The present invention concerns a twist drill comprising a shank and a cutting portion which is defined by the axial length of the chip flutes and which is at least partially coated. To provide a twist drill having the aforementioned features and a process for the production thereof, which on the one hand have very good properties in terms of service life and chip formation or chip transport, but which on the other hand are also highly suited for reconditioning including coating, in accordance with the invention it is proposed that the cutting portion has substantially over its useable length a first coating, wherein there is provided a second coating which is different from the first coating only in the region of the tip of the drill and which extends over an axial length which corresponds at a maximum to twice the nominal diameter of the drill.

An apparatus and method for sharing a boot volume among server blades. The shared boot volume may be a single drive or a RAID volume. The shared boot volume is first partitioned into boot slices. Next, individual boot slices of the shared boot volume are correlated with individual server blades, which share the shared boot volume. When a boot slice is correlated with a server blade, the boot slice is presented to the server blade, and the server blade sees the boot slice and only the boot slice, and owns the boot slice. This correlation is transparent to the OS or applications on a given server blade, because the I/O controller masks all boot slices but the one owned by that server blade. As far as OS and applications are concerned, the server blade just has a single boot slice as a dedicated local drive.

摘要:
A casket comprises a casket shell, a casket lid close able upon the shell and deployable structure, operably associated with either the shell or the lid, and integrally formed therewith, which, when deployed, defines a memorial surface adapted to have placed thereon items of memorialization for display. The deployable structure is so configured and arranged such that the items of memorialization must be removed therefrom when the structure is not deployed. In one aspect, the deployable structure can be operably associated with said shell. In another aspect, the deployable structure can be operably associated with the lid.
