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.
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 caching software lifts flash output by lowering network file traffic and latency. Server-side caching takes place at the file level, OS level or hypervisor level. Continue Reading
Hybrid and all-flash arrays allow a variety of apps to access data on flash storage
Array-based flash storage ranges from home-brewed flash options created by adding flash to an existing array, to arrays that have been designed from the ground up to maximize the potential of flash storage.
The all-flash array market has exploded in recent years thanks to expanded flash options from vendors. Here's what you need to know before buying one. Continue Reading
Once upon a time, all-flash array vendors would compete based on price and speed. But thanks to growing workloads, consumers are now looking for all that and more. Continue Reading

Learn where flash makes the most sense for your organization's needs
The final section of our guide to offers information about how the different implementations of flash storage stack up against each other, so you can choose the best approach for your particular needs.
Hybrid arrays and servers are the most common spots flash is showing up in enterprises as all-flash arrays gain a foothold. Common workloads include virtual environments and databases. Continue Reading
Hybrid arrays are losing out to faster, more efficient flash-only products whose pricing no longer breaks the bank. Continue Reading
