c**h 发帖数: 34 | 20 "比VMEM差远了"?
我们先不说 PureStorage 好在哪里,Violin Memory不好的太明显了。
从技术角度看,VMEM其实是一个纯粹的硬件公司。它主要的产品线,6000 Series Flash
Memory Arrays,是一款企业级存储阵列,却恰恰需要大量的软件features。一款企业
级存储阵列和一个简单磁盘阵列从硬件的角度来看可能区别不大。定义企业级存储阵列
的关键就在于一整套软件功能(enterprise feature set), 包括 complete LUN
management, thin provision, snapshot, replication, high availability, high
reliability etc., 以及对存储protocols支持和对不同平台的集成,象Vmware VAAI
etc. 所有这一些都是VMEM十分欠缺的。它去年才引进CTO of Software,试图弥补其缺
陷。从这个角度来说,他的技术还很不成熟。
VMEM也十分清楚这个弱点,它试图通过OEM其他存储软件公司的产品去实现其所缺的功
能。最近它接连和symantec, atlantis computing合作来集成一些重要的功能,但并不
成功。说到底,没有一家存储公司能够依赖别的公司核心技术成功。
IOPS,VMEM的纸面数据不错。但其仅仅只对aligned 4K block优化。在实际运用中优势
很不明显。尤其当用户IO size远大于4K(大部分应用),或block misaligned(VM
environment),其性能并不好。而且当他系统运行一段时间后,性能下降很快。你若
有耐心的话,看看这个评测:
https://www.youtube.com/watch?v=e750fTD4B3c&feature=youtube_gdata_player
从经济角度来看,VMEM劣势太大。它没有dedup和compression,导致其 $/GB 居高不下
。在真正产品销售当中,你会发现 $/GB or $/IOPS 通常会比 IOPS 更重要。除了high
performance这个niche market, VMEM很难跟别的FLASH ARRAY Vendors竞争。它现在
打下的市场仅仅只是因为现在Traditional High Performance Disk Array更贵更慢。
更何况它现在主要靠烧钱来占市场:去年他的revenue是$73.8 million,却烧掉$183
million;今年前六个月,revenue是$51.3 million,烧掉 $110 million.
从管理层的角度来看,它更是一团糟。CEO Donald Basile是一个极其傲慢自大的人。
他只关心捞钱和与fusion IO斗气(四年前被FIO kicked out)。去年他的收入是$18
million, 公司revenue的20%, 令人发指。今年他又获得额外5million股票($35~
50million),前提是它能够让VMEM在十月一日前上市。这也是VMEM一次又一次强行上市
的原因(两次失败,这次勉强成功)。
说到底,任何一家真正做FLASH存储的都不会比VMEM差。没有人把VMEM当作serious
competitor.

Not many DISK arrays have the 'inline' dedup capability. But the 'inline'
dedup becomes a mush-have feature for ALL-FLASH arrays. The reason that DISK
arrays don't have dedup is simply because it CAN'T -- dedup will greatly
randomize the workload, which none of current disk arrays could offer high
enough IOPS for dedup without sacrificing user performance.
FLASH enables 'inline' dedup, which makes all-flash array much more economic
. If you don't have, you can hardly compete with other flash array vendors.

【在 c**h 的大作中提到】 : "比VMEM差远了"? : 我们先不说 PureStorage 好在哪里,Violin Memory不好的太明显了。 : 从技术角度看,VMEM其实是一个纯粹的硬件公司。它主要的产品线,6000 Series Flash : Memory Arrays,是一款企业级存储阵列,却恰恰需要大量的软件features。一款企业 : 级存储阵列和一个简单磁盘阵列从硬件的角度来看可能区别不大。定义企业级存储阵列 : 的关键就在于一整套软件功能(enterprise feature set), 包括 complete LUN : management, thin provision, snapshot, replication, high availability, high : reliability etc., 以及对存储protocols支持和对不同平台的集成,象Vmware VAAI : etc. 所有这一些都是VMEM十分欠缺的。它去年才引进CTO of Software,试图弥补其缺 : 陷。从这个角度来说,他的技术还很不成熟。
