Web11 jun. 2013 · That’s why VDI guidelines state that for light, medium and heavy users, the IOs needed are 4, 8 and 12 respectively, and an additional 25% for peak logon times. Sizing for 1000 users at 80% light and 20% heavy would require the storage infrastructure to deliver: 1000 * (80% * 4 + 20% * 12) * 125% = 7000 IOPS at 15% reads and 85% writes. WebHiểu đơn giản, IOPS là số thao tác đọc ghi trong một giây của ổ cứng. Ví dụ: 4k được 50000 IOPS nghĩa là tốc độ read/write = 50000*4k=200000K/s~ 200MB/s Tham số này thể hiện: SSD này sao chép được 200 MB/s các file nhỏ như 4k trong thời gian 1 giây.
