Building and selling servers is one thing. After all, the systems your SMBs customers are buying employ many of the same technologies you see on the desktop. Of course, the components that go into them are designed from the ground-up to be more robust. But designing and deploying storage systems is another animal entirely. You’re dealing with data—irreplaceable information vital to the way your customers do business. To say that it’s important to pick the right components, build in the right redundancy, and ensure long-term reliability would be an understatement. We’re going to show you how.
High-Capacity Storage. LSI’s SAS 9211-8i serves up eight 6 Gb/s SAS ports internally, supporting twice as many drives per port compared to last generation’s 3 Gb/s host bus adapters.
The pace at which storage technology evolves is generally fairly methodical. Up until recently, literally all of the storage media you sold centered on conventional rotating platters. Even today, the fastest magnetic drives are unable to saturate the Serial ATA connections integrated onto every modern motherboard.
But falling prices on flash-based solid state NAND memory have led to an upsurge in SSD adoption. As we’ve discussed in the past, SSDs have the potential to drastically improve the performance of your customers’ storage subsystems, especially in the enterprise, where heavy I/O workloads really benefit from the technology’s unprecedented IOps throughput.
We all know that price is a relative measurement though, and while SSDs are more affordable now than they have ever been before, the cost per gigabyte of solid state storage is significantly higher than more familiar hard drives. This is actually good news. According to IDC, the increased cost of SSDs and the capacity advantages of hard drives mean the two formats will have a complementary relationship in the storage business, rather than a competitive one.
Between SSDs and conventional hard drives, the storage space has seen significant innovation in the past couple of years. If you’re selling storage solutions and haven’t yet explored the dynamics of magnetic and solid state drives, then it’s definitely time to revisit the fundamentals of storage using hardware that’ll improve the way your customers store and protect their mission-critical files.
Robust Entry-Level RAID. With support for SAS and SATA hard drives, RAID 1, 5, 6, 10, 50, and 60, Intel’s four-port RS2BL040 is an excellent controller for SMB-class servers and workstations.
What Are SMBs Looking For?
Before we dive too deeply into the technical nuts and bolts of today’s landscape, it’s important to talk about what SMBs are looking for in a storage system. “If I were to characterize what businesses want, in one word, it would be efficiency,” says David Graas, technical marketing manager at LSI. “They’re trying to get the most for the hardware cost, which is why leveraging hardware is one of the primary goals of an integrator in a system config. Being able to produce the lowest-cost design is how they win the business.” Naturally, it’s important to still meet the needs of the customer, so the VAR’s job becomes addressing functionality while keeping a handle on cost.
“When I talk to system integrators and resellers at trade shows, I try to emphasize building storage based on the application they’re trying to support.” In other words, if your customer needs a certain level of performance, you have to think critically about balance. Not only does that include the right processors, memory, and motherboard, but also storage. Is there a capacity requirement? How much capacity? Does the storage subsystem need to be expandable as the customer’s data burgeons, or are you looking at minimal growth? Then there’s the performance expectation. If an application requires a certain rate of throughput to sustain its operation, that’s what you need to be looking at.
All of these questions answered will begin to lead you down the path your customer should be taking. “If you determine that your customer’s application is more capacity-driven, and the performance levels aren’t as extreme, then I need to be looking at a solution taking advantage of higher-capacity, lower-RPM hard drives,” says LSI’s Graas. “They have a lower cost per gigabyte and they facilitate the most storage space in the fewest possible units, like 2TB drives. They aren’t the highest-performing, but based on the application, it makes the most sense to consider that type of storage. This is actually what a majority of what our channel customers are using—large SATA disks. Then they look to the RAID controller to team those drives together, matching the performance needs of the application.”
Of course, there’s a flip-side to that coin. Web servers and transactional databases (like SQL and Exchange servers) have a large client load. The capacity these environments require doesn’t change dramatically. But the randomized performance characteristics are critical. So, be on the lookout for a higher class of storage—a more advanced controller, as well as a higher-RPM SAS infrastructure capable of better performance in those randomized I/O applications. There’s naturally an increased cost that goes hand-in-hand with addressing an I/O-sensitive app, but that’s part of Graas’ education message to resellers. “We’re talking to customers in the channel about how to intelligently architect these types of storage solutions based on the application, rather than just slapping hardware together, picking just any controller out of a catalog, and the drives that are on sale.”
