Our environment consisted of ECKD devices allocated as 3390 model 27 devices.
我们的环境由ECKD设备组成，它们是27个3390型号的设备。
We used ECKD devices because they were readily available whereas an FCP SCSI environment was not.
之所以使用ECKD设备，是因为它们可以立即使用，而FCPSCSI环境则不能。
For the Lotus Domino workload, we ended up with about 20 TB of DASD attached to this one Linux kernel, defined as extended count key data (ECKD) devices.
对于LotusDomino工作负载，根据extendedcountkeydata (ECKD)设备的定义，我们最终有大约20TB的DASD连接到这一个Linux内核。
Eventually, we determined that the I/O issue was caused by the way the ECKD volumes were being supported in Linux and how requests were being queued at the logical device level.
最终，我们确定，I/O问题是由Linux支持ECKD卷的方式和逻辑设备级别上请求的排队方式引起的。
