The disk performance and breeding property of storage.
After target device accesses storage system, the parameter of the storage performance for determining target storage device, i.e. target
The controller parameter of equipment and the disk performance of target storage device are stored, different interface polls can be passed through.For example, can be with
By the product type of system interface polls target storage device, pass through the software of system interface polls target storage device
Version passes through License interface polls mesh by the controller chassis cache size of CONTROLLER interface polls target storage device
Whether mark storage equipment supports the functions such as duplication, snapshot and dual-active, passes through solid-state in disk interface polls targeted memory controller
Hard disk (Solid State Drives, SSD) model and quantity, pass through hard disk (disk) interface polls target storage device
SAS disc-type and quantity.
After the controller parameter and disk parameter for obtaining target storage device, target can be calculated by above-mentioned parameter and deposited
Store up the storage performance of equipment.Specifically, the performance of target storage device can be embodied from least one of three kinds of parameters parameter:
IOPS, bandwidth and time delay.
The assessment algorithm of IOPS and time delay is introduced in detail below.
One, IOPS assessment algorithm
IOPS assessment algorithm under random small IO scene is based on RAID principle and Cache hits principle, comprehensively considers to write and punish
It penalizes and the factors such as caching (Cache) hit rate.Wherein, writing punishment is since RAID is realizes data protection, when data are written
It needs that check bit is written simultaneously, brings additional IO expense；Cache hit rate be due to repeated data read-write or prefetching algorithm,
Part read-write IO is hit in Cache, to reduce the IO of lower wall, the ratio of the total IO of IO Zhan hit in Cache is
Cache hit rate.
Specifically, the total IOPS=disk single-deck IOPS × number of disks of disk, and IO amplification coefficient=reading ratio ×
(100%- read hit rate)+write ratio × (100%- writes hit rate) × writes penalty coefficient, then the IOPS of target storage device can
To be calculated by the following formula:
Wherein, writing choosing for penalty coefficient can determine according to the RAID level of target storage device support, such as in table 3
It is shown.
Table 3
| RAID level | Write penalty coefficient |
| RAID 0 | 1 |
| RAID 10 | 2 |
| RAID 5 | 4 |
| RAID 6 | 6 |
| RAID 3 | 4 |
| RAID 50 | 4 |
Two, time delay assessment algorithm
Time delay under random small IO scene can determine by the time delay of three parts IO, i.e., more lower walls read part IO when
Prolong, Cache read hit part IO time delay and write-back IO time delay weighted calculation obtain, in addition it is also contemplated that writing IO to reading
Influence COMPREHENSIVE CALCULATING of the time delay influence and I O size of IO to time delay.
For example, including Serial Attached SCSI (SAS) disk (Serial Attached SCSI, SAS), SATA in target storage device
(Serial ATA) hard disk and NLSAS disk.In target storage device multilayer disk lower wall read weighting time delay=reading ratio ×
(100%- reads hit rate) (solid-state hard disk SSD disk reads time delay × SSD disk pressure ratio+server hard disc SAS disk and reads time delay × SAS
Disk pressure ratio+NLSAS disk reads time delay × NLSAS disk pressure ratio) it writes to impact factor is read, read weighting time delay=reading ratio of hit
× read hit rate × reading hit rate time delay, write-back weights time delay=(100%- read ratio) write-back time delay, then average delay=
(multilayer disk lower wall reads weighting time delay+reading hit partial weighting time delay+write-back and weights time delay) I O size impact factor.
Wherein, it has been set forth below under several frequently seen scene, the selection side of each parameter in the formula of above-mentioned calculating average delay
Formula.
200GB/400GB/600GB SSD disk is read time delay value and is fixed are as follows: 0.75ms；
900GB/1.8TB/3.6TB SSD disk reads time delay value: only when SSD, time delay value is according to I O size, disk pressure
Than taking corresponding time delay referring to table 4；When more than SSD disk, time delay takes time delay when 80% pressure ratio.
Table 4
10K SAS disk reads time delay value: 12ms；
15K SAS disk reads time delay value: 10ms；
NL-SAS disk reads time delay value: 20ms；
Read hit time delay: 0.5ms；
Write-back time delay (including writing hit time delay): 1ms；
Write to reading impact factor: -0.6* reads ratio+1.6；
I O size impact factor: when I O size is 4K or 8K, I O size impact factor can take 1；When I O size is 16K
When, I O size impact factor can take 1.05；When I O size is 32K, I O size impact factor can take 1.2；Work as I O size
When for 64K, I O size impact factor can take 1.6.
The total IOPS of offer IOPS/ of SSD disk pressure ratio=SSD layers；
SSD disk pressure ratio+SAS disk pressure ratio+NLSAS disk pressure ratio=100%.
For example, target storage device uses the classification storage configuration of SSD and 10K SAS, need to assess in I O size is 16KB,
Than being 7:3, reading hit rate is the average delay in the case of 10% for read-write, and wherein SSD provides 20000IOPS altogether, and 10K SAS is total
Provide 5000IOPS, then:
Multilayer disk lower wall reads weighting time delay=reading ratio × (100%- reads hit rate) (SSD disk reading time delay * SSD disk pressure
Power ratio+SAS disk reads time delay × SAS disk pressure ratio) it writes to reading impact factor
=70% × (100%-10%) * (0.5 × 20000/25000+12 × 5000/25000) 1.3=2.49；
Read hit partial weighting time delay=reading ratio × reading hit rate × reading hit rate time delay=70%*10%*1=
0.07；
Write-back weights time delay=(100%- reads ratio) write-back time delay=(100%-70%) × 1=0.3；
Then, average delay=(multilayer disk lower wall reads weighting time delay+reading hit partial weighting time delay+write-back and weights time delay)
I O size impact factor=(2.49+0.07+0.3) 1.05=3ms.
320, according to the performance parameter of the target storage device, and the performance parameter and memory resource pool of storage equipment
The grade of service corresponding relationship, determine the target service class of memory resource pool belonging to the target storage device.
