Gartner Agrees With IDC on WW Disk System Growth: Between 10% and 11%

But some company's figures radically different

Worldwide external controller-based (ECB) disk storage revenue totaled $5.1 billion in the third quarter of 2011, a 10.4 percent increase from revenue of $4.6 billion in the third quarter of 2010, according to Gartner, Inc.’s report Quarterly Statistics: Disk Array Storage, All Regions, 3Q11 Update.

Although the worldwide ECB disk storage market showed positive revenue growth for the seventh quarter in a row, the market did show signs of slowing down.

"The third-quarter, year-over-year worldwide growth rate was the smallest percentage increase in the past seven quarters," said Roger Cox, research vice president at Gartner. "The North American region, which grew 6.7 percent in the third quarter, appears to be finally laboring under the weight of an extremely sluggish economy. Moreover, the prolonged debate and uncertainty around the debt ceiling as the quarter came to an end also had a negative influence on third-quarter revenue."

Although the Asia/Pacific and Latin American regions produced the largest year-over-year revenue gains at 23 percent and 15.3 percent, respectively, the EMEA region continued to achieve results that defied its economic woes. These three regions in particular benefit from the conversion of DAS infrastructures to fabric attached storage (FAS) infrastructures associated with the transition to a virtualized server environment, as well as the ongoing movement from tape to disk in order to modernize inefficient backup/recovery methodologies.

Led by EMC, the branded sales of four vendors, including IBM, HP and Hitachi/HDS, gained market share in the third quarter of 2011. EMC’s strength remained its broad ECB market coverage. EMC was the leading vendor in the block-access and Special Purpose Disk Active Archiving System (PDAAS) segments. Propelled by the Isilon acquisition and the new VNX series, EMC garnered for the first time the top position in the NAS segment.

 (1) EMC revenue excludes OEM revenue from Dell
  and Fujitsu Technology Solutions.
 (2) Hitachi/HDS revenue excludes OEM revenue from HP.
 (3) NetApp revenue excludes ONTAP OEM revenue
  from IBM and Engenio OEM revenue.
 (4) Fujitsu’s branded revenue does not include products
  sold under the EMC and NetApp brands.

Bolstered by strong year-over-year growth results by IBM’s flagship DS8000 series in conjunction with broad acceptance of its XIV Gen3 and Storwize V7000 modular storage systems, IBM overcame the decline in DS5000/DS3000 revenue sourced from NetApp to increase its share by a modest 0.1 percent.

Driven by the performance of the P4000 G2 SAN Solution Platforms (formerly LeftHand Networks) and 3PAR Storage Systems, HP gained almost one percentage point in market share, offsetting the drop in EVA revenue. The high-end Virtual Storage Platform (VSP) remained the engine behind Hitachi/HDS performance, enabling it to gain 0.6 percentage points of share in the third quarter of 2011.

NetApp’s third-quarter results reflect an overdependence on a few large customers, limited geographic coverage in high-growth countries and increased competition from Dell, EMC, HP and IBM in the midrange modular ECB disk array market segment. In addition, Gartner analysts said NetApp’s storage solutions that leverage the branded E-Series are yet to produce meaningful revenue.

Even though Dell is making notable strides with its Compellent acquisition, and the EqualLogic PS-Series results remain robust, the falloff in cobranded Dell/EMC CX-Series revenue, coupled with its deteriorating position in the NAS segment, inhibited Dell’s overall ECB revenue growth.

The third quarter of 2011 was the first quarter where the disengagement from Hitachi Data Systems was not impacting Oracle’s ECB disk storage results. Nevertheless, and even with credit for the Pillar Axiom acquisition, Oracle lost 0.3 percent share.

In the ECB disk storage market segment, the block-access segment represented 77.9 percent of the total market and increased 9 percent year over year in third quarter of 2011. The file-access segment represented 21.3 percent of the total market and was up 15.5 percent year over year. The SPDASS segment represented 0.7 percent of the total market was up 22.1 percent year over year. Vendor pricing and discounting were consistent with historic trends, with the price per terabyte declining 16.6 percent. The HDD shortfall caused by the floods in Thailand did not have an impact on HDD supply or third-quarter 2011 ECB disk storage system revenue results.

Gartner ECB disk storage reports reflect vendor-branded hardware-only revenue, as well as hardware revenue associated with financial leases and managed services. Optional and separately priced storage software revenue and storage area network infrastructure components are excluded.

Comments

Gartner and IDC do not have exactly the same way to calculate the data concerning the WW external disk system market. But some differences in their figures are difficult to be understandable.

Three examples on the percentage of revenues growth from 3Q10 to 3Q11 for both analyst companies:

  • NetApp at +4.1% for Gartner and +16.5% for IDC, even if NetApp revenue excludes ONTAP OEM revenue from IBM and Engenio OEM revenue for Gartner
  • HP at +20.4% for Gartner and +13.1% IDC
  • Dell up 3.1% for Gartner and down 2.6% for IDC
The two analyst firms also do not agree at all on the NAS market. IDC put EMC as number one since many years and here Gartner with the top rank for the first time as Isilon was added to the figure. Once more, they don't agree on definition as it depends if you count for NAS a system being connected or not to a gateway.
