Autoart終於在2013年日本靜岡模型展上放出了這個”鴿子”，看樣子應該會成為Exoto以外的唯一選擇。

Saw this interesting post today, almost dated a year ago.

Q: Why does EqualLogic not support having active/active controllers?

A: This is a very good question. EqualLogic runs the active and passive controllers connected by a thick I/O pipe that effectively maintains the passive controller as a mirror of the active controller, this allows for near instantaneous failover in the event of a RAID controller failure – there is no need for the controller having to seize ownership of the failed controllers disks. This is supported by write cache mirroring and the write cache is cached to flash memory.

Note: The process of controller failover uses MAC spoofing and needs portfast and rapid spanning tree enabled on switches.

Q: Does EqualLogic support a Thin Provisioned LUN Space Reclaimer?

A: Not yet, this is in the pipeline.

Also came across this reply in Dell’s Forum.

Some terminology might be helpful here. Equallogic embeds their controller/filer/and disk shelves into one unit. The controllers are active/passive meaning only one controller is ever usable. The filer itself is tied directly to the disks. Other vendors handle this in different ways. Dell has chosen with the Equallogic system to do this.

Some vendors implement “raid” across the filers themselves (HP LeftHand’s network raid). Other vendors offer active/active controllers, or NetApp metrocluster functionality. Dell Equallogic does not.

We operate three Equallogic arrays in production use, and have never suffered a controller failure. When we preform firmware updates the unit reboots twice, taking it offline for 15 seconds. We do this during ‘quiet’ activity hours on our VMware, SQL Server, and Exchange clusters. They seem to handle the 15 second downtime without issue.

We have not seen the Active/Passive controller layout of the Dell Equallogic as a negative. The failure of an entire Equallogic filer (both controllers and both power supplies) is extremely extremely rare. There are no shared components between the controllers, they are functionally separate filers. The unit is right-sized for our organization and provides enterprise functionality at a fraction of the cost of a similar product that wold allow Active/Active enterprise level controllers, or Metrocluster functionality.

In summary:
> Dell Equallogic does not allow Active/Active Controllers, or full ‘raid’ between discrete units.
> Dell does not offer ‘Metrocluster’ or ‘Network Raid’ functionality like DRDB.
> Reboots of the entire SAN take 15 seconds (yes, really, as a customer, not Dell marketing) and do not cause any issue for us.

自從美國肌肉第一大廠GMP幾年前倒閉後，ACME(其實和GMP是同一個老闆)就開始了代替GMP之前計劃中但沒能夠如期推出的產品。

但是無奈最新的ACME產品的品質和幾年前的GMP還是差了一大截，就拿引擎蓋的鉸鏈開關來說，這兩款即將推出的1970 Chevelle SS 454  (LS6)竟然走回頭路用上了狗腿，當然油漆質量方面也遠遜於當年的GMP水準，可惜啊~造就了現今剩餘的那些GMP奇貨可居的現象，所以導致GMP在二手市場上的價格也連創高峰!

With the increasing popularity of my blog, I found more and more brutal force attack on WP admin login page. Today, I discovered a niche tool that actually does a bit of protection from this kind of automatic bot attack, of course, it won’t stop an experience hacker from trying.

今天經過雜誌架的時候看到了一個醒目的封面，青綠色Miura是我其中一台最喜歡的大牛，當然毫不猶豫地立刻買了下來。

這期更詳細地探討了幾乎所有有關於Miura的知識，更包括了那個困擾了牛迷近30年的謎團，也就是到底Miura是那位設計師的偉大傑作﹖也終於在此期客觀地揭露了答案。
