SoftLayer对象存储API：创建250GB/500GB块存储失败。 20GB或1000GB都OK

Question

我正在部署CloudFoundry并在内部调用SoftLayer API来创建250GB iSCSI磁盘，但会导致如下错误。
以类似的方法，创建500GB磁盘出错，但20GB或1000GB创建成功。

是SoftLayer API问题还是我的环境改变了一些价目表？

Answer 1

简短的回答是，你需要使用1000，而不是250或500的这个请求，如果你想继续使用相同的筛选器：

Request: 
GET /rest/v3/SoftLayer_Product_Package/222/getItemPrices.json?objectFilter={"itemPrices":{"attributes":{"value":{"operation":250}},"categories":{"categoryCode":{"operation":"performance_storage_iops"}}}}&objectMask=filteredMask[id;locationGroupId;item.id;item.keyName;item.units;item.description;item.capacity] HTTP/1.1 
Host: api.softlayer.com 

长的答复是，你将无法使用softlayer的过滤器来获取这些值，并且您将需要使用自己的代码来过滤这些值，这是因为IOPS价格具有存储容量的限制，例如

rest/v3/SoftLayer_Product_Package/222/getItemPrices.json?objectMask=filteredMask[attributes,capacityRestrictionMaximum,capacityRestrictionMinimum,id,locationGroupId,item[id,keyName,units,description,capacity]] 
{ 
     "id": 41522, 
     "locationGroupId": null, 
     "attributes": [ 
      { 
       "id": 11860, 
       "itemPriceAttributeTypeId": 21, 
       "itemPriceId": 41522, 
       "value": "100", 
       "itemPriceAttributeType": { 
        "id": 21, 
        "keyname": "CAPACITY_RESTRICTION_MIN" 
       } 
      }, 
      { 
       "id": 11862, 
       "itemPriceAttributeTypeId": 22, 
       "itemPriceId": 41522, 
       "value": "1000", 
       "itemPriceAttributeType": { 
        "id": 22, 
        "keyname": "CAPACITY_RESTRICTION_MAX" 
       } 
      }, 
      { 
       "id": 11864, 
       "itemPriceAttributeTypeId": 24, 
       "itemPriceId": 41522, 
       "value": "STORAGE_SPACE" 
      } 
     ], 

在上述结果可以看到瓦莱斯CAPACITY_RESTRICTION_MAX和

CAPACITY_RESTRICTION_MIN这些价值观意味着价格的有效期为100个GB的存储，以1000个GBS，所以这个价格还是不错的250个GB的储存和500GB。您正在使用的过滤器正在过滤这些值，因此您必须更改过滤器以验证您的存储（本例中为250GB）是否在此范围的值之间，但不能使用Softlayer的过滤器完成，因为值过滤器是字符串，而不是一个整数如：

"value": "100" 

所以，你需要分析该值整数，然后验证它是否为范围（使用Softlayer's过滤器这是不可能的）。

当前过滤器为其他值工作的原因是因为CAPACITY_RESTRICTION_MAX和CAPACITY_RESTRICTION_MIN具有相同的值，例如

"id": 40792, 
     "locationGroupId": null, 
     "attributes": [ 
      { 
       "id": 9670, 
       "itemPriceAttributeTypeId": 21, 
       "itemPriceId": 40792, 
       "value": "20", 
       "itemPriceAttributeType": { 
        "id": 21, 
        "keyname": "CAPACITY_RESTRICTION_MIN" 
       } 
      }, 
      { 
       "id": 9672, 
       "itemPriceAttributeTypeId": 22, 
       "itemPriceId": 40792, 
       "value": "20", 
       "itemPriceAttributeType": { 
        "id": 22, 
        "keyname": "CAPACITY_RESTRICTION_MAX" 
       } 
      }, 
      { 
       "id": 9674, 
       "itemPriceAttributeTypeId": 24, 
       "itemPriceId": 40792, 
       "value": "STORAGE_SPACE" 
      } 
     ],
