SSD高COCA⁷⁵⁵⁹³BNC¹⁹⁶⁴⁰ 基本例句 n.地下排水¹⁰⁰ It is beginning a long, slow shift from spinning optical drives to high- capacity solid-state storage SSD. 在旋转的光盘驱动器向高容量的固态硬盘 SSD的转变中,Facebook已经开始了很长时间了。 ecocn The internal security apparatus includes the Ministry of Public Security MPS and the State Security Department SSD. 内部安全保卫机构,包括公共安全部 MPS和国家安全部 SSD。 yeeyan The storage within an SSD can be written a finite number of times depending on the technology; therefore, it's important to be as efficient as possible when writing data. SSD内存储的编写次数是有限的取决于技术;因此,在编写数据时要尽可能的有效是非常重要的。 ibm The SSD technology has been around for a couple of decades already in the form of memory sticks, thumb drives, and so on. SSD技术已经出现20 年左右了,其表现形式有记忆棒、 U盘等。 ibm A single I/ O costs25 times less on an SSD than on an HDD. 单单一个 I/ O, HDD 耗时就比 SSD多25倍。 ibm But although SSD costs are declining every quarter, SSDs are still more expensive than HDDs. 但是,虽然 SSD的成本每个季度都在递减,但是 SSD仍然比 HDD昂贵。 ibm Chrome OS netbooks do not have HDDs but instead they use flash based memory solutions or solid state drives SSD for that. Chrome OS上网本并没有硬盘驱动器 HDD,而是采用了基于闪存的内存解决方案或是固态硬盘 SSD。 infoq Even though SSD writes are faster than traditional disk writes, disk write cache typically provides good disk write performance and levels the playing field between the two types. 即便 SSD写操作要快于传统的磁盘,但是磁盘写缓存通常提供良好的磁盘写性能,从而使这两种类型的磁盘可以实现相差无几的写性能。 ibm For example, if you have historical data in a table that is rarely accessed, you don't want it located on your more expensive SSD storage. 例如,如果您的表中保存的是很少访问的历史数据,那么肯定不希望它们占用昂贵的 SSD存储设备。 ibm For the anterior communicating artery aneurysm or post communicating artery aneurysm, MIP and SSD techniques should be used for further diagnosis. 对于前交通和后交通动脉瘤应进一步用 MIP、 SSD技术明确诊断。 iciba For this reason, Linux now supports the ability of the file system to communicate discarded blocks to the SSD as of kernel version2.6.29. 由于这个原因, Linux现在支持文件系统将丢弃块传递到 SSD的功能自内核版本2.6.29开始。 ibm He believes SSD is a great technology to replace hard disks in very high IOPS workloads, or when data cannot go to disk and must be held by main- memory RAM caches. 他认为,对于 IOPS非常高的工作,或者在数据不能写入磁盘,必须缓存在内存 RAM里面的情况下, SSD是一项替换硬盘的伟大技术。 infoq If none of the files that share the index specifies SSD, then the index will have a media preference of ANY. 如果这些共享索引的文件都没有指定 SSD,那么索引的媒介首选项为 ANY。 ibm Media preference can be specified for an index or keyed file to request that the underlying index object be allocated on SSD storage. 媒介首选项可以针对索引或键控文件指定,请求将底层索引对象分配到 SSD存储设备。 ibm Media preference can also be specified on a table or physical file to request that data itself should be allocated on SSD storage. 也可以对表或物理文件指定媒介首选项,请求将数据本身分配到 SSD存储设备。 ibm Note that if you specify the SSD attribute when you create the sharing index, the index will be moved to SSD at that time. 注意,如果在创建共享索引时指定 SSD属性,索引将在此时移动到 SSD。 ibm Note that if the physical file is keyed perhaps because it has a Primary Key constraint, its index will also be moved on or off of SSD with these commands. 注意,如果物理文件使用了键控可能因为它有一个 Primary Key约束,其隐式索引也将通过这些命令被移动到 SSD或从中移出。 ibm One way to reduce this effect is by telling the SSD when a block is no longer valid perhaps because of a file deletion. 减少这种影响的一种方式是告知 SSD一个块何时不再有效有可能是因为文件删除。 ibm Since main- memory is power-intensive and still expensive relative to hard disk ahd SSD, adopting SSD for such workloads makes a lot of sense. 由于内存是有限的,而且相对于硬盘和 SSD仍然昂贵,应用 SSD处理这样的工作是有意义的。 infoq Solid State Disk SSD support was added to IBM i in mid-2009 on releases V5R4 and IBM i6.1. 固态硬盘 SSD支持在2009 年中期发布 V5R4和 IBM i6.1 时被添加到 IBM i。 ibm The following SELECT statement will return any SQL tables or physical files that have some allocation on SSD in schema library MJATST. 下面的 SELECT语句将返回 MJATST模式库中在 SSD上有一些分配的任意 SQL表或物理文件。 ibm This ability allows the SSD to remove these blocks from wear- leveling processes and helps to increase the endurance of the drive. 此功能允许 SSD从耗损均衡进程删除这些块,并有助于增加驱动器的耐力。 ibm This notion is independent of SSD implementations and is more a reexamination of why REORGs are performed in the first place. 这个概念与 SSD实现无关,而是重新审视为什么要首先执行 REORG。 ibm When the SSD receives this new command, it can add the blocks defined to its free list and no longer worry about moving them around as part of wear-leveling. 当 SSD收到这个新命令后,它就可以将所定义的那些块添加到其释放列表,不会再担心这些块再成为损耗的一部分。 ibm When a block is freed in the SSD, it is no longer a target of wear-leveling and therefore can minimize the overall wear on the device. 当某个块从此 SSD释放后,它就不再是被耗损的对象了,进而能将此设备的总体耗损降至最低。 ibm When data appears to be physically adjacent in DB2 that is, consecutive pages in the table space, it is very unlikely to be in consecutive cells on the SSD. 当 DB2中的数据物理上邻接即表空间的连续页时,很可能在 SSD上是连续的单元。 ibm When multiple files share an index, if the media preference of any of those sharing files specifies SSD, then the index will have a media preference of SSD. 当多个文件共享一个索引时,如果这些共享文件的其中任何一个的媒介首选项指定了 SSD,那么该索引将有一个 SSD媒介首选项。 ibm Whether total or partial replacement for hard disk storage, SSD technology is a good tool in the datacenter operations arsenal. 无论是全部或部分更换硬盘存储, SSD技术都是数据中心运营工具箱中的优秀工具之一。 infoq You have an index that is associated with a Unique or Foreign Key constraint that is heavily used in queries that you want to put on SSD. 您有一个索引与 Unique或 Foreign Key约束关联并且该索引被大量的查询所使用,您希望将这个索引放入 SSD。 ibm |
