摘要： A method for accessing data in a storage area network is provided. The method initiates with receiving a request for a list of targets on the storage area network. All the targets on the storage area network are exposed to the requestor and authentication requiring a password is requested from the requestor to grant access to the targets on the storage are network. Access to the targets is granted if the password is acceptable, and access to the targets is refused if the password is unacceptable.

摘要： An oscillator and method for generating a signal are provided. The oscillator comprises an electro-mechanical resonator and a reconfigurable oscillator driver. The reconfigurable oscillator driver starts the oscillator in single-ended mode to avoid latching and transitions the oscillator to differential mode in such a manner as to sustain oscillations therein. The reconfigurable oscillator driver comprises two back-to-back banks of inverters and an adjustable feedback resistor. In single-ended mode, one bank is disabled and the other bank is enabled. To transition to differential mode and improve the quality of the signal, the number of enabled inverters is equalized in both banks.

摘要： The disclosure generally relates to a PCIe switch that includes a selectively transparent bridge that selectively allows transactions to traverse between multiple PCIe domains without the encumbrance of each root complex entity requiring knowledge of the selectively transparent bridge. The bridge that enables the transactions is invisible to the root complex entity in a host and drive switch domain of the PCIe switch. No address translation of the transactions is required because the drive switch domain address map is a subset of the host switch domain address map. The bridge allows for extremely low latency transactions between host systems and storage drives because the bridge allows the storage drive to read the Direct Memory Access (DMA) Scatter-Gather List (SGL) directly from host memory. The bridge also allows I/O data reads and writes from the storage drive directly to the host memory without store and forward within a RAID controller's memory.
摘要翻译：本公开通常涉及PCIe交换机，其包括选择性地透明的桥，其选择性地允许事务在多个PCIe域之间穿越，而不需要知道选择性透明桥的每个根复杂实体的阻碍。启用交易的网桥对于PCIe交换机的主机和驱动器交换机域中的根复合实体是不可见的。由于驱动交换机域地址映射是主机交换机域地址映射的子集，所以不需要交易的地址转换。桥接器允许在主机系统和存储驱动器之间进行极低延迟的交易，因为该桥接器允许存储驱动器直接从主机存储器读取直接存储器访问（DMA）分散收集列表（SGL）。桥接器还允许从存储驱动器将I / O数据读取和写入直接存储到主机存储器，而无需在RAID控制器的存储器内存储和转发。

摘要： A number of methods and clock generator units are disclosed to produce low Phase Noise clocks for use in Radio Frequency systems. The methods and clock generator units all use two reference clocks: a frequency-accurate reference that has comparatively high Phase Noise, and a frequency-inaccurate reference such as that from a BAW or MEMS clock source that has comparatively low Phase Noise. By combining multiple Phase-Locked Loops and a mixer, it is possible to produce flexible output frequencies whose frequency accuracy is derived from the first reference clock but whose Phase Noise level is derived from the second reference clock, all in a readily-integrated and relatively low-cost system.
