Cisco polishes HALO, flashes enlarged HyperFlex

Cisco has announced two all-flash HyperFlex systems with an up to sixfold performance improvement. HyperFlex is Cisco's hyper-converged* infrastructure appliance (HCIA) offering, based on OEM'd Springpath HALO software, with Cisco's UCS server and Nexus networking components. These are, were, hybrid flash and disk systems. …

My understanding is this is much faster than other hyperconverged all flash systems. Pretty much like native AF systems like Nimble and Pure vs old-school arrays full of SSD

Re: performance

That doesn't align with the "up to six times faster" mentioned in the announcement which can be interpreted as a marketing best-case scenario and is a pretty modest jump. Native AFA systems provide a much bigger boost than "up to 6x" vs. hybrid under test suites designed to provide bragging rights vs. traditional arrays.

Re: performance

Even hybrid systems depend heavily on SSD caching. So, any given moment, app performance on a hybrid system is going to be on par with an all-flash system.

What all-flash delivers is consistent performance gains for all read/write patterns, even the ones that normally blow cache away (databases).

Re: performance

I'm sorry, but using the cheapest TLC NAND you can buy (PM863 drives) and a single eMLC NAND based log drive vs. something using a NVDIM for write ACK. hmmmmm I wonder which will be faster :)

10.000 RPM SSD anyone.

At least when I write this there is a rather awkward error in stating that the SSD is 10.000 RPM disks multiple times. I presume not a lot of storage people in Cisco to validate the information.
