Top tape library systems: Spectra Logic midrange and enterprise winner

Spectra Logic emerges as the top winner in the Quality Awards survey of tape library systems.

Spectra Logic was the winner of both the midrange and enterprise tape library system categories in the latest Storage magazine/SearchStorage.com Quality Awards service and reliability survey. The Quality Awards are designed to identify and recognize products that have proven their quality and reliability in actual use. Products are rated on a scale of 1.00 to 8.00, where 8.00 is the best score. A total of 331 respondents provided 372 midrange and enterprise-class tape library evaluations.



BUYING A TAPE LIBRARY SYSTEM

With tape library systems being relegated to a more limited and specialized data protection role in most shops, it would seem to be harder than ever for a tape library salesperson to get their foot in the door. Nonetheless, they seem to be doing a pretty good job of determining a customer's needs and delivering. For midrange libraries, Spectra Logic's 6.78 led the pack in the sales-force competence section of our survey; IBM Corp. and Hewlett-Packard (HP) Co. tied for second with a score of 6.26. Spectra's 7.25 for the statement "The vendor's sales support team is knowledgeable" was the highest, and only 7.00-plus, mark, propelling it to the highest rankings for all the statements in the rating category.

In the enterprise tape library division, Spectra Logic again swept, but with scores above 7.00 for all statements on the way to a 7.36 category rating -- an astonishing feat when you consider that the highest score we had seen previously in this category was a 6.53, which Spectra earned on the last survey. The keys for Spectra, again, were a knowledgeable sales support team (7.61) and a 7.50 rating for "My sales rep is knowledgeable about my industry."

IBM had another strong showing in sales-force competence with a total score of 6.34 highlighted by a 6.62 for the knowledgeable sales support team statement. Quantum Corp., rode three 6.00-plus and three high-5.00 ratings to a solid 6.09 third-place finish.

INITIAL PRODUCT QUALITY

It's been said there's nothing in a data center with more moving parts than a tape library. If any of those parts fails to mesh properly or misses its mark, a poor first impression is inevitable. The initial product quality section of our survey measures how quickly and easily a tape library got up and running and in production. The good news is that tape library vendors have risen to the occasion despite the mechanical nature of their products; when averaging all ratings for all vendors, this survey's roster of vendors received the highest scores ever for initial product quality in both the midrange and enterprise tape library categories.

Continuing its tour de force, Spectra Logic topped both groups with an even 7.00 in the midrange group and another eye-popping 7.50 to lead its enterprise peers. In the midrange group, Dell's very impressive 6.70 placed it second followed by another outstanding score of 6.61 from IBM. In the enterprise sector, HP's 6.52 earned second place, with Quantum just behind at 6.45 -- scores that could have been category winners in the past.

For enterprise tape libraries, respondents registered their particular satisfaction with high scores across the board for "I am satisfied with the level of professional services this product requires," "The product requires very little daily intervention" and "This product is easy to use." Midrange users gave their highest scores to the statements related to easy installation and configuration, as well as ease of use.

FEATURES AND FUNCTIONS

What a library can -- and can't -- do is the bottom line, and modern tape libraries are far from the one-trick ponies of yesteryear. Here again, Spectra Logic led a very strong group of product lines to some of the best scores yet in the product features rating category, with a midrange score of 6.82 and an enterprise score of 7.42.

For enterprise tape libraries, Quantum nosed out IBM for second (6.65 vs. 6.59), with HP (6.43) and Oracle (6.29) not far behind. Midrange scores were also striking; IBM's 6.59 trailed only Spectra, while Dell (6.38) and HP (6.36) were in a virtual tie for third.
Statements related to good design, scalability and management features were among the highest scorers for all vendors, but the blanket "Overall, this product's features meet my needs" statement came out on top for enterprise tape libraries. Spectra dominated with the only 7.00-plus scores, ranging from 7.00 to 7.63 for the eight statements in the category.

Midrange users were also pleased with overall feature sets, and rated design and management features highly.However, Spectra failed to sweep the features statements, thwarted by IBM's 6.52 for "This product loads and ejects tape efficiently."

HOW RELIABLE IS YOUR TAPE LIBRARY?

There's no test like time when measuring the reliability of a product, and our survey results indicate that tape libraries are doing a better job than ever at the daily grind of data center operations. For our enterprise tape libraries, the average of all scores is the highest yet on the five surveys we've conducted, and the midrange group's score was second to only one previous survey.

Spectra's 7.26 score in the product reliability category led the enterprise pack by a substantial margin (IBM was second with a 6.34 followed by Quantum's 6.18). While the midrange group was a little more competitive, Spectra's 6.67 placed it in front of IBM and Dell.

The enterprise-class tape libraries seem to be a step ahead of their more modest brethren in the product reliability ratings. All the enterprise vendors' product lines scored well across all eight statements in this category, with the top scores generally given for "This product requires very few unplanned patches/updates" and "The product meets my service-level requirement."

For all products and all statements, there were only five sub-6.00 scores.

With a narrower margin of victory than in other categories, Spectra Logic's midrange entries scored highest on six of the statements, ceding to IBM for "This product is rarely the cause of backup failures" and to Dell for "This product experiences very few bugs."

GETTING THE SUPPORT YOU NEED

One product may have a great feature list and be easy to get up and running and manage, but the day it decides to hiccup -- and that day will come -- the most important part of the product is likely to be how well it's supported. Most users can easily overlook minor problems if they're resolved quickly and effectively, but if they have to jump through hoops or search for missing manuals, even an otherwise exemplary product can quickly go south.

In the technical support category, Spectra Logic locked up its clean sweep in both the midrange and enterprise tape library systems, resoundingly so, with the highest scores recorded to date for tape libraries. Its 7.45 anchored a strong overall showing in the enterprise group, followed by IBM's solid 6.63 and Quantum just a hair behind with a 6.58 rating. Spectra topped 7.00 for eight statements in the category, with its highest marks for "This product is easy to service" and "Vendor's support personnel are knowledgeable." All vendors netted high ratings for having knowledgeable support personnel, punctuated by Quantum's 6.97 and IBM's 6.83 for that statement.

We found midrange tape library users to be almost as satisfied with the support their vendors provide. Dell posted a 6.47 as overall runner-up to Spectra Logic's 6.91, and tied Spectra with a 6.67 rating for the "Problems are resolved in a timely manner" statement.

WOULD YOU BUY THIS TAPE SYSTEM AGAIN?

In all our Quality Awards surveys we ask if respondents, armed with the knowledge they have now, would buy the same product again. Sometimes, these "buy again" results run counter to the overall survey scoring, suggesting that even if somewhat disappointing, the familiar is preferable to the unknown.

But this time the percentage of users who said they would make a repeat purchase hews closely to the rating category scores. In the enterprise group, 95% of Spectra Logic users said they would buy another tape library from that vendor -- hardly surprising given the other results. But IBM (86%), Quantum (83%) and HP (81%) also earned loyalty points among their users. Oracle was the laggard at 66%, perhaps reflecting some confusion over the management handoffs from StorageTek to Sun to Oracle over the past few years.

For midrange tape library systems, the level of satisfaction was equally encouraging for vendors, with Spectra Logic (88%) leading a tightly bunched group with scores all in the range of 82% to 88%.
