更改虚拟磁盘的分段大小, 启用动态高速缓存预读取。

4在 Select cache properties （选择高速缓存属性）区域中，您可以选择：

•Enable read caching （启用读取高速缓存）—启用读取高速缓存。

•Enable dynamic cache read prefetch （启用动态高速缓存预读取）

— 启用动态高速缓存预读取。

•Enable write caching （启用写入高速缓存）—启用写入高速缓存。

• Enable write caching with mirroring （启用带镜像功能的写入高速缓存）—跨两个具有相同高速缓存大小的冗余 RAID 控制器模块镜像高速缓存的数据。

• Enable write caching without batteries （启用无电池写入高速缓存）—允许写入高速缓存继续（即使 RAID 控制器模块电池已完全放电、未充满电或不存在）。

小心：可能丢失数据 –选择 Enable write caching without batteries （启用无电池写入高速缓存）选项可继续执行写入高速缓存操作（即使电池已完全放电或未充满电）。通常，写入高速缓存将由 RAID 控制器模块临时关闭，直到电池充满电。如果您选择此选项且未保护通用电源设备，则可能会丢失数据。此外，如果您没有 RAID 控制器模块电池并选择 Enable write caching without batteries （启用无电池写入高速缓存）选项，您可能会丢失数据。

注：启用 Optional RAID controller module batteries （可选的 RAID 控制器模块电池）时，不会显示 Enable write caching （启用写入高速缓存）。 Enable write caching without batteries （启用无电池写入高速缓存）仍然可用，但默认情况下不会选中。

注：禁用 Enable write caching （启用写入高速缓存）复选框后，高速缓存会自动刷新。

更改虚拟磁盘的分段大小

您可以更改选定虚拟磁盘上的分段大小。在此操作期间， I/O 性能会受到影响，但数据仍然可用。

继续更改分段大小的原则：

•此操作一旦启动便无法取消。

•除非磁盘组处于 Optimal （最佳）状态，否则请勿启动此操作。

MD3620F, MD3600f specifications

Dell's MD3620F and MD3600F storage arrays are designed for businesses seeking dependable, high-performance storage solutions tailored to meet the demands of modern data management. These models offer a blend of scalability, efficiency, and advanced features, making them well-suited for a range of applications, from virtual environments to critical database operations.

One of the primary features of the MD3620F and MD3600F is their support for a hybrid storage architecture. This approach allows organizations to combine flash storage with traditional hard disk drives (HDDs) to optimize performance and cost. The MD3620F focuses heavily on all-flash configurations, delivering exceptional speed and lower latency, ideal for I/O-intensive workloads.

Scalability is another hallmark of these storage solutions. The MD3600F allows users to scale up to 120 drives, providing robust capacity to meet growing data needs. The MD3620F is engineered for environments where data availability and speed are paramount, with support for high IOPS (Input/Output Operations Per Second) and consistent performance under stress.

In terms of data management, both systems integrate with Dell’s proprietary software, which enhances operational efficiency through features like automated tiering. This technology optimizes data placement between different storage types based on access frequency, ensuring that hot data is readily available while reducing costs associated with less critical data.

Reliability is crucial for businesses that depend on their storage systems. The MD3620F and MD3600F come equipped with advanced data protection mechanisms, such as RAID support, which safeguards against data loss, and snapshot capabilities that provide point-in-time copies of data. Moreover, these solutions include hot-swappable components, ensuring minimal downtime for maintenance and repairs.

Connectivity is also a strong suit of these storage arrays. They support multiple connectivity options, including SAS and iSCSI, allowing for flexible integration into existing IT infrastructures. This adaptability enhances their appeal to a wide range of enterprise environments.

In summary, the Dell MD3620F and MD3600F stand out as robust storage solutions with a combination of hybrid and all-flash configurations, scalability, advanced data management tools, and enhanced reliability features. These characteristics make them ideal for organizations looking to enhance their data storage capabilities while maintaining high performance and efficiency.
