Storage Class Memory is a technology that places memory and storage on what looks like a standard DIMM board. The DIMM is installed in the memory channel similar to a DRAM DIMM. Supporting storage in the memory channel is challenging…
Briefing Note: Diablo Delivers Flash As Memory Since its introduction to the enterprise, flash has been viewed as an expensive but fast alternative to the hard disk drive, but not as inexpensive as RAM. Flash implementation options like PCIe SSDs…
Software defined storage solutions like vSAN are gaining increased attention. But vSAN systems can only support one flash device. The challenge is one flash device may not be enough to handle all the I/O throughput from multiple applications. In this…
The removal of latency is a critical part to delivering more fully on the flash performance promise. No matter how fast the flash technology becomes, the latency of its connection to the CPU is a key stumbling block in achieving…
Server-side Flash and SSD has delivered significant storage I/O performance benefits to physical and virtualized host environments. While SSD provides many benefits, it is not without its drawbacks. By adding another device into a PCIe slot, for example, SSD resources…
One of the key attributes of flash storage is its ability to remove storage I/O latency. The memory based storage technology can respond instantly to requests for data. However, flash’s zero latent nature exposes latency in other parts of the…
One of the more interesting technologies at the Flash Memory Summit this year was presented by SMART Storage and Diablo Technologies. They’ve taken server-side flash implementation to a new level with SMART Storage’s ULLtraDIMM, a flash storage device that puts…
As Storage Switzerland discussed in two articles recently flash based appliances are particularly vulnerable to power failures. This vulnerability is related to the way these appliances use DRAM to buffer writes and to store meta data tables. DRAM is volatile,…
As the storage medium for main memory DRAM is where the processing work gets done in application servers. It’s generally the fastest mass produced data storage area available and can support the nearly unlimited cycle of writes and overwrites that…
