    Healthcare VDI environments can work well with flash storage. Expert Brien Posey looks at issues to consider, such as whether to choose an all-flash array or flash storage tier. Continue Reading

  • Server-side caching defined and clarified

    Server-side caching, or flash storage installed in the server itself, is deployed to accelerate application performance. Placing the flash as close to the application as possible reduces latency and improves performance.

    Over the past couple of years, there has been a lot of development in this area, and today, there are a number of ways that you can insert flash storage into a server. For example, you can use SATA form factor SSDs that install in place of traditional hard disk drives. Or you can use flash storage that connects directly to the PCIe bus. An emerging option is to attach flash storage directly to the server's memory channel via dual in-line memory module (DIMM) slots. Each, of course, comes with strengths and weaknesses.

    There are also a variety of standards emerging for server-side caching that are important to understand when selecting a product.

    This Drill Down on server-side flash will compare and contrast the variety of ways that you can deploy the technology today to help readers better understand the pros and cons to each approach. It will also explain when server-side caching is a better (or worse) alternative to an all-flash or hybrid-flash storage array. There's so much going on in this space today that it can be hard to stay on top of it all. This Drill Down will help.

  • Flash storage caching, tiering or both? Consider the workload

    If you're using a flash-based storage system, you're familiar with caching and tiering to accelerate data. Storage tiering is used in hybrid flash storage systems to separate active and inactive data. Active data is kept on the flash tier, while inactive data is moved to a less-expensive storage tier. If the data becomes "hot" once again, it is moved back to the flash tier. Because data only lives on one tier at a time, tiered architectures need to have some kind of redundancy built into them.

    In caching, data is copied or mirrored from one tier to another, so active data is on multiple tiers at the same time. If the active data is no longer needed, the cache will just create flash space for new data sets to use.

    Vendors implement tiering technology in various ways. Some even have a "flash-first" approach that puts all data on flash before it is moved to a hard disk tier to become inactive. Users therefore have to be careful not to overprovision flash in these environments.

    The decision to use tiering or caching depends on a variety of factors, such as the number of applications that require access to high-performance storage resources, the I/O patterns of these applications and your budgetary constraints.

    Learn when to use each of these technologies in your own environment.
