Hu Yoshida goes beyond Virtualization



...and he elaborate how "Hitachi Universal Storage Platform V" will take us all to the "All Virtualized Infrastructure".

Dynamic Provisioning which enables the ability to virtualize capacity within virtual volumes. This enables IT to eliminate the waste of allocated but unused space. While virtual volumes enabled non disruptive data movement for migration, replications, and tiered storage, it did not address the problem of allocating more space than is actually used in the primary volume as well as in all the replicas of that volume. Some storage systems can virtualize capacity with thin provisioning, but they don’t offer virtualization of the volume for non-disruptive data mobility. Hitachi’s Dynamic provisioning provides all this and much more. With Dynamic provisioning Hitachi also provides wide striping across large storage pools, where hundreds of disk drives can be employed to service an I/O request and provide self tuning.


Check out his blog. It is a sales pitch so if you are a Hitachi client, you'd be interested in it.

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.

OS Virtualization comparison: Parallels' Virtuozzo vs the rest

Virtuozzo's main differentiators versus hypervisors center on overhead, virtualization flexibility, administration and cost. Virtuozzo requires significantly less overhead than hypervisor solutions, generally in the range of 1% to 5% compared with 7% to 25% for most hypervisors, leaving more of the system available to run user workloads. Customers can also virtualize a wider range of applications using Virtuozzo, including transactional databases, which often suffer from performance problems when used with hypervisors. On the administration side, customers need to manage, maintain and secure just a single OS instance, while the hypervisor model requires customers to manage many OS instances. Of course, the hypervisor vendors have worked hard to automate much of this process, but it still requires more effort to manage and maintain multiple operating systems than a single instance. Finally, OS virtualization with Virtuozzo has a lower list price than the leading hypervisor for comme...
