Method and system for storage virtualization
A system and method for providing storage virtualization (SV) is disclosed. According to one embodiment, a system includes a storage device having a tier 1 cache and a Tier 2 storage, an operating system and a file system having a Tier 0 memory cache that stores application data. The Tier 0 memory cache synchronizes the application data with the tier 1 cache and the Tier 2 storage.
1. A system, comprising:
a first storage device having a first Tier 1 cache and a first Tier 2 storage;
a first operating system; and
a first file system having a first virtual Tier 0 memory cache that stores first application data, wherein the first virtual Tier 0 memory cache synchronizes the first application data with the first Tier 1 cache and the first Tier 2 storage, and
wherein the additional first Tier 0 virtual memory cache synchronizes second application data through the first Tier 1 cache.
2. The system of claim 1 , further comprising:
a second storage device having a second Tier 1 cache and a second Tier 2 storage;
a second operating system; and
a second file system having a second virtual Tier 0 memory cache that stores the first application data, wherein the second virtual Tier 0 memory cache synchronizes the first application data with the second Tier 1 cache and the second Tier 2 storage.
3. The system of claim 1 , further comprising:
a second storage device having a second tier 1 cache and a second Tier 2 storage;
a second operating system; and
a second file system having a second virtual Tier 0 memory cache that stores second application data, wherein the second virtual Tier 0 memory cache synchronizes the second application data with the first Tier 1 cache, the first Tier 2 storage, second Tier 1 cache, and the second Tier 2 storage.
4. The system of claim 1 , further comprising:
a second storage device having a second tier 1 cache and a second Tier 2 storage;
a second operating system; and
a second file system having a second virtual Tier 0 memory cache that stores second application data,
wherein the first virtual Tier 0 memory cache synchronizes the first application data with the first Tier 1 cache, the first Tier 2 storage, second Tier 1 cache, and the second Tier 2 storage.
5. The system of claim 1 , further comprising a deduplicated file store, where deduplication happens at a block level.
6. The system of claim 1 , further comprising a deduplicated file store, where deduplication happens at a file level.
7. The system of claim 1 , further comprising a high speed network interconnecting the first tier 1 cache with one or more compute nodes.
8. The system of claim 1 , further comprising a low speed network interconnecting the first Tier 2 storage with one or more compute nodes.
9. The system of claim 1 , further comprising:
a first hypervisor running on the first operating system; and
one or more first virtual machines running on the hypervisor, a first virtual machine of the one or more first virtual machines having the first virtual Tier 0 cache.
10. The system of claim 1 , wherein the first Tier 1 memory cache is a solid state drive.
11. The system of claim 1 , wherein the first Tier 2 memory cache is a hard disk drive.
12. The system of claim 1 , further comprising a multi-boot module.
13. The system of claim 1 , wherein the first file system comprises:
a memory manager; and
an input output handler having threads, a Tier 1 storage mount and a Tier 2 storage mount.
14. The system of claim 1 , further comprising a second file system having a second virtual Tier 0 memory cache that stores second application data, wherein the first file system has an additional first Tier 0 virtual memory cache that synchronizes second application data with the second virtual Tier 0 memory cache.
15. The system of claim 1 , wherein the additional second Tier 0 virtual memory cache synchronizes first application data through the first Tier 1 cache.
16. The system of claim 15 , wherein the first Tier 1 cache includes, metadata, a T0 read cache, a T0 write cache and a T1 read write cache for the first application data.
17. The system of claim 16 , wherein the first Tier 0 virtual memory cache synchronizes the metadata, the T0 read cache, and the T0 write cache.
18. The system of claim 16 , wherein the additional second Tier 0 virtual memory cache synchronizes the metadata, the T0 read cache, and the T0 write cache.
