6405E為目前最強的PCIe 1x RAID HBA...
6E系列是6系列的刪減版...
主要是較少的Cache buffer, 不提供Parity層級的RAID mode以及沒有BBU支援..
其餘基本上高級的RAID功能都沒刪掉..
例如Copyback機制, IPM節能, DHSP/PHSP支持,
另外支持高級的混合式RAID模式-Hybrid SSD/HDD RAID 1&10...
當然不管是6E或著6系列全部都不支持最強安全性的MPIO機制...
價格遠比6系列低..
可以看做是SSD專用加速卡...

How is the Adaptec Series 6E different from the Adaptec Series 6?

Adaptec Series 6E controllers deliver the same 6Gb/s performance of our Series 6 controllers, but are optimized for platforms where a Series 6 controller would not fit in from a price, form factor or host connectivity standpoint. The 6405E offers maximum connectivity through a x1 PCI Express 2.0 interface that fits into any industrial PC, workstation class or entry server class motherboard, while the 6805E has a x4PCI Express 2.0 interface for application that require more bandwidth. As an entry level card, Series 6E offers less cache memory, RAID

How is the Adaptec Series 6E different from the Adaptec Series 2?

Both are optimized for entry-level systems. The Series 6E offer 6Gb/s throughput at each port while the Series 2 offer 3Gb/s throughput. In addition to that, Series 6E fits into platforms with that are equipped with a x1 or x4 PCI Express slot while Series 2 requires at minimum a x8 PCI connector on the motherboard

What RAID levels do the Series 6E products support?

The Series 6 RAID controller family supports standard RAID levels 0, 1, 1E, 10, and JBOD. It also supports Copyback Hot Spare, which allows the user to specify a fixed physical location for the hot spare for improved manageability.

6805早出了吧，４Ｇ的固态缓存爽

是6E系列..
不是6系列...
4GB是ZMCP...
對性能不會有任何幫助...

pmcc的ａｒｍ本来新能就一般，想性能就搞ａｒｅｃａ　１８８０好了

一張只支持RAID0、1、10且有128MB Cache的Hardware HBA

這關鍵取決於RAID stack..
不是光拚硬件就可以..
否則PMC不會發傻去買Adaptec...
6/6E系列能見度不高...

回复 per1-q1222 的帖子

PMC买adaptec是因为adaptec的成熟产品线和产品的开发能力，PMC自身没有完整的产品，是chip生产商。
