Flash options for the array or server

As the price of flash drops, shops capitalize on its high performance to accelerate needy applications. Our Essential Guide to SSD implementation looks at the flash options when it comes to deployment.


Solid-state storage is showing up in enterprise servers and storage in a variety of different configurations. Server-side flash options are popular because they put the data on flash storage physically close to the applications that require it most, reducing latency. However, server-side flash is typically directly attached to a single server, which does not allow applications running on additional servers access to flash. This can be accomplished with software, but that adds latency back into the equation. Flash storage is, of course, also being implemented in arrays. This can mean a hybrid array with mostly hard disks and a flash tier for frequently accessed information or an all-flash array. Our Essential Guide to SSD implementation looks at the variety of ways flash storage is showing up in servers and storage today. It also compares and contrasts each of the different flash options, so you can make an informed decision about what's right for your organization.

1Server-side flash-

Server-side flash puts solid-state performance close to apps

There are a number of ways that flash can be added on the server side: in a typical hard disk format, by connecting directly to the PCIe bus, or by plugging into the server's DIMM slots (known as "memory-channel storage"). All of these flash options have their own own pros and cons.


Server-side storage takes the main stage

As flash technology has continued to evolve, server-side storage has seen an increase in interest as compared to legacy storage architectures. Continue Reading
