Condition to Move Data into SSD Cache
• Read Data Size ≤ 16KB Data will be copied to SSD Cache pool directly even if it has been
only read once
• Read Data size > 16KB If this data has been read a couple of times, firmware will
recognize it as hot data and will then be classified as frequently accessed hot data and cached in the SSD Cache pool

The Benefits of Hybrid Storage with SSD Cache
• Read performance enhancement
• Intelligently moves a copy of the frequently accessed data from HDDs to SSD cache pool
• Simple and intuitive GUI design

Storageflex Hybrid Solution with SSD CacheAdvantage
• Preferred Application Workloads Small-block random read I/O application
Data-rehits: High access frequency to the same data
System where current performance is limited by HDD
19
Best Practice and Application Scenario of SSD Cache
SSD Cache Must Knows
• There is no benchmark tool to simulate hot/cold data access ratio and evaluate the overall performance
• The storage capacity of the system’s SSD Cache determines the amount of hot data that can be stored to take advantage of SSD benefits

What type of Data Blocks will be Promoted?
• All data enters the storage pool through the highest tier
• Hot data prioritization is weighed by data residence age and access frequency during a period of times (Based on user-defined schedule)
• Newly written and heavily accessed data is marked as hot data
• Hot data has higher priority for residing in higher performance tiers when migrating.

FAQ (1/2)
• For All-Flash Storage, HA3969 does not have de-duplication and compression features. Compared with other competitors, is it a weakness? The application of SSD of technology translates to great performance boosts but will also
require more CPUs/ PCI-e cards to compliment the extra workload. Hence, additional costs will incur
The goal of de-duplication and compression is to improve storage utilization because dollar-per-Gigabyte of SSD was quite high several years ago, but as SSD technologies have matured in recent years (capacity increase), the price-margin have also narrowed (cost/GB)
De-duplication and compression features help to improve SSD lifespan. Storageflex counteracts this by using qualified high-endurance SSDs which incorporates intelligent controllers to appropriately allocate data-store location.

FAQ (2/2)
• SSD Cache and Tiering both are suitable for OLTP workload, but which is the better? It depends on the user’s access behavior. In most of cases, the
read/write ratio can range from 80/20 to 50/50. For users that have a read/ write ratio of 80/20, meaning lots of data are frequently repeatedly read, the SSD Cache solution is one of the cost-effective choices. On the other hand, by using more SSDs in Tiering, it will improve read/write performance not only for 80/20 read-write ratio workloads but also for 50/50 workloads and others
