the controller says hey let’s make a copy of that and put it in the SSD cache. Say this same piece of data is repeatedly read/requested, over and over. If not, then it checks the SSD cache to see if it’s there, and if it isn’t goes to the HDD for the read and sends it up. A request for a certain block of data comes in and the controller checks it’s onboard DDR cache to see if it is there. That describes the write side of the house.įor the read, it’s the same thing but slightly different. As the writes to the HDD complete, the cache likely flushes itself. The whole time these two caches are getting filled up, the HDD array is writing as quickly as possible to the HDDs, playing catch-up to the solid state based caches (the onboard DDR and SSD caches). If the onboard controller cache fills up because the file is larger than the cache, it will direct the writes to the SSD based cache. So once you have it setup, writes intended to go to the HDD array will first be written to the DDR cache on the controller, which is trying to quickly write it to the HDD.
The CacheCade feature allows for a regular SSD connected to the raid card normally to be identified as the read/write cache for slower, but likely higher capacity and cheaper per Terabyte, HDD based arrays. For residents of other cities it is possible to exchange, service and return by sending to the "New Mail" in the package must attach a scan copy of the warranty card.So basically it’s a feature that gets enabled through the card when this little key is attached to the raid controller. You should have a purchase check and an ID with you. Representative offices of manufacturers in Ukraine assume responsibility for warranty service.Īt the end of the warranty period, experts at the service center are ready to help with the repair and maintenance of any equipment.Īccording to the law, the buyer has the right to return the product without giving a reason within 14 days, but in this case it should not be used, all documents and packaging to it are saved.
If the warranty card does not come bundled with instructions, the store issues it. They are denied warranty service only if the goods were damaged or a breakdown occurred due to the user's fault. The warranty period depends directly on the manufacturer and is valid for the entire time.
Warranty service is provided by the manufacturer, its period is specified in the coupon and on the website.
