New PCI-Express Internal Fabric

Performance– PCI-E fabric increases data throughput, especially for sequential workloads

Availability – PCI-E fabric reduces the impact of hardware failures

Scalability– Scale internal bandwidth by adding additional data links or "lanes”

Flexibility and upgradability– PCI fabric enables single DS8700 model with flexibility to fit customer

requirements– Concurrent upgradability of all components from small to large

configurations

Enabling future growth

Lower acquisition costs by enabling non-disruptive upgrades from base 2-way model to full-blown 4-way model!

Delivering Higher Value with Solid-State Technology

It’s not enough to enable your disk system to run faster with SSDs

–An application's performance depends on the total IT infrastructure

Clients are asking for help to exploit SSDs by understanding–Impact across servers, storage, and middleware–Comprehensive data analysis tools–Intelligent data migration capabilities–Relevant storage management tools

固态盘技术

缺点 磨损问题

– 坏扇区可能蔓延

容量– 相对于普通硬盘目前容量仍旧偏小

成本– 相对于普通硬盘目前价格相对较高

优点

可靠性更高– 无需机械移动

更加节能和环保– 用电量更少– 散热更少

更高性能– 相对于 15000 转的普通硬盘,可以

达到高至 100 倍的吞吐量,以及低至 10 倍的响应时间

– 单位 IOPS 的价格大大低于普通硬盘
