Rice University's PhD candidate writes thesis on "Storage virtualization and performance"

He plans to defend it soon. Its actually called : Performance Virtualization and QoS in Shared Storage Systems


This dissertation targets the problem of performance virtualization in shared storage systems. This is motivated by growing trends towards storage consolidation. The goal is to provide performance guarantees to an application irrespective of the behavior of other concurrent workloads. In doing so, we propose QoS scheduling mechanisms for both centrally shared storage systems and distributed storage systems such as FAB and IceCube. QoS and efficiency are two strongly opposing forces when it comes to sharing of I/O devices, and it is a challenge to achieve both simultaneously.

Security: VMware Workstation 6 vulnerability

vulnerable software: VMware Workstation 6.0 for Windows, possible some other VMware products as well type of vulnerability: DoS, potential privilege escalation I found a vulnerability in VMware Workstation 6.0 which allows an unprivileged user in the host OS to crash the system and potentially run arbitrary code with kernel privileges. The issue is in the vmstor-60 driver, which is supposed to mount VMware images within the host OS. When sending the IOCTL code FsSetVoleInformation with subcode FsSetFileInformation with a large buffer and underreporting its size to at max 1024 bytes, it will underrun and potentially execute arbitrary code.

Whale Fall ----------------- Dress me up in my new threads clasp my greasy palms grease my hair I'm ready for the fall Watch at all the decadence watching the avalanche I'm slipping down losing my buoyancy What's become of us where have we come this far, this close close to the doors I hear them, sublimal chants I'm on the run I race through the human sea I am the king! I'm the slave to my own undoings I'm the jester in my courtyard We jest as we run We're strolling on that thin rope we grope as we rope we're true heros we're the survivors we're the scavengers we're the friends we're the lovers we're the unbred Soon awaiting the fall we're lurking on us we're osedaxing us we're soon going to be done we'll soon be arrested *osedax(bone devourer, newly discovered marine genus) feeds on a fallen(sunken) whale carcass(which is also called a whale fall).
