The BladeCenter S has always supported drive bay modules on either side of the blade servers within the chassis, but that storage used to be direct-attached to adjacent server blades that also have internal system disks. All disks in the blade chassis, including the blades' internal disks, can now be shared among all servers in the chassis with direct point-to-point SAS connections, rather than a separate network, said Scott Tease, worldwide product marketing manager for IBM BladeCenter.
Customers can slot up to 12 drives in four three-drive hardware modules with a choice of 3.5-inch or 2.5-inch SAS or SATA. The highest-capacity configuration using SATA disks can hold up to 9 TB, while the highest performing configuration can offer 3 Gbps throughput using SAS drives.
IBM admitted the shared-storage update to the BladeCenter S is in part a competitive answer to Shorty's storage blade, but pointed out that performance in the HP box is limited to an internal GbE network while the shared SAS disks in the IBM system allow for native SAS throughput speeds of 3 Gbps. Meanwhile, IBM's list prices are comparable to both flavors of the BladeSystem c3000, at $2,599 for the chassis and $7,000 per pair of storage modules. HP says list pricing for the storage blade is $9,968. Pricing for the chassis starts at $3,481 according to HP's website. "The capacity that IBM provides in this form factor makes it a very powerful product," said IDC analyst Natalya Yezhkova.
Cracking the SMB market a channel challenge for IBM
Unlike some of the Fibre Channel external storage products IBM has positioned for the SMB market in the past, the pricing for the BladeCenter S looks to be more affordable to truly small businesses, according to Yezhkova. However, it's not clear through IDC's market research that the smallest of small businesses are necessarily picking up on shared or networked storage, yet.
"HP has a good message and good offerings in its All-in-One storage systems," she said, but IDC tracker numbers show that all of the All-in-One products, including the blade, have had run rates below $10 million per quarter so far.
IBM is also building its channel to reach SMBs with 80 Blade and Storage Solutions Centers (BSSC) throughout the country set up to demonstrate the product specifically to small businesses.
"Small business IT departments typically report through the CFO, and so we may be talking more to the financial organization than a technical organization," said Don Reczek, director of technology solutions for KDSA Consulting LLC. Reczek's company goes out of its way to make the demonstration and sales process "nonintimidating" for companies without specialized IT expertise.
Still, he said he expects much of the interest in the new storage blade to come from companies looking to set it up at remote and branch offices with management at a central data center. IBM seems to be anticipating this use case, as well. The management software for the BladeCenter S can be plugged into the same console used to manage the larger data center-class BladeCenter H chassis.
