What provide above-described embodiment below in conjunction with Fig. 4 to Fig. 7 and preferred embodiment is described in more details based on the resource allocation methods of automatically simplifying configuration and describes.
In following preferred embodiment, the granularity of automatically simplifying configuration is variable, system can have a minimum particle size given tacit consent to, create automatically simplify configuration time, user can configure a maximum granularity for simplifying pond (can comprise multiple simplification volume) or simplification volume.
Distributing according to initial particle size, when all blocks are all assigned, reducing the granularity of distributing.Volume sets up mapping table with new granularity, and it is new granularity that resource pool changes partition size.Fig. 4 is the schematic diagram of automatically simplifying configuration change of granularity according to the preferred embodiment of the invention, and as shown in Figure 4, the minimum granularity of system default is 16KB, and user configured maximum particle size is 1GB.During original state, what system automatically simplified configuration according to the granularity of 1GB writes front distribution, and records according to minimum granularity the bitmap that I/O write.Now the performance of I/O is higher, close to the performance of non-simplification volume.Along with the consumption to space, when the granularity according to 1GB, simplify allocation of space in resource pool complete time, start the change starting partition size.Such as partition size is changed to 64MB, now can discharges the space that some 64MB are unit.New I/O distributes in units of 64MB.When the free space of 64MB distributes, restart the change of partition size, distribute in units of 4MB.Along with business is to the consumption of free space, constantly reduce partition size, until the remaining space of the minimum partition size of the system that reaches or resource pool reaches alarming threshold.
The remaining space of system is the bitmap according to writing I/O record, carrys out statistical space consumption with minimum granularity, and when space consuming reaches the thresholding of specifying to user's alarm, prompting user adds new dish.Once space consuming reaches alarming threshold, prove according to current granularity be space utilization rate and I/O efficiency comprehensive after more efficient granularity configuration, even if therefore to after storage pool dilatation, also need not carry out the adjustment that granularity becomes large again.
In the preferred embodiment, when I/O arrives simplification volume, the address for unallocated space carries out writing front distribution.If by current granularity, the space of resource pool is assigned, then enable the flow process of mapping granule change.Changed by mapping granule and carry out Free up Memory.Fig. 5 is that simplification volume writes the processing flow chart of I/O according to the preferred embodiment of the invention, and as shown in Figure 5, this flow process comprises the following steps:
Step S502, I/O arrive simplification volume;
By query mappings table, step S504, judges whether the space that I/O is corresponding has distributed physical resource (physical space);
Step S506, if the address on I/O correspondence volume is assigned with physical space, then issues I/O on the physical address of correspondence, performs step;
Step S508, if the unallocated physical space in address on I/O correspondence volume, then carries out writing front distribution, judges whether resource pool exists idling-resource block (free space), if having, perform step S510, otherwise, perform step S522;
Step S510, if the space that resource pool is also available free, distributes idle block to volume according to current partition size;
Step S512, according to the minimum particle size of configuration, record volume is write the bitmap of I/O;
Step S514, if the space of resource pool distributes, judges whether remaining space is zero;
Step S516, if zero, enable the flow process of mapping granule change, being changed by mapping granule and carry out Free up Memory, after Free up Memory, is current I/O allocation block according to new granularity;
Step S518, if not zero, whether the consumption of the resource pool calculated according to minimum particle size reaches thresholding, if so, then performs step S520, otherwise, perform step S524;
Step S520, simplifies pond generation space alarm;
Step S522, judges whether to reach minimum particle size, if not, performs step S516, if so, performs step S524;
Step S524, after being assigned, being issued to correspondence physically, writing I/O and complete by I/O.
In the preferred embodiment, before carrying out the change of granularity of rolling up, the granularity of the assignment bit map in pond is simplified in first amendment, by all pieces of all set distribution state in pond.The change of granularity of volume is modified in conjunction with the above-described bitmap writing I/O according to minimum particle size record volume.For the block write I/O and cover, the mapping table of record volume.For the block write I/O and do not cover, bit_map corresponding for resource pool is set to assignable state.Fig. 6 is the processing flow chart of simplification volume change of granularity according to the preferred embodiment of the invention, and as shown in Figure 6, this flow process comprises the following steps:
Step S602, by current granularity, when resource pool not having had free space, starts granularity changing process;
Step S604, distributes new bitmap space, the assignment bit map of resource pool is switched to the bitmap arranged by new granularity, and all bitmaps are all set to distribution state;
Step S606 is that volume arranges a new mapping table according to new granularity;
Step S608, according to new granularity, in conjunction with bitmap volume being write I/O, travels through whole volume, generates new mapping table;
Step S610, if according to new granularity, block had I/O, then record was rolled onto the mapping relations of block, if according to new granularity, block does not have I/O, then the assignment bit map of the corresponding blocks on resource pool was set to free state;
Step S612, when resource pool discharging idle space, for etc. I/O allocation space to be allocated;
Step S614, in the process that granularity changes, new writes I/O if having, carrys out allocation space according to new granularity.Whether I/O first inquires about new mapping relations and generates, and whether if new mapping relations do not generate, inquiring about old mapping table has mapping item, if old mapping table has mapping item, carries out the switching of old mapping table to new mapping table, is switched to new mapping table process.If old mapping table does not have list item, then directly to process on new mapping table;
Step S616, after the process of a volume completes, the upper old mapping table of release volume;
Step S618, all simplification volume on traversal resource pool, after all completing granularity change, the granularity of whole resource pool has changed.
Fig. 7 is the granularity handoff procedure schematic diagram of simplification volume according to the preferred embodiment of the invention, and as shown in Figure 7, before switching, according to the granularity of 1MB, space distributes, and the remaining space of resource pool is 0.After switching, according to the granularity of 256KB, resource pool has discharged a large amount of spaces.Meanwhile, the sequential I/O of volume I/O upper the last period, the physical space of its correspondence is also continuous print.
