RNA v. In-Memory Databases

In-memory databases rely on RAM rather than physical storage in order to accelerate queries. However, IMDBs are limited to available memory, and do not make memory a shared resource. RNA's virtualized memory can hold terabyte data sets and return data in microseconds at high throughput to the application. Find out about RNAcache.

RNA v. memcached

Companies have turned to banks of memcached servers to store objects such as serialized database query results. But, unlike RNAcache, memcached servers are not clustered, do not share data sets, and can't take advantage of the unmatched performance of RDMA over high speed fabrics. Find out about RNAcache.

RNA v. Data Grids

Data grids allow clusters to share data sets, but impose a high management and associated performance overhead.  These grid solutions are difficult to integrate, debug and optimize, and remain tightly coupled to a specific application, which reduces flexibility. Architects who have implemented these solutions complain of the 'black box' software to which they have tied their application's performance, and typically experience underwhelming acceleration results. RNA Memory Virtualization delivers data to applications at near-local memory speeds with minimal application changes. Find out about RNAcache.

RNA v. Clustered File Systems

Clustered file systems, including NAS and SAN, consolidate storage into a separate bank of hardware from the application nodes. While these expensive, often proprietary, solutions do accelerate storage, they only marginally improve application performance because they are too many steps removed from application data in the server, and make no distinction between the working data set and historical record keeping. RNA's virtualized memory has the speed of local RAM at terabyte capacities for your business critical working data set. Find out about RNAcache.

RNA v. I/O Virtualization

I/O virtualization creates virtual network and storage endpoints which allow network and storage data to travel over the same fabrics. While these solutions can simplify cabling and reduce hardware costs, they do not accelerate the underlying storage or the applications connecting to them. RNA solutions work in tandem with I/O virtualization solutions to accelerate applications. Find out about RNAcache.

RNA v. Storage Caching

Storage caching appliances sit between application nodes and underlying storage, caching commonly requested files. These appliances are expensive, require dedicated rack space and additional power in your data center, and can only store file-based, not block-based, data sets. RNAcache's RDMA and high speed fabric deliver requested files, block and object based data directly to shared memory in the application nodes, pulling data from an underlying storage when neccessary. Find out about RNAcache.

RNA v. RAMdisks

RAMdisks are simply virtual storage devices within a single computer. While data can be retrieved very quickly from RAMdisks, they are limited in size to the spare RAM of the computer, and are not sharable. RNAcache allows you to create a file based memory space similar to a RAMdisk, but much larger, and sharable by many servers. Find out more about RNAcache.

RNA v. SSDs

Solid State Drives, or SSDs, are physical storage devices that store data persistently on Flash or DRAM chips, offering data access much faster than traditional physical disks. But these disks are expensive, can only store relatively small data sets, and are not shared or application aware. Accelerating storage alone only marginally improves application performance. For a true application acceleration solution, RNAcache provides smart, sharable data availability. Find out more about RNAcache.

RNA v. Virtual SMP

Virtual SMP solutions create a single virtualized server running a single operating system out of commodity servers. While suited to some processor-intensive scientific computing applications, these implementations require significant application integration and are not suitable for business environments - a failure in any one server requires a system-wide restart, while RNA servers can come on- and off-line with zero data loss. Find out about RNAcache.

RNA v. Multicast Groups

Multicast messaging solutions configure hardware network switches to distribute messages to preconfigured groups of recipients. Commonly used in financial services firms for distributing market data feeds, these solutions are complex and don't take advantage of RDMA to deliver microsecond messaging and transaction processing.
