Red Hat adopts KVM: what happens to Xen now? - I work in a VMware ESX shop right now (other than all those Solaris Zones and FreeBSD Jails and OpenVZ VEs, that is) - no Xen or KVM. However, given the serious pain in the butt that timekeeping is in Linux guests on ESX, [...]
Chuck’s got another, uh, thought-provoking blog post up, More Examples Of Why Server Vendors Just Don’t Get Storage, surely intended to ruffle a few feathers. And he does raise some really good points: Most server vendors need more of an SSD strategy than just making a flash drive an option (it’s how you use [...]
HP servers to get flash memory I/O boost - It looks like SSDs will become a common option on server hardware; the real issue will be how to adapt your operating system/file system/application to use them optimally.
BlueArc’s Titanic benchmark holed - A storage vendor using a non-real-world configuration to optimize benchmark results? Really? [...]
Cloud Computing: Is the Cloud There Yet? - A Brief History: A mostly negative look at the prospects for cloud computing. Although the arguments it makes are fairly reasonable, the article appears to presume that cloud computing is an all-or-nothing proposal, not a tool for only some tasks. Also odd - “Many routine [...]
There’s been a lot of noise from the storage industry about flash recently - in particular, noise from EMC and Sun, both of whom recently announced storage products using flash, EMC in January and Sun earlier this month. Below are my thoughts on what EMC and Sun are doing, as well as what NetApp [...]
Adam Leventhal’s Weblog: Flash, Hybrid Pools, and Future Storage - Excerpts from a forthcoming ACM article on hybrid (flash-disk) storage pools, including: “Flash should be viewed not as a replacement for existing storage, but rather as a means to enhance it. [...] By combining the use of flash as an intent-log to reduce write latency [...]
Jonathan’s Blog: Anything But a Flash in the Pan - Jonathan Schwartz on Sun’s soon-to-be-released (late this year) flash drives. Quote: “ZFS will transparently incorporate Flash into the storage hierarchy of a running system, using the microprocessor cache for the most performance sensitive tasks, DRAM for the next, then Flash, then disk (then ultimately [...]
