@jasonh : Thanks for sharing. Intel and SamSung are pretty much the leaders in the market. (Recent Gartner report June 13, 2014)

SSD Revenues

• Samsung $3.1b in revenue leads SSD sales - majority of revenue is attributed to PC SSD Sales.
• At #2 is Intel($1.4b), #3 is SanDisk($1.3b), #4 Micron($0.8b), #5 Toshiba ($0.6b)

In the enterprise, the SSD reliability reality may TOO match the report:http://itknowledgeexchange.techtarget.com/storage-soup/gartner-report-places-ibm-pure-storage-atop-2013-all-flash-array-market/ . Look forward to hearing from enterprise users of SSD (server admins, non PC users).

Enterprise SSD Revenues

• Total sales $4.4b, Hyperscale customers are purchasing low-cost SATA SSDs in huge volumes whereas Storage Manufactures are buying higher quality SAS SSDs.
• SATA SSDs: Intel lead producer of enterprise SATA SSDs, followed by Samsung, Smart Storage, OCZ and SanDisk.
• SAS SSDs: WD is #1 is SAS based SSD market followed by SanDIsk, Seagate, Toshiba and Hitachi
• PCIe SSDs: FusionIO is #1 followed by Google, NetApp, LSI and WD at #5. NOTE: Google, NetApp and Hitachi use their own PCIe SSDs within their own data centers - no external enterprise customers

With SanDisk's recent acquisition of FusionIO, they may pose a threat to Intel's SSD market.

It says - "Consumers should only be buying SSDs from Samsung, Crucial/Micron, OCZ (Toshiba), SanDisk and Intel. " What are your thoughts about it? And what about the Enterprise customers of SSD? Which vendors make it to the top of the list in enterprise - SSD vendors I mean. According to the link here http://www.dramexchange.com/WeeklyResearch/Post/2/3751.html it seems like Samsung, Toshiba, Micron, Sandisk, Intel and SK Hynix could be those - or am I missing something here?

@scottalanmiller : True. But realistically, what do you think how big a need is the latter in terms of say how many people use Software revamps of old hardware? I know firmware update is different from the case I have in point - say 'using SSD caching software to boost applications running on existing HW - requiring no upgrade / replacement to server HW, other than plugging in a small sized SSD to speed up apps and yet leverage investment in HDD'.

How soon in production? And do better SSD writes also impact SSD endurance positively?

What about the big there platforms.... vSphere, HyperV and XenServer. KVM is a pretty minor player and bare metal Windows and Linux are rare today.

Regarding Linux, especially Ubuntu and RHEL servers - are those rare too, these days?

You are asking the wrong question. You are asking him if they are big platforms, but you mean to ask if they are rare on bare metal and the answer is.... absolutely. They should be unheard of on bare metal. This is 2014, we are over half a decade since OS on bare metal is a niche use case.

I meant 'rare' as in 'hardly anyone uses non-virtualized Linux servers these days'
During early virtualization and 'cloud' days, many of the traditional IO heavy workloads did not move into virtual environments or on cloud due to latency issues. Now with standard cloud instance plans and hosted server plans increasingly available with 'SSD storage' that scenario for IO heavy workloads in Linux may have changed - in general. But are there say 20% of servers running Linux which are not virtualized today?Or is it <5% mostly small and outdated companies?

@Dashrender :-), oops! I think its my mistake. Until that particular response I had not 'noticed' the 'Quote' feature and used copy paste which may have resulted in this goof-up.

What are your experiences with IO bottlenecks? Have you considered addressing those cost effectively via Flash based or Solid State Drive (SSD) based caching software?

I can't think of the last time I didn't use some sort of flash cache or another. It allows for much greater bang for the buck when it comes to storage performance.

What SSD caching solution did you use and for which application/OS?

Typically a flash-based write cache on the host's SAS controller or VMware vSAN. The only bare-metal OS I run in a server environment is ESXi.

Great, thanks. What are some of the typical applications that benefit from write-caching in your environment?

@scottalanmiller said:

@shalooshalini CacheCade and VSAN primarily these days.

Thanks. So what kind of applications really benefit from your CacheCade deployment - are those primarily read intensive applications, say web servers or mostly VDI use case?

@alexntg said:

Most server providers offer flash caching as well on their controllers,

Yeah, but that is generic block level caching - not 'application' intelligent.

Depends on the use case - they aren't minor if you consider worldwide OpenStack Deployments today and its rate of growth. Ref: http://www.slideshare.net/ryan-lane/openstack-atlanta-user-survey

CacheBox's CacheAdvance SSD caching software is different from three key perspectives: 1. SSD vendor neutral 2. Block based fine grained yet 'application specific' caching which no one offers today. USP is the application specific modules technology. 3. Write-back caching (for transactional apps such as MySQL, MongoDB.

vSphere / Hyper-V / Xen: Those are not our first target environments - may come later.

Would you consider SSD caching to address IO bottlenecks?
