to best meet their long term archive, storage and secondary storage needs in a cost-effective way.”

Each tape library had to meet the following criteria:

  • Support a minimum of 24 tape drive cartridge slots
  • Support at least two tape drives
  • Support LTO-4 or later technology
  • Sufficient information available for DCIG to make meaningful decisions
  • Shipping by October 31, 2013
