Storage network trend

一些趨勢觀察報告如下。

• IDC projection: 3x growtg in FC+NAS×iSCSI storage.
• IP storage vs Fibre Channel ('95~) storage.
• Gen5 16Gbps vs Gen6 32Gbps
• SSD/Flash requires faster networking:IOPS vs throughput
• Flash drive speed may be 10,000 times faster than 7200rpm!
• Monitoring and Alerting Policy Suite (MAPS) for network packets. ~ intuitive reporting ex. CRC errors.
• Loop is still the common issue for IP Network! => Brocade VDX could auto detect & correct config.
• Pure Storage: warranty peroid + volume capacity, as simple pricing.
• Introducing forever flash: controller (firmware) upgrade every 3 yrs. All Flash, everywhere.
• ex. Netflix has 1.5 factor gzip compression, and higher IOPS of PB scale data.
