Hello, everyone!
If you ever worked on a VDI project, chances are pretty good that you face one or more questions about the performance, scalability, availability, data management, data protection and cost. and if you did, chances are just as good, it was your memory that helped or even causes these problems.
After all traditional (hardware-based) storage systems, not "aware application" are not able to distinguish the performance requirements of different workloads to ensure that each application at an optimum level performs nor are they designed to scale while linear improvement in performance.
Many of these systems are based on outdated storage architectures, bringing the data between volumes or arrays with replicating to provide high availability (HA) of critical databases, server and desktop operating system images, user profiles and user data. Such HA implementations typically inefficient memory utilization and storage and data management complexity lead.
can While all of the above strongly VDI installations impede, each of them can do it, make it difficult for organizations to realize the benefits of desktop virtualization.
In an effort to mitigate or "memory" issues, such as to prevent the above-described, the above ~~ POS = TRUNC run ~~ POS = HEADCOMP of other mission-critical workloads, many organizations have so far briefly, proprietary hardware-based storage solutions that have stood for the disposal, which seems to have as always been VDI disconnect when to implement "island" to further increase management costs and complexity
all problems remain, derail the VDI implementations often. rather, they have contributed to them.
Who (or what) can help you to solve or, better still, avoid these problems? has overcome
As long So -time Citrix Ready partner and now part of the Citrix organization Sanbolic (and its innovative Melio software platform) that memory problems helped hundreds of clients that have plagued since its advent VDI deployments. Since the early years of virtualization Sanbolic has the advantages announced software to be decoupled from the hardware, which allows companies to "tailor-made" storage solutions using industry standard components (compute and storage) to build, with intelligence (advanced storage and data management services) are solely by software that is 100% agnostic to the underlying infrastructure.
such software should seamlessly allow scale-out infrastructure and workloads, intelligent hardware use secured power levels to provide, where necessary, provide Tier 1 storage capabilities over a wide range of storage devices (Flash, SSD, improve HDD), the overall system fault tolerance, and greatly simplify data management and data protection measures. In addition, the software should be capable of these same capabilities to provide customers, regardless of whether they. The provision of VDI in a single data center or multiple data centers
Although Sanbolic hugged long and advocated the idea of enterprise-class storage and data management capabilities and services through the software supply, recently this concept "software-defined storage" and a consensus has been highlighted within the storage industry achieved by his label to refer to the term when describing the decoupling of storage and data management of hardware components. And while the term to software defined storage or SDS short, yet may be relatively new, outside of the storage industry for many, its benefits (eliminating the need to manage storage with proprietary interfaces on a per-array-based and license costs per function elimination) of organizations of all sizes are quickly realized as to the technology seen rapid adoption, continued.
For those who SDS, there are two basic approaches, with most providers of design and development of solutions based on an approach or the other. The following descriptions explain the premise behind each approach:
The first approach brings all storage and data management of the borders (housing) to move a hardware-based storage system to the host systems that actually use the memory. The primary advantages of this approach are the central management and scale-out infrastructures and workloads in heterogeneous storage environments from a variety of storage media (Flash, SSD, HDD) included arrays in various systems such as JBODs and storage housed, and the elimination of pay-per -Feature licensing models that require the customer space send a check providers have it every time need to access another function (ie, snapshots, QoS, storage migration, mirroring, replication, tiering, deduplication, etc.).
The first approach to SDS that enables organizations Converged Infrastructure , extremely useful to expand their existing storage infrastructures. consolidate By efficiently their environments, while to continue to use to realize customer significant reduction of storage and data management costs and complexity, and improved IT agility and operational efficiency investments in their legacy storage systems.
The second approach removes the traditional components and layers of a storage infrastructure, including storage arrays, switch fabrics, HBAs / CNAs and cabling and allows customers to their own storage systems with industrial Standard components computing and storage building provided with intelligence about the software. Consolidating computer and storage resources within the same housing and centralize the provision of storage and data services via the resulting hyper converged infrastructure reduces storage and data management costs and complexity, while the high CAPEX avoid and OPEX costs associated with the occurred use of external (SAN) storage arrays. In addition, the ability to hyper-converged solution that provides the level of fault tolerance for users of traditional storage arrays are used to RAID distributed over the systems to use.
Key granted by the second approach SDS advantages are the elimination of pay-per-feature licensing models and significantly lower TCO through the use of standard hardware components for centralized management and scale-out infrastructures and workloads heterogeneous storage environments of a plurality of storage devices exists. Organizations to build the new storage environments that offer high performance, dynamic scale-out, high availability, simplified storage and data management and enterprise-class storage and data services at a much lower cost than traditional, high-end storage array will probably want this approach SDS.
, the number of storage vendors (old and new) to examine industry analysts and experts, to continue to grow the advantages of SDS promoting on a daily basis, with many believing the technology has already establishing itself as a turning point (for the better) for the storage industry. Sanbolic Melio (now Citrix Melio) that in Citrix VDI (XenDesktop and XenApp) was provided environments worldwide for many years, has always been a 100% software-based solution, which provides customers the flexibility to offer either or both approaches on SDS in a unified management and scale out their virtual desktop infrastructure (and other enterprise applications) to achieve in heterogeneous storage environments.
A true SDS solution that provides the underlying agnostic hardware, Melio Advanced data services (ie database clustering, scale-out file serving, cost-effective DR, etc .) and tier1 storage capabilities (through multiple tiers of storage) , which can be applied dynamically, constantly meet changing business needs while ensuring the most efficient use of a customer valuable storage resources. SLAs that scale the performance of business-critical workloads seamlessly workload migration, intelligent data placement (data tiering), snapshots, mirroring and replication, automated data management and the ability to thousands of nodes and exabytes capacity (zero downtime guarantee) are all in the Melio platform included (no pay-per-feature licensing fees involved) .
to the above, Melio unique distributed addition (shared) found storage benefits technology that provides multiple servers with simultaneous read and write access to logical volumes, provides Citrix VDI customers the following:
- Simplified desktop and server image management and maintenance (PVS and MCS)
- Optimal memory usage
- reduced storage capacity requirements
- Improved virtual desktop performance (XenDesktops and XenApp server)
- Dynamic scale-out
- High availability (infrastructure server and / or storage capacity on-demand add) of desktop and server images, databases, user profiles and user data
- the ability to XenDesktop and XenApp deployments to span multiple data centers in active / active mode for load balancing and DR
in summary SDS is for storage in a new era initiated. As a provider of next-generation scale-out architectures for the modern data center and one of the first companies to offer a software-based solution delivered Sanbolic the benefits of SDS to its enterprise customers for many years. As a new addition to Citrix's portfolio of industry-leading technologies, Melio makes it easier than ever to realize the benefits of desktop virtualization for our customers.
