From the ComputerWeekly article: Smart and Diablo launch Ulltra DIMM memory channel storage
Full article found here: Smart and Diablo launch ULLtra DIMM memory channel storage
I wanted to comment on one of the last paragraphs in the article:
ULLtra DIMM does, however, suffer the shortcomings of PCIe flash in that it is isolated without any method of sharing or protecting data between separate instances of memory channel storage in different servers. Spanjer said redundancy would need to be built in at the level of the application.
The point I want to make is, DataCore’s SANsymphony-V (SSV) is that application. You can not only protect data by providing redundancy across multiple flash modules within the server (whether it be DIMM-flash, SSD, or PCIe SSD), but you can also protect data through synchronous mirroring across the servers.
When SSV is installed on a server, it has access to all block storage devices connected to that server. SSV gives you the option to RAID-1 (mirror) those local block devices thereby protecting the data against failure (this is referred to as a Storage Pool Disk Mirror).
Additionally, SSV can provide the same level of protection across servers through synchronous mirroring. Of course SSV can provide both protection mechanisms simultaneously for maximum protection against failure.
I have only just scratched the surface of what SSV can do to safeguard your data. For more information about SANsymphony-V, please visit DataCore Software.
