NAS storage systems Quality Awards: EMC and IBM take top spots

Take a closer look at the results of the fifth NAS system Quality Awards. Find out why NAS storage systems are so reliable and why users ranked them so high.

In general, respondents to the Storage magazine/SearchStorage.com Quality Awards surveys have been happy with their network-attached storage (NAS) systems. In the past five years that NAS products have appeared on the survey, they have come out with high scores. And this year, scores for NAS storage systems and NAS groups were higher than ever.

EMC Corp. is the winner in the enterprise group this year with a winning score at an average of 6.80, the highest enterprise NAS score in the history of the survey. In the last Quality Awards Survey, EMC came in second place. The second and third place vendors this year were NetApp Inc. with an average score of 6.66 and Dell Inc. with an average score of 6.41.

IBM is the first-time winner in the midrange NAS category with an average score of 7.15, and that too is the highest score recorded for the midrange category, and the second highest overall score in all of the product categories in the past five years of the Quality Awards Survey. The second place winner in the midrange NAS category is EMC with a score of 6.70, followed by NetApp at 6.63, Hewlett-Packard (HP) Co. at 6.42 and Dell at 6.09.

The NAS buying experience

When Billy Joel sang "Get it right the first time, that's the main thing" it's unlikely he was shopping for a NAS system, but for system vendors Joel's line could be an anthem. Getting off on the right foot -- which for users means working with a knowledgeable and prepared sales team -- will often set the tone for the user's experience with the product. Judging by the improving scores in the sales-force competence rating category, vendors continue to improve their sales support efforts.

In the enterprise group, EMC launched its sweep of all categories with an overall 6.67 score for sales-force competence. EMC's highest scores were for the statements "My sales rep is knowledgeable about my industry" (6.78) and "The vendor's sales support team is knowledgeable" (6.73), but its scoring was very consistent for all statements in the category. NetApp's 6.48 placed it second, followed by Dell (6.33); both of those firms received their top marks for the knowledgeable sales support team item.

Among midrange systems, IBM made a clean sweep of the rating categories, matching EMC's enterprise-winning 6.67 score in the sales-force competence category. IBM's performance was highlighted by the only 7.00-plus score for sales-force competence statements, snagging a 7.08 for its knowledgeable sales support team. EMC's midrange entry finished just behind IBM with a 6.63 average tally; NetApp (6.29), HP (6.21) and Dell (5.76) filled out the field.

Lasting impressions of NAS systems

The sales effort may be the first step in the NAS deployment process, but the most lasting impression may be formed when the system is uncrated and cranked up for the first time. The initial product quality rating category endeavors to capture those impressions.

EMC topped off its excellent initial product quality ratings in the enterprise group with a 7.02 for "I am satisfied with the level of professional services this product requires" and came within a hair of the 7.00 mark with a 6.98 for "This product was installed without any defects." NetApp and Dell also showed strength in this category, scoring 6.70 and 6.64, respectively. NetApp's top mark (6.89) was for the statement about installing without defects; Dell's 6.82 for "This product was easy to get up and running" was second to only EMC's 6.90, which seems appropriate as Dell resells many EMC NAS models.

Among midrange NAS systems, IBM obviously made some good first impressions as it scored over 7.00 for all statements in the initial product quality category for a record-breaking average of 7.32. IBM's best statement rating was a staggering 7.52 for "This product was installed without any defects." Kudos to IBM and all the vendors represented here, as the average category scores were all very good, ranging from Dell's 6.41 to NetApp's 6.71.

Specs, speeds and feeds

Once past first impressions, the bottom line for any storage system is whether it does what you need it to do. In the product features category, we ask users to consider the functionality of their systems and whether the features meet their needs.

EMC's win in the enterprise group was by the slimmest of margins: 6.86 vs. NetApp's 6.85 -- essentially a dead heat. Both vendors notched 7.00-plus statement scores: EMC (7.05) for "This product's capacity scales to meet my needs" and NetApp (7.03) for "This product's snapshot features meet my needs" (a traditional NetApp strength). "The technology is very feature-rich and impressive," commented one NetApp user.

In the feature battle of these behemoths, it might be easy to overlook Dell, but the company fared quite well in this category with a noteworthy overall average of 6.41.

Among midrange NAS products, IBM was once again a formidable force with statement scores ranging from a "low" of 7.14 up to 7.36. It all added up to a stunning 7.25 features category average and a relatively easy win over EMC (6.84) and NetApp (6.59) with scores that would have ranked first in previous Quality Awards iterations. EMC's score received a boost from a 7.11 for the "This product's capacity scales to meet my needs."

NAS storage systems are reliable

Whether it's measured by four-nines, five-nines or some other yardstick, there's one thing a storage shop expects its NAS system to do: run and run. The product reliability rating section collects responses on just how satisfied users are with the reliability of their NAS boxes -- and they seem to be quite satisfied indeed.

EMC led a trio of solid enterprise NAS scores with a 6.86 for the product reliability category, highlighted by its two 7.00 statement scores for "The product meets my service-level requirement" and "This product requires very few unplanned patches." One survey respondent whose company has "several dozen" EMC boxes installed noted he was "extremely pleased and always [has] been regarding the reliability and scalability of EMC systems."

NetApp, with its 6.70 category average, posted statement ratings mostly in the mid- to high 6.00 range, while Dell was nearly as good, averaging 6.49.

IBM continued its mastery of the midrange with another solid performance across the board and a category score of 7.32. NetApp was well behind but with an outstanding 6.88, which would have been enough to cop top honors for reliability in any of our previous NAS Quality Awards. EMC wasn't far behind NetApp with a very sturdy 6.79.

NAS support teams are on top of their game

Crossed fingers, a rabbit's foot or a four-leaf clover might help deter the downtime demons, but a dependable support team is usually a better bet. Inadequate technical support can turn an otherwise good product experience bad in no time, but this crop of NAS vendors seems intent on delivering good products backed by good support.

EMC's enterprise-leading technical support category score of 6.76 was also the highest we've ever seen for enterprise NAS. EMC pulled itself up by its bootstraps in this category, improving on its past middle-of-the-pack finishes in tech support ratings. A user needs to know what to expect, and EMC is apparently doing a good job of delivering on expectations, with a 7.08 for "Vendor supplies support as contractually specified." Once again, NetApp notched an impressive average score of 6.57 for the category; Dell also did well, posting a 6.16.

The big news in the midrange NAS group is that IBM didn't score more than 7.00 on every statement, although its two sub-7.00 scores were hardly bumps on its road to a 7.18 technical support score. That's another record for IBM, as it's the highest support score ever achieved by a NAS vendor (midrange or enterprise). NetApp was next with a 6.69, which would have been good enough to lead most of the previous midrange NAS packs, while EMC copped another third-place finish with an excellent 6.57.

Will NAS be a repeat performance?

As usual, we followed up our category statements with a basic question: All things considered, would you buy this product again? The results don't always match up with other scores, but they're still good indicators of loyalty and satisfaction.

Nine out of 10 of our enterprise NAS evaluators who have EMC systems would go the same route again; not surprising considering how happy they appear to be with the products. On the midrange side, IBM backed up its impressive category scores with a 93% "buy again" response.

Over the course of five NAS Quality Awards surveys, we've seen user satisfaction -- as reflected by their product ratings -- rise. With so much focus on file storage growth, it'll be interesting to see how well the vendors can respond to new and more demanding needs.
